|This article is about a/an Imagin in Kamen Rider Den-O.|
The Mantis Imagin (マンティスイマジン Mantisu Imajin) was a female masochist Imagin with the ability to spray a poisonous purple gas and wield twin rapiers as her weapons. Her goal was to allow a Miku Uehara from the near future to see her grandmother for the last time, as in her timeline she kept putting off celebrating her birthday with her grandmother up until her grandmother died before it could happen. Before the Mantis Imagin can complete her contract and go back in time, New Den-O defeats her.
