Robbie is a sarcastic, arrogant, goth teenager with a bad attitude, who is Wendy's ex-boyfriend and serves as Dipper's biggest rival over her affections. He's the lead guitarist in his band Robbie V. and the Tombstones.
Robbie's first seen in a picture on Dipper's suspects board in "Headhunters." He makes his first physical appearance in "The Inconveniencing," driving up with Wendy's other friends to pick her up from the Mystery Shack. He boasts to Dipper about spray painting an explosion onto the water tower. When Dipper points out that the graffitti looks more like a muffin than an explosion, Robbie glares at him. Robbie takes the passenger seat on the ride to the Dusk 2 Dawn convenience store, pushing aside Dipper and saying he always rides shotgun. During the group's stay at the store, he acts very condescending towards Dipper. He makes fun of Dipper when he hesitates to jump the fence, and doesn't think Dipper can get them inside the store when his own efforts to open the door prove to be pointless. Once Dipper gets the kids inside, he's seen partying with the rest of them. When the ghosts attack, he's one of the only teenagers not to be taken. However, he's not seen when Dipper does the Lamby Lamby Dance to save the group.
Robbie then appears in "Double Dipper," at the Mystery Shack party hanging out with Wendy. He ignores Dipper and shows Wendy his new guitar. Seeing him as an obstacle between him getting to dance with Wendy, Dipper and his clones lure Robbie away from the party by stealing his bike. However, at the end of the episode, Robbie comes back and chats with Wendy, ruining Dipper's plan.
Robbie starts dating Wendy in "The Time Traveler's Pig," which sets up the plot for Dipper to start time traveling to prevent it. During an alternate version of the day's events, Dipper successfully wins Wendy a stuffed animal, causing Robbie to become jealous and walk away, pretending not not care. When Mabel's enemy, Pacifica, wins Mabel's pet pig, Dipper decides to time travel back again after he realizes he'll break Mabel's heart if he doesn't. At the same time, this causes Robbie to be dating Wendy again. He's then humiliated when Mabel's pig, Waddles, scares him into backing into a tub of hot water, causing his skinny jeans to shrink.
In "Fight Fighters," Robbie becomes Wendy's official boyfriend. While putting up flyers for his band, Robbie notices Dipper's crush on Wendy, and he tries to call Wendy to tell her Dipper's secret. However, Dipper breaks Robbie's phone to prevent this from happening, causing Robbie to challenge Dipper to a fight at 3:00 in Circle Park. When Dipper unleashes Rumble McSkirmish from an arcade game, Dipper uses Rumble as a bodyguard to scare off Robbie and put a stop to the fight. When Rumble encounters Robbie, he nearly kills him. Dipper tries to stop Rumble from seriously injuring Robbie, and he successfully does so by facing Rumble in a battle. After Rumble's taken care of, Robbie's about to punch Dipper, when suddenly he decides not to fight him, and the two agree to hate each other in silence, rather than to physically show their anger, lest they both lose Wendy for it.
Robbie's seen again in "Summerween," visiting the Mystery Shack with Wendy. The two inform Dipper of a party later that evening (though Robbie doesn't seem very enthusiastic about telling him). Robbie seems extra moody in this episode; he spends most of his screen-time talking down to Dipper, and is even punched in the arm by Wendy because of it. At the end of the episode, Wendy mentions him again; Robbie had to leave the party early, because he swallowed a lollipop stick-first and got sick.In "Boyz Crazy," Robbie didn't show for a date he had planned with Wendy, then comes into the Shack the next day and asks if she'd like to go to Lookout Point with him, to which she reacts angrily. She begins talking about breaking up with him, and, panicked, he takes out a CD of a song he claims to have ripped off from some band and plays it for her. She is willing to go with him after this, and is happy. Dipper, however, is suspicious and ends up finding a hidden message in the song and playing it for Wendy and Robbie on their date. Robbie immediately tells Wendy that he had no idea that message was there and tries to say he ripped the song off from the other band anyways, thinking that will fix the problem. Instead, she becomes furious with him and breaks up with Robbie on the spot.
In "Gideon Rises," he unsuccessfully tries to win Wendy's heart back again, and still appears to love Wendy. Wendy doesn't return his feelings; She walks away, and Robbie chases after her.
In terms of personality, Robbie is a stereotypical moody teenager, laid back and apathetic. He is condescending, especially toward younger individuals (i.e. Dipper). His careless attitude makes him negligent of others' needs, thoughts, opinions, etc., though he does express a certain—albeit limited—degree of concern for Wendy. Like Dipper, he is anxious to win Wendy's love, and this mutual goal only fuels their fierce, incessant rivalry. Robbie is known to be reckless, prideful, and dishonest, as well.
Since the first time Robbie met Dipper, he has been condescending and arrogant around his younger counterpart, making fun of virtually every trait about him and everything he does. In a short while, they begin competing for Wendy's attention, highly angering and upsetting Dipper when he began a relationship with her. During this time, Robbie made sure to brag to and about Wendy at every possible instance around Dipper, with the two never stopping their feud, even in front of Wendy (save for their short-lived "Cold War pact"). After a time, their brawling cost Robbie his relationship.
Robbie and Mabel lack a formal rivalry, but nonetheless are enemies. Observing the teenager's snobby attitude, she sees him as a jerk, being an object of ridicule herself on occasion. Since Mabel gets entangled in her brother's love life, she has been known to sabotage Robbie to help Dipper in his quest to win Wendy's love, although she becomes less concerned with this over time.
Wendy and Robbie first met at a birthday party when they were in 5th-grade, where Robbie pulled her pigtails and Wendy punched him in the face, chipping his tooth. While Robbie remembers, Wendy managed to forget. Afterwards, the two have been friends for some period of time and like to hang out. Despite his typically careless attitude toward other people, he expresses some concern for Wendy, though this is highly limited. Robbie has feelings for Wendy and managed to maintain a short-lived relationship with her, though this fizzled out after a few weeks, due to his arrogance, negligence and dishonesty. Robbie desperately tries to win Wendy back, but is unsuccessful (Wendy's exasperated reaction suggests he's made many attempts).
Robbie enjoys venturing off to spend time with his rowdy friends, particularly bonding in miscellaneous antics with his fellow males. Their visits to one another are frequent, and their activities are not always in compliance with the rules.
- The stitched heart logo on his jacket appears in the opening song "Gravity Falls theme song" on a photo of a page of the journal that has to be freeze framed to see along with other symbols supposedly associated with other characters.
- Robbie's band is called Robbie V. and The Tombstones.
- Robbie was in the list of unhappy suspects in "Headhunters."
- Similar "Explosion Muffins" to the one that Robbie spray painted on the water tower appear throughout the show in various backgrounds, most noticeably in the enclosure around the water tower.
- His last name starts with a V as revealed in "Fight Fighters."
- In "The Inconveniencing" when the group is attacked by ghosts, it seems that Robbie slips away from the chaos and returns later untouched. Unlike the rest of the teenagers (excluding Wendy) who were trapped in either hot dog displays, cereal boxes, television sets, or video games, nothing happens to him.
