Gearmo

"BRING IT ON! Gimme your worst!"

- Gearmo

Gearmos are robot allies that appear in Super Mario Galaxy and Super Mario Galaxy 2. They are usually seen inhabiting industrialized galaxies were they usually aid in their maintenance and upkeep.

Super Mario Galaxy
In Super Mario Galaxy, most Gearmos live in the Toy Time Galaxy. Gearmos can be also found in the Buoy Base Galaxy, the Battlerock Galaxy, the Dreadnought Galaxy, and the Grand Finale Galaxy. A green one is also controlling the Engine Room. Two Gearmos holding magnets attached to metal sticks are shown in the game. They are in charge of keeping the ammo depots in the Battlerock Galaxy and the Dreadnought Galaxy clean. They ask Mario to help them by throwing Bob-ombs at the garbage in exchange for Power Stars. It is possible that both of these Gearmos are the same character, since both are green.

Super Mario Galaxy 2
Gearmos do return in Super Mario Galaxy 2, with the same purposes as in the prequel. This time, they are workers in the Chompworks Galaxy, also making appearances in other galaxies as well. When special missions are completed in the Boulder Bowl Galaxy and Space Storm Galaxy, two Gearmos, a Gold Gearmo and a Silver Gearmo, will join Mario in his adventures on the Starship Mario, and give him a 1-up Mushroom when talked to. In addition to this, green Gearmos appears in the Rightside Down and Upside Dizzy galaxies, where they will ask Mario to destroy crates as Fire Mario in 20 seconds or less. This is similar to the garbage challenge from the prequel, with the Gearmos both being green. Two other Gearmos, a silver and red one, appear in the mission for Tall Trunk Galaxy's Prankster Comet mission. The silver one claims to have lost 140 purple coins on the slide, and says if Mario/Luigi gets at least 100, they'll get something from the other Gearmo, at the bottom of the slide. A green one also appears in Rolling Coaster Galaxy's Prankster Comet, giving Mario the star if he succeeds in getting the 100 Purple Coins.

Characteristics and Traits
Most Gearmos are irritable neat-freaks. The Gearmo with the magnet becomes furious at Mario if he does not complete the Bob-omb Challenge. Another one gets angry at him for destroying a giant weight holding down a tower, and another warns Mario not to let it catch him littering.

Gearmos have a large gear inside the back of their heads. If Mario jumps on the gear, it pops out, and falls back into place. Gearmos are capable of moving without the gear, suggesting that the gear has no real purpose. This may also indicate that Gearmos are living beings rather than robots. Further proof of this is the fact that, if the player gets zero purple coins in the Battlerock Galaxy, the Gearmo at the end will refer to herself as "this old iron lady", indicating Gearmos have separate genders, despite being iron robots.

Trivia

 * Gearmo could possibly be a pun on the name Guillermo.
 * In Japanese, Gearmos speak in Kansai-ben, a non-standard dialect commonly used in Japanese media to indicate that a speaker is humorous or witty.
