Sergeant Guy

"Get it together, Private Goomp! Let's scout this area, at least."

- Sergeant Guy

Sergeant Guy is a Green Shy Guy that carries a silver pipe and (for the first time ever for a Shy Guy) Magikoopa's wand on his back. He is a minion of Bowser in Mario & Luigi: Bowser's Inside Story. He is first seen with Corporal Paraplonk and Private Goomp attempting to take Bowser's Castle back from Fawful with a Banzai Bill Blaster. However, the minions have no ammo and Bowser is forced to go inside and get some ammo. Once Bowser obtains the Banzai Bill, the three minions fire it into the castle.

When Bowser turns into Giant Bowser, he applauds when Bowser inflicts damage to Bowser's Castle as Corporal Paraplonk teaches Bowser how to battle.

Later on, in the Treasure Chamber in Bowser's Castle, Sergeant Guy and his companions watch Bowser defeat the Fawful Express and once Bowser opens the safe, Sergeant Guy and the other minions push Bowser into the safe, stating that Fawful was going to pay good money for Bowser's head.

Sergeant Guy was seen after the closing credits, where he and the other minions apologize for their treason, and ask Bowser if they could rejoin the Koopa Troop. Bowser forgives them on one condition: they have to help with castle repairs.

In Mario & Luigi: Dream Team it is revealed that Sergeant Guy was promoted along with his associates to Bowser's Royal Guard. He travels with Bowser to P'illo Island to find Princess Peach. Sergeant Guy also helps Kamek disguise as Princess Peach forming a lower section of the disguise. It is also shown that he and his associates dream of bossing around Kamek & Bowser one day.

Sergeant Guy is also fought in this installment as part of a Boss Battle. It is revealed that his magic wand allows him to slightly heal fallen comrades and make others look like him to confuse the Bros. It is also shown that Sergeant Guy has great strength as a combo attack involving the 3 requires him to chase Mario while carrying a very large Bob-bomb & that he also moves the giant Banzai Bill Cannon out of the way. The silver pipe is not used. He also attacks Private Goomp when he reveals the secret to beating them.

After being defeated, Kamek demotes them to janitors and sends them back to the castle.
