|This article is about a/an rider form used by several identities in Kamen Rider Ryuki.|
The Alternative (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 and not considered true Kamen Riders, only Rider-like, as its wearers do not acknowledge themselves as 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). Within the series' narrative, the Alternative is also referred to by the sub-class known as Pseudo-Riders (疑似ライダー Giji Raidā).
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 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 Shiro Kanzaki's Rider War.
Those original series of Alternative Zero and Alternative were both killed the same way - Tojo betrayed them and destroyed their decks, causing them to dissolve in the Mirror World.
Hideyuki Kagawa, as Alternative Zero, shows up with an army of twelve Alternatives in order to destroy Ryuga. As they prepare to attack Ryuga, Yui Kanzaki shows up. Kagawa laughs, saying Yui is the source of all their troubles and if she dies everything will end. They attack her instead, but Ryuga, having his sanity returned, shields her, reverting to human form and dying. Kagawa is shocked that there's "a Kamen Rider who would give up their life for someone". Yui says she has a favor to ask of him.
In Kamen Rider Decade, Alternative is an enforcer of the Dark Riders who appeared in the World of Negatives alongside Ryuga, Orga, Dark Kabuto and Dark Kiva. He was later killed by Kamen Rider Diend. Curiously, even though his suit was identical to Alternative Zero's, the character is officially identified only as Pseudo Rider Alternative.

- Main article: Psycorogue (Ryuki)
The Alternative's sole contract monster is Psycorogue resembling a humanoid cricket which had the ability to transform into a motorcycle named Psycoroader through the use of the Wheel Vent Advent Card and during the Alternatives' Final Vent Dead End. This Mirror Monster had an opposite color scheme to its corresponding Rider, having white armor with black accents. Its name is a portmanteau of the two words, psycho and koorogi, which is Japanese for "cricket".
Because they were designed by Kagawa and not by Shiro Kanzaki, the Alternatives' Advent Cards differ from the ones used by the Kamen Riders. The terminals and images are printed crosswise, having the inscription 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.
Slash Visor (スラッシュバイザー Surasshu Baizā): The Alternative system's card reader is mounted on the wielder's right forearm, with a female voice unlike the male voice used by the Kamen Riders's Visors. Unlike the regular Visors, the Alternatives swiped their Advent Cards across their Visors (much like the Rouzers used in Kamen Rider Blade), which burned up with jet-blue flames and disappeared at the card's scanning.
- Advent (AP: 6500): Summons Psycorogue.
- Sword Vent (AP: 2000): Conjures the Slash Dagger.
- Accele Vent (AP: 2500): Increases Alternative's movement speed.
- Wheel Vent (AP: 4500): Transforms Psycorogue into Psycoroader.
- Final Vent (AP: 8000): Executes Dead End. Psycorogue transforms into a motorcycle, then Alternative and motorcycle spin-out faster and faster until they ram into the opponent. Only Alternative Zero performed his Final Vent. Alternative was killed before performing it.
