Wait... Wildchild?  As in Kyle Gibney?  I don't think so...  Besides, I don't think I would want a "poor man's Wolverine" outside of Sabertooth.
Anyway, I'd like to continue the conversation about my theory that this character is not new - but Wolverine as a teenager.  It's definitely a possibility, seeing as how this character has been so hard to define for us.  He's pretty much a cookie cutter comic character which is making our heads turn.
Also, I believe PX2 mentioned that this character may be Geldoff. I think if Kirkman took care of that loose end, I'd really enjoy reading about that.  Although I think Bendis is gradually going to take care of it (Seeing as how he mentioned Latveria coming up with their own super soldier program), I think if it was taken care of in UXM it would be a much better story.  We'll see, though...  Like I said, heads are turning!
