Regarding the Suit Up ability: When you purchase a a character die with Suit Up, you may KO a character you control whose name matches one of the ones listed in the ability.
The questions I have refers to Suit Up - Iron Man.
1. Does the character title have to match exactly, i.e. only cards with "Iron Man" as it's title?
2. Does part of the name have to appear in the title, like for "Space Armor Iron Man" and "Hulkbuster Iron Man" ?
