The Double Drivers linked, they are used to transfer Philip's consciousness into Shotaro along with the former's inserted Gaia Memory. Their catchphrase at the start of a battle is "Now, count your sins!", which is originally used by Sokichi Narumi.

Double rides the modified Honda CBR1000RR motorcycle called the HardBoilder, using the Rotation-Interchange Base RevolGarry mobile garage to covert it into the HardTurbuler hovercraft or the HardSplasher personal water craft.
Normally, Double uses different combinations of Gaia Memories to access various combinations of powers, weapons, strengths, and weaknesses through Half Changes, switching from one form to another by switching out one or both Gaia Memories in the belt in a Memory Change.

Vowing to ensure that no one ever feels sad, Shotaro became a protégé of Futo's private investigator Sokichi Narumi after admiring his work as a child. Unlike his mentor, Shotaro was incapable of making the tough decisions most of the time due to his kindhearted nature, which is the main reason why many consider him "halfboiled".
Following Sokichi's death in the Begins Night incident, their investigation leading to Shotaro meeting Philip, Shotaro promises to continue in his mentor's stead while becoming a man worthy of wearing Sokichi's white fedora. Thus Shotaro works to stop the Dopant crime wave in Futo by providing his body as Kamen Rider Double, taking pride in the role and being called a "Kamen Rider" by the citizens.

After being rescued by Shotaro and Sokichi Narumi, the latter naming him after the fictional detective Philip Marlowe, Philip aids Shotaro to atone for being used as a puppet willingly by his captors. Normally remaining in the Detective Agency's secret hangar, reading at his spare time with a habit of becoming obsessed with a topic of interest, Philip investigates Dopant activities through his ability to access the Gaia Library and its Infinite Archive, a metaphysical realm and Akashic records in the form of white room filled with an endless number of books on an endless number of bookshelves.
While initially a logic-minded sociopath with little common sense who constantly irks all around him, Philip gradually becomes more empathic while eventually learning his former identity as a member of the Sonozaki Family. He was eventually captured and was absorbed by Wakana to restore the Museum's hold on the True Gaia Memory, later extracted by Shotaro. But the event renders Philip's body unstable to the point that should he transform into Kamen Rider Double again, he would break up into data and be completely absorbed by the planet once he cancels transformation. Saving their final transformation to save Wakana and fight Jun Kazu, Philip has Shotaro promise him that he will still fight for Futo even after he is gone. After Kazu is defeated, Philip bids his final farewell to Shotaro as he fades away once the transformation is cancelled. Before he left, Philip left Shotaro a gift containing a Lost Driver buckle and the blank book he used to bring around with him, containing a message thanking Shotaro and asking him to continue to protect Futo. However, after Wakana learns that Philip sacrificed his own physical existence to save her, she initiates her own Gaia Impact: sacrificing herself to bring back the Xtreme Memory and reconstruct Philip's physical body.

Later, after her father's death, Saeko is disillusioned until she learns of Wakana's survival and regains the Taboo Memory from Kazu after he announces that she has become the head of the Museum.

This Gold Memory, known as the Utopia Memory, allows him to become the seemingly omnipotent, with reality-bending powers that result from the Utopia Memory's ability to grant its user's wishes, mainly used to repel attacks aimed at him, and absorb the emotions of living beings to further power itself.

However, Wakana's comatose state forces Kazu to wait until her power resurfaces. In order to awaken her and reclaim Saeko, Kazu reveals himself to the Kamen Riders and assumes his Dopant form to overpower them. After discovering that Philip's emotions are tied to Wakana's powers as ClayDoll Xtreme, he decides to attack everyone close to him in order to initiate the Gaia Impact. After he is exposed as a Necro-Over, Kazu professes his love for Saeko and reluctantly kills her when she rebuffs and attacks him.

He survives, however, and comes after them, battling Kamen Rider Double CycloneJokerXtreme. The duo manage to further weaken him by overloading him with Philip's final feelings before using the Double Prism Xtreme Maximum Drive to defeat the Utopia Dopant.
