As The Man of Muscle Mystery, Flex Mentallo's powers are apparently vast but ill-defined. In a general sense, Flex can affect reality by flexing his muscles, in a reverse form of mind over matter. In the most extreme exertion of his power, he was able to transform the Pentagon into a circular building for a brief moment.
When Flex uses his power, his "Hero Halo", a shimmering projection of the words "Hero of the Beach", appears above his head.

Scott W. Pilgrim is the 23-year-old protagonist. He is the bass player for the band Sex Bob-omb with his friends Stephen Stills and Kim Pine. Though initially an unemployed slacker, he later gets a job as a dish washer (and food prep trainee) at The Happy Avocado vegetarian restaurant. The character's name was inspired by the song "Scott Pilgrim" from Plumtree's 1998 album Predicts the Future. He believes that smoking is evil, and claims not to drink, though flashbacks show him drunk and he later begins drinking socially. Scott seems to suffer from memory problems, which his friends chalk up to his stupidity, though the memory problems began after his break-up with Envy Adams whom he dated through college. The series also references a mysterious "dark side" of Scott's personality which he avoids as much as possible. He is initially devastated by his break-up with Envy Adams, and begins dating Knives Chau before meeting Ramona. The two begin dating, but Scott is plagued by Ramona's elusive past and her "7 evil exes" led by the mysterious "Gideon", all of whom challenge him in succession for the right to date her.
