- It's not like I want this to happen to me. You gotta help me, Doc. You help me or- gyaahh! You help me or I'll rip out your throat before you could even blink.
As a kid, Mac's mother was the one who supported the family the most. She was a very successful lawyer and Mac's father was a High School Football Coach, very close to getting fired. After he was laid off, he began giving Mac lessons in fighting, and he eventually became even better than his father. Over the years, his parents began growing apart and eventually got divorced.
Not long after the divorce, his father moved into an apartment and began drinking heavily. Mac would take care of him, and he actually preferred being with his father, rather than his mother. However, one night, his father got very drunk and attempted to beat Mac, but he used his martial arts skills to take down his own father. Aside from the shock and confusion, Mac learned he really loved fighting.
Not long after his father was arrested for working in a meth lab. At school, Mac began getting in fights on purpose, angering people, hurting them, he'd do anything to feel the adrenaline. The principal told him if he was going to keep acting up, he would be expelled, but Mac cursed at him and said he was dropping out. It wasn't long until Man eventually became a professional MMA fighter under the name "The Lizard".
During one of the biggest fights of Mac's life, his mutation began acting up. His hand starting becoming scaly but it would change back and forth. Mac was distracted and almost lost the fight, but instead of finishing it he ran away, trying to stop what was happening to him. He quickly stole a cab and drove himself to the lab of Doctor Curt Connors, Oscorp's top scientist. He forced him to develop a cure as quickly as possible, but when he injected Mac, it accelerated his mutation process, immediately turning him into the scaly monster he is today. He got out as quickly as he could and began hiding in the sewers in shame.
