The Transformation Gun Whale Change Gun (変身銃ホエールチェンジガン Henshin jū Hoēru Chenji Gan) is a weapon which can transform its user into Zyuoh Whale. Little is known about this weapon at this time except that it has five modes: transformation, final attack, summon, cube transformation, and final combination.
The Whale Change Gun was born from the Earth's power during an attack on Earth by a powerful monster in ancient times. A brave Zyuman by the name of Cetus used it to transform into the first Zyuoh Whale and defeated the monster, while also awakening a massive Zyuoh Cube known as Cube Whale. Upon the creation of Zyuland, the Whale Change Gun was later sealed into a golden cube known as the Great King's Credential (大王者の資格 Dai Ōja no shikaku) and formed the core of the Link Cube.
In present times, Bangray, a Megabeast Hunter, came down to Earth, knowing of the existence of Cube Whale and thus wanted to hunt it down by taking control of the Great King's Credential. Soon, he caught the attention of Captain Marvelous, who also wanted to take the Great King's Credential, which he regarded as treasure. Marvelous later encountered the Zyuohgers, who led him to the Link Cube, with a revived Dorobozu spying on them in secret. There, Marvelous found the Great King's Credential hidden within the Link Cube. The Great King's Credential transformed into the Whale Change Gun, which broadcast a message from Cetus about the history of Zyuland. However, thanks to Dorobozu, Bangray was able to find them as well. As Marvelous, Bangray, and the Zyuohgers fought one another, Marvelous gained possession of the Whale Change Gun and tries to escape.
When Marvelous later felt that Yamato was worthy enough to use the Whale Change Gun, he entrusted the weapon to Yamato. The Whale Change Gun immediately transferred Cetus' Zyuman Power into Yamato, with Yamato seeing Cetus' spirit giving his approval.
When Yamato was disarmed of the Whale Change Gun by Azald, Bud took it upon himself to recover and wield the weapon originally used by the ancient Great King. Performing the Deep Lock, Bud succeeded in freezing Azald in place just before he passed out as his transformation negated. However, Azald, broke free soon after and, having remembered who he was, assumed his true form as it was finally revealed that he was the monster that Cetus and defeated ages ago as he ferociously defeated the remaining Zyuohgers.
After the Zyuohgers finally destroyed Ginis, defeating the Deathgalien once and for all, Yamato returned the Whale Change Gun along with the six King's Credentials to the Link Cube, which had the unexpected effect of the Link Cube merging the two worlds into one, restoring the world to the union of humans and Zyumans prior to the Link Cube.
Super Sentai Strongest Battle
Fighting in the Super Sentai Strongest Battle on the planet Nemesis, Yamato, while single-handedly engaging three members of the Land, Sea, Air Team, became Zyuoh Whale to appropriately fight VulShark, beating him back with the Whale Change Gun. Yamato then performed the Zyuoh Final to defeat VulShark along with GingaGreen and GaoRed.
Later, while fighting alongside Gokai Red to free who they believed to be Takaharu Igasaki from the Gaisorg armor, Yamato assumed the form of Zyuoh Whale to fight Gaisorg. After Gaisorg was worn down by Marvelous' successive Gokai Changes of MagiRed and DynaRed, Yamato used the Zyuoh Final to defeat Gaisorg, revealing Stinger inside.
