About Oguro Iwao
Knuckleduster is an individual with a strong sense of justice and drive to do the right thing. He prefers to punch first and ask questions later, as he is willing to beat up people he deems to look suspicious on the slim chance that they may be villains, forcing his teammates to hold him back before he goes too far. Despite this, he has proven to be more intelligent and smart than he seems to be at first.
