And this is where I go maximum sperg and point out that the Himawari Lockseed is Inves Games only, to the point where even the toy only has generic Inves Game sounds. And that it's Class D, which means it's lower class than the cannon fodder tier Kurokage. But, again, this is just me being a sperg. I think it's great that you're not just a copy of an existing rider/literally using the powers of an existing rider.

Anyway, here you go, tribute to Showa Riders, Shocker Combatmen and a bit of The Skullman all in one go.

[b]Name:[/b] Taro Yamada (or Yamada Taro in japanese)
[b]Rider Name:[/b] Kamen Rider Rivale
[b]Age:[/b] 74
[b]Gender:[/b] Male

[b]Appearance:[/b]
People who've known him for a few years tend to joke that Yamada just doesn't age. This statement is true, as he does not look a day beyond 30 despite being over 70 years old, not that anyone knows his real age. Other than that little factoid, Taro just doesn't really stand out whatsoever. He's an entirely average japanese man in every respect, not too tall or short, not too fat or thin or muscular, short black hair, clean shaven with dark brown eyes. Though nowadays he tends to dress in average, middle of the line black suits with white shirts and featureless black ties, which makes him the spitting image of the nameless faceless salaryman, the truth is that he could easily pass for most anything by wearing the right clothes, he is that kind of plain.

[b]Suit appearance:[/b]
More akin to reinforced biker leathers rather than some manner of high tech powered armor, the Rivale suit is almost entirely black and features white designs resembling a human skeleton spread throughout the entire frame, [url=http://imgur.com/YCJ6jVc]not unlike a certain dark Rider[/url], along with plain white gloves and boots akin to those eventually worn by the first Kamen Rider. Though of a much higher quality, the entire design still brings to mind the visage of the Shocker Combatmen to whoever is in any way familiar with them or their incarnations in Dai Shocker, Super Shocker or Space Shocker.

Rather than the regular Shocker Combatman mask, however, Kamen Rider Rivale wears a two-part helmet, a featureless black faceplate which covers the lower jaw up to right under the nose combined with a bone-white top made to resemble a skull, its large, black eyesockets somewhat resembling a regular rider's compound eyes if one squints a bit. The suit is also adorned with small imprints of the [url=http://imgur.com/fk5TaGv]Dai-Shocker insignia[/url]. There is one carved into the helmet's forehead, another white one on the back, right under the neck, and then two black ones adorning the back of the hands. The boots also sport the design carved into the soles.

His belt, known as the Shocker Driver EX, is an extremely simple deal, a featureless white strap with an oval silver buckle which fits handily in Yamada's hand. The buckle's centerpiece is a black medal depicting, you guessed it, the double headed eagle insignia. Yamada can materialize the belt at will, since it's part of his cybernetic enhancements, but must carry and insert the buckle manually. The entire setup is extremely resilient to all forms of damage and the buckle is unlikely to come off unless subjected to extreme trauma.

[b]Abilities:[/b]
As a cybernetically enhanced man, Yamada Taro is stronger, faster and more durable than an average human even without transforming, though since these upgrades are of low quality compared to superior inhumanoids they don't add as much of an edge as one would believe. Most full-fledged monsters are much stronger and even dedicated humans may attain a level of physical performance that matches or surpasses some of the advantages given by these cybernetic augmentations. Yamada is also quite skilled in hand to hand fighting and motorcycle riding and is something of a jack of all trades as a result of his long life and his myriad of jobs.

[b]Rider Powers:[/b]
Kamen Rider Rivale does not use weapons because of the 15 Showa Riders (counting Shin, ZO and J), only 5 of them employed any kind of personal weapon at all. Likewise, Rivale lacks any kind of form changing powers since only Stronger, Black RX and J had abilities like those, not to mention both Stronger's Charge Up and J's Jumbo Formation were straight powerups rather than any kind of specialized use forms like the Heisei riders are fond of employing. Instead, the Rivale suit greatly empowers Yamada's cybernetic enhancements, making his physical performance outstanding even for superhumans. 

The combination of Taro's martial art skills and the overwhelming strength, impressive durability, outstanding speed, the ability to enhance and control his senses with the Orbit Finder eyes and the Cochlear Searcher ears make Kamen Rider Rivale a threat to be reckoned even if he lacks any kind of fancy overblown weapon or 10 different costumes. Rivale finishes battles with the Shocker Finish attacks, which can be triggered vocally or via manual handling of the belt, and consist of gathering large amounts of crackling yellow energy into his hands or feet to deliver a powerful attack. The process is tiresome and can't be used more than once or twice without rest.

