In the Wii version of the game, the Gears are obtained as power-ups during levels, in specific places. Obtaining one will automatically bring Rodea to his most powerful state, while if he takes damage and reverts to his weakest state, the Gear will disappear.
In the Wii U/3DS version, once a Gear is obtained, it is permanently available and the player can switch from one Gear to another (or none) at any time. Gears can be upgraded to have better performances or additional functions.
Machine Gun Gear Edit
Shooting will decrease a gauge (Gear energy), and when the gauge is empty, the Machine Gun Gear will no longer shoot. Gear energy regenerates over time when not shooting.
In the Wii version, the pointer determines what the Machine Gun Gear is aiming at. In the Wii U/3DS version, it shoots in Rodea's direction, but the bullets then move towards the nearest enemy.
Shooting with the Machine Gun Gear is the only way to destroy spiked-ball bombs or to use the Octopus enemies to move up.
Slide Gear Edit
If Rodea touches a slide panel when the Slide Gear is equipped, he will automatically slide at high speed in the panel's direction. While sliding, he can pass through electric walls. Rodea can also slide by boosting into the ground or a wall (in the Wii U/3DS version, this ability has to be acquired by upgrading).
Rodea will stop sliding if he runs out of Gear energy, which is drained by sliding, but is automatically refilled when touching a slide panel.
Lock-on Gear Edit
Enemies or items can be targeted during a limited time (during which the Gear energy will decrease), then Rodea will dash and attack every target one by one. He can't be stopped during that time.
In the Wii version, Rodea will sometimes encounter several switches that he must hit in close succession to proceed. Using the Lock-on Gear is the only way to do so.
