Hmmm. By on panel feats it seems that Sloth is the stronger of the two. But for some odd reason Zodd can fight on par with Skull Knight repeatedly who is easily a couple tiers above any Homunculus. I have to go with Zodd. He does hav a flight advantage too. P.S. Again I think FMA and Berserk are good matches for one another.
EDIT: Never mind. And before any mod gets tempted to lock this thread due to not having pics for the characters in this match, I'm relaxing the rule until the site lag issues we've been having get resolved.
