Lockseeds

Lockseeds are mysterious devices that are the source of the Kamen 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 a Feudalite 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 a Inves Game starts, the Lockseeds say "Battle, Start!". After a 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 Faye.

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

Inves[]

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 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 the forest or/and nearby the place where the Inves 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 Inves, and in human cases like Akira Hase, into a Inves in a Berserker State, where the S.C.P. Corporation higher-ups then calls them "Category H" Inves; Inves that were formerly human. Confirmed Category H Inves are:

Yuya of Team Armor Warrior; devoured an immature Lockseed and mutated into a Tigro. He was unknowingly killed by Kamen Rider Armor Warrior.
An unnamed maintenance worker; devoured an immature Lockseed and mutated into the Fang Bat. He was killed by Kamen Riders Armor Warrior and Dragon Defender.
Akira Hase of Team Pine; devoured an immature Lockseed and mutated into a Drakken. While Armor Warrior tried to help Akira reclaim his humanity, he was supposedly murdered by Kamen Rider Lock Dealer Sigurd when Armor Warrior 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.

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.

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 Inves or destroyed by powerful attacks). Given their powerful nature, they are useful for both transformation as an Kamen 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.

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 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 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 Kamen Rider Dark Armor Warrior). These particular Lockseeds can only be used by an New Generation Rider with an Genesis Driver, though there is a roundabout way Sengoku Driver-wearing Kamen 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 Scott's Cherry Energy Lockseed with a force-based attack.
