This Is My Fav Zosan Trope

Sanji and Zoro are both men. They can't have a damn baby.

And Sanji doesn't even like men. He states this in canon several times.

I’m so sorry I can’t hear you over the sound of Zoro and Sanji kissing and being in love THEY’RE JUST SO LOUD *ANGRY FRENCH KISSING NOISES*

── .✦ Monkey D. Luffy:

The Straw Hat crew was anchored at a small island, taking a rare break after a long stretch of adventures. The sun was setting, casting an orange glow over the ship as you cradled your baby girl, Dawn, in your arms. She was only a few months old, but her presence already seemed to brighten every corner of the Thousand Sunny. Her tiny hands wrapped around your finger, and the sound of her soft giggles filled the air.

Luffy, his usual exuberance toned down just a bit, sat across from you, his eyes locked on Dawn with a mixture of pride and awe.

“She’s so cute, y/n,” Luffy said with his signature grin, his voice filled with warmth “Look at her! She’s already so strong! I bet she’s gonna be a great pirate!”

You couldn’t help but laugh softly at Luffy’s enthusiasm “She’s barely even walking yet, Luffy. Maybe let’s wait a few years before we start recruiting her into the crew.”

Luffy’s face lit up “Oh, at her age I already wanted to be the king of pirates!" He turns to look at you and your serious face kinda scares him "...Y-yeah, we should let her grow a little first! But she’s gonna be the best, I just know it! I’ll teach her everything I know!”

Suddenly, a loud voice boomed from the shore, and you looked up to see none other than your grandfather-in-law, Garp, strolling toward the ship with a big grin plastered on his face.

“Oi, Luffy!” Garp shouted, his signature Marine coat fluttering behind him “I heard you had a kid! About time you stopped being such a carefree idiot and started taking responsibility!”

Luffy jumped to his feet immediately, his eyes widening with excitement “Grandpa! You’re here!” He grabbed Dawn from your arms before you could even protest, holding her in front of Garp with the same proud grin he always wore “Look! This is my daughter!”

You stood up and approached them with a smile, watching Garp’s reaction carefully. Garp stared down at the tiny bundle in Luffy’s arms, his usual gruff expression softening as he regarded her.

“She’s tiny,” Garp muttered, squinting at Dawn, but his voice held a strange tenderness “I didn’t think Luffy could make something this cute.”

Luffy puffed out his chest with pride “She’s gonna grow strong, just like me! And she’s gonna be a great pirate!”

Garp grunted, crossing his arms “A pirate, huh? You’ve got a long way to go if you’re gonna make her one of your little nakama, brat.”

Luffy beamed, clearly not bothered by the teasing “I’ll make sure she’s ready! Right, Dawn?” He shook her gently, making silly noises that caused her to giggle. Dawn’s tiny fingers grasped at Luffy’s hand, and it seemed like the whole world stopped for a second.

Garp let out a low chuckle, his usual gruff demeanor melting a bit as he saw the deep love in Luffy’s eyes “Well, kid, looks like you’re serious about being a dad. I can’t believe it, but I guess you’ve really grown up. She’s got your stupid grin, that’s for sure.”

Luffy looked over at you with wide eyes, his face flushed with excitement “Grandpa likes her! He said she looks like me!”

You smiled softly, your heart swelling with affection for both your husband and daughter “She has your smile, alright” you said gently, brushing a strand of hair from Dawn’s face.

Luffy beamed, clearly feeling validated by Garp’s approval “I’m gonna teach her all kinds of stuff! How to eat a ton, how to never give up on your dreams, and how to make sure the meat’s always cooked perfectly! She’s gonna be awesome!”

Garp raised an eyebrow, the corner of his mouth twitching upward into a smirk “Well, she’s not gonna be a pirate, that’s for sure.”

Luffy blinked in confusion “Huh? What do you mean? She’s gonna be the greatest pirate ever!”

Garp crossed his arms, grinning mischievously “No way. I’ve seen what happens when you let brats like you run wild. She’s gonna be a Marine, just like her old grandpa.”

Luffy’s eyes widened, and he took a step back, shaking his head in disbelief “What?! No way! She’s gonna be a pirate! You can’t stop that!”

Garp laughed, thoroughly amused by Luffy’s reaction “Oh, I can see it now: ‘Little Dawn, future Marine Admiral!’ No pirates for her! She’ll be the one taking you down one day.”

