Great mixture
The only thing i didn't like about it was the pokemon-ness of it.. but I guess it works as a mode of battle to bring in everything else. I noticed lots of sounds from sonic 2 and 3, and the flower storm thing was a sound from Mario RPG.. along with him turning into a mushroom. The only 2 things im wondering- (1)- is the crazy psycho crack robot's multi strike arm, the sound effect of robo punch in Crono Trigger, and (2)- Was that final summon supposed to be like Bahumat Zero from FF7?
