Jake had gills on the sides of his neck. He was a student at Smallville High School. He was a shy boy with a crush on Lana Lang. While Lana was swimming after hours in the school pool, Jake inexplicably grabbed Lana's ankle and appeared to drown her.
Van shot him in the head and in turn saved Lana from drowning. After Van's father had been killed by Tina Greer, Van had begun stalking and killing metahumans.
