Any character you want, already made, or not.
It is an RPG like that, but wit a few differences.
I will post a kind of checklist and you have to explain an attack for each of those parts.
You don't have to post animations, but you can.
Safuran: 'OMG!, it's a Pikachu'
Hitsugaya uses Ice Beam.
Pikachu has fainted.
I am still making it.
You can be a villain in it.
You just post an action every turn.
You can turn on the group, or commit suicide (Probably not this option.)
You can switch characters, just post a comment saying you are.
