The Shika Inves is a Berseker Inves that was summoned by Kota via his Ichigo Lockseed for an Inves Game against Baron. Due to the Shika Inves having its human adult size, it managed to win against Baron's three Inves Warriors and nearly wins the duel. Unfortunately, Peko disarmed his Lockseed at the moment of victory, making the Shika Inves break out into the real world and starts wrecking the city, as well as making the fleeing crowds kick around the dropped Ichigo Lockseed like it was a hockey puck.
Eventually, the Shika Inves find the Ichigo Lockseed before Kota could grab it to send the Shika Inves back home and eats it, triggering its evolution into the Evolved Shika Inves (進化シカインベス) to easily beat Gaim until Kaito gives Gaim the Pine Lockseed, allowing Gaim to transform into Gaim Pine Arms and destroys it with the Iron Breaker finisher.
A second one evolved from a Elementary Inves when it ate a Donguri Lockseed thrown down by Zangetsu to fight Kota. Gaim defeats it with the Musou Saber while in Pine Arms.
Another one has summoned by Kamen Rider Bravo along with horde of Elementary Inves. Later it was destroyed by Gaim's Suika Arms Odama Mode.
