Yes, King Boo for ASMW5! If you want an idea, you could make King Boo's boss like Newer DS where he chases you; that's what I've been planning to do for a while. Awesome stuff Emul! Can't wait for ASMW5!
I'm just here to say that this super world Was one of my favorite in all the traditionals super world. This super world + all the ASMW series are just AMAZING!!!
