Lockseeds

Lockseeds (ロックシード) are mysterious devices that are the source of the Armored Riders' powers. They all have powers associated with fruits, seeds, berries, and nuts. Lockseeds can grow on trees in the Helheim Forest, assuming the shape of a flower first.

The Inves love Lockseed flowers, regarding them as their favorite food. However, if an Inves consumes a mature Lockseed, it assumes its Berserker State, and if it consumes another mature Lockseed, then that Inves will evolve into its Evolved State.

In Inves Games, people use mature Lockseeds to summon Inves to do battle. When a person wearing a Sengoku/Genesis Driver picks Lockseed flowers, they will quickly turn into mature Lockseeds. When Inves Games starts, the Lockseeds say "Battle, Start!". After Inves Games battle, these Lockseeds can say "You Win!" or "You Lose..." depending on the results of battle. After a victory, the toy Lockseed can say "Rank Up!" which has yet to be used in the show.

In the Hyper Battle DVD, the Lockseeds were rusted, preventing transformations and Inves summoning.

If an Armored Rider summons an Inves in a battle, then they will be fully materialized in the real world, however if a Next Generation Rider summons an Inves, one Lockseed can call in three at a time. If one manages to jailbreak a Lockseed (though Sid had to show how to do so), they can summon fully materialized Inves as well without being an Armored Rider, although there is a chance for the Lockseed to malfunction.

Inves
The Inves love Lockseeds, regarding them as their favorite food. In the Helheim Forest, Inves eat immature Lockseeds by eating the core of the Lockseed and throwing the rest of it away immediately afterwards when they are done.

Immature Lockseeds


Immature Lockseeds, also known as the fruit of Helheim (ヘルヘイムの果実), are Lockseeds in their immature state that grow in the Helheim Forest. They normally look like fruit, however if anyone wearing a Sengoku Driver picks them they will turn into mature Lockseeds. The Inves love both types of Lockseeds, regarding them as their favorite and only food, and will attempt to protect them if they are picked.

People who don't wear a Driver when entering Helheim or/and nearby the place where the Helheim crack portal was opened out of nowhere also seem tempted to eat Immature Lockseeds, and it takes outside help to make sure they don't eat it.

When a living being does eat a premature Lockseed, be it human or an animal, it quickly rewrites the creature's DNA and minds, as they will turn into an Inves, and in human cases like Ryoji Hase did, into an Inves in a Berserker State, where the Yggdrasill higher-ups then calls them "Category H" Inves; Inves that were formerly human. Confirmed Category H Inves are: However, it can be used as an alternative food source if a person holding a Lockseed inserts it in a Sengoku Driver like Kouta Kazuraba and Takatora Kureshima who used a Himawari Lockseed as a substitute for food.
 * Yuya Sumii of Team Gaim; devoured an immature Lockseed and mutated into a Byakko Inves. He was unknowingly killed by Armored Rider Gaim.
 * An unnamed maintenance worker; devoured an immature Lockseed and mutated into the Komori Inves (Mutant). He was killed by Armored Riders Gaim and Ryugen.
 * Ryoji Hase of Team Raid Wild; devoured an immature Lockseed and mutated into a Hekija Inves. While Gaim tried to help Ryoji reclaim his humanity, he was murdered by New Generation Rider Sigurd when Gaim could not gather the mental fortitude to slay Ryoji.

Classes
Matured Lockseeds are given ranks, from D to A, but it is unknown if either the number of the Lockseed, the chance of rarity of such a Lockseed being found, or a combination of the two makes the Lockseed's ranking.

A-Classed Lockseeds are normally unbreakable (though they can be devoured by an Inves or destroyed by an Overlord). Give their powerful nature, they are useful for both transformation as an Armored Rider or to summon a high classed Inves. One drawback is that the summoned Inves is in its Berserker State, and if said Inves consumes a Lockseed that summoned it or an entirely different Lockseed, it will evolve into a second form of itself called an Evolved State (進化態).