Luffy’s face scrunched up in determination “No! You’ll see! She’ll be a pirate! And she’s gonna be the best one there is!”

You chuckled softly at their bickering, watching as Garp playfully ruffled Luffy’s hair and then glanced down at Dawn.

“She’s got a strong spirit, though,” Garp admitted with a sigh, softening just a little “I can tell she’ll be a handful, just like her old man. But I’ll make sure she knows the proper way to punch things if she ever tries to follow in your footsteps.”

Luffy grinned, not giving up on his dream “I’ll make sure she’s ready to punch things too—pirate things!”

Garp snorted and let out a deep laugh “Well, kid, you’ve got a good one here. Just don’t be surprised when she ends up in a Marine uniform one day.”

Luffy huffed but looked down at Dawn lovingly “We’ll see about that.”

As the sunset painted the sky with hues of orange and pink, you felt the promise of a new journey unfolding, one with your family at the heart of it all. With Luffy by your side and Garp giving his usual advice, there was no doubt that little Dawn would grow up surrounded by love, adventure, and laughter, her own future as bright as the sun setting before you.

── .✦ Roronoa Zoro:

Your daughter, barely a few months old, has her tiny fingers wrapped around his index finger, her grip firm, almost unrelenting. Zoro raises an eyebrow as he tries to gently pull away, but she refuses to let go, her tiny face scrunching up in determination.

“Damn,” he mutters, glancing at you as you sit beside him, amused “She’s strong.”

You laugh softly, leaning against his arm “Like her dad.”

Zoro doesn’t answer right away. Instead, he watches your daughter with an unreadable expression, his free hand absentmindedly running over her soft, wispy hair. The moment lingers, quiet, thoughtful, before he finally speaks again.

“No,” he says, voice low “Like her mom.”

You blink, caught off guard by the sudden shift in his tone. When you look up at him, you see the way his jaw tightens, the way his fingers twitch slightly against your daughter’s back. He’s thinking about something serious. Something deep.

Zoro’s gaze flickers to you, intense in that way only he can be “That day…” He exhales sharply through his nose. “And not just that day. The whole damn time. Pregnancy, labor... all of it. I thought I knew what strength was, but I didn’t. Not really.”

Your chest tightens. Zoro isn’t one to put things into words often, but when he does, he means every syllable.

“I couldn’t do anything at all,” he admits, still staring at your daughter’s tiny hand around his finger “I just had to sit there and watch while you went through all of it. No fight I’ve ever been in, no injury I’ve ever had... it’s nothing compared to that.” He finally looks back at you, eyes dark with something raw “You’re stronger than me, y/n, believe me.”

You feel your breath catch.

It’s not just the words, it’s also the way he says them, with complete sincerity. Zoro, who has trained his entire life to be the strongest swordsman, means it. He believes it.

You squeeze his arm gently, your voice soft “Zoro…”

He huffs, shaking his head as if the thought still overwhelms him. Then, his expression softens just a little as he looks down at your daughter again. She’s still gripping his finger tightly, completely oblivious to the weight of the moment.

Zoro smirks faintly “She’s lucky to have you as her mom” he mutters.

You smile, warmth blooming in your chest “She’s lucky to have you as her dad.”

He doesn’t answer right away, but you catch the way his grip on your daughter shifts slightly, gentler, but still firm. Protective. Always.

She might have his strength, but Zoro knows exactly where it comes from.

And he’ll never forget it.

Zoro started to be protective towards her since you first announced your pregnancy.

He’s that type of super stressed dads who keeps running around following every single thing she does so that he can catch her if needed. All this with always a big blush on his face.

But it’s not that bad that he controls her bec, in fact, right now, your one-year-old daughter is standing in the middle of the deck, holding onto Luffy’s index fingers as he swings her back and forth like a human jump rope. Every time he lifts her up, she squeals in delight, kicking her little legs mid-air before landing on the deck.

“Again! Again!” she demands, her tiny fists gripping Luffy’s fingers with ridiculous strength.

Zoro, standing nearby with his arms crossed, scowls “Oi. Don’t drop her.”

Luffy grins, stretching his lips wide “Don’t worry! I won’t!”

You, sitting on a crate just a few feet away, shake your head with a sigh “She’s fine, Zoro. Look at her, she’s having fun.”

