Marvel Avengers Assembly : The Sinister Substitute

A group of new teachers arrives at Avengers Assembly, and not everyone is who they seem! Kamala, Doreen, and Miles are back at Avengers Assembly for a new semester! When Captain Marvel announces she's adding staff to the school, the students aren't sure who could possibly join -- but it looks like Cap went above and beyond, and the school is full of new teachers! With all these new teachers, it's hard to keep track of who's teaching what, and what they're supposed to be learning. And some of these teachers are really not acting like heroes at all, but more like super-villains?
