Oberon's story is the same as all the other Anti-Heroes: people important to her were killed by the G.O.D., and she wants them stopped. More than anything, Oberon wants herself. Himself. Themself. She's taken on so many forms since her life was destroyed that she can't remember the face she was born with, and the G.O.D. long ago erased all evidence she ever existed in the first place.
If a picture exists anywhere, it's deep within G.O.D. headquarters. Getting to it is another matter entirely, but with the G.O.D. in shambles after the Anti-Heroes' latest attacks, her moment has finally arrived.
She expected it to be a solo mission, though, not a joint venture with the most aggravating person on the planet. Oberon has policies about how close she gets to anyone. The Anti-Heroes are colleagues, not friends. She has no family. And she wants absolutely nothing to do with the infuriating Scones.
