After graduating from the Aegis Inc training school, Acid petitioned to join a special group of fighters trained in counter-guerilla warfare. While he is highly skilled in all aspects of combat and tactics, he is unfriendly and gruff, earning him his call sign "Acid."
Having come from a merchant background, Acid sides with the right of Aegis Inc and the other corporations who wish to take over the governance of their country.
Keen Eyes was born into the fighting heritage of her people, but after her parents were killed she became a ward of the state and was sent to corporate schools after showing promise in childhood testing. Eventually she forgot her heritage and supported the Corporate Government. However, after completing her training with Aegis Inc, she became apprehensive about fighting against the same guardians of peace that her own parents were a part of.
She wears a mask to cover her face, in fear that she will give away her mixed feelings about Aegis Inc's current mission to eradicate The Corps. Her tendency to only show her eyes has earned her the call sign "Keen Eyes."
Aurochs is the son of a Corpsman, when peace had seemed to come to their country, his parents encouraged him to study abroad where he made an impact at his university as a star footballer. When he returned home he discovered his parents gone, both killed in an attack by Aegis operatives.
Utilizing his natural athleticism, he began working as a free agent, making small tactical strikes against Aegis Inc operations. He was eventually caught and to be put to death, but during a Corps raid on an Aegis facility, they found and released him. The Corps had known his parents and asked him to stay with them and continue to fight to uphold the old government.
Despite being a footballer, Aurochs is an enormous man and intimidating to anyone of normal stature. His massive size and seemingly limitless stamina earned him the call sign "Aurochs" for the giant oxen of yore.
Tarantula lost her parents at an early age and was moved into a corporate schooling and orphanage facility. After being adopted by a wealthy business tycoon she was given a comfortable home and a life at an excellent school. However, when her adoptive parents soon had a child of their own, they began to neglect and mistreat Tarantula. When she could take it no more, she took the revolver her father kept in his study and murdered both of them.
Put into a juvenile penitentiary, she earned her nickname of Tarantula for being devious and ruthless. She eventually devised a plan to escape and join with The Corps in an effort to prevent men like her adoptive father from gaining control of the government.
