A Moto is a creature native to SR388 that is found in Metroid II: Return of Samus and Metroid Fusion. They have a mask-like structure with horns at the top covering their faces. In Metroid II, their Artificial Intelligence is to walk to the right a set amount and then to walk to the left the same amount. Their backside is most vulnerable to attack. In Metroid Fusion they were infected and/or mimicked by X like the majority of the creatures on-board the BSL Station. These Moto-X have a more menacing look to their facial structure. If it sees Samus, it will charge at her. Shooting enough at its backside or shooting a Missile or Charge Beam shot anywhere on its body will kill it.
In Samus Returns they charge in a straight line towards Samus, which can be deflected by parrying it with Melee Counter. This will stun the Moto with its backside facing Samus, allowing Samus to attack its vulnerable backside. While Melee Counters are the best way to deal with them, Samus can also focus on attacking its backside like in past games. Like most common enemies, Samus can freeze it with the Ice Beam and shatter the frozen Moto with a Missile or Melee Counter. However it can only be frozen if Samus hits its backside.
- The Helmasaur and Helmasaurus from the Legend of Zelda series closely resemble the Moto in appearance. In The Legend of Zelda: Majora's Mask there is an enemy called a Hiploop, with a mask resembling that of the Motos in Fusion. They also have the same attack pattern. The mask can be removed by an explosion, or by using the Hookshot.
- The Motos have a body structure quite similar to the Baby Sheegoths', Sheegoths', the Grenchlers', the Grapple Guardian's and Gigafraugs' seen in later Metroid games. It is unknown whether or not the Moto inspired the latter creatures' design.
- In Metroid Fusion, when Samus returns to the main area of Sector 1 after beating Neo-Ridley, every Moto-X has diappeared. This could be attributable to the Omega Metroid consuming the X, as discarded shells can be found near areas where Motos were early in the game.
