Bevatron was a mutant with the superhuman ability to increase the personal storage of bio-electricity within the cells of his body. Bevatron could then channel this energy into radiant discharges of high-voltage energy from his hands.
The French-born Bevatron was a member of the Hellions, the team of adolescent mutants formed by the Hellfire Club's then-White Queen, Emma Frost, joining shortly before the Hellions' clash with the New Warriors. During the clash, Bevatron battled Firestar atop the roof of the penthouse home of the New Warriors' leader, Night Thrasher. A blast from Firestar aimed at Bevatron's feet knocked him off balance, and he fell, sustaining serious injuries.
Bevatron recovered, only to apparently be among those Hellions slain by the time-travelling Trevor Fitzroy during the villain's assault on the Hellfire Club. Recently, Bevatron was revived with an alien techno organic virus.
