Ackmare is the oldest of the Makuta Brothers, by a lot. He is the one responsible for the killing of the Toa Nuva (In my world, they are called the "Great Toa", because everything happening in my world of Bionicle is happening approximately 1,000 years after Teridax (Makuta) was defeated). He is armed with a flamethrower and a Fire Lance, and has the ability to create fireballs and infernos, which is what he's well known for.
