Dominic is a bartender at the Pixel Palace. He hears a lot of strange stories from video game characters.
He makes a brief apperance at the end of The Nostalgia Critic's review of Captain N after The Critic wonders if any of the video game characters in the show will appear on Video Game Confessions. Dominic assures The Critic that their story involves Mother Brain's genatalia.
Dominic is seen in Part 5 of Kickassia as one of the cameos who say "I believe in Santa Christ" after The Nostalgia Critic shot him to death.
Dominic appeared in an April Fools video made by Last Angry Geek entitled Video Game Confession Confessions.
Dominic also appears in the review of The Shining Miniseries, as a hallucination of the increasingly insane Nostalgia Critic. Mirroring a scene from the Shining, the Critic goes into a bar inside his recording studio and the two briefly discuss the miniseries before Dominic reveals that he, and the bar itself, are imaginary, at which point it is revealed that the Critic has been drinking from a toilet.
He also makes a very brief cameo at the end of the Nostalgia Critic's review of the Blues Brothers video game after the Critic (and later, Chester A. Bum) attempt to play the game but quit in frustration. How Dominic reacts to the game is unknown, but it can be presumed that he rage-quits in a similar fashion.
Dominic wears a white shirt with a black vest and a black bowtie. According to the Nostalgia Critic, his British accent is fake.
