One of [[Kamen Rider OOO]]'s combos, accessed via the Orca (Shachi), Eel (Unagi), and Octopus (Tako) Core Medals.

OOO now excels in [[underwater]] [[battle|battles]] and gains the ability to liquefy his body like [[Kamen Rider BLACK RX]] as the Bio Rider. He is armed with the Denki Unagi Whips which enable [[electricity|electrically]] charged attacks, the most powerful being the Voltarm Whip. The Tako Legs allow OOO Shauta to climb walls with their suction cup-like abilities and can split apart for a barrage of hits. Although Shauta is better well-suited for underwater combat, it's also very weaker than the other combos due to its punching and kicking power, but it has fantastic flexibility. He can also perform an echolocation via the Shachi Head.

His Scanning Charge is the Octo Banish, where OOO liquefies his lower body to propel himself upward, then use the Unagi Whips to drag the opponent upward while OOO goes back down using the Tako Legs to form a [[drill]] to burst through the opponent.
