Sentrobe

Sentrobes are enemies in Skyward Sword.

Characteristics and Weaknesses
Sentrobes are round, flying robots found mainly in the Lanayru Mining Facility, only becoming active when under the effects of a Timeshift Stone. They have eyes in the center of their bodies and they fly around using a propeller attached to its inner body. They are separated vertically by their metallic shell, which opens to shoot missiles at Link. These missiles can be reflected with a Shield Attack or sword strike to damage the Sentrobe.

Sentrobe Bomb
After one of their missiles is deflected back at them, they will launch Sentrobe Bombs that follow Link around and blow up after a set time limit. Link can safely destroy them by slicing them alongside their opening, either vertically or horizontally.