Beyond the normal variety of Lockseeds, there exists another brand of Lockseed in the form of Lock Vehicle Lockseeds (ロックビークルロックシード). They are indicated by their rougher design and their theme being based on flowers. Once unlocked, the Lock Vehicles will unfold from their Lockseed Modes into their Vehicle Modes, and have the capacity to breach into the Helheim Forest when they hit a certain speed. Due to these Lockseeds being made mainly as a mode of transportation, Lock Vehicle Lockseeds do not have a Lockseed ranking. They are quite rare to appear naturally, as Yggdrasill's mass picking for R&D might have made a hit to the appearance of Lock Vehicle Lockseeds.

Yggdrasill has managed to create fully functional artificial Lockseeds called Energy Lockseeds (エナジーロックシード), more powerful Lockseeds that sacrifices the ability to summon a normal Arms Weapon when used in a Driver, instead summoning a Sonic Arrow. These particular Lockseeds can only be used by a New Generation Rider with a Genesis Driver, though there is a roundabout way Sengoku Driver-wearing Armored Riders can use Energy Lockseeds. In terms of rankings, Energy Lockseeds are given the general rank of Class S, outranking even the more powerful natural Lockseeds. Like A-Classed Lockseeds, they are normally unbreakable, though Rosyuo was able to easily dissolve Sid's Cherry Energy Lockseed with a force-based attack.

 * Sid Lockseed (シドロックシード): Seen in the initial trailer being held by Sid, then later appeared in the series proper. It appears to have an S shape on the front and is colored in black and gold. It is revealed that it can be used in a Lockseed compatible weapon and, if used to shoot/slice through specific Lockseeds, can summon autonomous versions of Lock Vehicles and Suika Arms armors to fight for him.

Inves Games Only

 * Himawari Lockseed (ヒマワリロックシード): This Lockseed is used to summon Elementary Inves to use in Inves Games. Its code is LS-00 and it is Class D. It appears to be a very common Lockseed, being used by Mitsuzane Kureshima, Mai Takatsukasa, Kaito Kumon, and Ryoji Hase with still others being sold by Lock Dealer Sid. Strangely, when opened, the bottom doesn't give any indication of an associated weapon. When not used for an Inves Game, this Lockseed can act like a food supply when attached on the Sengoku Driver. Additionally, the toy version doesn't have any sounds associated with a form either, giving it only the generic Inves Game announcements and Inves sounds.

Legend Rider Lockseeds
Listed as movie sets in some sources, the Legend Rider Lockseeds (レジェンドライダーロックシード) contain the power of a Kamen Rider that they are based on. The first set contains the Double and Wizard Lockseeds, while the second set includes the OOO and Fourze Lockseeds. The Arms of these Lockseeds are based off of the Rider it is based on, but doesn't exactly offer much of that form's abilities.

Like normal Lockseeds they contain images when opened, the inside image depicts 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.

These new armors for the Riders appeared in the Movie War film, Kamen Rider × Kamen Rider Gaim & Wizard: The Fateful Sengoku Movie Battle. These sets were released in December.

Legend Rider Lockseeds later appear in Heisei Rider vs. Showa Rider: Kamen Rider Taisen feat. Super Sentai where they are used by the villainous Kamen Rider Fifteen.

In the Movie War, the Legend Rider Lockseeds were created with the fusion between the transformation items belonging to four of the most recently defeated Bujin Riders (Joker Memory, Taka Medal, Rocket Switch, Flame Ring) and Helheim Fruit. In Kamen Rider Taisen, the Heisei Riders and Showa Riders are turned into Lockseeds when they are defeated, transported to the Badan Empire's lair before they are freed by ZX and Gaim.

When transforming into these Rider Arms, it may also change the user's personality into those of the Rider's. Kamen Rider Zangetsu almost lost grip of his personality while in Fourze Arms.

Portrayal
The voice of the Lockseeds, as well as the Sengoku Driver, Musou Saber and DJ Gun, is provided by Seiji Hiratoko (平床 政治). The Energy Lockseeds, as well as the Genesis Driver and the Sonic Arrow, is provided by Shin-ichiro Miki (三木 眞一郎).

Conception
An interview with Kamen Rider Gaim producer Naomi Takebe in Hyper Hobby revealed the inspiration for the Lockseeds arising in early design meetings, with the sentences “Opening a new world” and “Unlocking potential” in mind. After some research it was decided that locks were the best choice, being something that has never been used in Kamen Rider. This decision was made at a very early point, with Takabe noting that they had no idea what the story was even going to be like then.
