Inferno

There are actually two villains that go by the moniker 'Inferno'.

Inferno I
Inferno is a power-suited villain with flame throwers built into his suit. He was beaten by teenaged heroes, who intervened when a dispute with his ex-partner Deluge turned violent and spilled into the streets.

Inferno II
Originally held on Tranquility, Ingrid Heller AKA Inferno, was broken out by the Time Pharaoh to help him with recovering some lost data during the Lost Time plot. Prior to her incarceration, she had been captured in Los Angeles, after attempting to burn the city down.

During a fight, she severely damaged the antiquities wing of the art museum in Colonial Bay.

She is still at large.

Ingrid is a svelte blonde in a red and yellow costume, cut to be quite revealing, with a plunging neckline. Her outfit includes opera-length gloves and thigh boots. Her hair is shaved on one side, and flopped over the other way, over one eye.
