Bun (Flashman)

"Blue Flash!"

Bun (ブン) is the Blue Flash of the Flashmen.

Flashman
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 frequently makes sarcastic quips. As the youngest member of the team, he yearns most to find his parents.

Turboranger
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.

Gokaiger
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.

Super Hero Taisen
Bun, alongside his team, among the majority of the Super Sentai heroes, was caught up in the "Super Hero Taisen" incident which eventually resulted in the Super Sentai teams and Kamen Riders joining forces to defeat both Dai-Zangyack and Dai-Shocker.

Super Hero Taisen Z
The Flashmen are seen alongside the Dekarangers, standing behind Space Sheriff Gavan Type G and Kamen Riders Fourze, Meteor, Decade and Super-1 as the three forces of super heroes confront Space Shocker.

Ranger Key
The Blue Flash Ranger Key (ブルーフラッシュレンジャーキー) is Bun's personal Ranger Key and what became of his powers after he along with the rest of the 34 Super Sentai sacrificed their powers to end the Great Legend War.

This key along with the majority of the Ranger Keys were collected by the Red Pirates and later used by the Gokaigers. The Blue Flash Ranger Key was mainly used by Joe Gibken (Gokai Blue), who used it to fight as Blue Flash.
 * When the Gokaigers became the Flashmen while fighting Action Commander Regaeru.

After Zangyack were finally defeated, the Gokaigers gave the Ranger Keys back to their rightful owners. It is presumed that Bun received his key and became Blue Flash once more.
