A bit of spitballing: I think The Red Huntress's profile would combine really well with Memoria's. (Base Potency 10.) Huntress's power is all about hunting a target, and Memoria's is about teleporting to a marked place. Combined, imagine marking someone, and that mark letting you watch them at any time, teleport to them wherever they are, and become stronger in order to better fight them. We could make the most terrifying assassin on the planet!
...Maybe we should keep this one strictly theoretical.
