One Hand of Revelation is Gowasu's Super Attack in the arcade game Dragon Ball Heroes.
Gowasu condenses spheres of ki in both hands, then draws his hands back in a way similar to the Kamehameha pose. When the attack is ready, he takes out his right hand and fires the energy wave.
Whitish-blue is its standard color, but it also can be whitish-yellow. When fired, it looks a lot like the one-handed Kamehameha.
This attack was introduced in Dragon Ball Heroes, on the tenth mission of the God Mission series (GDM10).
