Rabbit Gang, lulz
Or Pilaf Warriors
Or Red Ribbon

Whatever, you have here some factions to get ideas from: http://dragonball.wikia.com/wiki/List_of_Factions

Edit: Or we can choose an animal or whatever, and make a dojo of it.
I think of Wolf school, because i love Wolf Fang Fist
there is the kanji for it:

Rabbit gang :D dont you think its to childish? :D we have come up with something original and unique... :P

It would be childish, but if this motherf***er touchs you, you morph into a carrot

Dude everyone Knows the Rabbit Gang and aren't we getting Rabbit Gang Costumes in the game?

Well there's 95% chance im moving here and I'm making a Guild....

Look for my first post of this thread, please post any good guild name that you think it will work for our TW Guild.

We should have a vote after we have some good names.

Rabbit gang for sure?
leader should have Monster Carrot Costume (or at least the mask, i think i wount wear the mask of the costume, but i like the costume without mask)

How about "New Rabbit Gang (however is translated in chinese here)"?

I got one, PING - players in game ... And Second could be incognito ... ^.^

Rabbit Gang was the baddasser faction in all dragon ball
