Gen 14-
Holly "Breakdown" Denton: Occasionally known as Goo, Holly has the ability to disassemble molecules, seemingly causing objects to melt into goo. She was formerly a member of Gen14. As of Gen13 vol. 4, #32, Holly has sacrificed her life to save Caitlin and was once more seen as an incubating clone.
Amber "Ditto" LeRoux: Not much is known about Amber, only that Holly refers to her as a typical airhead. A former Gen14. Her power is infinite multiplicity which allows her to make an unlimited number of copies of herself.
Guillermo "Runt" Sandoval: Not much is known about Guillermo. A former Gen14. His powers allow him to grow and shrink.
Lance "Hardbody" Wieder: The second-in-command of the former Gen14. Not much is known about him at this point; during a fight between him and Gen13, his face was scarred by Holly, who was defending herself. He and Windsprint were left behind in order to recover. His powers include augmented strength/stamina and increased dermal density which makes him super-strong and near-invulnerable. Doctor Cross (the maker of the current Gen program) expressed interest in potential offspring between him and Caitlin Fairchild.
Shaqira "Windsprint" Johnson: The speedster of Gen14. She was shot in the head by a crazed general and believed to be dead. However, it is revealed that her enhanced physiology also included a heightened metabolism allowing her to survive the gunshot. She and Hardbody had been originally left behind in order to recuperate.
They were creations of Chris Claremont for Gen 13 (2002-2004)
