Aura Power

Aura Power (オーラパワー) is an energy source manipulated and controlled by the Maskmen.

Gokaiger
Aura Power is the Greater Power of the Maskmen, allowing for Aura to surround GokaiOh's right hand, which does a front flip-flying karate chop known as the Gokai Aura Galaxy (ゴーカイオーラギャラクシー), which is similar to Iron Fist Aura Galaxy, Galaxy Robo's finisher, except the part to assume vehicle mode to build up speed.

The Maskman's Greater Power was taken by Basco sometime before he took the Changeman Greater Power and the failed attempt at the Ohranger Greater Power. After the Gokaigers defeated him, it was formally issued by Akira, the former Blue Mask.
