I do want to like revisit the vampires that turned him maybe, or like yes JUST MORE VAMPIRE THINGS. I almost want to turn someone else to have a vampire friend and also that would be really devastating for Jasper, but then that person would be stuck as a vampire and/or they would both get to turn back and that's the end of the monster party. idk. Has anyone else thought about it?
This also could be an opportunity to explore things like Monster Island and Monster Metropolis which tbh sounds like a generally good plot direction for anyone. Metropolis, though, might be a place where all the heroes kind of freak out like 'we must kill them all!' and Jasper is like 'nooo staaahp'
