Background

Feng Xue's original Kamen Rider manifestation begins with the Orca Authority. The resulting black-and-white Killer Whale armor is based on a 22nd-century children's toy, but its physical enhancement is real. Its built-in special-move effects are largely cosmetic, though Feng Xue finds that their patterns can inspire usable martial-arts techniques. 242

After Feng Xue publicly appears as Kamen Rider Orca and defeats the Sea Monk, sightings spread across Colombia and draw international attention. Organizations in several countries interpret Kamen Rider as a potential human weapon against Supernatural Tales, while Eastern Country resistance groups accelerate their own Rider-system development. 249

Feng Xue later manifests the Supernatural Tale Entry “The First Kamen Rider.” Unlike adaptations of existing named Riders, Kamen Rider Orca is an original, non-existent Rider; this makes Feng Xue the first Supernatural Tale associated with that specific identity rather than the inheritor of a corresponding Progenitor Supernatural Tale. 267 293

In the Eastern Country, Kamen Rider transformations become publicly associated with the ability to expose Supernatural Tales to ordinary people. The transformation draws attention into the world's “blind spot,” allowing bystanders focused on the Rider to perceive entities they would normally overlook. 295 296

Appearance

Kamen Rider appearances vary by system, user, and loaded transformation material. Their armor is generally full-body, combining plastic-like and metallic textures with a transformation belt as its central device. 242 268

Kamen Rider Orca

• Black-and-white armor with deep-blue chest plating. 242
• Translucent wave motifs, shoulder armor with wave elements, and striped detailing. 242
• Helmet resembles a diving orca:
  • A dorsal fin projects from the forehead.
  • Pectoral-fin shapes angle backward from the sides.
  • White orca markings form the eye areas. 242
• Can be paired with an Orca-themed motorcycle. 249 267

Abilities & Skills

Transformation

Kamen Riders transform through belts loaded with a Rider System, cards, bottles, or other compatible plugins. The transformation substantially improves the user's physical abilities and may provide form-specific finishing moves. 268

• The Knight Belt can be retrieved with a motion of reaching behind the user's back. 268
• The genuine Rider Belt has no stated transformation time limit; its duration depends on the user's stamina. 268
• Kamen Rider armor can stack with Feng Xue's other armor systems, enabling layered defensive effects. 281
• Standard Kamen Rider-type belts normally cannot stack with one another; Feng Xue later exploits his various systems to bypass this limitation. 486

Rider System

The Rider System collects energy sharing [Commonality] with its Rider and turns it into transformation plugins, currently represented by Fullbottles. 268

• Collection requires the target to be defenseless. 268
• Produced plugins can enhance belts, weapons, and motorcycles. 268
• Its [Purification] property allows Feng Xue to create a Demonic Qi Bottle and access Evil Rider. 268
• The system's principle reflects the Kamen Rider theme of “enemy and ally share the same origin”: Supernatural Tales can serve as the raw material for Rider systems. 249 299
• Feng Xue can summon Rider systems, belts, and motorcycles from Riders he knows of, including systems absent from the current world. 619

Enhanced Combat Performance

Kamen Rider transformation provides durable full-body armor and major physical reinforcement. 242 268

• Feng Xue's initial Orca form raises his physical fitness by at least three times. 242
• His martial-arts-assisted punches can exceed twenty tons of force. 242
• The genuine system supplies battlefield information directly to the user's vision, improving movement control and reducing pressure when fighting groups. 268
• Rider armor protects Feng Xue from demonic erosion so long as the armor itself remains unaffected. 268

“The First Kamen Rider” Authorities

These abilities specifically belong to Feng Xue through the “The First Kamen Rider” Entry. 267

• [Supernatural Tale Nemesis] — strengthens his role as an opponent of Supernatural Tales. 267
• [Meme Power Buff] — grants bonuses or penalties when Feng Xue performs Kamen Rider-associated actions and lines. 267
  • Declaring himself “just a passing Kamen Rider” can debuff an enemy that asks his identity. 267
• [Open Mouth, Close Eyes] — when a transformed Feng Xue takes a lethal attack, he may de-transform into the characteristic prone pose to negate that instance of damage. 267
• [Hero Arrives] — allows Feng Xue to descend into the past when a hero is needed. 267

Limitations

• Feng Xue's original 22nd-century toy Driver permits only one hour of transformation per day; unused time does not carry over. 242
• The toy Driver's flashy finishing moves do not inherently increase the power of punches or kicks. 242
• The genuine Rider Belt is less durable than the toy-based Omni-Press Drive. 268 356
• Mass-distributed Rider systems based on Gu Poison Bodies depend heavily on the user's self-observation and ability to produce specific Knowledge; users without this capacity become visually and tactically generic. 308

Equipment / Weapons / Items

• Knight Belt — summonable transformation belt that accepts a loaded Rider System. 268
• Knight Motorcycle — summonable all-terrain motorcycle; can receive system-specific functions and be used as a greatsword. 268
• Kamen Rider System — plugin-generating system with purification and collection functions. 268
• Orca-themed motorcycle — a washed-up motorcycle altered through Feng Xue's Orca Authority. 249
• Transformation cards / Fullbottles — form-specific plugins used by Riders such as Evil Rider and Demon Rider. 268 297 301

Relationships

• Feng Xue — The original Kamen Rider Orca and bearer of the “The First Kamen Rider” Entry; he distributes Rider systems to people facing Supernatural Tale attacks or imminent death. 267 308
• Hoshino Rinka / Kamen Rider Demon Rider — Receives a belt and card case from a Rider from another world, then becomes an active Rider in the Eastern Country. 301 304
• Eastern Country resistance organizations — Develop their own systems and investigate Kamen Rider technology, though their early systems are incomplete and resource-limited. 249 308
• Hundred Tales — Treat Kamen Riders as a major threat and prioritize abilities such as Face Snatching and Identity Snatching as counters. 299
• Face Snatcher / Face Stealer — Successfully steals a Rider's mask and abilities, demonstrating that Rider power can be appropriated by compatible Supernatural Tales. 297 299

• Feng Xue's original toy-based Orca form is stronger in survivability than standard Rider armor due to its environmental-damage immunity, despite its one-hour daily limit. 356
• The names “Demon Rider” and “Evil Rider” are presented as normal Eastern Country-style translations despite sounding unusual. 305
