Kamen Rider Ryuga is a dark, Mirror World version of Ryuki. He is contracted to Dragblacker, a dark version of Ryuki's Dragreder. His Visor, the Blackdragvisor (ブラックドラグバイザー, Burakku Doragu Baizā), is equipped on his left arm. Like Ryuki, Ryuga's parameters are balanced. However, they are heightened to the point where Ryuga is the strongest out of all of the 13 Riders, with the exception of those using a Survive Advent Card.By using his Final Vent, Ryuga can execute his finisher, the Dragon Rider Kick (ドラゴンライダーキック, Doragon Raidā Kikku), in which he jumps into the air with Dragblacker flying behind him. Dragblacker then breathes dark blue fire at Ryuga, propelling him into a flying kick that strikes the enemy.
