Ryo Murasame

is the main protagonist of Birth of the 10th! Kamen Riders All Together!!. He was brainwashed and forcibly converted into a cyborg by the Badan Empire, before regaining his memories and escaping, thus becoming .
==History==
Ryo and his sister were shot down while flying in the Amazon jungle by a terrorist organization known as the Badan Empire and had both of them captured. Later, Badan kills his sister and turns Murasame into a warrior named ZX and brainwashes him; however, an accident enables him to regain his memory. Murasame decided to fight to avenge his sister. His first encounter with the past Kamen Riders is when he mistakes both Kamen Rider Super-1 and Riderman as soldiers of Badan. V3 arrived and stopped ZX, telling him that they're all enemies of Badan and want to destroy the Spacetime Rupture System. Along with Riderman and Super-1, they explain to ZX, the history and meaning of being a Kamen Rider, and, finally, he decides to join them, as the 10th Rider, Kamen Rider ZX. Later he fight and successfully defeat Eisuke Mikage (Tiger-Roid).
Afterwards, Badan's base was located, and all 10 Riders went towards it. Kurayami Taishi welcomed them and sent all of Badan's troops against the Riders. V3 faced Dokuga-Roid and his Combat-Roids again, and after a long battle managed to destroy him by throwing him onto a fallen Yamaarashi-Roid. Afterwards, V3 and Rider 2 teamed up against Large Centipede Beastman, a revived Gedon monster. however, before the battle could be finished, Kurayami Taishi attempted to use hostages to make the Riders surrender. His plan fail due to Super-1's interference and Kurayami Taishi decides to use the Spacetime Rupture System, only to destroy Badan's remaining troops. After V3's call, the ten Riders gather their power with Rider Syndrome, weakening Kurayami Taishi and allowing ZX to finish him off with his ZX Kick. After Darkness is defeated, evil energy gathers in the shape of a giant skull, The Generalissimo of Badan, bidding farewell to the Riders and laughing at them.
V3 bestows upon ZX the official name and soon all Riders part ways again to continue their battle against evil around the world. 
It's assumed that ZX was able to defeat Badan at some point before RX`s series.
===Black RX===
Kamen Rider ZX, alongside the other Nine veteran Riders, fought against the secret forces of the Crisis Empire spread throughout the world, defeating them in each country. However, Crisis' main forces, in Japan, still remained and they prepared a final offensive. Rider 1 called all Riders to a meeting in a secret facility in Arizona, to prepare for the upcoming battle, where they'd go to help Kamen Rider Black RX, the Kamen Rider that was defending Japan at the time. 
The 10 Riders split into two groups, which sparred with each other. Group 1: Riders 1, 2, V3, Riderman, and X; and Group 2: Amazon, Stronger, Skyrider, Super-1, and ZX. Before Crisis makes a public announcement regarding its invasion of Japan, the 10 Riders finally leave for the final battle. 
After Crisis' war declaration, they immediately sent Gran Zairus, which landed on Earth like a meteor, destroying an entire island. Naval Commander Bosgun moved to attack Black RX, soon receiving help from Gran Zairus, who could resist all of RX's attacks. When Bosgun is about to finish him off, Rider 1 arrives, blocking his attack and kicking him away. The 9 Riders arrive shortly afterwards, rescuing RX and quickly escaping. ZX and the others introduce themselves to Kohtaro Minami. Bosgun finds them, and meeting Kohtaro and Rider 1, proposes a duel against Black RX. However, Kohtaro's friend, Kyoko Matoba soon notices a Chap hiding behind some crates to prepare an ambush and flushes it out. As the 10 veterans fight them off, Black RX faces Bosgun in a fair match and destroys him.
Meanwhile, Gran Zairus easily rips through the Japanese defense forces and brings down the city with his unmatched power. Kohtaro decides to fight, but Riders 1 and 2 argue that even Black RX's attacks are ineffective against Gran Zairus and they need a strategy before facing it again. Kohtaro decides to fight anyway, even if he dies trying. He leaves to fight again, and ZX and the other Riders follow him. 
The 11 Riders face Gran Zairus, but even a combined Rider Punch with the power of the 11 Riders is useless against him. Gran Zairus transforms into a flaming rock, burning above 1000°C, and easily knocks out ZX and the others. In the end, Black RX becomes Biorider and manages to destroy Gran Zairus from the inside out, but seemingly explodes with it.
