Shigeru Jo

Shigeru Jo (城 茂) is the protagonist and eponymous character of the 1975 Kamen Rider Series Kamen Rider Stronger. Shigeru was reconstructed as Electric Human Stronger (電気人間ストロンガー) by the evil organization Black Satan before he escapes with fellow cyborg Yuriko Misaki, thus renaming himself as Kamen Rider Stronger (仮面ライダーストロンガー). Stronger's primary motif was that of electricity. All his attacks were based on electricity, and the cyborg aspect of his body is much more prominent than in the previous series; for instance, his hands were metal coils that had to be covered when he didn`t transform.

History
Shigeru joins the evil organization Black Satan after the death of a close friend, one whom he considered his mentor. Promised power, and fueled by a desire for revenge, he undergoes surgery to become one of Black Satan's super warriors. However, Shigeru knows that Black Satan were in fact the murderers of his friend; he was only using Black Satan in order to gain new powers. The newly powered up Shigeru escapes from the Black Satan headquarters before they can brainwash him into following their campaign of evil.

Frustrated, Black Satan scientists devise a plan to capture and kill the warrior they have just created, along with continuing the goal they've had all along: world domination. Shigeru plans on fighting back in his new form, called Kamen Rider Stronger. While escaping from Black Satan, Stronger meets Yuriko Misaki another cyborg warrior created by Black Satan. They team up, with Yuriko now becoming Electro-Wave Human Tackle. The two eventually meet Tōbei Tachibana as well.

Stronger, Tackle, and Tōbei fight valiantly against the evil cyborg forces of Black Satan, continually meeting the head agents General Shadow, and the One-Eyed Titan. The Titan is defeated in episode 13, but manages to return in episode 17 as the One-Hundred Eyed Titan, posing an even greater threat than before. Despite sharing the similar goals of defeating Stronger and conquering the world, General Shadow and the Titan cannot seem to agree on a few other issues—for instance, which one of them gets to kill Stronger. Often, their bickering inadvertently allows him to escape their wrath.

In episode 26, Stronger is able to topple Black Satan once and for all. With his former organization in ruins, General Shadow forms the "Delza Army" to continue his malicious goals. Stronger's struggles against them were much more tense as the Delza leaders were immune to his normal electric attacks. There were two further defining moments for the series: first, in episode 30, Tackle sacrifices herself to save Stronger from Doctor Kate, a Delza Army general. Her death forever haunts Shigeru, pushing him into undergoing surgery to gain a devastating new power—the ability to power up into a new, stronger, form—"Charge Up!".

Ultimately, all the former Riders, Kamen Riders 1 & 2 from the original Kamen Rider, V3 & Riderman from Kamen Rider V3, X from Kamen Rider X and Amazon from Kamen Rider Amazon, all appear in the final few episodes to help Stronger finally defeat the Delza Army and General Shadow. This sequence of episodes has attracted some praise from fans.

Skyrider
The evil organization Neo-Shocker moved ahead with its plans of global genocide. Shigeru Jo, Kamen Rider Stronger, alongside the other Seven Legendary Riders fought around the world against it, leaving Japan's protecting to the new Kamen Rider, Hiroshi Tsukuba, Skyrider.

After fighting through Neo-Shocker's forces in Southeast Asia, Stronger returned to Japan just in time to save Skyrider from Neo-Shocker's monsters Sai Dump and Kurageron. This event marked Skyrider's first encounter with one of the Seven Legendary Riders whom preceeded him. Soon after, Stronger and Skyrider fought together against the two cyborg monsters of Neo-Shocker with Stronger destroying Kurageron with the Super Electron Drill Kick while Sai Dump was defeated by Skyrider.

Eventually, Neo-Shocker gathers a Second Generation Cyborg Corps in Japan, led by Gurand Bazarmy, known as the Strongest Cyborg on Earth, and also plans to launch a direct offensive with an experimental tank, the Varithium Cannon, led by Hirubiran. To save Japan, the seven Riders return and, alongside Skyrider, destroy the experimental Varithium Cannon and Hirubiran. However, they are soon challenged by Gurand Bazarmy and his troops.

