He uses the Cross-Z Dragon given to him by Sento in conjunction with the Dragon Fullbottle left by his late girlfriend Kasumi Ogura to become Kamen Rider Cross-Z, the secondary rider of Kamen Rider Build. As war breaks out between Hokuto and Touto, Ryuga takes the Sclash Driver against Sento's objections and uses it with the Dragon Sclashjelly to become Kamen Rider Cross-Z Charge until the Sclash Driver and Sclashjelly were destroyed by Blood Stalk. The remains of the Dragon Sclashjelly were used to create the Dragon Magma Fullbottle, allowing Ryuga to transform into Kamen Rider Cross-Z Magma with the Cross-Z Magma Knuckle. His humanity is called into question, implying Ryuga may not even be human, which is confirmed in the following episode.

It is revealed that Ryuga is actually a part of Evolto, the being which destroyed life on Mars. Evolto eventually possessed Ryuga and became one once again. However, they were soon separated and Evolto's DNA was removed from Ryuga as a result. However, using the Great Dragon Fullbottle he created from the stolen Dragon Evolbottle, Banjo is able to transform again and becomes Kamen Rider Great Cross-Z.
Arrival on Earth
In 1994, 13 years before Sky Wall Incident, an unmanned space probe from Japan landed successfully on Mars and returned to Earth. After its return to the Nanba Heavy Industries Institute of Synthetic Science, the probe unexpectedly brought back an alien specimen in the form of glowing red slug-like creature, later revealed to be a portion of Evolto, deliberately sent to the probe, with the intent of finding another planet to destroy. His specimen made its way out of the probe and attempted to possess and plant itself into Yuri Banjo, a security guard who was stationed there with her husband.
Present
As an adult, Ryuga became a professional fighter, eventually getting engaged to Kasumi Ogura. By the age of 22, Ryuga earned a lifelong ban from fighting for throwing a match; it is implied that he accepted a bribe in order to pay for the frail Kasumi's medical bills. To help his search for a new job, Kasumi directed Ryuga to Takumi Katsuragi, a researcher at the Touto Institute of Advanced Matter Physics, who was apparently looking for an assistant. However, when Ryuga came to Katsuragi's home to apply, he found the corpse of "Katsuragi" inside. Moments later, Touto's Guardians arrived and apprehended Ryuga. It would be revealed that it was Soichi Isurugi who called Ryuga the murderer, which would give Ryuga a ten-year sentence in prison.
The Rabbit Tank Meets Dragon
Ryuga was eventually found by Touto's Guardians, who attempted to recapture him. Ryuga managed to fend off the Guardians and escaped before he was apprehended by Sento Kiryu, who had tracked him upon noticing his Smash-like energy readings. Upon realizing that Ryuga had undergone a similar experience, Sento began interrogating Ryuga in hopes of uncovering his past, despite Ryuga's frustrated belligerence. The two were interrupted by Strong Smash, who attacked Ryuga. However, Ryuga was saved by Sento, who transformed into Kamen Rider Build and defeated the Smash. Ryuga recognized the Smash's human identity as one of his fellow victims but was frustrated to find that the man had no memories of the experiments.
Burn Smash incident
Sento brought Ryuga to the basement lab of the nascita café, where the former had been living for the last year. After meeting Sento's accomplices, Souichi and Misora Isurugi, Ryuga explained the circumstances that resulted in his arrest. However, the story was interrupted by Sawa Takigawa, a freelance journalist who had entered the base. As a precaution, Ryuga was chained up in the lab, much to his chagrin. Misora took the time to explain the Fullbottle purification process to Ryuga, as well as Sento's job. Noticing Misora's smartphone, Ryuga goaded her into proving her ability to purify Smash energy.
Continuing the Search
After some searching, Ryuga managed to contact Nabeshima. Nabeshima revealed that his family was being threatened by Faust, upon which Ryuga offered to smuggle them out of Seito to safety in exchange for Nabeshima testifying for his innocence. With Sawa's help, Ryuga snuck to Seito. Upon retrieving Nabeshima's wife and daughter, Ryuga and Sawa were attacked by hijacked Guardians, barely escaping with their lives. Ryuga arrived in Touto to aid Build in taking down Nabeshima, who had been subjected to two Smash transformations by Faust.

Cross-Z charges up
In one fight, Ryuga was granted the Kuma and Televi Fullbottles by Grease as a concession when the Hokuto Three Crows interfered in their battle and breaking the rules. After giving the new pair to Sento, Ryuga saw that nascita finally had a customer in the form of Massugu Ubukata. Providing his customer with a canned coffee, Ryuga, foreseeing a boon in business, set out to acquire a bountiful stock of coffee beans, only to find the shop as vacant as usual when he returned.

