Reptar is a fictional character from the American animated television series Rugrats. It is a green T. rex (and sometimes appears in red-violet and lilac) with rounded, blue spike-like appendages on his back, which intentionally causes him to resemble and spoof Godzilla. Outside of Rugrats-related films, Reptar appears as a playable character in Nickelodeon Kart Racers, Nickelodeon Kart Racers 2: Grand Prix and 2021's Nickelodeon All-Star Brawl.
