Masaru Aso (麻生 勝 Asō Masaru) is Kamen Rider ZO (仮面ライダーZO Kamen Raidā Zetto Ō, Masked Rider ZO), the main protagonist in the Japanese tokusatsu movie Kamen Rider ZO.

History

Masaru was originally an assistant to Doctor Mochizuki until the doctor conducted experiments on him. Horrified at being made into a grasshopper-like cyborg, Masaru went into hiding in the mountains, but fell asleep for two years until he awoke with an unconscious urge to protect "Hiroshi". Finding the boy, he fought with the monster Doras who was attacking him, transforming into Kamen Rider ZO in the process. Impaling Doras on a metal pole, he followed the boy, Hiroshi's grandfather Seikichi Mochizuki recognizing him.

He again transformed into ZO to protect Hiroshi from the Koumori Man and Kumo Woman, monsters sent after Hiroshi by Doras. He defeated the Kumo Woman, but the Koumori Man took Hiroshi to his father Doctor Mochizuki's lab. Following, he quickly defeated the Koumori Man before the Neo Organism, Mochizuki's ultimate creation, awoke, having imprisoned the Doctor for not letting it go free. ZO is defeated and absorbed by Doras, but hearing the music of Hiroshi's pocket watch distracts Doras, letting ZO break free and destroy it and the Neo Organism. He managed to rescue Hiroshi but couldn't save the Doctor. Bringing Hiroshi back to his grandfather, he rides away on his motorcycle. Kamen Rider ZO

Though he hated Mochizuki for making him a cyborg, Masaru eventually forgave him before learning the man was telepathically communicating with him.[1]

ZO and J, with Berry.

Later, ZO teamed up with Kamen Rider J. The two riders fought a gang of five revived monsters led by Shadow Moon: Sai Mutant, Cyborg Soldier Lv. 2, Agito, Garai, and Zu. Berry witnessed Shadow Moon's plot and is attacked by the mutants. Masato and his sister Ayumi stumble onto an injured Berry by chance and are chased by the revived mutant army as a result.

However, they are saved by the sudden arrival of Kamen Rider ZO on his ZO Bringer motorcycle, who thwarts off the monsters into a nearby abandoned warehouse. ZO is suddenly assisted by Kamen Rider J, who arrives into the warehouse on his J Crosser bike. The five mutants are defeated by the combined forces of the new Double Riders. The two are then challenged by Shadow Moon, who enlarges himself into giant proportions. J grows into giant size as well and fights off Shadow Moon by himself. Shadow Moon is defeated and peace returns to the day. Kamen Rider World

He arrives with the other Riders to fight Dai-Shocker's monster army, fighting Shocker Combatmen, the Butterfly Orphnoch, a Bakeneko, and the Slug Orphnoch before taking part in the All Rider Kick to destroy the Dai-Shocker Castle and Nobuhiko Tsukikage (Shadow Moon). He then became a Kamen Ride Card for Kamen Rider J as the giant Decade Complete Form to kick through to defeat King Dark. The day saved, he left with the other Riders through a dimensional rift.

ZO (Let's Go Kamen Riders)

ZO as seen in Let's Go Kamen Riders.

A mishap caused by the Greeed Ankh unintentionally altered the timeline which enabled Shocker to utilize a Cell Medal to create the Shocker Greeed which defeated the Double Riders and seemingly erased the legacy of the Kamen Riders from history. In 2011, after Kamen Rider New Den-O's attempt to repair the damage, he along with Kamen Rider OOO and M-Ankh awaited execution. However, it was revealed the Double Riders had their brainwashing removed by a Shocker scientist.

The Double Riders joined with New Den-O and OOO to fight Shocker's forces, but were eventually defeated. When the order was given to kill everyone, V3 suddenly appeared, asserting that there were more than four riders. V3 was soon followed by all the other revived riders that came after him, including ZO, as even though Rider history was changed, the people's memories haven't changed.

After the riders were united, they faced off against Shocker's Great Leader. Later, when joined by a force of extra riders, ZO and all the other riders got on their motorcycles and performed the "All Rider Break", ramming into the Rock Great Leader and defeating it once and for all.

