I'll tell you what's going to happen...Ninja-Z will take him down with his unique zombie-brand of martial law. There will be an epic battle, but Ninja-Z will give it his all. Not because he cares about protecting innocent characters from this katamari-esque monstrosity...no, he just wants brains...arrgh, BRAINS!! And three brains is better than one, MIRITE?
Oh yes, there will be blood. Lawlz.
EDIT: Oh yeah, I think they should remain together. From what Hoffy said in the original topic Mr. Wrong would have lost by one vote if he hadn't removed his vote at the last minute. This way Mr. Wrong can continue on even though he would have otherwise been left behind.
That's my understanding of things anyway. As long as the character creators have no problem with this, I see no reason for anyone else to have any problems with it either. What's done is done.
