Here follows a list of recurring characters that feature in the show, accompanied by a brief description in order to provide some context. This is all canon.
Barry from Barry’s Burgers: In episode 17, “Eggs and Gravy World of Adventures“, George moves into a bird’s nest next to a motorway burger van called Barry’s Burgers. Barry is introduced as the proprietor of the establishment and the two strike up an unlikely friendship, bonding over their depressing lives. Barry is a fat man who sleeps in his van with a foil blanket. He surfaces again soon in episode 21, “Who Cares, Let’s Talk Burgers“, when it transpires he has risen to the role of Police Chief thanks somehow to the gossip he has acquired in his burger van. Episode 28, “Who Blocked Tim Burton’s Toilet – A Christmas Mystery“, cements his role as Police Chief when he is called in to perform a cavity search on Queen Elizabeth. This leads to another unlikely friendship and the duo appear together in episode 31, “Prince Philip: Fury Road“, where they enter and ultimately win a “preparing and then consuming massive tonnage of burgers” competition.
Michael Cera: A possibly fictional version of the real life Canadian actor, Cera has appeared in so many episodes it’s almost impossible to list them all. His probable debut comes in episode 6, “The Burger Hulk”, where Fred hires him to be in the new Cillit Bang (a cleaning product) advert. Cera is seen to be blown up in the desert by a fleet of fighter jets to demonstrate the product’s awesome cleaning power. However, all is not as it seems as he comes back from the dead in episode 14, “Uncle Dickson Rescue Mission“, to kidnap George’s uncle and hold him ransom. This is the start of his transition into the plowdypod’s greatest nemesis and a bitter feud is born. A further example of this is in episode 22, “Once Upon a Bean in Mexico“, where it is revealed he has been training for years to become a professional dancer on Strictly Come Dancing, all so he can embroil Fred in a sex scandal. It comes to light in episode 27, “A Reanimated Corpse Bonanza“, that Cera’s evil dithering power is fueled every time someone celebrates Christmas too early. He is stopped in his tracks by the skeleton of Elvis.
Xanet: Fred’s French wife who first appears in the fourth episode of Series 1, “A Spicy Walkers Wedding“. She is a Spice Girls superfan and demands that they play at their wedding. To pull this off Fred arranges the nuptials to be sponsored by Walker’s/Lay’s crisps. Roger Federer is his best man. She makes her second significant appearance in episode 26, “A Tale of Two Nutters“, in which they have just had their first child. She has a long list of marital demands including that controversial French actor Gerard Depardieu babysits for them.
