Kamen Rider ZO

   Masaru Asou was the lab assistant of geneticist Doctor Mochizuki, and was used as one of his experiments, enabling him to transform into grasshopper-like being called Kamen Rider ZO. He fled into the woods and went into a coma before Dr. Mochizuki sent him a telepathic call for help; he had created the Neo Organism, too powerful for him to control. Masaru must protect Mochizuki's child, Hiroshi, from the creatures made by the Neo Organism.

Masaru Asou / Kamen Rider ZO :
The hero of the story. He was originally an assistant to Doctor Mochizuki, the doctor conducted experiments on him, turning Asou into a grasshopper-like cyborg. He was devastated by his horrible transformation and went into hiding. Years later, he dreamt of a boy named Hiroshi, the music from a gold pocket watch, and his mission to protect Hiroshi. He awoke as ZO.

Hiroshi Mochizuki :
A young boy targeted by the Neo Organism. Hiroshi longed to be with his father, who had gone missing years ago. As a memento, Doctor Mochizuki gave Hiroshi a pocket watch that played music. Hiroshi was at first afraid of ZO, but as ZO proved he truly was a friend, Hiroshi affectionately referred to ZO as 'Rider'.

Doctor Mochizuki:
A mad scientist who turned Masaru into ZO and then created the Neo Organism. His dream was to create the "perfect lifeform", but instead it turned on him and was held captive by his creation.

Neo Organism Doras :
A pool of living fluid that relies on the very container its dwells in as its lifesupport. It took on the appearance of a deformed little boy in Hiroshi's likeness. The Neo Organism orchestrated the events in the movie, and even overpowered its creator, Doctor Mochizuki who tried to reason with it. It soon assumed the grotesque grasshopper humanoid form of Doras to find Hiroshi to force Dr. Mochizuki to complete its evolution into the "Perfect Lifeform" so it can destroy the "inferior" human race. Doras is capable of regenerating itself from severe injuries, absorbing inorganic and organic materials to upgrade itself or alter its form into an orb or a bladed projective. When Doras manage to absorbed ZO, it became a red fleshy version of itself. It then went for Hiroshi, but the music from the pocket watch managed to give ZO the strength to break free from Doras' body after Mochizuki destroyed its power source. Reverted to its normal state, Doras was finally killed.
Spider Woman: A Neo-Lifeform created by Doras, she was large 4-legged inhuman spider woman who shot strong webbing to entangle Hiroshi. She also has a set of spider legs on her back and two spider legs for a left arm. During combat with the monster, ZO snapped one of Spider Woman's legs and used it to impale and instantly kill her. She was the only Kamen Rider monster to be claymated & be a large Puppet.
Bat Man: A Neo-Lifeform created by Doras, he was a black bat-like entity. Bat Man was black, had small-but-long bat wings for ears that covered its head (unless he's flying), and an eye on each hand much like Doras. Bat Man could extend its fingers to form wings for flight. It could also disguise itself is as any human. It took on the likeness of Mochizuki to trick Hiroshi. Bat Man took the boy to its master's hideout. ZO killed Bat Man easily by impaling his fist into the monster's stomach.
Bat Man and Spider Woman are not to be confused with DC Comics hero Batman and Marvel Comics heroine Spider-Woman.

Kamen Rider Den-O

   Ryotaro Nogami is a young man with a lot of bad luck. One day, he finds a strange pass and things got stranger from a mysterious girl and a large time-traveling train to being possessed by an entity called an Imagin, beings from an alternate future whose kind are attempting to change the past. Though slightly confused about the nature of the crisis, Ryotaro, along with the aid of the hot-headed Imagin, dubbed Momotaros, becomes Kamen Rider Den-O, traveling to different times on the DenLiner to battle the evil Imagin to prevent them from altering the past to affect the present and future. During his adventure, Ryotaro is joined by other Imagin who aid him as well; the womanizing Urataros, the herculean (and narcoleptic) Kintaros, and the childish yet powerful Ryutaros. He later meets the mysterious Yuto Sakurai and his bumbling Imagin partner Deneb. Yuto is not only Kamen Rider Zeronos but is the younger incarnation of Ryotaro's older sister Airi's fiance, Sakurai, who mysteriously disappeared and is tied to the mysteries revolving the Imagin and the Junction Point.

