Legend Rider Lockseeds
Based on Riders and other characters from past series, Legend Rider Lockseeds (レジェンドライダーロックシード) contain the power of the character they are based on, but don't offer much of that form's abilities. They debuted in the Movie War film, Kamen Rider × Kamen Rider Gaim & Wizard: The Fateful Sengoku Movie Battle, where four such Lockseeds were used by Gaim, Baron, Ryugen, and Zangetsu. In-universe, these Lockseeds were created when the transformation items belonging to four of the most recently defeated Bujin Riders (Joker Memory, Taka Medal, Rocket Switch, Flame Ring) were fused with Helheim Fruit. What ultimately became of those Lockseeds is not shown in the movie.

Legend Rider Lockseeds reappeared in Heisei Rider vs. Showa Rider: Kamen Rider Taisen feat. Super Sentai, which introduced the Heisei Rider Lockseed and Showa Rider Lockseed, special Lockseeds that could channel the powers of the individual Legend Rider Lockseeds, which had been created when the various Heisei Riders and Showa Riders were each defeated and transported to the Badan Empire's lair, where they were turned into Lockseeds, until they were restored to normal by the actions of ZX and Gaim.

Like normal Lockseeds, they contain images, with the core image depicting the Rider's Transformation Belt while the image on the backside of the lid usually depicts the item which is inserted to commence transformation, or something else related to the Rider, denoting them as the ingredients that make the represented Rider.
