Lady Deathstrike's dad was a failed Kamikaze pilot (he flew his plane into an American ship and didn't die), who wore a mask from the end of the war. When he was talking to Bullseye (this was the guy who gave Bullseye his adamantium skeleton and from who Weap0n-X stole the process from), he was asked why he wore the mask, was it because was he all burned and stuff. He replied that his face was fine, he said that he was filled with shame at what Japan had become since the war.
