Mario & Luigi: Bowser's Inside Story
Sergeant Guy, along with Corporal Paraplonk and Private Goom is first seen in Dimble Wood with a Banzai Bill Blaster. They don't have any ammo however and Bowser had to go find some.

Later on, the three of them appear at Bowser's Vault where they watch Bowser defeat the Fawful Express. After Bowser Memory M and Bowser Memory L is defeated, Bowser opens the safe containing the second Star Cure. The minions then tell Bowser there is something else in the safe and then they shut the safe with Bowser inside of it, showing that they were brainwashed by Fawful.

At the end of the game, Corporal Paraplonk, Private Goom, and Sergeant Guy apologize to Bowser about locking him in a safe and Bowser states that he will forgive them on one condition, if they help repair his castle.
