Ryuga is a hot-blooded and impulsive man, tending to lash out quickly. While nowhere near as intelligent as Sento, Ryuga prefers to confront problems directly using his fists and doesn't want to involve other people in his own problems. Also, unlike Sento, he does not overthink things, preferring to use common sense, as shown when he was easily able to guess two Best Matches on his own. He is shown to easily get startled, especially when the bell goes off indicating a Fullbottle is ready.
Beneath his tough exterior is an honest, selfless and honorable individual. It is implied that the cheating that banned him from fighting was to get money for his fiancée's medical treatments. Ryuga also has a friendly side, such as when he encourages Takehiko after Build removed the Smash essence from him.
Ryuga is also shown to have a selfless side, as when he attacked Blood Stalk out of anger for the sake of both Sento and Misora, completely disregarding the fact that Stalk framed him. He also directly apologize on Sento Behalf to the remaining Hokuto Three Crows, partially blaming himself due of letting Sento use Hazard Trigger for his own sake. Ryuga's personality began to alter upon his constant usage of the Sclash Driver, much to Sento's warnings of the side effects. He became more aggressive and desperate to become more powerful. However, his honor still stood as he revealed that he didn't listen to Sento because he wanted to repay his debt to him, which turned into his own strength for Sento's sake.
Abilities:
- Hand-to-Hand Combat : Ryuga is a skilled fighter, having fought professionally before getting a lifelong ban. 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. Originally, in a fight against the former, his Hazard Level was 3.0, which is high enough to use the Build Driver. Recently, however, his continued fighting as Cross-Z raised his Hazard Level to 4.0, enabling him to use the Sclash Driver.
- 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.
- Smash Energy Signature : Since he is exposed with the Nebula Gas, Ryuga gives off an energy signature similar to a Smash, which alerted Sento to his location.
- Fullbottle Augmentation : By using a Fullbottle in his hand without transforming, Ryuga can gain abilities based on said Fullbottle's traits:
- 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, it gets to the point where Ryuga is strong enough to even defeat a Hazard Smash while as a human.
- Weakness:
- Short Temper : Despite being a capable fighter, Ryuga is shown to be easily provoked in most situations. When combined with the priority to prove his innocence, it sometimes caused a major sidetrack in Build's battles against Smash (such as transforming Tatsuya back into Press Smash just to locate Faust's base) without even forming the next phase of his plans.
- Sclash Driver : Although the Sclash Driver gives Banjou tremendous power, its usage slowly turns Banjou into a more aggressive person and yearning for power. Furthermore, The driver gives Banjou electrical shockwaves after a period of time, cancelling his transformation and rendering him unconscious. After learning from Sawa that Sento built a failsafe to destroy the Hazard Trigger and kill himself, Banjou 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 increasing his aggressiveness, yet he manage to overcome it by reminding himself to save Sento, thus gaining control over his Cross-Z Charge form.
