Ironman vs Chika Tanaka
Chika Tanaka was one of the major players in the Iron Man anime, but I’m sure that we all knew that her story had to come to an end at some point. Nothing from the anime could really stick since it was more of a side story. (Exceptions can be made of course, but I assumed that most of the original characters would be written out of the picture) Chika Tanaka is a pretty skilled adversary and her speed/power levels are not that bad. That being said, Ironman still has the edge thanks to his impressive array of armors. Ironman wins.
