Room for Playbooks:
The Brain
For your (ultimate) Reed Richards or Brainiac (Legion) archetypes. Some of them can be done with other books but I think it would be nice to have, right?
The Dark Legacy
My mother was a super villain but I am totally not. The delinquent can be this but I am more thinking someone that really wants to be good but can’t be trusted.
A bit more out there and probably not enough for their own archetype but I wanted to mention it.
The Wielder
They are reliant on a powerful artefact that changes them in unforeseen ways.
See Doctor Fate or sometimes Thor.
Wonder Twins?
Your powers don’t work alone. Might be problematic in gameplay though. Instead of a Twin the partner could also be Baymax though, right?
I would be interested in making some of them btw.
