There’s also Nathaniel Richards (no, not that one, except also yes that one – hang on), born in the 31st century onto a post-scarcity world of plenty. Nathaniel was a genius, but was bullied as a teenager, and one day when he picked a fight with one of his bullies, Kang the Conqueror showed up to stop the fight.
Kang revealed that the bully was about to kill Nathaniel, and Kang couldn’t have that because he would cease to exist. Nathaniel, horrified at what he would become, uses his genius to time travel back to the Marvel Universe’s present and slap on a set of Iron Man armor, becoming the Young Avengers’ Iron Lad.
That’s two Kangs, if you’re keeping score at home.
Some time post-Iron Lad, Nathaniel was back in his future and bored out of his skull, so he decided to build himself a fresh time machine and travel back to the ancient past. He crashed his time machine in ancient Egypt and took over as Emperor Rama Tut.
That’s three Kangs.
