Prana (プラナ Purana), known as Plana in the English dub of Yu-Gi-Oh! The Dark Side of Dimensions, is an almighty power wielded by Aigami, Sera, Mani and many other unnamed characters. It is described as the ability to bend reality to the user's will and to create a world without evil or fear. According to Shadi, it was bestowed upon Aigami's group when Atem departed for the afterlife. However, should the pharaoh ever return, they will lose the Plana forever, which ultimately drives Aigami to attempt to kill Yugi.

The power is a "one time deal", as opposed to a "revolving door"; despite the pharaoh leaving for the afterlife a second time, the power remained gone.
