Gaoranger vs. Super Sentai
Years later, Yuuji 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 OhBlue powers are later used by Joe Gibken via the Ranger Keys.
Super Hero Taisen
Yuuji, alongside his team (bar KingRanger), 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.
The OhBlue Ranger Key (オーブルーレンジャーキー ŌBurū Renjā Kī?) is Yuuji'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 OhBlue Ranger Key was mainly used by Joe Gibken (Gokai Blue), who used it to fight as OhBlue.
- When the Gokaigers became the Ohrangers while fighting Action Commander Stargul.
- When the Gokaigers became the Ohrangers while fighting Basco's Ranger Key Clones.
After Zangyack were finally defeated, the Gokaigers gave the Ranger Keys back to their rightful owners. It is presumed that Yuuji received his key and became OhBlue once more.
