"I'm a dinosaur." -Dino Rob
Dinosaur Rob (or Dino Rob for short) is an altered character of Robert Walker, aka The Other Guy. Rob wears a dinosaur mask for this character.
Dino Rob first appeared in the My Pet Monster review. In the film, Melaine walks into her brother Max's room to discover that Max has turned into a monster while Max acts perfectly calm about it (he's reading a comic book). Feeling confused about this scene, Critic goes to ask Rob what's with that scene. As Critic walks into Rob's room, he notices that Rob's head is now a dinosaur head (Like Max in the movie, Rob is reading a comic book. He is reading The Far Side by Gary Larson). Critic asks Rob what happened to him, only for Rob to simply respond with, "I'm a dinosaur."
Since the review for My Pet Monster, Dino Rob has made appearances in only a few episodes. He appeared the following week for the Nostalgia Critic's first Commercials review. He has also appeared at the end of The Lost World: Jurassic Park review. He is at the end of the Scooby-Doo review, where he is playing cards with 80's Dan and The Ghost of Christmas Future until the Critic walks in the room. He also makes a small appearance in the opening of Jurassic Park 3 review, and portrayed the Indominus Rex in the Jurassic World review. He also had a cameo in the Star Wars: The Force Awakens review.
