Selena: AU Post-Apocalypse (Uncolored)

So... I know Ooo is already post-apocalyptic, but Hal9000 says there will be like an end to the Earth, and that gave me this idea! This is an Alternate Universe where the apocalypse has occurred, and not many people survived... So ask her stuff!!!))

Name: Selena
Age: Late teens, early twenties (It's been so long, she can't remember)
Height: 6 ft
Weight: Unknown
Occupation: Nomad

Bio: She has pretty much given up all hope that anyone she cares about is alive. The apocalypse occurred when she turned 15. She doesn't usually meet anyone born before the apocalypse, let alone anyone she would know.

Skills/Personality: Unlike this universe, where she is extremely shy, self-conscious, and wouldn't hurt anyone unless they hurt her; this Selena is cold-hearted, ruthless, and doesn't show emotion often. She knows how to use her weapons, and uses them often. She is very stealthy, flexible, and lethal. She could be called a hero, but most are too frightened of her to even thank her.
