This is very, very, very wrong. As the Crossovers page clearly dictates, any and all interactions Black Hat has with the rest of the Cartoon Network cast would be considered a non-canon crossover, due to how nothing Black Hat ever has done for any character has ever been reflected in their appropriate shows. And as I've watched a few of these shorts, I can safely say that this is the case.
Also, using the argument of "there's nothing that says it isn't canon" is no excuse whatsoever. You must prove to us that there is proof that is can be used as canon. Otherwise, this whole thing can be thrown out.
