Yeah, but who really knows though? I feel like we haven't seen Toffee's full combat potential (on his own without the whole dark magic wand infusion thing), yeah he is pretty much immortal but without prep time and meeting a new enemy he might lose. Not die just lose. Since Vlad can go intangiable and fire beams, possess bodies and all that Toffee might just walk away like what happened with young Moon. I do see Toffee coming back though after figure out a way to combat Vlad's ghost form- Toffee seems to have a lot of pride and vengefulness to me. But man that would be one hell of a crossover!
