"Beginning the lookup..."

- Philip's words before entering the Gaia Library

Philip (フィリップ) is the right sided-half of Kamen Rider Double. He is a mysterious young man who works as Shotaro Hidari 's partner after he and Detective Narumi save him from an experiment conducted by the Sonozaki Family. Being an avatar to the true Gaia Memory, he has full access to the Gaia Library, which he often interfaces with to look up for information on Dopants, and has computational capabilities comparable to that of a supercomputer. He fights Dopants with Shotaro, projecting his mind into Shotaro's body to form the right half of Kamen Rider Double. Philip represents the mind of Double.

History
Four Years After The Events Of Kamen Rider Double, Double Driver no longer Functioned So Assumed The Role of Kamen Rider Cyclone.

Kamen Rider Cyclone
"Cyclone!"

- Transformation announcement

Through the power of the Cyclone Memory and the Lost Driver, Philip uses the power of the Cyclone Memory to its full potential. When the Memory is placed into the Maximum Slot, Cyclone executes a Rider Kick Maximum Drive. Along with Kamen Rider Joker, the two can execute the Double Rider Kick Maximum Drive. Philip uses this form in the Kamen Rider W novel, "The One Who Comes After Z", during which Shotaro is put out of commission due to a cold. Shroud gives Philip a Lost Driver, which he uses to become Kamen Rider Cyclone, and this is the same Driver he gives Shotaro before the final battle with Jun Kazu. In the video game, Kamen Rider: Super Climax Heroes, Kamen Rider Cyclone also appears as part of Kamen Rider Joker's Rider Arts move, performing their Double Rider Kick.
