Lockseeds

Lockseeds 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 Feudal Forest, assuming the shape of a flower first.

The Feudalites love Lockseed flowers, regarding them as their favorite food. However, if a Feudalite consumes a mature Lockseed, it assumes its Advanced State, and if it consumes yet another mature Lockseed, then that Feudalite will evolve into its Strengthened Form.

In Feudalite Games, people use mature Lockseeds to summon Feudalites to do battle. When a person wearing a Feudal/Energy Driver picks Lockseed flowers, they will quickly turn into mature Lockseeds. When a Feudalite Game starts, the Lockseeds say "Battle, Start!". After a Feudalite 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 Faye.

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

Feudalites
The Feudalites love Lockseeds, regarding them as their favorite food. In the Feudal Forest, Feudalites 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 the forest, are Lockseeds in their immature state that grow in the Feudal Forest. They normally look like fruit, however if anyone wearing a Feudal Driver picks them they will turn into mature Lockseeds. The Feudalites 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 the forest or/and nearby the place where the Feudal 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 a Feudalite, and in human cases like Akira Tao, into a Feudalite in a Berserker State, where the S.C.P. higher-ups then calls them "Category H" Feudalites; Feudalites that were formerly human. Confirmed Category H Feudalites are: However, it can be used as an alternative food source if a person holding a Lockseed inserts it in a Feudal Driver without transforming, allowing the wearer to gain nourishment from Lockseeds without the risk of mutation.
 * Yuya of Team Orange; devoured an immature Lockseed and mutated into a Tigro. He was unknowingly killed by Armored Rider Orange.
 * An unnamed maintenance worker; devoured an immature Lockseed and mutated into the Fang Bat. He was killed by Armored Riders Orange and Drago.
 * Akira Tao of Team Ninjetti; devoured an immature Lockseed and mutated into a Drakken. While Orange tried to help Akira reclaim his humanity, he was supposedly murdered by Energy Rider Cherry when Orange could not gather the mental fortitude to slay Akira. It is later revealed that Revo had saved Akira just before he could be killed, and he was ableto restore him to normal.

A non-humanoid monster type, like Beast Lion, can survive eating the fruit without any side effects, while a intelligent, humanoid monster 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 a Feudalite 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 Feudalite. One drawback is that the summoned Feudalite is in its Advanced State, and if said Feudalite consumes a Lockseed that summoned it or an entirely different Lockseed, it will evolve into a second form of itself called an Strengthened State.

Beyond the normal variety of Lockseeds, there exists another brand of Lockseed in the form of Lock Vehicle Lockseeds. 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 Feudal 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 S.C.P's mass picking for R&D might have made a hit to the appearance of Lock Vehicle Lockseeds.

S.C.P. has managed to create fully functional artificial Lockseeds called Energy Lockseeds, 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 Ninjetti and Dark Rider Samurai). These particular Lockseeds can only be used by an Energy Rider with an Energy Driver, though there is a roundabout way Feudal 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 Melon Walker Lockseed). Like A-Classed Lockseeds, they are normally unbreakable, though Ryuso was able to easily dissolve Aaron's Cherry Energy Lockseed with a force-based attack.

Some time after, Orange was able to obtain another Strawberry Lockseed, which had belonged to Team Viking until they lost a Feudalite game to Drago, before he appears in the World within the Magic Stone.

Its code is LS-10 and it is Class A. This Lockseed was originally in possession of Allen Stephenson until Luke stole it from him. Another one is achieved, when Dylan got another Melon Walker Lockseed in the S.C.P's base in the Feudal Forest. After Dylan uses the Melon Walker Lockseed, it loses its color and becomes unresponsive for a certain amount of time. Dylan loaned his personal Melon Walker Lockseed to Bana to fight Cherry during a failed invasion into S.C.P, but has yet to get it back, while Drago has the one he stole from his friend.

Orange obtained this Lockseed from DJ Revo, who had created it by first transmutating an orange into a metallic version of one, then into the Shogun Lockseed. This Lockseed was temporarily destroyed during his battle with Ryuso. However, due to Dylan's current status as an Overlord, he was able to restore it back to its original form.
 * Ultimate Lockseed: A special Lockseed-like key that when activated on the Ultra Joint after it is magically attached to the Feudal Driver allows Orange to evolve his Shogun Arms to become Feudal Rider Ultimatum, granting him access to all thirteen basic Arms Weapons, all three weapons with an attachment slot for the Lockseeds, and the Ninja Super Staff. Its code is LS-$$\infty$$ (LS-Infinity). The Ultimate Lockseed was created from a seed of the Forbidden Fruit that Ryuso has been heavily guarding, before he gives it to DJ Revo, which is later given to Dylan by DJ Revo. The toy version can be used with the Feudal Driver without the DX Shogun Lockseed without the annoucements.
 * Fresh Orange Lockseed: Allows Orange to transform into Fresh Orange Arms, equipped with twin Orange Slicers. Its code is LS-07, the same as the original Orange Lockseed, since this lockseed is actually the original Orange Lockseed.

Despite being used by Kouta, he always returns it to Mitsuzane after the battle. However, Mitsuzane has yet to use it by himself. According to Micchy in the final episode, his Budou Lockseed is the last Lockseed left, his Suika Lockseed's location is currently unknown.

Kamen Rider Gridon's Lockseeds

 * Donguri Lockseed (ドングリロックシード): Allows Gridon to transform into Donguri Arms, equipped with the Donkachi. Its code is LS-03 and it is Class B. Hideyasu has lost his first Donguri Lockseed to Team Gaim after he and Ryoji had beaten Kaito, and had to buy another one from Sid, and lost that one to Bravo, which was most likely devoured by the Inves that became the Evolved Inoshishi Inves. He obtains another one sometime before the Lockseed Collecting Christmas Game. Hideyasu's Lockseed and Sengoku Driver are destroyed by Knuckle and Marika.
 * A Donguri Lockseed was modified by Oren Pierre Alfonzo, bearing his likeness inside.

It originally belonged to Sonomura of Team Red Hot who had received the last Sengoku Driver from Sid.

This is the only Energy Lockseed which is red in color, unlike the usual Energy Lockseeds, which are colored blue.

 * 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.

Kamen Rider Marika's Lockseeds

Kamen Rider Tyrant's Lockseeds

 * Dragon Fruits Energy Lockseed (ドラゴンフルーツエナジーロックシード): Allows Tyrant to transform into Dragon Energy Arms. Its code is ELS-PROTO. Unlike the usual Energy Lockseeds, which are colored blue, this Energy Lockseed is actually a prototype, as its code suggests, which is in red color. It is given to Alfred by Ryoma Sengoku. However, this lockseed possesses Helheim powers which turns Alfred into an Over Lord Inves (Tyrant). It is later destroyed along with his Genesis Driver and Alfred (as Over Lord) when subjected to a Rider Kick by Baron in Ringo Arms.

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 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.Unlike regular lockseeds these ones have no codes or classes.

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.
