Destroy the world? why? I live here too, Conquer and Dominate sure but destroying it? nah.

Anyway, I would pick Thanos. why? Magneto will stab you in the back if you are not a mutant, Loki cannot be trusted (he's also overrated) and Ultron is a machine

^You know what? Conqueror is a much better term

Magneto, assuming I would be a mutant. Otherwise he'd probably crush my dreams or something

Ultron

Which one won't betray me.

Either thanos or magneto,if I was a mutant, I feel that magneto would lay down his life for me,and Loki would betray me the first chance he would get and ultron just wants to destroy all organic life

Ultron

Doctor doom

Magneto

Probably Ultron