Afterwards, ZX and the other Riders help evacuate the city's population and start to plan defensive measures for the next battle. However, a second Rider 1 appears during their meeting. The real Rider 1 accuses the impostor and punches it, making it reveal its true form, Gynaninpo. The 10 Riders face Spirit World Demons, resurrected Crisis warriors. Unfortunately when the monsters knocked down, they quickly get up again. When the battle seems hopeless, Intelligence Staff Officer Maribaron, the one behind this attack, reveals that the monsters don't die as long as she keeps a set of golden feathers with her, but Biorider returns, alive, stealing the feathers. Rider 1 receives one of the golden feathers, and V3 holds Gynaninpo while he uses the feather to stop it. Biorider then destroys the monsters all by himself.
With Kohtaro alive, the 10 Riders decide to spread themselves to observe and take on the Crisis forces, while Black RX protects his friends. 
Wanting revenge against Black RX, a powered up General Jark, commander of the Crisis forces, gains a new form called Jark Midler, kills Sunkichi and Utako Sahara and faces V3 and Riderman while X And Amazon bring their kids to Kohtaro. Meanwhile, Crisis' forces start a human hunt. Riders 1 and 2 arrive to help Kohtaro face the Chaps' troops. Stronger, Skyrider, Super-1, and ZX soon follow. X and Amazon show up with the kids and inform Kotaro on what happened. V3 and Riderman are launched through the air, falling downtown near the combat zone where ZX, alongside the other Riders, were helping Kohtaro. Jark challenges Kohtaro to a duel, and he accepts, rejecting the help of the other Riders. Black RX ends up victorious over Jark, destroying him while the other Riders watch in amazement. 
Emperor Crisis calls Kohtaro for a personal meeting. However, Rider 1 tells Amazon to follow them, and all the other Riders go too. The emperor offers Kohtaro the chance of becoming the commander of Crisis' invasion forces, however, after Kohtaro refuses, Colonel Dasmader appears alongside a group of Chaps and attacks Kohtaro. ZX and the other Riders arrive and face the Chaps, but soon the entire cave is destroyed by the Crisis Fortress called by Dasmader. Black RX boards the fortress and destroys Dasmader, the Emperor and even Crisis itself. Meanwhile, the other Riders survive the attack and meet RX after the battle is over. Following Rider 1's words, they all decide to part ways and fight evil around the world. 
===All Riders vs. Dai-Shocker===
To stop the fusion and destruction of the worlds, Tsukasa Kadoya (Kamen Rider Decade) announced a tournament gathering all Riders to find who was the strongest. ZX participated in the tournament and fought against Kamen Rider Ryuki, though he did not make it to the final round where Decade emerged victorious. ZX and the other defeated Riders disappeared into a dimensional wall and were believed to be dead, leading Dai-Shocker to initiate its offensive.
Eventually, Decade turned against Dai-Shocker and faced its troops alone. However, a large dimensional wall appeared in the battlefield, and from it, all Riders thought to be dead reappeared. ZX marched on foot with the other Riders as #1, #2 and V3 rode in on their motorcycles. United, all the Riders proceeded to face off against Dai-Shocker's army. When Shadow Moon was thrown onto the Dai-Shocker Castle, ZX participated in the All Rider Kick, using his standard kick alongside the other Riders to destroy Shadow Moon and the Dai-Shocker castle.
Soon after, Dai-Shocker's final weapon, Kingdark, emerged from the ruins of the Dai-Shocker Castle and attacked. Decade was transformed into Final Form Ride Jumbo Decadriver and merged with Kamen Rider J summoned by Diend to face it. To help Decade, ZX, alongside the other Riders, turned into giant Kamen Ride Cards to power up the giant Decade's Final Dimension Kick, destroying Kingdark. After the battle was over, ZX and the other past Riders bid goodbye to Decade and his friends before leaving through a dimensional wall. 
===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 ZX, 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, ZX 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===
ZX 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 while he was apparently hunting the Riders. When his and Tsukasa's ruse was revealed, ZX and the other Riders appeared through the dimensional wall. ZX then fought alongside all the other Kamen Riders and against Dai-Shocker and Shocker-Zangyack Alliance. He is seen during the final battle fighting Grand Beast Rei with GoseiRed, and the Hurricangers, and later seen grabbing Zangyack Commander Daiyarl. 
===Kamen Rider Taisen===
Under the direct order of Takeshi Hongo, Ryo Murasame disguises himself as his archenemy, Kurayami Taishi, in order to investigate the Badan Empire's plan, as well as make sure Gaim is the last surviving Rider from Rider Battle and to revert all the Riders out of their Lockseed forms. All the Riders are defeated and turned into Lockseeds, leaving Gaim alone and outnumbered by the Empire. Ryo finally made his move to expose his cover to the Empire that he was spying on the Empire's plan. He transformed into ZX and helped Gaim release all of the primary Riders from their Lockseed forms to defeat Kamen Rider Fifteen and the Badan Empire once and for all.
