Fictional character biography
Darren Cross is a millionaire and the founder of a successful corporation, Darren Cross Haulage, which rivals its unidentified top competitors. Darren was diagnosed with a heart condition due to overwork, and had to use an experimental nucleorganic pacemaker in order to save his life. The pacemaker was a success but enhanced Darren's circulatory system, mutating his body and giving him superhuman abilities. With a side effect that overuse causes the burning out of his heart, Darren went through various heart transplants, which led him to capture surgeon Dr. Erica Sondheim to replace his heart and to abduct "donors" from the slums. This attracted the attention of the second Ant-Man looking for Sondheim in order to save his own daughter's life. The resulting battle with Ant-Man burned out Darren's heart, as Sondheim had reimplanted his old, worn-out heart prior to Ant-Man crashing the surgery.
However, Darren's body was revealed to have been kept in a cryogenic state as his son Augustine Cross, having taken over as the family company head after his father's death, later became obsessed with bringing Darren back to life and eventually forced Dr. Sondheim to help. Enlisting Crossfire's assistance, Augustine had orchestrated Cassie Lang's capture as the girl's heart is required to withstand the unique conditions when transplanted into Darren. While infiltrating Cross's company to rescue Cassie, Ant-Man came across his restored nemesis. Darren engaged in combat against Ant-Man while Ant-Man buys time for Sondheim to transplant another heart to Cassie. Darren is ultimately forced to flee with his son when the Pym Particles now in his body caused him to shrink down.
As part of the All-New, All-Different Marvel, Darren Cross was later approached by Power Broker II to demonstrate his latest "Hench" App by hiring Whirlwind to kill Ant-Man. However, Cross was unwilling to give Power Broker the 1.2 billion dollars he demanded for investment in the Hench app. This caused Power Broker to cancel the demo and cancel Whirlwind's assassination on Ant-Man.
Cross later represented his own company when he attended a meeting at the Universal Bank with Tiberius Stone of Alchemax, Wilson Fisk of Fisk Industries, Sebastian Shaw of Shaw Industries, Zeke Stane of Stane International, Frr'dox of Shi'ar Solutions Consolidated, and Wilhelmina Kensington of Kilgore Arms where they discussed Dario Agger's and Roxxon Energy Corporation's plans to exploit the Ten Realms of Asgard. Darren also saw the arrival of Exterminatrix of the Midas Foundation who knocked out Dario and declared herself a new member of their assembly.
In order to combat Ant-Man, Cross recruited Egghead to work for him at his company. Egghead helped Darren control his Pym Particle abilities by creating the Yellowjacket armor for him. Cross, Egghead and Crossfire attacked during his nemesis's trial in Cassie's place, but were engaged by Ant-Man, She-Hulk (as Scott's defending attorney), Miss Thing, Grizzly, Machinesmith, and Stinger. Cross was defeated by Stinger, which led to Peggy Rae's final approval of Scott's superhero life and Scott's acquittal in court.
Powers and abilities
Darren Cross's pacemaker made for his heart gave him superhuman abilities like slightly superhuman strength and increased sensory perception (especially eye-sight); but the side-effect has it burning out each heart that is transplanted into him. After gaining Cassie Lang's Pym Particles-equipped heart during the heart transplant, he gained size-shifting abilities with so far no control of it. It was shown that he can grow when angry and shrink when calm.
In the Yellowjacket suit, he can use his own Pym Particles to power the suit as a quantum weapon.
