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 DenziBlue powers are later utilised by Joe Gibken via the Ranger Keys.

After the Legend War, Daigoro encountered the Gokaigers twice during their own journey.

After the Gokaigers and Gavan's battle ended, A mysterious voice asked that he, Retsu, and Shirou Akebono transform one last time. Don Dogoier and Joe gave Daigoro and Shirou their respective Ranger Keys. After they were handed the Keys, the three transformed and roll called. After that, Gai Ikari began hounding them for autographs.

Ranger Key
The DenziBlue Ranger Key (デンジブルーレンジャーキー) is Daigoro Oume'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 DenziBlue Ranger Key was mainly used by Joe Gibken (Gokai Blue), who used it to fight as DenziBlue.
 * When the Gokaigers became the Denzimen while fighting the Sneak Brothers.
 * Alongside Ahim (DenziPink) against the Gormin, thwarting Zaien's attempt to kidnap humans for mass-producing Barizorgs.
 * Alongside Gai (Go-On Gold), using their boxing powers against the Gormin in the Makuu Prison.

The Denziman 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 Denziman keys were defeated by Super Gosei Blue.

When Daigoro and Shirou Akebono (Battle Kenya) were informed by the Gokaigers that Space Sheriff Gavan had been captured and taken to Makuu Space, they suggested that they use their Ranger Keys to open the gateway to Makuu Space. Joe used the DenziBlue key, while Don (Gokai Green) used the Battle Kenya key alongside him to open the gateway. After Gavan was rescued, a mysterious voice requested that the three of them (who happened to look alike) transform. Daigoro and Shirou were temporarily given their keys back to transform alongside Gavan.

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