I'm not sure if Video Bomb fan characters (Unicornius, Tricksy) and the mouse character (not officially made) count as "canon characters"...

FatKat? Even more questionable, because he's more of a crossover character.

Note that all of them are one-shot guest/cameo characters.

Anyway...

Say, LOD, have you asked the, er, fan series creators about the above characters? What constitutes as "canon" or not is confusing when it comes to this. I mean, if the above characters do count, we may as well include Fall Out Boy members. That's the problem.
