In the universe I made, Atlas Boy starts out totally hating Astro because all he sees is this equally powerful "traitor" hanging with disgusting "fleshies" "squishies" and "fat bags". Atlas is close minded and totally ignorant...till he discovers

Firefighters. Here for the first time in his life he sees what he's missed, heroes. Robot and human firefighters, untarnished, valorious beings who give life and limb for anything. Finally he starts to bust out of his closed world, though he's not quite ready to give all humans a pass.
As for Astro? Eh...he's tollerable but he's no way equal to Atlas, have to maintain some sort of self-superiority.
