The Knight Power Invocation Device Leon Cellular (ナイトパワー解放器レオンセルラー Naito Pawā Kaihōki Reon Serurā) is Gosei Knight's transformation device that first appeared in Epic 17 of Tensou Sentai Goseiger. This transformation device has a number pad so Gosei Knight can perform various Tensou Techniques by pressing a 3-digit number combination, then press the red "Enter" button, call out "Tensou!" and close up the Leon Cellular. Just like the Tensouder, it is voice activated.

At the climax of the Legend War, the Leon Cellular as a transformation device was made redundant when Gosei Knight sacrificed his powers with the rest of the first 34 Super Sentai to destroy the invasion force of the Space Empire Zangyack. Resurfacing as a Ranger Key, the power of Gosei Knight would be used by the Gokaigers to assume the form via the Gokai Change. Ultimately, the Gokaigers returned their borrowed powers to their rightful owners after overthrowing Zangyack.


Here are the cards that can be inserted and the 3-digit number code in order to activate.
