"Break Limit!! Go-On Gold!"
Hiroto Sutou (須塔 大翔 Sutō Hiroto) is Go-On Gold (ゴーオンゴールド Gōon Gōrudo) of the Go-On Wings. He later came to be identified with the Go-Ongers as well. Nicknamed the "Philosopher," he is the cool and aloof leader of the Go-On Wings.
He is amazing in combat. His fighting styles are boxing and kickboxing. He possesses an ESPer ability that allows him to sense when danger is near. He is part of the Go-On Wings, a two-man team composed of the Sutou siblings, chosen by the Wing Clan Engines and brought to the Machine World to become a elite fighting force before the Go-Onger team came to be. However, it is due to their training that he and his younger sister, Miu Sutou, see the Go-Ongers as being too inexperienced to protect the Earth from Barbaric Machine Clan Gaiark.
His seemingly cold exterior belies his fiery passion; he tells the Ancient Engines that, like them and like the Go-Ongers and his sister, he will put his life on the line to protect those that he cares about. Because of this, and a separate incident which saw him care for a Wameikle from Stormy World, the Go-Ongers tab him as their "father." Hiroto, however, is not amused in the least by the reference, unlike Renn Kousaka, who enjoys being the Go-Ongers' "mother." During the Christmas incident, Hiroto, with encouragement from Saki Rouyama, manages to overcome his deeply-seated fear of ghosts.
After transforming into Go-On Gold, Hiroto says "Break the Edge!! Go-On Gold" (ブレイク限界！！ゴーオンゴールド Bureiku Genkai!! Gōon Gōrudo?). With the Rocket Dagger, he can perform the attacks "Burning Dagger," "Lightning Dagger," "Shining Dagger," "Freezing Dagger," and "Full-Power Dagger."
