- "Green Flash!"
- ―Green Flash's roll call[src]
Dai gained great strength training on the rocky Green Star, enduring the most physical pain compared to his team mates. He made friends with boxer Ryuu Wakakusa, who further trained him in his boxing abilities. He arms himself with brass knuckles. Although he has a cold exterior, Dai is actually a very warm and charming person. He has a weak spot for women, loves nature and ramen. He befriended the teenage Sumire, who had actually died some years back and had been contacting Dai through telepathy.
Gaoranger vs. Super Sentai
Green Flash is among the Sentai warriors seen in clips when Gouki (GingaBlue) lectured Soutarou Ushigome (GaoBlack) about the past Sentai strong warriors, humbly claiming to not be nearly as strong as they are.
Years later, Dai 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. Akarenger 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 Green Flash powers are later used by Don Dogoier via the Ranger Keys.

The Green Flash Ranger Key (グリーンフラッシュレンジャーキー Gurīn Furasshu Renjā Kī) is Dai'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 Green Flash Ranger Key was mainly used by Don Dogoier (Gokai Green), who used it to fight as Green Flash. It was also used by Ahim de Famille (Gokai Pink) on two occasions.
- While fighting against Action Commander Uorlian on his own.
- When the Gokaigers became the Flashmen while fighting Action Commander Regaeru.
- Ahim first became Green Flash part of an all-green change to defeat a duo of Dogormin. She did a boxing combo attack with Marvelous (DenziGreen).
- Ahim also became Green Flash as part of a Gokai Change combo of the last five teams whose greater powers the Gokaigers acquired, while fighting Insarn.
The Flashman keys, along with all the Ranger Keys of the first 33 Super Sentai, were briefly taken by the Black Cross King and turned into Ranger puppets that were fought by the Gokaigers and the Goseigers. The puppet Flashmen fired their Rolling Vulcan alongside the Changemen, Maskmen, Livemen, and Turborangers, only to be swiftly defeated by the individual finisher attacks of the Gokaigers and Goseigers as they emerged from the resulting fireball.
After Zangyack were finally defeated, the Gokaigers gave the Ranger Keys back to their rightful owners. Dai received his key and became Green Flash once more.
