Yousuke Shima (島 洋介 Shima Yōsuke) is DynaBlue (ダイナブルー Daina Burū) of the Dynamen.
He is from Ishigaki Island. An 18 year old swimmer and surfer who dreams of inventing artificial gills to allow people to breathe underwater and enjoy water life in all of its glory. Has extensive knowledge of sea-life. Despises losing, always wanting to make up for failures he is responsible for. His exclusive vehicles are the Surf Jet and the Attack Board.
Gaoranger vs. Super Sentai
Years later, Shima 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 DynaBlue powers are later utilized by Joe Gibken via the Ranger Keys.

The DynaBlue Ranger Key (ダイナブルーレンジャーキー Daina Burū Renjā Kī) is Yousuke Shima'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 DynaBlue Ranger Key was mainly used by Joe Gibken (Gokai Blue), who used it to fight as DynaBlue.
- When the Gokaigers became the Dynamen while fighting Deratsueigar of the Zangyack Imperial Guard.
- When the Gokaigers became the Dynamen while fighting a Zangyack force led by Insarn and Barizorg.
- When the Gokaigers became the Dynamen in order to use the New Super Dynamite attack against Action Commander Shieldon in a vein attempt to penetrate his shield.
The Dynaman 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 Dynaman keys were defeated by Gokai Red.
After Zangyack were finally defeated, the Gokaigers gave the Ranger Keys back to their rightful owners. Yousuke received his key and became DynaBlue once more.
