This is probably the first time I've used the Big Three in a fight. Or is it the Big Four now? The Mainstream Team consists of Ichigo (Bleach), Naruto (Naruto, what else?), Luffy (One Piece), Natsu (Fairy Tail) and to round it out to five I'll add Maka from Soul Eater.
On the other team is Berserks God Hand. Void, Conrad, Ubik, Slan and Femto. Switch one for Grittith if you feel fit (I'd like to keep this 5 on 5).
Add Toriko to the main stream side and Griffith to the God Hand side.
