Kamen Rider Delta

Kamen Rider Delta (仮面ライダーデルタ, Kamen Rider Deruta, Masked Rider Delta) is a suit of high-tech armor seen in Kamen Rider 555.


Multiple humans and Orphnochs have worn the Delta Belt and successfully transformed into Kamen Rider Delta (even just briefly) at one time or another during the TV series. Three Ryūsei School students and other users used the system before the following:

In Paradise Lost, Shuji Mihara is conspicuously absent without explanation (At the making of the movie, Mihara had not yet made his debut). However in the S.I.C. Hero Saga Kamen Rider 555: Lost World   Episode 3: Delta, it is explained that Masato Kusaka, believing Mihara had sent Mari flowers, allowed and ensured his death from contact with the Rose Orphnoch's Blue Roses, which would either transform victims into another Orphnoch or kill them. The other Ryūsei School students, including Rina and Saya, were attacked by humans who had been turned into Orphnochs. The Delta Gear was destroyed, but it was used by Murakami to make the two Emperor's Belt: Psyga and Orga.

Delta Gear History

The Delta Gear was the first set of Kamen Rider Gear developed by the Smart Brain Corporation to protect the Orphnoch King. It never moved past the prototype stage. The Suit had more power and speed than the Faiz and Kaixa Gears, but is significantly less functional - it is severely lacking in weaponry and modularity, and provides no strategic enhancements past the initial speed and power increase. It was also the only gear that allows humans to utilize without killing them in the process, however, there were potential side-effects.

Early appearances of the Delta Gear are regarded with something akin to horror, as the mere presence of the Delta Gear's wearer inspired fear and dread in Orphnochs as well as other Kamen Riders. One notable detail is that Orphnochs killed by Delta die with a red flame explosion as opposed to the usual blue flames; the reason for this is left unclear.

The Delta Gear was coveted and transferred around by several members of the Ryūsei School until it was taken by Kitazaki (Dragon Orphnoch) of Lucky Clover until he grew bored of being Delta and abandoned the Belt. It was once again tossed around from person to person until Shūji Mihara was appointed its primary user.

Some side effects include the user becoming mentally unstable and developing an addiction to using the Gear, as well as developing minor Orphnoch-like powers. Those with strong enough will or just dislike fighting in general, can use the Delta Gear without the mentioned side effects (for example, Saya Kimura of Ryuseiji was able to use it properly; however, it may have well contributed to her illness which caused her inability to fend off Aki Sawada/Spider Orphnoch when he killed her). By the end of the series, the Delta Gear was still intact; it is assumed Mihara is still carrying it.

Kamen Rider Delta's finishing attack is called the Lucifer's Hammer (ルシファーのハンマー Rushifā no hanmā) this finisher is executed when the Photon Stream is shot from the Delta Mover and when it connects, it stuns the adversary, in which the Rider executes either a bicycle kick or a front dropkick into the stream, causing the enemies' destruction.

The Delta Armor has several key features in its design. Unlike the Gear, the armor only exists after the wearer transforms.

