- 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), created by Heure and Sworz. .

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.

Kamen Rider Zi-O
Heure was able to meet Dark Shinji thanks to Tsukasa's information about "that" another world. Heure learned that Dark Shinji had once been defeated in a Rider War, but as long as the real Shinji Kido exists, Dark Shinji will continue to manifest. Thus, Heure gave him the Ryuga Another Ridewatch, enabling him to transform into an Another Rider.

Sougo and Geiz try to defeat the Another Rider but to no avail, as all the attacks they dealt were reflected back. Geiz searched for White Woz to ask for assistance to take him down, only to have White Woz attack the real Shinji instead, as he stated that if Shinji is gone then so will Dark Shinji. This made Dark Shinji fight against White Woz and he reveals himself as Another Ryuga, and proved to be far too strong even for White Woz. Even Woz Futuring Quiz's ability had stated that Another Ryuga can't be defeated.

After Another Ryuga's will to fight went down, he returns to Mirror World, but Sougo tried pulling him back, which resulting in Sougo being dragged into the Mirror World as well.

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 was seemingly perished.

In Zi-O, he is a manifestation of Shinji's rejected dark heart. Therefore, after becoming Another Ryuga, he targets the readers of ORE Journal who Shinji secretly blamed for the closure of the magazine.

Powers and Abilities

 * Mirrored Human Physiology
 * Immortality: As long as his real counterpart is alive, he cannot be defeated.

Weaknesses

 * Real World: Creatures from the Mirror World cannot exist in the real world for too long without being disintegrated. This also means that if he ever continues to exist outside of the Mirror World, his powers will be weakened significantly.
 * Shinji Kido: If Shinji Kido is killed, Dark Shinji would cease to exist as well. White Woz predicted that this can even override the immortality of the Another Rider.

Contract Monster


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