Commander Shroob

Commander Shroob is a pink Shroob with a black mustache and a whistle. He is encountered during the events of Mario & Luigi: Partners in Time. He was the commander of the Shroob occupation forces during their invasion of the Mushroom Kingdom. Commander Shroob was confronted and ultimately defeated by the four heroic defenders of the Mushroom Kingdom past and present: Mario, Luigi, Baby Mario, and Baby Luigi.

The battle between the four Mario Bros. and Commander Shroob took place on Star Hill. During the confrontation, Commander Shroob would command his loyal Support Shroobs from behind the scenes, allowing his soldiers to fight the heroes while avoiding personal injury. However, the Mario Bros. could send the massive Shroob-omb rolling backwards. The bomb would then explode, knocking Commander Shroob into the battlefield.

However, even when forced to battle, Commander Shroob's primary attack was calling his Support Shroobs into the battlefield and launching them at the Mario Bros. Some would be sent twirling on the ground while others were sent flying in the air. While in the air, if a Support Shroob was pointing up, the Shroob would fall on top of Mario; if pointing downwards, the Support Shroob would fall on Luigi. The Support Shroobs could be blocked with swings from the Baby Mario's Hammers. Occasionally, Commander Shroob would approach the Mario Bros. and shoot them with his ray gun, just like a normal Shroob soldier. It was much faster than a regular shroob ray gun, however.

Eventually, armed with a Shroob-omb sign, Commander Shroob would direct three more Support Shroobs and a Shroob-omb into the battlefield to continue the fight while he goes back into hiding. As such, the Mario Bros. had to knock more Shroob-ombs backwards to send Commander Shroob back into the fray. In the end, Commander Shroob's tactics were not enough to defeat the Mario Bros.' teamwork, and the Shroob's military leader was defeated in combat.

Trivia

 * While Mario and Luigi battle the Shroobs in Mario & Luigi: Bowser's Inside Story, six Commander Shroobs can be seen frozen inside blocks of ice, which may indicate they are anything from clones to genetic-creations to even a distinct species.
