Arclight was once a soldier serving in American peacekeeping forces during a conflict in Southeast Asia. The experiences there severely traumatized her, and she retains bitter memories of that place. She used her rage to fuel her bodybuilding, which she further used to augment her mutant abilities.


At some point, Sontag became a member of the Marauders, a team of superhuman assassins brought together by the mutant thief Gambit when he was in the employ of the enigmatic Mister Sinister. On Sinister's orders, the Marauders massacred the underground community of mutants known as the Morlocks. Arclight is possibly the cruelest of the Marauders, taking great delight in murder and mayhem and always eager to prove herself up against an opponent with a reputation. In the course of the massacre, the Marauders, including Arclight, clashed with various superhuman champions, including the superhuman mutant adventurers known as the X-Men and X-Factor. Her physical strength was gained half due to her mutation and half to her obsessive body-building, her defense against the wartime nightmares which still plagued her in secret.

Arclight and the rest of the Marauders originally died during the demonic invasion of Manhattan that came to be known as the "Inferno", but Sinister had the technology to clone the Marauders thanks to him retaining samples of their DNA. Thus, Arclight continued to appear among the Marauders in all subsequent activities, including their battles with Cable and X-Man, each time on behalf of Mister Sinister.

During the track of Threnody and X-Man, she was killed by Riptide, manipulated by Nate Grey, after having been herself lured into killing Blockbuster.[1]


For a brief time, Arclight served as a member of the Femizons, an all-female superhuman army led by the other-dimensional warrior woman known as Superia. During this time, Arclight clashed with the super-soldier Captain America and the mercenary named Paladin.

The 198

After the House of M events, Arclight joined the mutant refugee camp on the grounds of the Xavier Institute, the inhabitants of which came to call themselves the 198. She seemed to have a romantic relationship with fellow Marauder Scalphunter, and didn't hesitate to use this relationship to cement her tenuous position as second-in-command.

Marauder again

For unknown reasons, Arclight left the 198 team and rejoined her former longtime team the Marauders. Arclight, along with the help of the Marauders and new members Mystique and Lady Mastermind attacked the X-Men unexpectedly.

She later joined the Marauders gathered by Da'o Coy Manh against her will as the others, and attacked the X-Men. She was eventually found dead, having killed each other with Harpoon.[2]


  • Shockwave Generation: Arclight can direct a wave of energy by striking a victim with her hands or feet.

  • Superhuman Strength: Arclight possesses superhuman strength allowing her to lift approximately 50 tons.
  • Superhuman Durability Arclight possesses a high degree of durability, protecting her against such damage as impacts caused by being struck by superhuman opponents.
  • Superhuman Endurance Arclight's endurance is far superior to a normal human's.
