Scrapped character ideas included Silver Surfer (his fighting style — energy blasts & zooming around on his board—didn't mesh well with a fighting game system), Dr. Strange (too similar to Dr. Doom), Mr. Fantastic (his stretching abilities were too hard to draw into sprite form), Daredevil (not compelling as a fighter), Black Widow (Same reason as Daredevil), Hawkeye (Not enough abilities for a moveset) and Scarlet Witch (too overpowered). Dr. Strange, Black Widow and Hawkeye eventually made their way into later games in the series.
