Mack

Overview Mack is a security guard that works for the GRN and is stationed at the company's Northern Branch in Alaska. He participated in a resource war between the ORNGE and GRN as the Green Team's communications officer after the death of his predecessor, Jimmy. He quickly became chief of security after the death of Chris, since his role of communications office technically made him Leo and Joey's superior officer. He was killed in action by Maylor, only to be resurrected by the Necromancer. Mack served as the Necromancer's mole in the Green Team for a time, though Mack soon betrayed him and assisted in the Odd Men Out's escape. He joined them again to take on the crazed mercenary Butler, then became a major participant in Flim's plan to stop the Apocalypse. Personality

Mack is abrasive and rude to just about everyone around him. He has an inflated ego, often taking credit for things he had no involvement in, such as the Green Team's victory against the Oranges in the pilot episode. He's extremely hard on his teammates and would subject them to rigorous training sessions. He would pick on Joey in particular for his smart alec attitude, often saddling him with Tyler, who he would task to annoy him to no end. That being said, his tough training was why Flim appointed him as the new leader of the Green Team, knowing that it would push the Odd Men Out to achieve their goals.

He also seems to look down on Leo for being an immortal, often referring to him as a "freak". Ironically, he ends up undead over halfway through the first season (courtesy of the Necromancer), with superpowers to boot, and appears to enjoy the power. This could indicate that he had a change of heart or secretly envied Leo's immortality and would take his frustrations out on him.

Mack does have a good side, albeit buried beneath his unpleasant attitude. The Christmas special in season 1 revealed that his father was a drinker and his mother was too busy to give him any attention, which could have influenced his current behavior. He was willing to make a truce with the Oranges and participated in the festivities, after some coaxing from Chris' ghost. He's also protective of his teammates, to an extent, as he saved them from Butler, citing that only he gets to push his team around. He's even willing to help the save the world, so long as he gets back at the Necromancer. Trivia
