Tatsumi is not taking his seeing as pills and poisons don't usually work on him. So, he'll just leave it.

So, prepare for a two headed big bad wolf (Or more correctly a large Crocotta)

Cube... I'm unsure of at the moment. I thought of him becoming some kind of Inugami but... he might take the pill.
Thinking Cube can be some kind of Kludde. (Shape Shifting dog with blue flame above it's head that devours people)

And Molossia will prob be a creature like the questing beast.
