Adrian Lynn was crippled in a deadly car accident. She tried to recover the use of her legs via an experimental adrenal gland transplant. The treatment worked, but she lusted for more power and continued the treatment until she gained superhuman strength. Seeking revenge against She-Hulk for putting her husband in prison, Adrenazon disguised herself as She-Hulk and implicated her in crimes.
After the serum caused her to have a mental breakdown, she began to believe she was the Sensational She-Hulk.
After having a flashback, the serum overwhelmed her and she passed out. She blocked the Sensational She-Hulk from being stunned by guards from the Tombs.
Later, after the serum had worn off, she accepted her husband's guilt and the Sensational She-Hulk accompanied her to his grave.
As Adrenazon she had superhuman strength, speed, durability, and stamina. All of these factors are at sufficient levels to engage She-hulk in battle.
The treatments left her mentally unstable. In her normal form, she is paralyzed from the waist and confined to a wheelchair.
