Okay, So I've Read The Spider-man: Across The Spider-verse Artbook, And There Is This Fantastic Passage

Okay, so I've read the Spider-man: Across the Spider-verse artbook, and there is this fantastic passage on Earth-42 that gives context to the dimension, Miles G., Uncle Aaron and the Sinister Six.

“Miles comes face to face with a parallel world version of his own in Earth-42 – an alternate reality where he never gained superpowers and where his Uncle Aaron is still alive. “We wanted to craft this moment where Miles encounters this powerful figure in his life that he loved so much and he lost," says director Justin K. Thompson. “That's when he realizes that he is not really in his own dimension, as well as the gravity of what he has lost. In this reality, Aaron has had to shake off his life of crime and became a surrogate father figure to Miles.”

The artists changed Uncle Aaron's outward appearance to reflect this new reality and convey how he has changed. The Uncle Aaron of Earth-42 has a little gray in his beard. His clothing still has the old “cool streetwear” vibe, but he has a more sophisticated and older look. In this alternate reality, the Sinister Six have been able to flourish and take over the world. “We wanted to create a world where it felt like Aaron and Miles G. Morales [this reality counterpart to Miles Morales] are the only heroes.”

It's a much darker version of Miles' original home. So, we looked at comic book artists who epitomized that sort of noirish world - artists like Frank Miller, Sean Gordon Murphy, John Polygon, where there is heavy use of black and colors sort of recede behind the dark shadows. The powerless version of Miles is still capable and efficient and has great acrobatic and physical prowess. We also needed Miles to feel trapped in this dark world. We wanted to leave the audience with the burning question: ‘How is he going to get home?’ It was just exciting to see the development of this world to underscore all of these narrative choices we were making.”
