The King of Braves GaoGaiGar: Mikoto Utsugi

She's Gai Shishioh's girlfriend and an member of 3G (Gutsy Geoid Guard) who is responsible for launching the GaoMachines, activating the Final Fusion program and sending out equipment like the Dividing Driver. She is also a crucial part of the activation process of the Goldion Hammer, doing the final "relieving" of its safety device for Gai to take down powerful enemies without relying on GaoGaiGar's Hell and Heaven finishing move due to putting too much stress to not only the GaoMachines but himself too since he's part cyborg thanks to the G-Stone. She got a kind hearted personality but always worried about Gai because he always pushed himself beyond his limits in battle and nearly killed himself at times but has remained loyally at Gai's side through his reconstruction and rehabilitation after certain hard fights he was in. This is from Episodes 18 and 19 where she and many members of 3G got infected by a Zonder parasitic micromachine that make them go crazy and start wrecking things.
