Kieron Masterson was a veteran who'd lost his right arm and eyesight in the Vietnam War. With no real means of employment after the war, he took to begging on the streets of Seatle. He ended up inadvertantly gaining superpowers after being fed off of by the alien parasite Lissik. With his new abilities, Kieron teamed up with Green Arrow and they managed to drive Lissik out of the city. Kieron would go on to join the Blood Pack. He was later killed by an imposter Prometheus.
Powers and Abilities
As Hook, Kieron Masterson gained the ability to charge his hook-hand with plasma-like energy that could cut through most anything with ease. He also gained a form of infrared radar sight, which allowed him to see heat signals. His costume seems to manifest much in the same way as his energy hook.
