Brotherhood of Darkness

Abilities & Traits
Toxon was very devoted to his work, even to the point of threatening Teridax himself should he inturupt. He was intellegent, cunning, and very skilled in combat (though he usually left fighting to the Brotherhood's Rahkshi and Visorak).

Toxon's powers included elemental shadow powers, shape-shifting abilities, Kraata production, and many other powers.

Mask & Tools
Toxon wore the Kanohi Taiku, Great Mask of Poison. His tools were two pairs of razor-sharp arm blades that could be used to slash opponents as well as focus his powers. He also had sharp claws.

Army
While Toxon's army was smaller than the other Dark Brotherhood leaders, it was fierce none the less. It was made up of Rahkshi, ex-Dark Hunters, Rahi controled by Infected Kanohi, Visorak, and Exo-Toa.

Once Toxon was killed, however, the Brotherhood of Makuta was able to bring the Rahkshi, Visorak, Rahi, and Exo-Toa back to their side, using them to kill most of the former Dark Hunters that they were once allied with.
