Idus

"'I shall manipulate the element of earth, and buckle the very rock that houses the shadows, and all who prey on the weak from it. I shall strike from them their anonymity, and once on my terms, I shall crush them with my thoughts alone.'"

Biography
Idus was a large being of unknown origin, who discovered the power to manipulate both Earth and Protodermis with his mind. He then learned of the Makuta, and that there were more than one. He vowed his power was the product of fate, and that the Toa were merely sent to protect matoran. and his destiny was to slay the dark sentient beings that overshadowed the island.

Idus then spent a lifetime hunting in the underwater and cavern realms of the island. Working alone, he cut down many winged beasts and tall giants that bludgened the ground with every footstep, often crushing the mask of his foes with his mind- crippling their power. Makuta and rahi both fell at Idus' hand.

Over a thousend years, Idus began to enjoy the decimation of creatures, and would leave a path of destruction wherever he travelled. He became darker in character and would torment the makuta species whilst decimating them.

As he sustained more and more injuries, he worked at sustaining his life energy through repairing himself with parts found from his foes, mostly coloured black or grey as darker creatures often were.

Idus, in the end

Weapons, Powers and Abilities
After learning of his great power, Idus practised various techniques of destroying his prey.

He could move and crush solid and liquid protodermis with astonishing force, furthermore he could shift and shape the earth around him. Because of this, he did not wear a mask, instead he wore a chest plate that covered his neck and face to an extent.

Idus' self made armour was of the strongest ever constructed, it locked his torso in place, he had no knee joints, effectively making him a slow, static fortress, with unmatchable strength and power. To gain speed, Idus would shift the earth under him to propell him in a chosen direction.

Idus discovered a sword whilst in Po Koro, it was an object he could not bend or break, which left him astounded. He weilded it at his side ever after, believing it to have called out to him.

His power with the sword was dimension breaking, moving the sword half with his mind, and with a single strike he would often cut a foe into pieces. sending parts flying miles in every direction. Idus did not need a weapon of any kind, but enjoyed using it all the same.

His rare power allowed him to freeze a foe in place, crush their body or mask where they stood and even halt zamor spheres and other projectiles with his will alone

Death
Idus believed himself to be invincible, but over time, his power was his downfall, in the very end Idus walked with his left leg still attached and on the right leg, a cane and had only one arm on the right side with which he controlled his sword. Idus decided to end his suffering, and went into exile. His legend proved to outlive him, as the Bohrok began to hunt down and destroy Idus, who fought off the Bohrok for a lifetime thereafter, eventually becoming tired of the life he had made for himself and of their constant assault, he became self destructive. He brought down a mountain on himself, destroying much of the Bohrok in persuit and encasing and preserving his body. This allowed the Bohrok to be beaten by the Toa Mata. The Bohrok told no such tale of the day half their numbers were drawn out and destroyed by Idus.