Cross-Z Charges into Hell
Seito proposes a 3-on-3 representative battle to Touto. Ryuga is participating Round 2 against Fu Washio. Much to the surprise of Ryuga, the announcement depicts the name his opponent is "Hell Bro's", which he had never heard before. As Ryuga prepare his transformation, he is interrupted by the sudden appearance of the Gear Engine on Fu's hands. Fu uses it along with his personal Gear Remocon to transform into Hell Bro's, completely overwhelming Ryuga's expectations. However, Ryuga didn't waver and proceed to transform into Cross-Z Charge.
Sclash Driver Destroyed, and Going Magma
After Vernage resurfaced from Misora's bracelet, Blood Stalk got his transformation knocked out after the queen blew a strong gust of wind at him. He then tried to attack her again, but Ryuga stood in the way. However, this resulted in Ryuga's Sclash Driver getting destroyed, and the Dragon Sclashjelly overheated to a burnt ball of ash. Back in nascita, the Dragon Sclashjelly reacted to Ryuga's emotions, creating the Dragon Magma Fullbottle. Seeing this, Sento later made the Cross-Z Magma Knuckle for Ryuga to use with it as it was too dangerous for the Build Driver alone. This, in turn, helped Ryuga fight off Blood Stalk and Hell Bro's with ease.
Ryuga, the Human Race's End? & Possessed by Evolto
Ryuga was told by Evolto that he was the same as him, the one who would destroy the world. Albeit initially refusing to acknowledge it, Ryuga finally determined to use his power as a Kamen Rider to fight for love and peace, the very same ideal that Sento believes in and strongly holds onto. Later on, Ryuga was possessed by Evolto, as his Hazard Level had reached 5, the amount needed to use the Evol-Driver, becoming Evol Dragon Form.
Abilities:
- Hand-to-Hand Combat : Ryuga is a skilled fighter, having fought professionally before getting a lifelong ban.
- Smash Energy Signature : Since he was exposed to the Nebula Gas, Ryuga gives off an energy signature similar to a Smash, which alerted Sento to his location.
- Extraterrestrial Physiology : Ryuga's body was created from Evolto's essence, brought back from a Martian probe. This allows him to utilize the Pandora Box's power like Stalk (albeit unintentionally) and absorb the same power needed to complete the Dragon Magma Fullbottle. Furthermore, his eyes will glow red while doing so.
- High Hazard Level : Initially, Ryuga's Hazard Level is above 2.0, allowing him to retain his humanity after exposure to Nebula Gas while still gaining physiological powers from it. According to Blood Stalk, while fighting, Ryuga can raise his Hazard Level, having raised it as far as 2.7 in their fight. Eventually, he was able to raise his Hazard Level to 3.0, which is high enough to use the Build Driver. Continued fighting as Cross-Z allowed him to quickly raise it even further to 4.0, enabling him to use the Sclash Driver. During his fight with Evolto before being possessed by him. his Hazard Level was measured to be at 4.7, 4.9, and finally 5, a Hazard level that a human cannot achieve. After remembering the destruction of Mars when he was part of Evolto, Ryuga's Hazard level rose to 7.
- Hazard Level Escalation : Although the full extent s unclear, Ryuga's Hazard Level grows at a faster rate than any other Kamen Rider, to the point where his strength grows noticeably in a single fight Superhuman Strength : Ryuga has displayed enhanced strength: he was able to fight off numerous Guardians on his own, and break metal chains with his bare hands.
- Pandora Box Manipulation : His true Martian origin allows him to manipulate the structures of Sky Wall by touching the Pandora Box.
- Dragon : Ryuga's punches give off powerful shockwaves. Notably, his strong synchronization with the Dragon Fullbottle causes his power to increase with each use. Currently, Ryuga's synchronization is high enough that he can defeat a Hazard Smash while untransformed.
- Great Dragon : Similar to the effects of the normal Dragon Fullbottle, Ryuga can perform powerful punches. However, Ryuga's punches are now strong enough that they are able to damage Kamen Rider Evol
- Sclash Driver : Although the Sclash Driver gives Banjo tremendous power, its usage slowly turns Banjo into a more aggressive person and gives him an addiction to battle. Furthermore, the driver administers electrical shockwaves to the user after a period of time, canceling his transformation and rendering him unconscious. After learning from Sawa that Sento built a failsafe to destroy the Hazard Trigger and kill himself, Banjo overcomes his guilt and turns into Cross-Z Charge to stop Sento in his HawkGatling Hazard form. During the fight, the Sclash Driver begins to increase his aggressiveness, yet he manages to overcome it by reminding himself to save Sento, thus gaining control over his Cross-Z Charge form.
- Cross-Z Magma Form : While utilizing Cross-Z Magma, Ryuga will get hotter over the course of the battle, eventually resulting in pain due to the intense heat. While Ryuga has usually defeated the opponent by the time he starts to feel any side effects, remaining in the form for too long or transforming several times consecutively will put him in danger of serious harm.
- Evolto's Memories : Because a part of Evolto merged with Banjo when he was still in his mother's womb, Banjo shares his memories. Banjou normally cannot recall these memories, but once Evolto attained his complete form again, he started suddenly experiencing fractions of them. Seeing memories of Evolto's destruction of Mars causes Banjo to become incredibly aggressive, to the point where he continues to attack enemies that have already been defeated and comes close to killing opponents. However, he is no longer susceptible to these memories after Sento used Genius Form to transfer Vernage from Misora's body to Banjo's, leading to Vernage's power neutralizing Evolto's effect on Banjo.
