Gamma Jack (A.K.A. Handsome Jack) was a superhero in The Incredibles.
Gamma Jack was one of the Supers targeted by Syndrome for Operation Kronos. The Operation Kronos database assigned him a threat rating of 7.9, the second highest after Mr. Incredible (9.1). Gamma Jack did manage to destroy the fifth version of the Omnidroid during the training sessions for Operation Kronos, but was promptly killed by its successor model, the Omnidroid 6.
Easily recognized by his wave-like hairstyle, he was a favorite of the ladies (his original name being Handsome Jack) and was prone to megalomaniacal impulses, believing Supers to be a "superior race." These impulses and traits caused the NSA great concern, putting him under close "A Level" monitoring as a result. He was also a picky eater.
Radiation Bursts: Gamma Jack's superpower was the ability to create controlled bursts of radiation, from focused burns to complete disintegration. The maximum range of this high-intensity burst is 100 meters, before a sharp intensity falloff.