Singularity Point :
Some of the humans in Kamen Rider Den-O are called a "Singularity Point" . The primary ability of Singularity Points is that they are able to exist outside of time itself, such that changes in their past timeline will not alter their current state. In some instances, Singularity Points have had their timelines destroyed by the actions of the Imagin, yet still exist in a physical form with their memories intact, unaffected by the changes. The Singularity Points revealed are Ryotaro, Hana, Kai, and the Owner of the DenLiner. These individuals also have the ability to resist the Imagin's ability to use their body as a host, even control them if powerful enough.

   Ryotaro and Yuto allow their Imagin to sometimes possess and utilize their bodies depending on circumstances. The possession makes the Imagin's personality dominant, and also causes a physiological change in the host. The change is evident in the physical structure, where the eyes and a streak of hair change color to that of the dominant color of the possessing Imagin merged with the host. The possession also allows the host to use the Imagin's fighting style while battling the evil Imagin as Kamen Riders. Ryotaro's Imagin are also capable of possessing him all at once. However, if not transformed into Climax Form, this multi-possession is incredibly unstable, leaving the Imagin unable to coordinate themselves and causing Ryotaro intense pain.

The Rider Pass ( Raida Pasu ):
The Rider Pass is a card-like pass that is used for granting access to the train known as the DenLiner. This process only works when the hour, minute, and second are the same, such as 12:12:12.

Rider Tickets ( Raida Chiketto ):
Rider Tickets are tickets that store information on Imagin. The tickets keep a record of the past date in which the Imagin has ventured and a figure of the Imagin when swiped over a person whose past has been violated by the Imagin.

   Kamen Rider Den-O uses the Den-O System, and can swipe the Rider Pass across the Terminal Buckle (Taminaru Bakkuru ) of the Den-O belt, specifically the SetTouch ( Setacchi ), to activate a transformation. He can also do this to achieve Form Switches ( Fomu Suicchi ), and while transformed to perform a Full Charge ( Furu Chaji , finishing attack). Up to four Imagin can be summoned by using the Rider Pass, and each allows for Den-O to change into a specific form. The red button allows for Momotaros and Sword Form. The blue button allows for Urataros and Rod Form. The yellow button allows for Kintaros and Ax Form. The purple button allows for Ryutaros and Gun Form. It is shown that Imagin that are used for the form changes temporarily take over a hosts' personality. With the Keitaros cellphone, all four Imagin can be summoned for Den-O to assume Climax Form. Den-O's Liner Form is accessed by inserting the Rider Pass into the designated slot in the DenKamen Sword. Another form from the Swan Imagin Sieg, Wing Form, is accessed by using the Wing Buckle, but Sieg's place in time prevents the normal use of this form.

   Kamen Rider Zeronos uses the Up Set ( Apusetto ) system that functions by sliding a Zeronos Card ( Zeronosu Kado ) into the Zeronos Belt ( Zeronosu Beruto ), allowing him to Form Change ( Fomu Chenji ) into either of his two forms. When the Zeronos Belt is turned into the green position, the Zeronos Card is inserted with the green side facing front, and Zeronos becomes Altair Form. When it is turned into the yellow position, the Zeronos Card is inserted with the yellow side facing front, and Zeronos becomes Vega Form, which is powered by Deneb. An alternate version of the Zeronos Card replaces the green side with a red side. When the first of these cards is used, the red side turns Altair Form into Zero Form, rusting its normal appearance. The transformation leaves Zeronos unable to assume Altair or Vega Form afterwards.

   Kamen Rider Gaoh uses the Rider Pass and SetTouch system, just like Den-O, but uses a Golden Master Pass stolen from the Denliner's Owner that allows time-travel to the distant past.