Neo-Shocker troops start kidnapping many people around Japan in order to work as slaves in their operation to bring about a large volcanic eruption in Japan. The seven Riders spread around Japan to fight against various attacks from Neo-Shocker. In a later battle, Skyrider is easily wounded and left unconscious while trying to face Gurand Bazarmy. While he recovers, the Riders communicate telepathically with the unconscious Hiroshi Tsukuba. The Riders tell Skyrider that he should go through an intense training where he'd receive their powers, multiplying his strength 20 times to fight against Gurand Bazarmy again.

After Skyrider's training is finished, all Riders leave to face Neo-Shocker again. Skyrider faces Gurand Bazarmy, while the Legendary Seven fight against Neo-Shocker's Second Generation Cyborgs troops. Gurand Bazarmy and his army quickly fall before the Riders. After the battle is over, the Seven Riders leave Japan again, to fight Neo-Shocker all over the world, while Skyrider remains to protect Japan.

Neo-Shocker makes an alliance with an alien, the self proclaimed Galaxy King, and starts an operation to explode Mount Fuji. When Skyrider is ambushed by another troop of second generation Second Generation Cyborgs led by Jaguar Van, all seven Riders arrive to face their forces and allow Skyrider to proceed. After the battle, all 8 Riders leave to fight Neo-Shocker elsewhere.

Having located Neo-Shocker's main base, Shigeru and Hayato summoned their fellow Riders from across the world, uniting the Seven Legendary Riders. They head to Neo-Shocker's underwater base, only to be faced with a giant dragon, Neo-Shocker's, Great Leader himself. Stronger's and everyone else's attacks prove to be ineffective against the Great Leader, however, they hold on long enough for Skyrider to arrive. Skyrider stuns the Great Leader by shooting his foot with a bowgun, and, using the opportunity, all Seven Legendary Riders hit him with their Rider Kicks, knocking down the giant. However, he was still alive, and decides to explode alongside a giant bomb, taking out not only himself, but Earth itself by destroying it`s atmosphere. The eight Riders combine their powers and use Skyrider's Sailing Jump together, grabbing the Great Leader and taking him to the distant sky, where they all explode, all eight Riders seemingly perishing alongside it when in truth they were blasted across space until they regrouped in Super-1.

Super-1
Kazuya Oki, Kamen Rider Super-1, fought against the Dogma Kingdom to stop them from awakening an ancient weapon. However, in his way stood the Dogma Revenge Corps, troops of rebuilt cyborgs from Dogma Kingdom and Neo-Shocker. When he seemed overwhelmed by his enemies, Rider 1 suddenly reappeared, followed by the other 8 previous Riders, all alive. V3 tells Super-1 to let that battle in their hands, and soon they fight against Dogma's troops to open way for Super-1. V3 briefly faces Dogma Fighters, Gyosutoma & ArigiThunder. Fighting alongside Riderman, V3 finishes off Zombieda with a throw while his partner does the same to Ganigannii. V3, Riderman and X go on to use a triple Revolving Kick to finish off, respectively, Kamagirigan, Snakecobran and ArigiThunder. Thanks to the help of the Riders, Super-1 reaches Dogma's troops on time and stops them. After the battle, the Riders show themselves to Super-1 and his friends, and promise to fight for humanity's future together.

ZX
The Badan Empire, led by Ambassador Darkness, spread its claws around the world, and, to face it, the nine Riders came together. When Badan initiated its Space Break System, a destructive dimensional weapon, all 9 Riders gathered in Japan to stop them.

Badan's base was located, and all 10 Riders went towards it. Ambassador Darkness 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 Jūjin Ōmukade, a revived Geddon monster. however, before the battle could be finished, Ambassador Darkness attempted to use hostages to make the Riders surrender. His plan fail due to Super-1's interference and Ambassador Darkness decides to use the Space Break System, only to destroy Badan's remaining troops. After V3's call, the ten Riders gather their power with Rider Syncro, weakening Ambassador Darkness and allowing ZX to finish him off. After Darkness is defeated, evil energy gathers in the shape of a giant skull, The Generalissimo of Badan, giving farewell to the Riders and laughing at them.

V3 bestows upon ZX the official name Kamen Rider 10 and soon all Riders part ways again to continue their battle against evil around the world.

