Added all but one character,need some help with this one(spoiler)

I've created chracter pages for all the bosses and supporting characters so that people can go and fill them in but there is one chracter that only appears for 2 minutes in the game that i did not catch his name. The one I'm missing is the zombie kid that shows himself somewhat before and after the  Matt Helms fight. His name is mentioned by Silvia afterwards but so only says it once.

It is supposed to be Matt Helms. Sylvia talks about how Matt was burned as a kid and before he died, sold his soul to the devil. The boss you fight is supposed to be his part of the deal. The little kid is actually Matt Helms, since he died as a child.
