In "Scary-oke," Agent Powers and his partner both arrive at the Mystery Shack to investigate reports of mysterious activity in Gravity Falls, and begin an inspection of the shack's gift shop. During their visit, Powers discloses to Dipper their ongoing investigation of a paranormal case that he suspects is deeply rooted with the town, which entices Dipper to help with their research. Powers gives him a business card that Stan quickly confiscates, eventually convincing the agents that the paranormal aspects of the town are mere legends to drum up business.
Later that night, Dipper manages to steal the card from Stan, arranging to meet Powers and Trigger in the woods where he reveals to them Journal 3. Unimpressed, Powers prepares to leave, however he is dragged off by a horde of zombies that Dipper has conjured with the journal. During the end credits, the agents emerge, having survived the encounter, and Powers states Gravity Falls is indeed the missing link in their paranormal case, prompting him to "bring in the big guns."
In "Not What He Seems," he assists in arresting Stan Pines, and then proceeds to interrogate him. However, after a gravitational anomaly, Stan escapes, tricking Powers into thinking he's leaving town in a taxi. Powers leads his men in chasing after the taxi, leaving Stan free to return to the Mystery Shack.
In "A Tale of Two Stans," Powers, alongside Trigger and some federal agents, arrive at the destroyed mystery shack to resume the investigation just as Stan finishes telling his and Ford's backstory. However, just before they can go in and find out about the lab, a modified blast from the memory erasing gun causes him and the rest of the agents to lose their memory of the events, and be driven off the case by Ford.
Agent Powers is a black-haired man, with a dark grey mustache, and a headpiece in his ear. He has a mole above the right side of his mustache. He appears to be wearing a white shirt with a folded collar and a black tie. On an upper layer he has a black suit with a small American flag pin on the left side.
- Agent Powers bears a strong resemblance to former FBI agent and Watergate conspirator G. Gordon Liddy, who was at one time notorious for his intense personality (he was a competitor on Fear Factor at the age of 75 and once ate a rat to demonstrate his strength of will).
- His name and occupation may be a reference to the fictional spy character Austin Powers.
- He and Trigger's name is a play on the term "power trigger."
- He slightly resembles Ron Swanson, a character also played by Nick Offerman, on Parks and Recreation. Coincidentally, he works for the Federal Government, which Ron says he'd never do in the season 6 finale of Parks and Recreation (however, he does accept a job with the national parks service in the series finale).
- Despite saying that he used Trigger as a human shield, in "Scary-oke" he and Trigger were grabbed by two pairs of zombies then dragged off screen. He could have meant after they were dragged off, however.
- Many of the motives and mannerisms of Powers and Trigger are pulled directly from Agents J & K of the MiB franchise, including Powers' lack of a sense of humour.
