Defilak

"When danger threatens from every side, faith-trust is hard to come by." -Defilak

Defilak was a Le-Matoran inventor and scholar, and it was his turn to lead the Mahri Nui Matoran when the Mask of Life appeared. He invented and built an Underwater Submarine modeled after a Takea shark in order to find out just what was preying on the Matoran, only for it to be destroyed and its crew taken captive by Pridak. After learning a bit of the Barraki, Defilak got away, and saved Mahri Nui from falling victim to a giant Venom Eel by smashing all its light stones (making it less of a target). Defilak was equipped with two Electro Blades. When the Toa Mahri arrived, Defilak initially distrusted them at first, ordering a massive attack on first Matoro and then his teammates, but eventually warmed up to them. Defilak gave them the name "Toa Mahri", telling them that if they were going to help the Mahri Nui Matoran, "We would be honored to call you Toa Mahri."

When the Toa Mahri were forced to destroy The Cord and crush Mahri Nui, they took the Mahri Nui Matoran to the caves under Voya Nui for safe travel in their return trip to the Southern Continent. Defilak is now on the Mainland.
