Pete's formula

{{Quote|We found Pete's lab diaries and stuff. Mr. Science was pulling a Jeckyll/Hyde deal. He was afraid Debbie would leave him -so he mixed this potion to get super mas macho.

Pete's formula was a potion concocted by Pete Clarner, a Sunnydale High student, in order to increase his strenght, though it also mutated him into a clawed monster. Initially, Pete required to drink the formula to transform, but eventually its effects became triggered by anger.
