The Roommate is the protagonist and player avatar of My Roommate Sonic.
The Roommate is a dark-skinned male in his late 20s/early 30s. He appears dressed in plain clothing and does not exhibit any particularly noteworthy traits. However, during the events of My Roommate Sonic, the Roommate appears headless upon being sucked into the void of Sonic the Hedgehog, and soon transforms into Sonic himself.
The Roommate also appears in the Roommates DLC stage of Sonic Movie Maker. Like Sonic, the Roommate sits on the couch and constantly watches the player, however here the Roommate's face has been replaced with the Sega camcorder. This larger camcorder must be grabbed and drawn towards the player to acquire the camcorder powerup.
