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 Advanced State, and if it consumes yet another mature Lockseed, then that Inves will evolve into its Strengthened Form.

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 an Inves Game starts, the Lockseeds say "Battle, Start!". After an Inves Game, these Lockseeds say "You Win" or "You Lose" depending on the result of the battle. After a victory, the toy Lockseed says "Rank Up!", which has yet to be used in the show.

In the Hyper Battle DVD, the Riders' Lockseeds become rusted, preventing transformations and Inves summoning, however there are ways to to restore them, according to the Woman of the Beginning.

If an Armored Rider summons an Inves in a battle, then they will be fully materialized in the real world, however if a New 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 either outside help or a high level of mental endurance 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 without transforming, allowing the wearer to gain nourishment from Lockseeds without the risk of mutation.
 * 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.

A non-humanoid kaijin type, like Beast Chimera, can survive eating the fruit without any side effects, while a intelligent, humanoid kaijin type like Overlord Demushu has an effect of entering their evolved states.

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 powerful attacks). Given 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 Advanced 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 Strengthened State (強化体).

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 (with the exception of Kurokage Shin and Gaim Yami). 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 (except skilled users of the Suika Lockseed). 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.

Some time after, Gaim was able to obtain another Ichigo Lockseed, which had belonged to Team Invitto until they lost an Inves game to Ryugen, before he appears in the World within the Magic Stone.
 * Suika Lockseed (スイカロックシード): Allows Gaim to transform into Suika Arms, a colossal mecha-like form that is capable of assuming 3 different modes (Yoroi, Odama, and Gyro) and equipped with the Suika Sojinto while in Yoroi Mode. Its code is LS-10 and it is Class A. This Lockseed was originally in possession of Takatora Kureshima until Mitsuzane stole it from him. Another one is achieved, when Kouta got another Suika Lockseed in the Yggdrasill's base in Helheim Forest. After Kouta uses the Suika Lockseed, it loses its color and becomes unresponsive for a certain amount of time. In the toyline, the Suika Lockseed makes the sound of bowling pins being knocked down after its transformation call is announced. Kouta loaned his personal Suika Lockseed to Baron to fight Sigurd during a failed invasion into Yggdrasill, but has yet to get it back, while Ryugen has the one he stole from his brother.
 * Banana Lockseed (バナナロックシード): Allows Gaim to transform into Banana Arms, equipped with the Banaspear. Its code is LS-08 and it is Class A. The Banana Lockseed is normally used by Kamen Rider Baron.

 * Kachidoki Lockseed (カチドキロックシード): Allows Gaim to transform into Kachidoki Arms, equipped with the DJ Gun as his Arms Weapon and the Kachidoki Bata twin flags attached to his back. Its code is KLS-01. Gaim obtained this Lockseed from DJ Sagara, who had created it by first transmutating an orange into a metallic version of one, then into the Kachidoki Lockseed. This Lockseed was temporarily destroyed during his battle with Rosyuo. However, due to Kouta's current status as an Over Lord Inves, he was able to restore it back to its original form. In the toyline, a cheaper variant (candy toy) of the Kachidoki Lockseed is available, which resembles a normal Lockseed, for those unable to purchase a DX Kachidoki Lockseed.
 * Kiwami Lockseed (極(きわみ)ロックシード): A special Lockseed-like key that when activated on the Senyo Joint after it is magically attached to the Sengoku Driver allows Gaim to evolve his Kachidoki Arms into Kiwami Arms, granting him access to every basic Arms Weapon and every weapon with an attachment slot designed for the Lockseeds. Unlike other Lockseeds which announce their names when they are activated, the Kiwami Lockseed announces "Fruits Basket" (フルーツバスケット) when the button that pops out the key portion is pressed. After this Lockseed is inserted into the Kachidoki Lockseed and the key is turned, it announces "Lock Open" (ロックオープン). Its code is LS-$$\infty$$ (LS-Infinity). The Kiwami Lockseed was created from a seed of the Forbidden Fruit that Rosyuo has been heavily guarding, before he gives it to DJ Sagara, which is later given to Kouta by DJ Sagara. The toy version can be used with the Sengoku Driver without the DX Kachidoki Lockseed without the annoucements.

It appears to be a very common low-level 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 (the Joker Memory, a Taka Medal, the Rocket Astroswitch, and the Flame Style Wizard 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, as Kamen Rider Zangetsu almost lost grip of his personality while in Fourze Arms. The same case can go for when the Showa Lockseed or the Heisei Lockseed is used, as Kamen Rider Gaim announced out "Rider Kick" when he did his finishing attack in 1 Arms, when he normally doesn't say anything when doing a finishing attack.

In addition, Legend Rider Lockseeds based on non-main forms will announce its form name when activated/unlocked instead of its Rider name and usually has the same style as its main form Legend Rider Lockseed with a few exceptions (Ryuki/Ryuki Survive, Faiz/Faiz Blaster, and Fourze/Fourze Cosmic).

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.
