Phillip Michael Gerard (aka Mike) is a character in the TV series Twin Peaks, portrayed by Al Strobel.
Mike is an inhabiting spirit similar to the primary villain of the series, Bob (Frank Silva), who was his partner in serial murder.
After committing several rape/murders with Bob, Mike had a religious epiphany and repented, cutting off his own arm to rid himself of a tattoo that read "Fire Walk With Me", which symbolized being touched by "The devilish one".
In contrast with Bob, Mike only ever appears in the visual form of his host, traveling shoe salesman Phillip Michael Gerard.
In the 2017 revived series, Mike (credited as Phillip Gerard) appears once again in the Red Room as a sort of guide for Cooper, who is transported back into the real world after being imprisoned in the alternate dimension for 25 years.