Super Hero Taisen

14 Showa KR,9 Heisei Rider & 1 Neo-Heisei Rider(with Accel)

ZO was among the Kamen Riders caught up in the 'Super Hero Taisen' incident. He was presumably sent to the dimensional rift, under the pretense of being defeated, by Captain Marvelous while he was apparently hunting the Riders. When his and Tsukasa's ruse was revealed, ZO and the other Riders appeared through the dimensional wall. ZO then fought alongside all the other Kamen Riders and Super Sentai against Dai-Shocker and Dai-Zangyack's Shocker-Zangyack Alliance. Kamen Rider × Super Sentai: Super Hero Taisen

Kamen Rider Taisen

As one of the 15 Showa Riders, ZO fought in the battle against the 15 Heisei Riders in Zawame City. At some point during the fighting he was defeated by a Heisei Rider, turning into a Lockseed.

ZO was later released with all the other sealed Riders by Kamen Riders Gaim and ZX. United, all 30 Kamen Riders teamed-up to take down the revived Badan Empire.

After Badan was defeated, ZO fought with the Showa Riders in a final showdown against the Heisei Riders. ZO took on Agito, striking each other with their Rider Kicks and falling to the ground after their power collided. The battle was ended when Rider 1 and Gaim reconciled on the differences of the two sides of Kamen Riders. Heisei Rider vs. Showa Rider: Kamen Rider Taisen feat. Super Sentai

Super Hero Taisen GP Kamen Rider 3Icon-crosswiki

Due to the timeline alteration caused by Shocker, ZO became one of the brainwashed Riders in that timeline, donning the name of Shocker Rider ZO. Later on, he aided the other Riders to combat Shocker after he, and the other Riders, were released from being brainwashed by the revived Double Riders.

ZO also rides on the Z-Bringer (Zブリンガー Zetto Buringā), built by Dr. Mochizuki. Though resembling a regular motorcycle, the Z-Bringer changes along with ZO with ability to reach speeds up to 1300 km/h and resist heat up to 1000 degrees. ZO can use the Z-Bringer to execute the Z-Bringer Attack (Zブリンガーアタック Zetto Buringā Attacku) Rider Break.

Legend Rider Devices

Kamen Ride ZO

Kamen Ride ZO

Kamen Ride ZO (カメンライドZO Kamen Raido Zetto Ō) is the Kamen Ride Card which contains the power of Kamen Rider ZO. In All Riders vs. Dai-Shocker, Decade Complete Form Jumbo Formation performed the Final Dimension Kick, a variation of the Dimension Kick, transforming the Shōwa Riders, including ZO, and Heisei Riders into Kamen Ride cards for Decade to travel through as opposed to Final Attack Ride cards before hitting the target.

In theory, this card would allow Kamen Rider Decade to transform into ZO.

ZO LockSeed

ZO Lockseed

Kamen Rider ZO Lockseed (仮面ライダーZOロックシード Kamen Raidā Zetto Ō Rokkushīdo): A Lockseed bearing the likeness of Kamen Rider ZO, created when ZO was defeated in the battle between the Showa Riders and Heisei Riders.

When inserted into a Sengoku Driver or when channeled through the Showa Rider Lockseed, it would allow an Armored Rider to assume ZO Arms (ZOアームズ Zetto Ō Āmuzu). It is styled for Zangetsu and Mars in the toyline.

Let's Go Kamen Rider net movies

  • In the 4th net movie Listen Quietly! The Tragedy of the 20th Anniversary Rider!, ZO was doing a speech to commemorate the film and the franchises 40th anniversary. The speech quickly became a rant about how his film came out in 1993 rather than 1991 and yet is considered a 20th anniversary production when it was the 22nd year of the franchise, how people confuse him with Kamen Rider J despite having a different look, the pronunciation and meaning of his name, how his enemy Doras was the villain of Movie War 2010 and the fact he didn't get to fight him. He then screams that he demands to know who is responsible for his misfortune but then he is dragged off the stage by 1, 2, OOO and Den-O.

Notes

UpgradeZO
  • Keita Amemiya had designed ZO's upgraded form. In this form ZO was wearing a red scarf, and his limbs and belt becomes silver. But it has never been adopted because the other producers changed their mind.


FakeZOSuit
  • In the earliest trailer which was titled "Masked -Rider-", ZO's suit looks completely different from the film version. Many years later, Keita Amemiya finally confirmed it is actually Kamen Rider Black's suit since at that time they didn't have a final design.[2]
