Powers and Abilities

 * Hand-to-Hand Combat: Ryuga is a skilled fighter, having fought professionally before being banned for life after a bribing incident.
 * Smash Energy Signature: After he had escaped after being exposed to the Nebula Gas, Ryuga gave off an energy signature similar to a Smash, which had alerted Sento to his location.
 * Extraterrestrial Physiology: Ryuga's body was created from a piece of Evolto brought back from a Martian probe. This allows him to utilize the Pandora Box's power like Stalk, albeit unintentionally. His eyes glow red when he uses his powers.
 * High Hazard Level: Initially, Ryuga's Hazard Level had been above 2.0, allowing him to retain his humanity after his exposure to the 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 had been measured to be at 4.7, 4.9, and finally 5, a Hazard Level that an ordinary human cannot supposedly achieve unless via special means.  After remembering the destruction of Mars when he was part of Evolto, Ryuga's Hazard Level rose to 7.
 * Hazard Level Escalation: Due to being created from Evolto, 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, forcing his opponents to resort to low blows.
 * 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.
 * Fullbottle Augmentation: By holding a Fullbottle or Evolbottle in his hand while untransformed, Ryuga can gain abilities based on said Fullbottle's traits:
 * Dragon Fullbottle: 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.

- Transformation announcement

Rider Statistics Ability Perimeters: Ryuga transforms into Kamen Rider Cross-Z (仮面ライダークローズ) utilizing the Cross-Z Dragon, which adapts the Build Driver's two slots into one, allowing him to use only the Dragon Fullbottle to transform.
 * Rider Height: 197 cm.
 * Rider Weight: 102.4 kg.
 * Punching Power: 27.6 t.
 * Kicking Power: 33.7 t.
 * Maximum Jump Height: 57.7 m.
 * Maximum Running Speed: 100 m. per 3.2 sec.

Utilizing Cross-Z, Ryuga becomes a force to be reckoned with, blowing far past Build, Night Rogue, and Blood Stalk's Ability Perimeters. It possesses a greater punching power than Build's GorillaMond Form, has a stronger kicking power than Build's KeyDragon Form, and exceeds RabbitTank Form's maximum jump height. Though it loses to some of Build's more agile forms, it is still faster than both Night Rogue and Blood Stalk.

Cross-Z has unique features that help differentiate it from Build's normal Halfbody-based forms, most notably the addition of the Drago Live Razor (ドラゴライブレイザー) body-shoulder armor pieces at the front.

Cross-Z's personal weapon is the Beat Closer. After acquiring the Cross-Z Magma Knuckle, he occasionally uses it in this form as well.

It is unknown if Banjo can still access this form, as he has not been seen using since the debut of Great Cross-Z, nor since the Dragon Fullbottle turned silver.
