The Guardians of the Galaxy may be able to stand toe to toe with Ronan the Accuser, Nebula and Korath, but they were easily vanquished by 5-year-old Mia Grace Montross. The pint-sized Marvel expert, who made her Jimmy Kimmel Live! debut in December, returned to the show last night to face off against the stars of Guardians of the Galaxy in a trivia challenge. The result was ... well, about what you might expect.

The whole video, posted below, is worth watching, but the highlights are definitely Chris Pratt's faux-serious performance and Vin Diesel's glee in his apparent confirmation that the game is rigged, only to discover he was hitting the buzzer too hard.

Directed by James Gunn, Guardians of the Galaxy opens Aug. 1.
