Sebastian is a Chilean-American who was born on February 3rd, 1993, making him thirty-two. In 2013, he was given the death penalty for the framed deaths of nine people. Research company Urbanshade took him in and experimented on him in 2015, injecting him with anglerfish, shark, blue whale, and sea snake DNA. He became 10'6. Company's goal? To add gills in humans.

Seb was put in a cell on Hadal Blacksite, an underground prison facility, ran away. He's a shopkeeper now. Snarky, irritable, wise.
