Kamen Rider

The Kamen Rider Series (仮面ライダーシリーズ) is a popular tokusatsu series and a sister series of the Super Sentai series. The two series make up the Super Hero Time programming block on TV Asahi. Several actors in Super Sentai have also appeared in Kamen Rider.

Super Sentai
Kamen Rider has several shoutouts and references to Super Sentai as well as a crossover.

Kamen Rider is mentioned in JAKQ Dengekitai vs. Goranger. It is said that Kamen Rider V3 is fighting Baron Iron Mask and Kamen Rider Amazon is fighting in South America.

Super Sentai and Kamen Rider movies are often billed together. On one such instance, in 1994, the two movies were linked together. Super Sentai World and Kamen Rider World were shown as a triple feature alongside a Metal Heroes movie which did not share this connection. Both Super Sentai World and Kamen Rider World featured the supporting characters, Masato, played by Shiro Izumi of Changeman and Zyuranger fame, and his younger sister Ayumi.

The Hyper Battle Video Kamen Rider Ryuki: Ryuki vs Kamen Rider Agito, sees Shinji Kido having a dream where, as Kamen Rider Ryuki, he joins up with Kamen Riders Knight, Zolda, and Ouja. They then team up with Agito. The riders act out of character in the dream, more like a Super Sentai team.

The Abaranger movie, Bakuryuu Sentai Abaranger: Abare Summer is Freezing!, included a reference to the Kamen Rider movie it was double-billed with, Kamen Rider 555: Paradise Lost (mostly as a breaking the fourth-wall joke), where Disciple of Dawn Lije tells Visionary Messenger Voffa there isn't enough time to use his Giganoid with the movie over.

Episodes of Kamen Rider Decade on July 12 and July 19, 2009, as well as Act 21 of Samurai Sentai Shinkenger, featured a crossover between the two series.

Kaizoku Sentai Gokaiger and Kamen Rider Decade are similar in that both feature warriors changing into those of the past, they are both anniversey seasons, and both feature one of their movies being a big gathering of all heroes of their respective shows.

A crossover movie between Super Sentai and Kamen Rider has been announced, Kamen Rider vs. Super Sentai: Super Hero Taisen. The movie will feature Gokaiger and Decade as the lead, with Go-Busters and Fourze having a more minor role.

Aside from on-screen crossovers, Kamen Riders and Super Sentai have joined forces numerous times in stage shows over the years.

Actors who have appeared in both franchises
Numerous actors have had roles for episodes and/or films in both the Super Sentai and Kamen Rider series. Note this list does not included actors who have played Super Sentai characters in a crossover with Kamen Rider, such as Kamen Rider Decade: Shinkenger World and Super Hero Taisen. For example, Yui Koike, who plays Ahim de Famille in Kaizoku Sentai Gokaiger and in Super Hero Taisen is counted due to her role in Kamen Rider W, while her co-star, Ryota Ozawa, who plays Captain Marvelous in Kaizoku Sentai Gokaiger and Super Hero Taisen, is not counted as he has not played an original Kamen Rider character.

Adaptation
When Saban acquired the rights to create a adaptation of Kamen Rider similar to Power Rangers, they created "Masked Rider". Masked Rider was introduced in a three part episode of Power Rangers that paved the way for Masked Rider. In 1996, Marvel Comics published a one shot issue of Masked Rider, which was the last time the character teamed up with the Power Rangers.

In 2009, another American Kamen Rider adaptation was broadcast, Kamen Rider Dragon Knight. However, this adaptation had no connection with Power Rangers, being conducted by Adness Entertainment.

Recently Saban has registered a trademark for "Power Rider", which has led some to believe that a new Kamen Rider adaptation is coming. Most people speculate that it will be Kamen Rider Decade as he and Samurai Sentai Shinkenger had a crossover, and Shinkenger's PR counterpart; Power Rangers Samurai is currently airing.