Zoro doesn’t budge, arms still crossed “She’s one wrong step away from flying into the ocean.”

Luffy gasps, looking at Kazuki with sparkling eyes “You wanna fly?!”

“Luffy, NO.” you and Zoro shout at the same time.

Kazuki claps her hands “Fly!”

“NO,” Zoro repeats firmly, glaring at Luffy “You are not throwing my kid.”

Luffy pouts “But she’s got a strong grip! She wouldn’t even let go—”

“Luffy,” you say, rubbing your temples “let’s not test her durability today, please.”

Luffy sighs dramatically but doesn’t argue. Instead, he lifts Kazuki up and plops her on his shoulders, holding onto her tiny hands so she doesn’t wobble off.

Zoro mutters under his breath but doesn’t stop it. At least Luffy’s holding onto her.

Sanji chooses this moment to stroll onto the deck, cigarette between his lips but dropping it as he walks towards Kazuki “There’s my little princess,” he coos, hands in his pockets “You hungry, sweetheart?”

Kazuki, who has long since associated Sanji with food, beams “Yummy?”

Sanji grins “The yummiest. I made you something special.”

Zoro immediately frowns “What did you make her?”

Sanji raises an eyebrow “Relax, moss-head. Just some soft fruit and rice balls.”

Zoro doesn’t move “You sure there’s nothing weird in it?”

Sanji bristles, instantly getting in his face “Weird? She’s a baby, you muscle-brained swordsman! What the hell do you think I’d put in her food?”

You sigh, standing up to intervene before they actually start fighting “Okay, okay, both of you calm down. Sanji, thanks for making her food. Zoro, you really do look stressed, why don’t you go take a nap? I’ll stay with her.”

“I’m good, I’ll go later… don’t worry” he says softly but still watches like a hawk as Sanji hands Kazuki a tiny rice ball. She immediately grabs it with both hands and shoves it into her mouth, cheeks puffing out like a chipmunk.

“Good?” Sanji asks, kneeling to her level.

Kazuki chews, sways on her little feet, then beams “Good!”

You smile and ruffle her hair “Say ‘thank you,’ Kazu.”

Kazuki tilts her head, then garbles around the mouthful of rice “Fanku.”

Sanji clutches his chest like he’s been shot “Ohh, my sweet little angel, you’re so polite—”

Zoro scoffs “Don’t act like you raised her.”

Kazuki points a chubby little finger at Zoro and proudly declares “Dada’s idiot.”

Silence.

Then the crew loses it.

Luffy collapses onto the floor, clutching his stomach. Nami has to lean against a barrel, wiping tears from her eyes. Sanji turns away, shoulders shaking with laughter. Even Robin chuckles from where she’s reading in her chair.

Zoro stares at Kazuki, completely betrayed.

You, barely containing your laughter, kneel beside her “Sweetheart, don’t call your daddy an idiot.”

Kazuki tilts her head, as if deep in thought. Then, just as serious, she looks back at Zoro and says—

“Dada’s big idiot.”

Zoro groans so loud it nearly rattles the ship.

Luffy wheezes. Nami nearly falls over. Usopp actually falls over.

You bite your lip, but it’s no use, you’re laughing too.

Zoro glares at all of you “I blame all of you for this... y/n, stop it”

Kazuki, sensing she’s won, lifts her arms up to Zoro. He sighs, scooping her up, resting her against his chest. She immediately nuzzles into his shoulder, letting out a happy little hum.

“Dada” she murmurs.

Zoro exhales, the corner of his lips twitching despite himself. He presses a kiss to her hair, murmuring, “Yeah, yeah. You’re lucky I like you, brat.”

You step closer, resting a hand on his arm “You love her” you tease.

Zoro scoffs “Obviously… unlike you, she doesn’t know what she’s saying”

You go and leave a quick peck on his lips “You’re my lovely big big idiot”.

He blushes like crazy.

Kazuki looks up, sleepy “Dada?”

“Hm?”

She grins “Dada’s big big idiot.”

The crew howls with laughter.

Zoro sighs so deeply, but even as the teasing continues, he holds Kazuki a little closer.

She’s happy, safe, and in his arms. That’s all that matters.

That afternoon, you find them sleeping adorably together, in the same napping position. Smiling, you take a blanket and gently cover them both. Zoro stirs awake, thinking the baby has moved, something that makes you smile even more, knowing how hard it usually is to wake him. When he sees it’s you, he reaches for your hand and quietly invites you to join them, pulling you in for a cuddle.

