- “We found Pete's lab diaries and stuff. Mr. Science was pulling a Jekyll/Hyde deal. He was afraid Debbie would leave him -so he mixed this potion to get super mas macho.”
- ―Willow Rosenberg[src]
Pete's formula was a potion concocted by Pete Clarner, a Sunnydale High student, in order to increase his strength and virility, though it also mutated him into a clawed monster. Initially, Pete had to drink the formula to transform, but eventually its effects became triggered by anger. In this state, Pete was powerful enough to face off against Buffy, a werewolf Oz and a feral Angel and do fairly well, although he was hampered by his inability to think beyond his rage.
Behind the Scenes Edit
- The formula's effects bear some resemblance to the serum from Doctor Jekyll & Mr Hyde, except that Pete appears to retain a degree of control over himself in both forms where Jekyll and Hyde were clearly different personalities.