In the conclusion, he fights Tsukasa when Takeshi reveals that their feelings toward Heisei Riders was not a lie. However, he and the other Riders stop fighting after Rider 1's defeat against Gaim, making both Rider sides settle their differences. 
======
Due to the timeline alteration caused by Shocker, ZX became one of the brainwashed Riders in that timeline, donning the name of Shocker Rider ZX. Alongside Skyrider, Super-1 and the Shocker Combatmen, ZX attacked the rebel Kamen Rider Zeronos and double agent Kamen Rider 3, bombarding the pair with his Cross Shurikens. Joined by Decade, Hibiki and Agito Burning, the Shocker Riders overwhelmed Rider 3 as he allowed Mach to escape.
The next day, following the Rider Grand Prix in which Drive emerged victorious over Rider 3, who was promptly integrated into the Great Leader of Shocker's Rider Robo form, ZX was among the Riders who attacked Drive while being caught in the crossfire as the Rider Robo joined the fray. Ultimately, the Double Riders 1 and 2 made their appearance having survived their apparent demise from within the Rider Robo, and broke Shocker's brainwashing on the fallen Riders, enabling all Riders to unite in a final battle against Shocker.
Unfortunately, ZX was among the Riders whose existence was erased by the Rider Robo. This fate, however, was rendered moot when the Rider Robo was finally destroyed by , restoring ZX's place in history.
===Chou Super Hero Taisen===
Ryo, as Kamen Rider ZX, fought in the Team Ninja, against several Sentai Rangers and Kamen Riders teams.
======
Though he was seemingly erased as a result of Asmodeus’ manipulations, he was restored back into existence once Touma Kamiyama had helped Shotaro regained his passion in drawing out the superheroes that he wants to draw out.
During the climatic final battle itself, he can be seen fighting alongside , , and Kamen Rider Kenzan.
===Geats Extra: Kamen Rider Tycoon meets Kamen Rider Shinobi===
Ryo Murasame was forcibly teleported to the world of Shinobi because of Amakusa Shirou and supposedly brainwashed like Kamen Rider Kenzan and Kamen Rider Fuma to attack Rentaro and Keiwa. However, Ryo was immune from Amakusa's brainwashing because the power can only influence wholly organic beings while Ryo himself is a cyborg. Ryo freed Kenzan and Fuma in an instant after he had transformed, having their aid to take down the foot soldiers while Keiwa and Rentaro faced off against Amakusa.
After Ryo had finished off the foot soldiers, he brought Kenzan and Fuma to help Keiwa and Rentaro to fight. He commanded everyone to gather their energy and performed a team finisher, the Ninja Rider Kick, against Amakusa. Afterwards, Ryo left the dimension after he had bid his farewell and prayed for Keiwa and Fuma's wellbeing.

===Kamen Rider SD (OVA)===
ZX: A relatively new Kamen Rider. In a sharp contrast to his original television counterpart, the animated version of ZX is very lighthearted, and quite eccentric. He has taken a liking to messing with Black RX, as well as gambling with him for money he doesn't have. His fighting style is similar to a ninja, including the art of instant disguise (he turns into a gangster and a female tennis player) and high agility. He finds Black RX's problem with love very hilarious, although he does his best to help, which only makes things worse. His team squad includes Black RX and Rider 1. He rides on a modified version of the Helldiver Motorcycle.

==Personality==
Having lost his sister to Badan, Ryo initially fought for vengeance, though with some concern for the innocent. Proving to be a hothead, Ryo recklessly challenged anyone he deemed a threat, mistaking Riderman and Super-1 as Badan's soldiers. Upon V3's intervention though, ZX learnt the importance of justice from his predecessors, earning the mantle of "Kamen Rider" from them. 
==Abilities==
Compared to his predecessors, ZX has a limited range in combat techniques, being more reliant on agility and weaponry in battle. By using his Micro Chain, ZX can reel in or stun shock opponents, with his Cross Shuriken and Focus Bomb primarily used as long ranged attacks. While not shown onscreen, ZX also possesses a dagger called the Electric Knife within his right thigh, as well as jets stored inside his boots.
In Heisei Rider vs. Showa Rider: Kamen Rider Taisen feat. Super Sentai, ZX is shown to be capable of creating illusions from his hologram projector, meant to mask his physical appearance.
