- 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.
- His and Trigger's name is a play on the term "power trigger".
- He slightly resembles Ron Swanson, a character also played by Nick Offerman in 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 humor.
