Character History

Rachel Leighton was born in Austin, Texas on October, 31st 1985. In her formative years, she moved to the Lower East Side of New York City with her brothers Danny and Ricky and became was once a part-time sales clerk at a boutique, but later became a mercenary. Her brothers got involved with gang lead by a man named Bing and wanted to be included so she can watch over them. Upon claiming she would do anything to join the gang, Rachel was beaten up and apparently raped by Bing, who years later became the costumed mercenary Crossbones. She would later lose her brothers when they tried to go after him and end up getting themselves killed. Rachel later became a mercenary, Diamondback.

One of the members of the original Serpent Society, Diamondback was a seductively sly woman with expertise in hand-to-hand combat, gymnastics, and thrown weaponry, having been trained by Anaconda at one of Taskmaster's academies. Her gimmick was that she threw acid-laced, explosive, or poison-tipped diamonds at her enemies. After her first confrontation with Captain America, while on assignment to find and kill M.O.D.O.K., she was instantly smitten with him. Diamondback was later assigned to take Captain America into custody from the villain the Porcupine. In reality, the hand-over was a set-up so that Captain America could capture the Serpent Society. Realizing they'd been set up, Diamondback threw explosive-filled diamonds at Porcupine, damaging his armored battlesuit.

Marvel: Ultimate Alliance 2: Story

Her first in-game appearance is working with the other villains helping Lucia von Bardas attack New York. After that attack is thwarted, Diamondback is locked up and eventually ends up in the Negative Zone prison, where she and other villains are infected with Mister Fantastic's control nanites. The main operating network of the nanites later becomes sentient and seizes control. Iron Man, Captain America, and Nick Fury's team fight her, Whirlwind, and Moonstone at the prison's exit portal to buy Fury time to set up the prison's self-destruct as a last-ditch effort to stop the nanite-controlled villains from escaping and infecting more people.
