A hybrid between Gorilla and Bat, Gelsi is the daughter of Brantor Videlsky. She was currently being chased down by a mutated Brantor known as Camazotz, trying to implant an embryo into her. In Story A, she is chased down by the Tyrant Loveland Frogman and took off her pendant to give it to Eris during a chase. In Story B, Camazotz succeeds in implanting an embryo into Gelsi's body, but Gelsi herself would be cured later on during a train escape. She would eventually meet her two big brothers Garzon Heights and Blista Videlsky.
