From Mobile Fighter G Gundam, this is one of the special martial arts moves from the School of the Undefeated of the East. It is best known for turning a fighter or mecha into a spinning ball of energy with their head visible. While it can be self-propelled, another mecha from the same school can launch it to make it even stronger.
