This box may be a less-than-optimal pick for a limited X-Men force. But Beast is cool so it doesn’t matter.
Beast comes with head/arm variants for angry mode and bookish mode. I like the idea of him (literally) hanging out instead of fighting. I asked my kid what book he should be reading. She immediately answered Harry Potter. So there we go.
Mystique is not X-Men affiliated. But the relatively open faction rules of Crisis Protocol means that doesn’t have to be a problem.