── .✦ Vinsmoke Sanji:

Sanji is soft with her.

Softer than you ever thought possible.

You watch from the doorway as he sits on the edge of your shared bed, cradling your daughter so delicately, like she’s made of glass. His thumb gently strokes over her tiny fingers, his breath slow, steady, controlled. But his eyes hold something else.

Something hesitant.

Something uncertain.

Your heart tightens.

“She’s sleeping,” you whisper, stepping closer “You don’t have to be so tense.”

Sanji barely glances up “I know.”

But he doesn’t relax. Not even a little.

Instead, he just keeps staring at her, as if waiting for something. As if at any moment, she’ll change into something unfamiliar, something he won’t know how to handle.

You sit beside him, curling close, resting your head against his shoulder. One arm wraps around his waist, the other reaching out to trace the soft fabric of the onesie your daughter is bundled in. She shifts slightly, making a tiny sound, and Sanji freezes.

You feel the sharp inhale he takes. The way his fingers twitch, just barely, as if bracing himself.

And suddenly, you understand.

“Sanji.” You keep your voice gentle “What’s wrong?”

He exhales slowly through his nose “Nothing.”

You don’t let that slide. Not with him. Not when he’s never been able to lie to you.

You shift, pulling back just enough to see his face “You’re scared.”

His jaw tenses, his grip on your daughter tightening the smallest bit “Of course I am,” he murmurs “I’ve never done this before.”

You shake your head “No, I know it's not just that.”

He doesn’t answer, but he doesn’t have to. You can see it all over him, the weight of his past, the fears he won’t say out loud.

So you say them for him... “You’re scared of being like him.”

Sanji flinches.

It’s barely noticeable. A fraction of movement, a flicker in his expression. But you know him too well.

“I’m not,” he starts, but his voice falters “I mean—I would never—”

“I know,” you cut in softly “And she’ll know too.”

His breath shudders “But what if—”

“She won’t be like them, Sanji.” You rest your hand over his, where he’s still holding her so, so carefully “And even if she was, she’d still be ours.”

Sanji swallows hard “I don’t want her to be cold,” he whispers “I don’t want her to feel like she has to earn love. I don’t want her to think—” He stops, jaw clenching “Like I did.”

Your chest tightens.

You knew. Of course you knew. You knew how deep his scars ran, how much he still carried, no matter how much love he poured into everyone else.

You squeeze his hand “She won’t.”

Sanji shakes his head “You don’t know that.”

“Yes, I do,” you insist, voice steady “Because you are her father.”

That makes him pause.

“She’s going to grow up knowing love, Sanji. Because you give it so easily, so naturally. Because you would rather die than see her cry. Because when she wakes up at night, you hold her before I can even sit up. Because you—” Your voice wavers, but you press on “Because you are already the best father she could ever have.”

Sanji exhales, shaky, uneven. His grip on your daughter loosens just slightly, his thumb resuming its soft strokes against her tiny hand.

“She’s so small” he murmurs, almost to himself.

You smile, leaning into him again “Yeah. But she’s yours.”

That does something to him.

You feel the tension in his body shift, melting just a little. He looks down at your daughter again, something lighter in his expression now. Something less like fear and more like wonder.

“She’s beautiful” he breathes.

You kiss his shoulder “Like her dad.”

Sanji huffs, but you can hear the warmth creeping into his voice “I hope not. She deserves better than a troublesome cook.”

You nudge him playfully “She has a father who will love her unconditionally.”

Sanji doesn’t answer right away.

Instead, he shifts, adjusting his hold on her, drawing her closer. And when he finally speaks, it’s barely above a whisper, so quiet you almost miss it.

“Yeah, she has that.”

Your throat tightens.

You don’t say anything, just slide your arms around him, tucking yourself against his side, pressing a soft kiss to his jaw.

Sanji rests his chin lightly atop your head. He’s quiet for a moment, but you can feel the way his heartbeat slows, steadying.

Then, just as softly, almost like an afterthought, he murmurs, “I was easy to love. My father was just really bad.”

Your breath catches.

It’s not something he’s ever said before, not so plainly, not so simply.

But now, with his daughter sleeping in his arms, with you curled up beside him, with love so clear and so real around him, he finally believes it.

