Sinister is a system
Stark is an engineer at his core.....If you need a weapon of mass destruction he's the first person you go to see. He's a builder that's always tinkering with things in his shop.
T'Challa is more of a theoretical physicist. He's driven by a desire to know how reality itself works and push the boundaries of what we're capable of.
Stark made a machine that allowed him to split the Phoenix Force into fragments, which is insane when you think about.
T'Challa created an entirely new field of science called Shadow Physics that he's using to make breakthroughs in teleportation, communication, and god knows what else.
Whats shadow physics? He on some reality breaker shyt?
