Captain Goomba is the main protagonist of the Minion Quest: The Search for Bowser story mode from Mario & Luigi: Superstar Saga + Bowser's Minions, and the Mario Bros' first enemy in the original game. The mode takes place concurrent with the main story of Superstar Saga, after the Koopa Cruiser crashes into Stardust Fields. His goal throughout the story is to travel around the Beanbean Kingdom to reunite and rally all members of Bowser's army, and ultimately, reunite with their leader, Bowser, and multiple times, this plays a direct role in the Mario Bros' adventure. While Captain Goomba serves as the main character of the story, other captains can be unlocked; this includes Captain Shy Guy, Captain Boo, and Captain Koopa Troopa. Just like almost all of the minions, Captain Goomba has a deep hatred of the Mario Bros, being the first enemy they fought in the original game, but he still maintains a grudging respect towards them, as even he thinks that "Bowser's" orders to destroy Mario are too much, and later on, when the squad is in the Mechawful factory, he counts on them to defeat the fake Bowser so he and his squad can reunite with Bowser, as he knows from Fawful and Cackletta that the Mario Bros. are going to confront them soon.
After the Mario Bros. defeat him and Private Goomp in the first battle of the game, he starts out in a barrel, swearing with his Goomba comrade that they'll have a bigger role. However, after Fawful's attack on the Koopa Cruiser, he was separated from his fellow minions and grew worried. He eventually heard a crash as well as Bowser being flung through the sky upon emerging from Hoohoo Mountain (presumably, this occurred after Mario and Luigi's fight against Tolstar due to the timing). He eventually ends up inadvertently picking a fight with a Beanie. After recongregating with his allies (leading to an "awkward hug" by pouncing on one of them), he is then promoted to captain of the unit (although it is heavily implied that they simply stuck him in the position because the others were unwilling to take up the mantle), which he accepts, although he humorously ends up not understanding the position or the flag. He then leads them to his first battle and recruiting more soldiers (and being told he had an aura) before charging off to save Bowser. However, he ends up running into a wall. Over the course of the adventure, however, he starts to prove himself a truly great and effective leader, with his fellow comrade Captain Shy Guy remarking at one point that he reminds him of Bowser, and his soldiers ultimately gain a lot of respect for the ambitious young Goomba and look up to him.
After Cackletta possesses Bowser to form Bowletta, Captain Goomba grows suspicious at "Bowser's" unusually harsh language, telling them to "destroy" Mario, and his suspicions are confirmed by a Lakitu spying on her. In the end, it is revealed that him landing on Bowser's head was what gave Bowser his amnesia in the first place, and Bowser angrily chases him. Afterwards, the narration states that he was stripped of his command and resumed his old name, Goomba, although his former minions never forget his leadership.