The fears won’t vanish overnight. The scars won’t disappear. But right here, right now, in the quiet of your room, with your daughter safe in his arms Sanji finally lets himself believe it.

He is more than enough.

And he always will be.

The next morning you wake up to chaos.

“Oi, oi, oi, CAREFUL!” Sanji nearly vaults over the table as Luffy lifts the baby girl high into the air, laughing as she squeals in delight “Luffy, she’s not a sack of flour, PUT HER DOWN!”

“She likes it, though!” Luffy beams, spinning in a circle with her in his arms “Right, mini-cook?”

His daughter giggling is the only reason Sanji doesn’t immediately drop-kick his captain into the next century. Instead, he clenches his fists and growls, “If you drop her, Luffy, so help me—”

“Oh, come on, love-cook,” Zoro snickers, leaning back against the railing “You’re acting like she’s made of glass.”

Sanji whirls around to glare at him “You grip your sword too tight, you sit too close, you BREATHE wrong, and I swear—”

“Oh no,” Nami sighs, crossing her arms with a smirk “We’ve lost him.”

Usopp nods dramatically “RIP Sanji. He used to be cool.”

Franky wipes an imaginary tear “Another victim of dad syndrome.”

Sanji ignores them, practically vibrating with anxiety as Luffy tosses the baby just slightly in the air before catching her again.

“LUFFY, I SWEAR TO ALL THE—”

You snort. Loudly.

And just like that, Sanji freezes.

His brain short-circuits because—oh.

You’re laughing.

Not a little chuckle, not a polite giggle. Full-on, tears-in-your-eyes laughter.

Sanji forgets about murdering Luffy, forgets about all the dumbasses around him, because you’re happy.

His shoulders drop. His fists loosen.

Then, as if sensing his shift, his daughter suddenly reaches her arms out for him.

Sanji immediately swoops in, taking her from Luffy and holding her close to his chest, pressing a soft kiss to her forehead “That’s enough flying for today, sweetheart.”

Nami smirks “Aww, the overprotective dad act is over already?”

Sanji barely reacts. Instead, he turns to you, watching the way you’re still wiping laughter from your eyes, and—

God.

If this is what family feels like, if this is what love feels like, then he never, ever wants anything else in the whole world.

The only reason she wasn't given a Raid Suit is because she could have obliterated her pathetic excuse of a husband to smithereens with it. Give her a gun!!!

I'm on a Sora roll lately and I don't know why. Not that I'm complaining.

Momofication...it's terminal

(silly lil self indulgent thing with my critter of a persona lolol) :p

:D

no one laugh….

Crocodad AU where immidiately after having left Dragon and his baby boy Crocodile finds an 11 year old Robin. And while he's 100% only recruiting her so they can make a beeline for the Poneglyph and Pluton in Alabasta by the two of them... Crocodile accidentally sorta kinda adopts Robin.

At this point Robin's been running for her life from the Government for three years so her deep trust issues and fear of betrayal are starting to take root in her little heart. Like perhaps they haven't taken fully over yet, and being still a child I'm sure Robin might've still had that genuine hope that she could find a safe place to stay in. But I'm sure the though of "what'll he'll do with me once he gets what he wants?" would be nagging at her at the back of her mind. Meanwhile Crocodile's struggling between the pain and hurt he's already gone through and given him his trademark trust issues, as well as the aftermath of The Dragodile Divorce. But he also has his Fresh Paternal Instincts and probably misses his baby. So when given a small, scared child who is running for her life, being chased by the very same Government that'll want his son dead if they ever find out about him... Yeah that might fuck with your brain a little

You know this post was supposed to be just that first paragraph and just a few footnotes from the following two paragraphs. And then I kept on Having Thoughts. And I kept on writing them down. And oh no what happened when did this post get so long (Look I was going to either kept on writing my Additional Thoughts in the tags or I just put them in the actual fucking post)

Like considder this: based on this one SBS, we can kinda tell that if Crocodile was given a chance to raise a child, that child would be a spoiled little shit, right

So in this scenario, where Crocodile's looking after lil Robin, would he be kind of torn? Unsure how to feel about her?

