Don't forget about Mishima's...
Dance Dance Revolutionary Army
They commonly challenge entire enemy squads to a "Dance Off". The squad that "Gets Served" must roll their LD to challenge to a rematch, and may not do anything else until they are successful.
This is an extremely fast and agile group of weaponless warriors.
However, once they enter combat, their extreme speed only permits them to move up, down, left, or right.
The DDRA must not be confused with their lesser known, yet equally skilled, rival.
This is none other that Mishima's...
Pump It Up Squad
PIUS is made up of warriors that were rejected by the DDRA for any number of stupid petty reasons. This is what makes them "eternal rivals". They must challenge each other. Subsequently, they may never be placed in the same fighting force. Doing so would cause a "Dance Off" that would last for hours, and effectively ruin any Mishima army's strategy.
In combat, PIUS warriors may only move diagonally!
