Adopted from Nyxium on DA. In "Pet Projects", he is the co-leader of a group of stray hybrid kids.

He was abandoned by his owners when he was young and was tossed from gang to gang until he finally landed up in Shay's old gang, the Mountain Lions, as an errand boy.
Tristan is emotionally closed-off, sarcastic and has definite trust issues, especially where humans are concerned. He also struggles with his self-esteem because of being thrown away so many times. He’s had enough experience with humans and in different gangs to build up some street savvy, which he puts to good use as Shay’s second-in-command.

Relationships with other OCs:
Shay - He's built up a level of trust with her that he doesn't have with anyone else. She's the only one he fully opens up to.
Everett - Everything's a contest with him, and he gets on his nerves.
Veli - He's a good kid, but his naivete is a pain point.
Avery - He's a bit high-strung, and Tristan feels like he has to walk on eggshells around him; but he admires his resilience.
