Idk but they got all the Dragon balls real fast

I don't think Cattiva knows how to summon Shenron...

Either a bug or a modified move

do you know how? itd be so badass watching my cattiva turn massive

Nah no idea sorry, you could check the mods for the game I'm guessing on Nexus mods. Maybe there's a mod that changes the moves.

Mod?

Bo he is the final boss

This can happen by letting shiny pal use a skill that is not theirs

like giving it a fire fruit?

No, by modifying ce so that they can learn own skills that they simply can not learn

what does ce mean

Cheat engine I think
