PS2 version of SSB

[Psygnius]

Hm... while I was in Japan last week, I noticed a new fighting game on the PS2 that was similar to Super Smash Brothers. Except it contained DBZ, One Piece, and Naruto characters. It was something something, D.O.N. The DON part stands for the title of each anime used.

Anyone have any more info on this game?
