Mayor Story Arcs
However, unbeknownst to the New Mutants, the government took the babies into their custody. They were passed over to the care of the armed forces who treated the babies as potential weapons. Project Purgatory was formed to take the infants to Limbo where time moved faster than on Earth. In Limbo, the babies were brutally experimented on, often with triangular slices of skin being removed for testing.
Project Purgatory was caught off guard by an attack of Limbo Demons led by Belasco's self-acclaimed daughter, Witchfire. During the attack, the children managed to escape their bonds & fought the demons, successfully killing them all. However, the confused message that was sent out indicated that the children had been killed. Therefore, lost in Limbo with no means to return home, Project Purgatory continued to mould the mutant children into perfect living weapons.
During some down time after the events of the Second Coming, the New Mutants were unexpectedly taken into Limbo by Magik. She could sense that Pixie had been kidnapped, and set out to save her. However, Magik & the New Mutants were attacked. The mutant children had spent the last 20 years living in Limbo, and they had learned to attack individually & in a group.
Powers & Abilities
Timothy's hands & forearms open up to reveal porous exhaust valves from which he can expel copious amounts of energy through. The drawback being he cannot compensate for when the blow-back throws him in the direction opposite of where he points his limbs. The beams emitted have both a concussive as well as propulsive effect, wherein he can not only use them as a means of ranged artillery to tag his opponent from a safe distance. He can also use it for lateral ignition allowing him to achieve a form of rocket propelled locomotion he can use to tackle and fly into intended targets like a battering ram.
