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 where they usually aid in their maintenance and upkeep.

''Super Mario Galaxy
Gearmos make their first appearance in Super Mario Galaxy where most of them inhabit the Toy Time Galaxy. However they can be also found in the Buoy Base Galaxy, the Battlerock Galaxy, the Dreadnought Galaxy, the Grand Finale Galaxy and the Comet Observatory.

In the Toy Time Galaxy, Gearmos appear throughout working the various objects in the galaxy and helping Mario on his way through. They appear as helpful NPCs in the Buoy Base Galaxy and give Mario advice on how to reach the top of the tower. One Gearmo holding a metal stick with a magnet attached to the end of it appears in the Battlerock Galaxy and another appears in the Dreadnought Galaxy. These Gearmos are in charge of keeping the ammo depots clean. They ask Mario to help clean up the mess by throwing Bob-ombs at the garbage. If Mario does this for them, each will give him one Power Star in return, making two power stars if he does both missions. It is possible that both of these Gearmos are the same character as they are both green.

Another green Gearmo appears controlling the Engine Room of the Comet Observatory when Mario gets to that point in the story.

Gearmos also appear in the Grand Finale Galaxy where they tell Mario not to litter.

''Super Mario Galaxy 2
Gearmos return in the sequel, Super Mario Galaxy 2 once again with the purpose of maintaining the various galaxies they appear in. The main galaxy they appear in is the Chompworks Galaxy where they are responsible for breaking open Chain Chomp Heads.

Similar to the missions with the Bob-ombs in the original, two Gearmos with magnet sticks appear once again in the Rightside Down Galaxy and the Upside Dizzy Galaxy but this time they give Mario a Fire Flower and ask Fire Mario to burn up all the crates in twenty seconds or less in the Crate Burning mini-game.

Later on two Gearmos appear in the Tall Trunk Galaxy's Prankster Comet mission. One at the top of the slide claims to have lost 140 Purple Coins and asks Mario to get them for him. He tells them that her buddy at the bottom will give him a prize if he does. And, true to her word, the Gearmo at the bottom of the slide will give Mario a Power Star if he got at least 100 Purple Coins. A green Gearmo also appears in Rolling Coaster Galaxy's Prankster Comet, giving Mario the star if he succeeds in getting the 100 Purple Coins.

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.This is similar to the garbage challenge from the prequel, with the Gearmos all being green.

In this game when hit with Star Bits their heads spin around.

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 portmanteau of the name Guillermo and the word gear.
 * 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, and they talk in a North Korean accent in the Korean version.
