|First appearance||Super Mario Galaxy 2 (2010)|
- “They call me The Chimp. Seems like you may be a worthy high-climbing rival. Take this ! We'll talk later...”
- —The Chimp, Super Mario Galaxy 2
The Chimp is a non-playable character appearing only in Super Mario Galaxy 2. He is a blue monkey that wears sunglasses and somewhat resembles an Ukiki, with yellow hair on his head in a style similar to Iggy's. The Chimp is competitive by nature and challenges Mario to beat his records in various games across different galaxies.
Mario first meets The Chimp in the Fluffy Bluff Galaxy, just after finding the Toad Brigade Captain, when he shows interest in a climbing race against Mario after watching him use the Cloud Flower. The Chimp later challenges Mario to a contest where he has to stomp on enemies and collect the coins to get 10,000 points or more with a time limit of two minutes (120 seconds).
Later, The Chimp appears in the Freezy Flake Galaxy, where he challenges Mario to a Whack-a-Mole style of game, where Mario has to get 500 points or more by hitting green Gummits and Golden Gummits while avoiding Spiky Gummits.
In Melty Monster Galaxy's secret mission, Mario needs to knock down Pinheads with the Rock Mushroom. After Mario gets 5,000 points or more, The Chimp gives him a Power Star. He next shows up in Shiverburn Galaxy and challenges Mario to another skating challenge but with 600 points as the target score. Even after, he appears in Honeyhop Galaxy, where Mario needs to defeat enemies to get points. If the player gets 10,000 points or more within the two-minute time limit, The Chimp gives Mario another Power Star.
The Chimp makes his final appearance in the Slimy Spring Galaxy, where he challenges Mario to another point challenge. This challenge is unique, however, in that it takes place mostly underwater, where Mario must shine a Green Shell's light on Snoodles and Boos. If the player can win this challenge by scoring 10,000 points or more in 180 seconds (three minutes), The Chimp gives the player a Star after requesting that Mario teach him some of his moves.

- The Chimp is the only competitor character not to directly challenge Mario to races, a trait differentiating him from his predecessors: Koopa the Quick (Super Mario 64), Il Piantissimo (Super Mario Sunshine), Cosmic Mario (Super Mario Galaxy), and the Spooky Speedster (Super Mario Galaxy).
- If the player fails a mission that The Chimp delivered to them via mail, the player will lose a life. However, if they fail a secret mission such as the ice skating challenge, they will start over.
