This article is about a/an Imagin in Kamen Rider Den-O.

Oct Imagin (オクトイマジン Okuto Imajin) was an evil Imagin in Kamen Rider Den-O.



Kamen Rider Den-O

His contract holder is Shōko Hazuki, who simply wants Yuto Sakurai to be brought to her, though the Imagin is frustrated that he has to bring him alive for the contract to be completed. The Oct Imagin uses ink smoke bombs to temporarily blind its opponent and possesses tentacles able to infect and control inanimate objects. He takes control of the DenBird and a nearby truck to use against Den-O. When the Oct Imagin travels back in time, he can now kill Yuto without any penalty, controlling the ZeroGasher against Zeronos.
Oct Imagin Hydra Line

Hydra-like tracks

Although destroyed by the combined efforts of Liner Form and Zero Form, a piece of his tentacle infected the AuraLiner from Liner Form's finisher, entering time and building itself into a giant hydra-like monster formed by numerous time tracks. It takes the combined firepower of all the time trains and mobilizing the KingLiner to destroy it.

More Oct Imagin later appear as part of Kai's Imagin army in the finale arc.