BLACK RX
Kamen Rider Stronger, 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. Stronger 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 Stronger 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 Stronger 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, Stronger 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, Harmful Nimp. 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, Colonel 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 Harmful Nimp 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 Stronger, 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, General Dasmader appears alongside a group of Chaps and attacks Kohtaro. Stronger 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. Stronger participated in the tournament and fought against Kamen Rider Blade, though he did not make it to the final where Decade emerged victorious. Stronger and the other defeated Riders disappeared into a dimensional wall and were taken for 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. Stronger 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. During the battle, he is seen defeating a few Shocker Combatman and a Rat Fangire, and throwing a few more enemies off the hillside with Kamen Rider ZO and Kamen Rider X. When Shadow Moon was thrown onto the Dai-Shocker Castle, Stronger participates 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, King Dark, 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, Stronger, alongside the other Riders, turned into giant Kamen Ride Cards to power up the giant Decade's Final Dimension Kick, destroying King Dark. After the battle was over, Stronger 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 Stronger, 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, Stronger 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.

Movie War Mega Max
A meteor shower hit various points of Earth, bringing with it time anomalies, monsters and the interest of the shadowy organization Foundation X. In the Middle East, holding off all three grunt types, Stronger fails to stop Foundation X from retrieving the SOLU.

Afterwards, Stronger gathered with the other Seven Legendary Riders in Japan and infiltrated a Foundation X secret airport to stop Lem Kannagi, who was leading a plan to control energy sources around the globe and also their operation regarding the meteors. However, they're all taken by a trap and Stronger is sealed in a Core Medal.

Later, Kamen Rider Fourze finds the seven sealed Riders, and with Kamen Rider OOO's help, releases all of them at once. V3 warns them that Kannagi will receive a full charge of Cosmic Energy if he reaches space, which would make him invincible according to Riderman, and he needs to be stopped now. Meanwhile, copies of the Greeeds and Sonozaki Family Dopants approach the group, standing in their way. The Seven Riders stay behind facing them, while Fourze and OOO head to stop Lem Kannagi. Stronger fights against a copy of the Terror Dopant and finished him off with his Stronger Electro Kick.

Meanwhile, OOO and Fourze managed to stop Lem Kannagi in space. Afterwards, in a scene added to the movie's Director's Cut, the young Riders, and also another Rider from the future, Aqua, gave goodbye to each other and to the veterans, everyone parting ways afterwards.

Super Hero Taisen
During the Super Hero Taisen incident, Stronger and the other six Legendary Kamen Riders were confronted and killed by Captain Marvelous/Gokai Red. When Tsukasa and Marvelous revealed that the whole incident was planned, Stronger and the rest of the 'deceased' Kamen Riders arrived from the dimensional rift they were sent to and joined up with the 36 Super Sentai teams to defeat the Dai-Shocker/Dai-Zangyack alliance.

Kamen Rider Taisen
As one of the 15 Showa Riders, Stronger fought in the battle against the 15 Heisei Riders in Zawame City.

Stronger clashes with Kabuto in Rider Form after the latter jumped out of the building he crashed into, with Kabuto having the upper hand with his Clock Up features. Thinking smart, Stronger fires a 360 degree Electro Fire onto the ground, stunning Kabuto. Thinking he had him, Stronger jumps at Kabuto with a Stronger Den Kick, only for Kabuto to defeat him with a Rider Kick at Clock Up speeds.

Stronger 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, Stronger fought with the Showa Riders in a final showdown against the Heisei Riders. Stronger took on Blade, enduring his Lightning Sonic. The battle was ended when Rider 1 and Gaim reconciled on the differences of the two sides of Kamen Riders.

Due to the timeline alteration caused by Shocker, Stronger became one of the brainwashed Riders in that timeline, donning the name of Shocker Rider Stronger. Following V3 and Riderman alongside X-Rider and Amazon, Stronger confronted rebel Kamen Riders 3 and Drive but was intercepted by the rapid Kamen Rider Mach as he rode in to defend Drive on his Ride Macher. Outmaneuvered by Mach's superior speed, Stronger and Amazon were defeated by his Full Throttle Kick Macher while X was beaten by Rider 3.

