It is, it is... although, Joker tended to be grumpy to most in the group. There was a blossoming friendship between him and another, although the roleplay collapsed before it went too far.
My favourite part was that all of the characters were a result of blending human and Pokemon DNA. My character's Pokemon partner didn't go easily and never truely blended his mind with Joker's, and they had routine conversations inside his head. :3 Contrary to Joker, he was consistently cheerful, and while Joker had all physical control it was his Pokemon that did all of the jazzy moves. Joker gets mad and wants to destroy something? Nah, his Pokemon's not in the mood. ;D
So it's in no way a similar idea then? xD