Because on one hand, this strange child would have the potential to not only ruin his plans, strip him of his Shichibukai Privileges by outing him and his plans to the World Government, but also put his son in grave danger by extension (if she found out about him having been involved with the Revolutionaries and/or having a child). But on the other hand, his paternal instincts could make him want to spoil this poor little girl rotten. But only because he needs to (perhaps literally) buy her trust so she'll behave. No other reason, he doesn't feel sorry for her one bit, no sirree. (But maybe he did feel sorry for her, since his son could very well end up exactly like her. Poor little thing) (Which is why he needs to nuke Marijoa out of orbit as soon as possible, no matter the cost, and this child can't get in the way of Crocodile protecting his son) (But also this is a child. Like how bad could she be. Besides all he really needs to do to win her trust is be nice and make her feel safe, right?)

Of course, while I'm suggesting Crocodile could have some parental instincts, realistically, he hasn't actually spent any time being, you know, a father to a child (looking after his newborn for an unknown though short amount of time aside), so it's possible he wouldn't even know how to parent Robin even if he wanted to, would he? (Like taking care of a newborn and an 11 year old kid aren't the same either) So if he was kind of just emotionally flipflopping between No Trusting Ever and It's Just A Kid for God's Sake, Crocodile trying to be nice to Robin to make her feel safe and then telling himself to stop being so soft and vunerable... Yeah that would make for an absolute mess of a relationship. (Not to mention, let's be real, dude's a scary motherfucker too, and a bloody giant compared to itty bitty baby Robin. He could keep on accidentally scaring the shit out of Robin (who would be On Fucking Edge To Begin With) by just Being Himself. Like for example, can you fucking imagine if he caught Robin trying to cheer herself up with a little "dereshishishi" only to tell her to stop because "it was stupid"? 'Cause I can imagine him doing that, and boy howdy would that make Robin feel bad)

Or who knows, maybe Crocodile was just Born To Be A Dad, maybe he just Fucking Gets It. Like Crocodile is canonically pretty good at manipulating people to do what he wants them to do (see: how he played Vivi like a fiddle), so knowing Robin's position and understanding how she feels, maybe he COULD completely nail how she needed to be treated. Not being too familiar but still making her feel safe and happy, knowing exactly when to be stern and when to spoil her, etc. Dude just goes off and wins the Dad of the Year Award while being a deadbeat dad himself. The only thing Crocodile would have to worry about then would be making sure HE doesn't get too fond of her. And certainly that could never happen, he's so in-touch with his own feelings and so grounded, he's not a softie, get outta here. Or maybe he does but never realizes until it's too late and good luck backpedalling on those emotions now dumbass

Alright so, the reason I went on that whole rmble is just that like. I'm so interested in the relationship Robin and Crocodile already have in canon. I'm so facinated and curious about how the two feel about each other, considdering they did spend 4 whole years of their lives together as criminal business partners, though neither ever trusted the other. A partnership that was only ended because Robin betrayed Crocodile, out of her own trauma. (God, I want to see these two "reunite" so bad, I want to know how they feel about each other now after the timeskip and Robin joining the idiot in flipflops who foiled Croc's plans)

My question here is just that... if they had met 13 years earlier, would things have been different? Especially if Crocodad Real? Because as I mentioned in the begining, Robin would've been on the run for only 3 years by this point, as opposed to 16 years before running into Crocodile. Simultaneously, this would be before Crocodile went onto spend an entire decade all alone, slowly losing his marbles in his emotional solitude. They'd both be emotionally traumatized, yes, but would it have been as bad in this scenario? Like I did start this post kind of joking about Crocodile adopting Robin, and for clarity's sake I don't think they'd have like a father-daughter relationship nececarily. But it would be a strange relationship still, because we'd have two broken people, both struggling to trust anyone. One who had lost her mother and her only friends, leaving her all alone and afraid while running for her life. The other a father who had just given up his son whom he probably missed dearly. Both having these holes in their hearts from loss of family, holes that could not be filled with replacements. But could they find comfort in each other anyway, because they still as people occupy similar roles to their respective loved ones? If they both could just get over those trust issues?

Okay I've been going off on the Emotional Side Of Things for this AU Concept, THERE'S PLOT TOO

So if Crocodile did pick Robin up like 19 years ago, that should be before he set up base in Alabasta, long before he had built is homebase and financial empire etc.

