|This article is about a/an changer in Tensou Sentai Goseiger.|
The Gosei Power Releasement Vessel Tensouder (ゴセイパワー解放器テンソウダー Gosei Pawā Kaihōki Tensōdā) is a transformation device that the Goseigers used in the Tensou Sentai Goseiger series. It is voice activated by inserting the Gosei Cards to the device, saying "Gotcha" when open, then the card's ability when closed. It can also summon various items when they use the Gosei Cards. In order to tell the device to work, they must say, "Tensou!" The Tensouder is voiced by Ikuya Sawaki, who also voices the series' narrator and the team's mentor, Master Head.
The Goseigers call "Change Card, Tensou!" when to transform. Once the Change card inserted, the Tensouder snaps shut while saying, "Change, Goseiger!" and the transformation begins.
