The Gosei Morpher is the morphing device of the Mega Rangers. It is designed after Gosei's Earthly tiki form. The sound activates when Power Cards are inserted into a device when open, then the card's ability when closed. It can also summon various items when they use the Power Cards. In order to tell the device to work, they must say, "Activate!". The Gosei Morpher is voiced by Geoff Dolan, who also voices the team's mentor, Gosei.
