Ryuuta Nanbara

Ryuuta Nanbara is a former marine sports enthusiast and one of the more playful members of the Bioman team. Often serving as comic relief, he balances his lighthearted personality with real tactical skill and a talent for stealth.

Ryuuta is especially effective at infiltration and misdirection. He once pretends to be a thief to slip into one of Gear's operations, and he is often the one sent to rappel down buildings, sneak into guarded rooms, or enter dangerous places the hard way.

As Blue Three, Ryuuta uses aquatic athleticism, agility, and clever tricks to support the team. His abilities include Screw Kick, Flying Cutter, Super Sky Diving, and Choudenshi Ear, which allows him to hear the humming of disguised Mecha Clones.
