Chimera Manticore

Chimera is a creature of some indeterminate species that sort of just... showed up one day. At least, as far as they know. Instead of trying to figure out their past, they seem much more interested in playing video games. But they can't keep their memories, and their second, meaner form at bay forever!

Chimera has many powers that they currently aren't aware they have, and a few they are aware of. Most notably, they "poof" into a second form of themself, Night Chimera (or Nightmera). Nightmera has their own interests and personality that tends to clash with Chimera's. Chimera is also able to shapeshift, though the extent of this power is unknown. They have vague memories of "spawning in" and have only one possession- the picture of someone that they find suspiciously familiar... but they can't place why.
