|~ Blue Flash|
Bun (ブン) is the Blue Flash of the Flashmen.
Bun frequently makes sarcastic quips. As the youngest member of the team, he yearns most to find his parents.
He gained speed and agility on the deserts of the Blue Star planet. He learned survival skills on the harsh planet of Blue Star, such as surviving 30 days on one cup of water and how to climb walls.
Bun and his team joined up with the other nine Sentai to stand behind the newest Sentai, the Turborangers, as they faced off against the Hundred Boma Tribes.
Gaoranger vs. Super Sentai
Years later, Bun fought alongside not only his own team, but every single Sentai ranger in existence, against the Empire of Zangyack when it attacked the Earth in the Great Legend War. After fighting against hundreds of Gormin]] and their Zgormin commanders. Kaijou noticed the fleet moving towards them, he gathered all the Rangers together and gave them the order to sacrifice their powers to wipe out the first invasion's armada. The Blue Flash powers are later used by Joe Gibken via the Ranger Keys.
