Doug Shablowski

Doug "The Doppelganger" Shablowski is a character featured in Temp Check.

Description
Doug is an otter that made his first (and probably only) appearance in the episode Temp Check as the main antagonist. He just came to the city to begin working as a temp (temporary worker) for Rigby, but then started to copy Rigby's actions, appearance, and voice; later in the episode, he actually becomes Rigby, and it was very hard to tell him apart from the actual Rigby. In the climax of the episode, Doug was even briefly chosen over Rigby as the "real" Rigby; but, since the real Rigby would never give man hugs like Doug did, he is soon found out by Mordecai and gets arrested. Additionally, he apparently had been pulling this scam across the country and was a wanted criminal. He was nicer to everyone and was actually working and doing his jobs assigned to him and Benson mistook him for Rigby in a scene.

Appearance
Doug is a brown otter with black, long whiskers and a round, black nose. When he first arrived at the park, he was wearing a white, long-sleeved shirt, blue jeans with a belt, and an red and white trucker hat. To copy Rigby, he stopped wearing almost all his clothes (except for his hat).

Abilities
Doug, as his nickname implies, is able to copy a person's voice, appearance, personality, and general abilities. He began taking Rigby's form when he and Mordecai were trying to make an impression of him; later, Doug began to copy Rigby's hairstyle, gain the black circles around his eyes, and point his tail the way Rigby does. Doug then finished his transformation by becoming an exact copy of Rigby.

Doug also seems to be able to take the person's memories, or at least learn them incredibly fast. During a trivia test, he was able to correctly answer questions about Rigby.

Trivia

 * The name Doug is an anglicized form of the Scots-Irish word dubh, which means dark.
 * Doug seems to have no shame, considering the fact that he willingly took off all his clothes to emulate Rigby.
 * When you hear Doug talk, sometimes you can hear Sonic the Hedgehog's voice. This is probley due to Roger Craig Smith also voices Sonic.
