Given his canon history is pretty heavy and dark, especially with regards to growing up in an interment camp, being experimented on and committing mass murder at twelve and dying at 17, I'm aiming for something a BIT LIGHTER for his au history.
I do think, however, that his mother is absent/died early in his life, and his father died around the time he enrolled in the Tellurian Institute of Advanced Exploration. Leaning towards a nod to his canon about undergoing experimentation by having him volunteer for more radical mods-testing and being financially compensated for it in order to go to school. I don't think this would give him a big edge (maybe some processing or healing stuff) but he'd have a ton of scars from all that! The biggest downside is he sweats more than normal due to fuckery with his adrenal glands.
