- Dark Shinji's proclamation as the strongest of the Riders

Dark Shinji, also known as Mirror Side Shinji (鏡像の真司) is the primary antagonist in Kamen Rider Ryuki: Episode Final. Transforming into Kamen Rider Ryuga (仮面ライダーリュウガ), he is one of the 13 Kamen Riders and resembles Kamen Rider Ryuki, but with a black look similar to Ryuki's Blank Form.

In Kamen Rider Zi-O he becomes Another Ryuga (アナザーリュウガ).

13 Riders
In the 13 Riders special (alternate retelling), Ryuga was among the Riders in the ending fight, only seen there. He and the remaining Riders activated their Final Vents on Shinji, who was currently fighting as Kamen Rider Knight Survive.

Kamen Rider Ryuki: Episode Final
In the alternative continuity of Episode Final, Yui Kanzaki had already met and befriended Shinji Kido when they were both very young. As a result, the young and lonely Yui subconsciously created a duplicate of Shinji in the imaginary Mirror World. Several years later, this Shinji clone would adopt the identity of Kamen Rider Ryuga and join the Rider battle in order to pursue his goal of becoming a real person in the real world.

The Mirror World version of Shinji Kido could survive indefinitely in his own universe without any extra protection, but could only stay in the real world for a short time before he started to disintegrate.

Ryuga was twice mistaken for Ryuki. Ren had seen Ryuga attack Kamen Rider Femme while out fighting a Hydragoon, and thought Shinji had come to understand the meaning of the Rider War. He then demanded that Shinji fight him. Miho first mistook Ryuga as Shinji when Ryuga saved her before Kamen Rider Ouja could kill her. Ryuga himself had destroyed Genocider and reverted Ouja into his blank form. Femme then finished Blank Ouja off.

Kamen Rider Decade
In the World of Faiz, after Daiki takes Tsukasa's Ride Booker, Narutaki takes advantage of the situation as he takes Tsukasa into another dimension to be killed by Kamen Rider Ryuga. However, after interrogating Kiva-la on Tsukasa's whereabouts, Daiki intervenes while claiming it was to get the Faiz Gear as he gives Tsukasa back the Ride Booker.

In his fight with Ryuga, Diend summoned Kamen Rider Kiva ("A monster for a monster.") when Ryuga summoned Dragblacker, with Diend transforming Kiva into the latter's Final Form Ride Kiva Arrow form soon after. He used Kiva Arrow's Final Attack Ride to counter Ryuga's Final Vent. Diend's final attack prevailed, seemingly destroying both Ryuga and Dragblacker.

OOO, Den-O, All Riders: Let's Go Kamen Riders
Kamen Rider Ryuga was part of a group of reinforcement riders led by Akira Date/Kamen Rider Birth to aid the primary riders in defeating the Rock Great Leader. All the Kamen Riders got on their bikes and performed the All Rider Break attack which destroyed the Great Leader.

Personality
In terms of character, Ryuga was the exact opposite of his real world counterpart. While the real Shinji was kind and innocent, the Mirror World version was cruel and scheming. He was responsible for the death of Kamen Rider Femme, mortally wounding her during their fight. Near the end of the movie, he met his own fate at the hands of his real world counterpart when, after a climatic showdown, the two Riders' Final Vents collided, Ryuki surviving while Ryuga perished.

Contract Monster


Modeled after a Chinese dragon and Ryuga's Contract Monster, Dragblacker is referred as the Dark Dragon (暗黒龍).

He then goes into a kicking pose, and Dragblacker sends him flying towards the target with darkness, slamming into the target with incredible power. When used on Genocider, some of the darkness hit it, binding it to the floor, allowing Ryuga to kick it so hard, it was bifurcated.
