Mask of Strategy

The Mask of Strategy was born when Tapio was separated from the Ketawnki and turned into a Toa. He could use it to create great, strategic plans. The mask also made him slightly smarter than normally. The mask was lost when Tapio sacrificed his power to destroy Tonga and energy flew through him, making him into a Mega Matoran. The mask transformed into the Mask of Laser.