Now the thing is, while we don't know when, where and how Crocodile learned about the Ancient Weapons, Pluton specifically and how the lead on it would be in Alabasta... Considdering Crocodile did once upon a time aim to become Pirate King, it would make perfect sense if he had learned about Poneglyphs during his past adventures, as he would have needed to get the Road Poneglyphs to find One Piece. And while the World Government did bury the truth about why Ohara had been burned down and why Robin had been given her bounty (remember, the WG claimed it was because she had sunken a fleet of battleships, which she had not, it was because she could read the Poneglyphs), considdering this is a Crocodad AU specifically, you could totally make an argument Crocodile could've learned about what actually happened to Ohara from Dragon and co. So, just to make this AU work, you could just assume Crocodile learned about the concept of the Ancient Weapons from Dragon. And who knows, maybe he overheard the truth about why Robin had been given her bounty from Dragon too (maybe Dragon was able to get intel from Garp in secret) or while going to Marijoa himself to attend a Shichibukai meeting or something IDK.

Maybe he learned about Pluton being in Alabasta before finding Robin by accident, and maybe they made a beeline for Alabasta the second Croc recruited Robin. Travelling takes time and the guy would've most likely had to find an Eternal Pose to Alabasta just to get there (also canonically Robin didn't enter the Grand Line until her 20s so they should've met in West Blue probably, since that's where Ohara was) Or maybe Crocodile had to haul Robin around for a few months while looking for That Missing Piece of Information that would lead him to Alabasta. (Imagine the two travelling from like island to island, library to library, Crocodile trying to find that leads while Robin's just so excited about ALL THESE BOOKS (she's helping too with the research) (but to her, research is playtime, so she's just having the time of her life) (Also, notice how Crocodile's Theoretical Child is a fucking loser ass nerd? Yeah Crocodile would encourage Robin reading and studying, surely. And that would be fucking cute))

But like, once they set sail to Alabasta...

Sure, Crocodile could try to do it The Slow Way that we know he tried in canon, building trust and creating his little empire etc. But also, in canon, Crocodile couldn't have jumped into action head first because without Robin, even if he had found the Poneglyph he couldn't have read it and found the location of Pluton. Crocodile choosing to do it the slow way may have been partially because he didn't have much of a choise and it could've felt like the smarter move long-term.

But in this scenario, he already has Robin. Yes, he could do it the slow, secure way.

But what'd be there stopping him from infiltrating Cobra's palace and kidnapping him (in the night, when nobody suspects a thing), demanding Cobra to spill the beans lest Crocodile kills him and/or his pregnant wife* (*Vivi was born 10 months after Luffy so depending on how long it's been between Crocodad leaving Luffy behind and this scenario... Yeah either the wife is there, still pregnant, or there's a newborn Baby Vivi)

Like it'd be a risky move but depending on how ballsy Croc's feeling and how confident he feels in being able to kidnap the king without being noticed... Yeah he could probably do it. And I'm sure he'd have no problem killing Cobra either, if anything it'd be required if he didn't want the Government to find out he was out to find Pluton, and god knows Cobra would tell on Crocodile if left alive. I could see Crocodad being maybe a little iffy about killing Baby Vivi though (it's not like the newborn baby could report him to the WG anyways), but if nothing else, he just needs to be able to pull off the bluff of his life to convince Cobra to do as he's told. And we all know Crocodile's good at convincing people.

The only question is, how would Robin take that?

Watching Crocodile go into Full Murder Mode, hearing him say he'd kill a pregnant woman/a newborn baby if he didn't get what he wanted? Like yeah, I'm sure 11 year old Robin would be fine with that, that wouldn't make any alarm bells go off in her head at all, it'd be fiiiine. IT WOULD NOT BE FINE, SHE'D BE SCARED SHITLESS. That fear of "what will he do with me when he gets what he wants"? Well, Robin may not have found the answer to that question in particular, but she certainly found the answer to the opposite question, and it's not good

So say Cobra, kidnapped (perhaps with Baby Vivi) by Crocodile in the night, guides the two to the Poneglyph under the tombs. Crocodile puts Cobra out of his misery because he's not needed anymore. And he asks Robin to read the Poneglyph for him.

Robin, who has spent the last little while, be it weeks or months with Crocodile, him having become her "guardian", the thing keeping her safe. Crocodile, who has now shown how cold blooded and cruel he can be. Robin, who might be scared out of her mind. Of him.

And the Poneglyph says Pluton, the thing Crocodile wants, isn't there. It's in Wano.

What's she going to do?

EDIT: I wrote a sequel post, enjoy
