Flame Sword

The Flame Sword was the Glatorian Ackar's primary combat weapon.

Shortly after arriving on Bara Magna, Mata Nui used the power of the Kanohi Ignika to give Ackar elemental fire powers. He could channel them through the Flame Sword.

Example Usage
Ackar used it to defeat a Skrall in the Battle of Roxtus.

Trivia

 * In BIONICLE: The Legend Reborn, the Flame Sword changed shape when Mata Nui gave Ackar elemental powers. However, this is considered non-canon.
