Hey I discovered something so cool about the battle Party Image data . All you have to do is be Megaman counter and turn into somebody else . Than you do something like D-hero Megaman and Protoman . Br-rush Megaman and Colonel .This helps a lot but it wastes your number of times changing into other navis .
There was this time where Protoman and Magnetman attacked at the same time I don't know how that happened it was called M-Z

Megaman and Protoman : D-Hero
Megaman and Napalman : D- Vulcan
Megaman and Colonel : Br-Rush or B-Rush
Megaman and Knightman : B-Shot
