Kang the Conqueror

Nathaniel Richards, mostly known as Kang the Conqueror, is a time-traveller and a major antagonist of the Avengers. Nathaniel Richards is a descendent of Reed Richards, Mr. Fantastic but records have shown that he has connections to Victor von Doom. 

Because of his frequent time-traveling, he has inadvertently created a variety of divergences in himself at different ages. These variations range from, Pharaoh Rama-Tut, a Pharaoh that rose to power in 2900 BC to Iron Lad, a 16 year old Nathaniel that sought to prevent the development of Kang the Conqueror.
