Elementary Inves (Red)

Advanced Inves typically start out as Elementary Inves (初級インベス Shokyū Inbesu), human-sized Inves summoned by Lockseeds from the Helheim Forest during an Inves Game to battle against the Armored Riders (opponent) or the opponents' Inves. In a normal Inves Game, they are about the same size as a small child, but when summoned by an Armored Rider or through a jailbroken Lockseed, they will retain their full size. If they break out of an Inves Game, they will go into a rampage and start attacking until they are either sent back into the Helheim Forest or killed. When they eat a mature Lockseed, they will evolve into a stronger, animal-based form called a Advanced State.

Advanced Inves (Yagi)

Advanced Inves (上級インベス Jōkyū Inbesu) are human-sized Inves summoned by Lockseeds from the Helheim Forest during an Inves Game to battle against the Armored Riders (opponent) or the opponents' Inves, though only when someone uses an A-Ranked Lockseed. Unlike their lesser Elementary counterparts, Advanced Inves retain their human size while in a Inves Game, as well as being themed after a specific animal. They are also much stronger than their previous evolution, prompting the need of a Armored Rider if a rogue Advanced Inves is around.

While wild Advanced Inves are somewhat uncommon, this kind of Inves can also be created by having a Elementary Inves feed on a Lockseed, where they evolve into a Advanced Inves that shares their color. Advanced Inves can also be created when a human eats a unripened fruit.
