Alternative

The Alternatives (オルタナティブ, Orutanatibu?) are fictional characters in the tokusatsu production of the TV series Kamen Rider Ryuki. They were mimicries of the 13 Kamen Riders. Two Alternative suits were known to have been produced - a production model called Alternative and a prototype called Alternative Zero (オルタナティブ・ゼロ, Orutanatibu Zero?). Alternative and Alternative Zero's true identities were, respectively Hajime Nakamura and Hideyuki Kagawa. Along with Kamen Rider Tiger, the two were fighting to close the Mirror World and opposed Kanzaki's Rider War.

The two suits were identical except for a few minor differences. Alternative Zero's suit had blue accents and silver cables while Alternative's had orange accents and black cables. Alternative Zero was also decorated with silver stripes labeled "Trial Prototype-00" on both sides of the body. Because they are modeled after crickets, the Alternatives resemble the older Kamen Riders such as Kamen Rider V3 and Kamen Rider Super-1 in terms of appearance. Alternative Zero and Alternative were both killed the same way, Tiger betrayed them and destroyed their decks, causing them to dissolve in the Mirror World.

Fictional character biography (Alternative Zero)
Prior to Kanzaki's experiment, Professor Hideyuki Kagawa wandered into Room 401 one day and happened to see Shiro Kanzaki's notebook lying on the floor. He scooped it up, opened it and gave every intriguing page a once-over before Kanzaki snatched it from him. However, Professor Kagawa has a photographic memory. After learning the severe nature of Kanzaki's experiments, Kagawa began to duplicate Kanzaki's work in order to close the Mirror World. To that end, he formed a relationship with Satoru Tojo and Nakamura. Kagawa eventually created the Alternates. Kagawa was a married man, with a young son named Yuuta. Though he deeply loved both his wife and son, he did not let Kanzaki's threat to their lives deter him from his course to close the Mirror World. Unfortunately, he died for it at the hands of Satoru, who did it based on the man's word that a 'hero must sacrifice the one they love.' Satoru would come to regret his deed in the name of heroism.

Fictional character biography (Alternative)
Hajime Nakamura was originally one of the staff under Professor Ejima at Lab 401, but he was sick the day Kanzaki and Ejima began the experiments. Upon learning what occurred, Nakamura never forgave Kanzaki and his sister, for the events that occurred. Hajime Nakamura studiously avoided any questions about the lab, Kanzaki and what happened there, when encountered by Yui when she came to Seminin University to learn more her brother's actions and later Reiko. Nakamura eventually joined Professor Kagawa to stop the Rider War as Alternative. However, Nakamura's reasons were for vengeance and thus was killed by Satoru because of those reasons.

Advent Cards
Unlike the other Advent Cards, Alternative and Alternative Zero's cards are different in appearance; the terminals and images are printed crosswise unlike the original Advent cards that have theirs printed lengthwise, and are given the title, "Alternative Advent Card Alchemy System" at the back. Also, there are green characters on the cards, which may give information to the Visor on what kind of card is swiped. Because their equipment was designed by themselves, the V-Buckles' and Card Decks' appearances were different from the other Riders.

Slash Visor (スラッシュバイザー, Surasshu Baizā?) The card reader of Alternative Zero/Alternative was mounted on his right forearm. The visor voice was different from those of real Riders, the voice was female. Another difference was how the cards were used with the visor. The cards were swiped (similar to the rousers in Kamen Rider Blade), which burned up and disappeared when the card was vented.
