The original Iron Man villain!
This petty third-world prison camp dictator captured Anthony Stark after
Stark was crippled by a booby trap. (Stark was checking out some of his
weapons designs in battlefield use.) He later coerced Stark and noted physicist
Professor Ho Yinsen
to manufacture weapons for him. Unbeknownst to the tyrant, Stark
and Yinsen constructed the original Iron Man
armor to save Stark's life from a piece of
shrapnel that was lodged near his heart.
Chu's continuity was changed
over the years. First, it was revealed that he was a pawn of the Mandarin
and most recently he was "resurrected" along with the brain of Professor
Yinsen (IM Annual 2000)!