Rivale can perform the following techniques with the Shock Finish
-Shocker Punch: Any kind of punch delivered with a charged fist.
-Shocker Kick: Any kind of kick delivered with charged feet. A personal favorite for obvious reasons.
-Shocker Chop: Any kind of knifehand strike, where the energy is used to cut rather than for concussive force.
-Shocker Thrust: A stabbing knifehand strike.
-Shocker Shooting: Discharging the accumulated energy as a projectile rather than on contact. Not as powerful, but has the advantage of range.

[b]Rider Machine:[/b]
Kamen Rider Rivale's bike is the [url=http://imgur.com/a/armTf]Combat Revenger[/url], a black Zundapp KS750 sans the sidecar that's been modified to achieve Rider Machine levels of performance and durability. It's a heavy all-terrain motorcycle, not as suitable for acrobatics but powerful and capable of riding in damn near every terrain and direction imaginable, such as up buildings or across water, as well as surviving gross amounts of punishment. Rivale can summon the Combat Revenger to his location and there's few obstacles that can actually stop the bike from reaching its master.

The Combat Revenger's unused sidecar can actually transform into a secondary Rider Machine called the Side Striker. It's smaller, slower, and not as good with rough terrain as the Combat Revenger, so Rivale does not like it as much. The Side Striker makes up for all this by being a mobile weapons platform, loaded down with heavy firepower which can be used in both motorcycle and sidecar mode and being even tougher than the Combat Revenger. The main bike loses some top speed and maneuverability when the Side Striker is attached and, more importantly, it requires someone manning the guns to function, which means it goes completely unused for the moment.

While riding on the Combat Revenger, Rivale can perform another Shocker Finish known as the Shocker Ramming, where the bike is covered in a shield of of glowing energy as it accelerates to breakneck speeds, fatally crashing into the enemy. It's stronger than the regular Finish moves but requires more energy and Yamada is knocked out of his transformation shortly after performing it.

[b]Personality:[/b] 
Yamada Taro is fairly amicable, quiet and a bit withdrawn but by no means antisocial. As Kamen Rider Rivale, he has conflicted feelings. On the one hand, he greatly believes in Shocker's ideal of a unified world of superhumans and has a personal vendetta against Kamen Riders for the deaths of many like him. On the other, he also hates the leaders of the various villanous organizations for treating combatmen as disposable and realizes that Shocker's terrorist activities were perhaps not the best way to go about their goals. Though he wants to be a hero, or at least someone the public can look at with respect, he has very little idea of how to do so beyond doing the exact opposite of what he used to do and imitating the Riders of old.

[b]Backstory:[/b]
It has been over four decades since the Kamen Riders came to be and Shocker was dissolved, first fused with Geldam into Gel-Shocker after the massacre of its former members, then destroyed and reborn time and again. All eyes were on the Riders and the monsters they battled, as well as the rise of evil groups not governed by the Great Leader. And in the chaos, a nameless grunt survived. Deciding he'd had enough, enough of battling impossible odds and being a sacrificial lamb, he took the name Yamada Taro (a japanese equivalent of John Doe) and put his life of crime behind him. His affiliation with Shocker would've seemed like a dream were it not for his ageless cyborg body.

What followed were long decades of constant moving around, not staying in one place or holding down a single job for too long. It was too dangerous for both himself and the people around him, who he never allowed himself to get too close to. It wasn't a great life, but it wasn't bad either. He managed to disconnect himself from his previous self almost entirely and was only vaguely aware of the new threats and the riders that faced them. At least until he was tracked down by Foundation X. As one of the few remnants of Shocker's trailblazing technology he was of particular interest to their research, especially since coming close to capturing one of the original Riders was a pipe dream at best.

Compared to the Shocker conversion process, their research was relatively harmless, not like it made the entire situation less distressing. The Foundation's goal was to reverse enginneer the human modification technologies found within Yamada and refine them into the same level that produced the original Kamen Riders. As a test platform, they designed a special system known as the Inhumanoid Driver Experimental which would theoretically enhance a man with upgrades like Yamada's into someone that could match a Kamen Rider blow for blow. Obviously, the whole process was to be tested on a loyal member of the Foundation.

As it happens, Yamada took advantage of his own cybernetic enhancements and years of experience to escape the Foundation's grasp, taking the untested Driver and using it against the Foundation, renaming it the Shocker Driver EX. He now had power to match that of his nemeses, but found that time had given him a new perspective on things. He was no longer as bitter against the Riders and saw the harm that groups like Shocker could cause in the name of a greater good. Now that he too had great power, it was time to do things right. He would recreate Shocker as a true force for good, a group truly dedicated to advancing mankind. He was now Kamen Rider Rivale.