  • Photon Blood - A glowing substance that provides all of the Rider’s powers and generates all of the physical features of the armor. The Photon Blood is generated from the Delta Driver.
  • Sol Foam/Metal - Soft parts of the armor are made of Sol Foam, and the hard parts are made of Sol Metal 228. This substance is generated by the Delta Driver to form complex machinery that is powered by Photon Blood. If the Foam or Metal are damaged, the armor switches off and resets itself.
  • Black Shell Met (ブラックシェルメット Burakku Sheru Metto) - The head. It is a reinforced helmet developed by Smart Brain, and has a thin shell layer made out of Sol Metal (ソルメタル Soru Metaru), a super-metal with a hardness close to that of a diamond. An impact absorption bag is installed inside.
    • Receiver Slate (レシーバー・スレート Reshībā Surēto) - The large triangle on the forehead of the Black Shell Met. It receives the Demon's Idea from the Demon's Slate on the chest armor, and is directly connected to its wearer's brain by a capillary cable which has a diameter of 0.52 nanometers.
    • Ultimate Finder (アルティメットファインダー Arutimetto Faindā) - The large eyepieces of the Rider give them 180 degrees anterior field of view. They also allow the wearer to have night vision and X-ray vision.
    • Global Feeler: The antenna on the Rider’s head can be used to communicate with the Smart Brain Satellite and the Smart Brain computer network.
  • Shoulder Sword (ショルダースウォード Shorudā Suōdo) - Delta's shoulder armor. It is made out of Sol Metal 228, a super-metal developed by Smart Brain that has a hardness close to that of a diamond. When used in shoulder tackles, it concentrates Delta's Photon Blood, making it a powerful weapon.
  • Demon's Slate (デモンズ・スレート) - A strengthening device located directly on the triangle part of the chest plate. It forcibly raises the frequency of Delta's gamma brain waves to increase his fighting instincts. However, it can change the wearer's personality and cause mental breakdown if used for too long.
  • Delta Lung (デルタラング Deruta Rangu) - The triangular chest armor found under the Demon's Slate. It is made out of Sol Metal: a super-metal developed by Smart Brain which has a hardness close to that of a diamond. It disperses the force of any sustained impact in a thousandth of a second, and is durable enough to directly take the firepower of a tank. In addition to this extreme durability, the Delta Lung also features a built-in oxygen tank that can supply its user with oxygen for up to 3 hours.
  • Bright Streams (ブライトストリーム Buraito Sutorīmu) - The white lines running through Delta's Armor, which carry white photon blood that has the same power output as Faiz's Axel Form. They feature special maneuvers that are not seen on Kamen Rider Faiz or Kamen Rider Kaixa's Photon Streams, dividing into a fork-like formation at key points on the Sol Foam suit. This creates a reverse bottleneck effect, increasing the flow of the Photon Blood.
  • Bigger Stream Pattern (ビガーストリームパターン Bigā Sutorīmu Patān) - Delta's unique mechanism which increases the amount of energy flow by dividing the Bright Streams into 3 points at the arms and the legs.
  • Photon Terminal (フォトンターミナル Foton Tāminaru) - Where the Photon Streams connect with the gauntlets and greaves. It is twice as strong as Kamen Rider Faiz and Kamen Rider Kaixa's. It has three terminals connected that emit a lot of energy, so this equipment has resistors along the stream so that the suit itself does not self-destruct, and it supplies power to the whole body in a stable manner. There is another Photon Terminal located on the back.
    • Power Anklets (パワーアンクレット Pawā Ankuretto) - The ankle armor, which has the role of protecting the wearer from the force generated from powerful kicks.
    • Flex Bellows (フレックスベロウズ Furekkusu Berouzu) - They surround the calves as a shock absorbing air bag to protect the legs from the intense impact when kicking or from falling.
    • Photon Muzzle (フォトンマズル) - Control terminals on the soles of Delta's boots that release concentrated Photon Blood when performing the Lucifer's Hammer. The opening is in the shape of the letter "Δ".

Delta Ridewatch (デルタライドウォッチ, Deruta Raidowotchi)[2]: Based on Kamen Rider Delta, this Ridewatch would provide access to the DeltaArmor. It is dated 2003.


  • It is theorized that unlike the Faiz and Kaixa equipment, the Delta Gear can be worn and used by anybody, regardless of whether or not they are an Orphenoch or implanted with Orphenoch DNA. However, due to the fact Delta was never seen used by a normal Human, this has never been confirmed.
  • The Delta Driver bears a striking resemblance to the Access Lock SIcon-crosswiki.png from Tokusou ExceedraftIcon-crosswiki.png. They are both black-and-silver handle-like transformation devices, with a spring-loaded part and an antenna.
  • There were two props made for the Delta Gear: One which was used as a part of the suit and the Other which is stored in the suitcase. The DX version of the Delta Gear is based on the prop used out-of-suit and is smaller as a result. The CSM Version is based on the prop used on the suit.
