Biography
After Jordan Midgley (Rose Orphnoch) was decapitated by Nathan Yap's Kamen Rider Phi Blaster Mode, his head is rolling about when Leo picks it up. Jordan asks him to bring him back to the Smart Brain headquarters, & to recover Delta’s belt at the same time: They’ll be using it to make the “Emperor’s Belts”. Leo says that he’ll do so on the condition that he gets one of the belts. And so, Jordan promises Leo the belt of the sky: the Psi Driver.

Leo is given the Psi Gear by the Smart Brain corporation, allowing him to transform into Kamen Rider Psi. As Psi, he is under the personal supervision of Jordan Midgley. It is not stated in the film which Orphnoch Leo is; although he does the use the Orphnoch ability to turn his finger into a tentacle to siphon Cameron's Orphnoch DNA after defeating him. Leo used the gear a total of 4 times throughout the series finale. Despite his more advanced Rider gear, the more experienced Phi performed the Phi Edge Sparkle Cut through the Psi Gear itself, into Leo's stomach & straight through his spine, destroying the Gear & killing Leo, reducing him to dust.
