Philip Xiao Long

"I have learned everything there is to know about every student in Beacon Academy...and I can tell you with the utmost certainty that your teammate, the Faunus and former White Fang member, Blake Belladonna, did not abandon you."

- Philip Philip Xiao Long is a major character during the Volume 3 Intermission of RWBY Riders: Spirits of Legend, and one of the protagonists of Volume 4. He, alongside Yang Xiao Long, make up the Kamen Rider W. He acts as the mind of the Kamen Rider, and also doubles as Kamen Rider Cyclone, when Yang is unable to fight for whatever reason.

Like Penny Polendina, he was artificially created, and Penny was originally intended to be his partner, though Philip's unique Aura, arguably more human than the former, was not compatible with her.

Appearance
Philip has the looks of a young teenage boy, having black hair that falls to his shoulders, the majority of his bangs swept to the left and covering his left eye, and is normally found wearing a dark green-and-black striped shirt underneath a sleeveless blue coat, baggy pants with the cuffs rolled up to the calves, and leather black boots with green straps.

Personality
Philip is an emotionally stunted in person, in that he rarely ever shows emotion, likely due to his limited contact with people in general. He has learned of a few things, thanks to his meetings with Penny, and Professor Albert who taught him how to read and write when he was first created, though he generally has a blank face or expression. While he is normally uncaring of other people he does not know, he has demonstrated some compassion, evident by how he consoled Yang, who was in depression for having failed to save Albert. One major quirk is his desire to know everything; once he has found something that interests him, he will learn everything there is to know about the subject, though once he has, he will show little interest, and move on to another topic of interest.

Since he came into the lives of the Xiao Long family, Philip has shown more personality. He learned everything there was to know about the students of Beacon Academy in order to gain a better understanding of the situation, and learned all information regarding Blake Belladonna, all in order to prove to Yang that her assumptions that Blake abandoned her, just like her mother did when she was born, were false. He trusts Yang a great deal, even having taken to calling her "firecracker," which he learned from reading up on Qrow Branwen's information. This trust is also shown in their team dynamics as the Kamen Rider W, in which Philip acts as the brain, and Yang as the body.

History
Philip was designed 10 years prior to the events of the story, in an attempt to make a successor to the original Kamen Rider W. Unlike his "sister," Penny Polendina, Philip's Aura was, as Albert Rhodes put it, "natural," as opposed to artificial. Because of this, any attempts to create a RemDrive Neuro-Link between the two ended in failure, with at one point Philip was unable to access the Library, a gigantic and ever-expanding database, which supposedly has all of the information in the world inside.

Prior to the events of Volume 3, Philip was visited by Mason Melnn, who was the current Kamen Rider Zangetsu, and told him that it was almost time for him to witness to the new history that was about to be written. Philip was unaware of who Mason was, and asked what he meant by that. Mason didn't answer him, and instead gave him the Twin Rider Systems, which he claimed he would need in the future, and that when the time came, he would meet the "little dragon who rides with the Devil." Afterwards, he disappears, with his presence unknown to everyone in the facility.

Abilities
Despite being an android, Philip, like Penny Polendina, possesses the power of Aura, a power that is generated by one's soul. It has been described as more "natural" than Penny's, which has caused some complications whenever the two attempt to form the Kamen Rider W. Thanks to his Aura, any injuries he sustains will heal, and he can defend against attacks that would otherwise prove fatal, but would still feel pain.

Being the successor to the original "mind" of Kamen Rider W, his focus and intelligence are comparable to a super computer and he has access to the Library, which in turn means that he has access to any recorded knowledge on Remnant. While this does not mean that he actually knows everything, his unparalleled ability to crunch enormous amounts of information in a very short time makes him looks as though he does know everything.

Philip's Semblance, aptly named Datamine by Albert, is also quite useful in tandem with his access to the Library. He is able to hack into any and all mainframes, even heavily guarded system databanks like those found in the Schnee Dust Corporation's Archives or the Altesian Military, both of which are guarded by considerably advanced firewalls.
