Powerful gravity-manipulating supervillainess.
Even when she was a child, Erica d’Monstressart was always regarded as gifted. Born into a wealthy family, from an early age she displayed an intelligence, social sense, and beauty that made her the envy (or subject of admiration) of everyone who knew her. But Erica was more gifted than even her most ardent admirers suspected. When she was still young, she discovered she had a strange ability no one else did — she could manipulate gravity. Smart enough to realize she shouldn’t tell anyone about this, or show off her abilities in public, she kept her superpowers a secret.
Given her power, and the way she was used to getting what she wanted when she wanted it, it would come as no surprise to an expert in super-criminal psychology that the idea of ruling the world crept into her head as she got older. Disguising herself with a mask, she began to test her powers against the Paris police, and then the French Army, and eventually other superhumans. She never found anything that could significantly challenge her.
Deciding it was time to declare herself to the world, in early 2000 she adopted the moniker Gravitar and designed a distinctive costume. She chose to start at the top, attacking and attempting to conquer the city of New York. The result was a battle with the Sentinels that tore up a huge section of Central Park and knocked over one skyscraper. When she realized she couldn’t breeze to victory the way she had in the past, she knocked the heroes away from her with a powerful gravitic pulse and fled at top speed. She vaulted straight into the Omega-class rankings of the Superhuman Survey in 2001.
For the next several years Gravitar lashed out at the world at random, seemingly still intent on conquering it but not taking her quest very seriously. She battled UNTIL, numerous superhero teams, and even villains such as Mechanon and Eurostar, defeating most of them handily. At best the forces of law and order could hope to drive her away in a petulant huff after thwarting her temporarily.
Since 2006, Gravitar has apparently become more serious and determined, though no one’s sure why. In October of that year she attacked Washington, DC, lifting the US Capitol five hundred feet in the air and threatening to drop it unless the United States agreed to her rule. Only fast action by the Justice Squadron and the Capital Patrol, and a powerful spell cast by the Drifter, prevented her from murdering most of Congress. Since then she’s made two more major attacks — one on Paris in 2007, and one in Millennium City in early 2010 — and narrowly been defeated both times. In these attacks she’s displayed a tactical sense and awareness of the potential of her powers that was previously lacking, leading some experts on supercrime to speculate that she’s received training and/or advice from someone (though she could simply have buckled down and focused on improving herself). The authorities are worried enough about her power and intentions that in 2008 UNTIL established a new special team, Project Newton, specifically to study and oppose her... and even that may not be enough to slow her down the next time she appears.
