I'm way behind on this meme but finally got it done. Though the meme is with related or somewhat similar cartoon / game characters I wanted to make something out of my trio of villain. Now I kind of wish I could justify using the fusions because I rather like the look of a few of them.

I'm particularly fond of the Tar Justin one, since hypnotic shape shifting slime would be OP as hell.
