Another Kikai

Another Kikai is a unique Another Rider whose Ridewatch manifested in the form of an insect-like creature and an antagonist in episodes 23 and 24 of Kamen Rider Zi-O.

History
Unlike other Another Riders, Another Kikai was not created by the Time Jackers and instead took the form of a stick insect-like creature before using a tree to construct a body for itself. Whenever it was destroyed by the Riders, it would simply use another tree as its host. After Another Kikai defeated by the Riders, it taken by Sworz who forced it on Uhr so he could harness the power of Kikai.

Trivia

 * Another Kikai's would motif is a pun on the fact that the character for "machine" (機械 Kikai) also contains the kanji for "wood" (木 Ki). It could also be based on an inversion of the original Kamen Rider Kikai's machine motif.