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, Stronger 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.

Surviving the onslaught of the History Modifying Machine, Stronger fought and destroyed Shocker's General Shadow with the Stronger Den Kick shortly before the Rider Robo was destroyed along with the machine by. Among the remaining Riders who witnessed the farewell of Kyoichiro Kuroi as the perversion of history was reversed, Stronger's place in history was restored.

Chou Super Hero Taisen
An iteration of Kamen Rider Stronger from the Game World faced off against but was soon enough defeated by Zyuoh Tiger's rapid scratches.

Personality and influence on the franchise
The other primary characteristic of the series is Shigeru's bravado and eccentric personality. For instance, in the first episode, he instructs some Black Satan henchmen he encounters to call him Jō-san or Shigeru-san, the informal forms of his name because he'd already introduced himself. He was also somewhat cocky and disrespecting as shown in his earlier encounters with Tachibana Tobei. he does however, mean well and matures more as the series progresses. In Skyrider's series, Shigeru acted more mature as proven through his actions. He wears various t-shirts emblazoned with the letter "S", along with numerous other items of clothing, including a denim jacket with a rose emblem. Stronger's entrance is also a hallmark of the series, with his opening introduction and accompanying whistle a particular highlight. This recurring sequence has been compared to a similar one in Kikaider.

Indeed, Kabuto was greatly influenced by Stronger. Not only are both Stronger and Kabuto based on the same type of beetle, Stronger's Rider Machine is named "Kabutoroh". Beyond these superficial similarities, Kabuto and Stronger, or, more accurately, Shigeru and Souji Tendo, the title character of Kabuto, share a similar philosophical outlook and eccentric attitudes toward life and others, often commenting wryly on combat as it occurs.

Fighting skill
Since he was a normal person, Shigeru Jo was a football player showcasing his strength and stamina. As Kamen Rider Stronger he then had access to electricity which he had to be careful with around normal people.

Using electricity as a weapon, Shigeru swiftly shoots bolts of electricity to stun his opponents then attacks his opponents while they're stunned. After getting his Charge Up form, Shigeru had to speed up his fighting style to not suffer the drawbacks. While in Charge up form, Shigeru quickly weakens his opponents, then uses his finishing moves to discharge himself.

Forms
Additionally, the "form changer" motif makes its first appearance in Stronger. Stronger's "Charge-Up!" mode predates Robo Rider and Bio Rider of Kamen Rider Black RX, and the primary themes of the Heisei and Neo-Heisei eras starting with Kamen Rider Kuuga, the main characters' ability is to change forms during battle to adjust varying situations. Kamen Rider Kabuto, where each Rider character can shift between a bulky armored form and a lightly covered, fast form, also features this concept prominently.

Earlier Kamen Riders had "charge up" modes but without a change in appearance. Riders 1, 2 and V3 simply had a charge up sound effect. Riderman mysteriously pops out his helmet and wears it which inexplicably changes him fully. Kamen Rider X had smoke pour out of his body.

While stronger than most of Black Satan's soldiers, he soon found himself outmatched by the Delza Army's soldiers and couldn't quite as easily defeat them until gaining his Charge Up Form. It seems that by gaining his Charge Up form, Stronger's normal form became even more powerful since his attacks, while unable to outright destroy the Delza Army's soldiers, managed to at least weaken them.

In World of Stronger, Kamen Rider Decade gave a Final Form Ride to Stronger.

Electrer


The Electrer (エレクトラー) is Stronger's transformation belt which is powered by electricity.

Kamen Rider: Battride War Genesis
Stronger is among the Showa Riders who make their Battride War debut in this game. In his normal state outside his final form Charge Up, his playstyle terminology is similar to those of EX/Multiple Level Super gauge in 3 levels, like in fighting game's Street Fighter III. Stronger can fill a high amount of Electro Gauge while performing a special move. Once Electro Level Gauge is full, Stronger, depends on which level he is in, boosts his Electric powers to increases/changes the attacks' damage properties, such as upgrading his Electro Fire into the Level 3 exclusive Electro Waterfall. The Electric Boost activation can only be used 3 or 2 times if the Electro Gauge is at Level 3 or 2, which slows the timer.
