Advanced Inves (上級ロイミュード 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.
