Keelo

Keelo was an Onu-Matoran who was mutated into a very powerful Toa of Earth, Fire and Lightning after putting on the Mask of Catastrophes for the second time.

Early History
Shortly after the creation of Helryx, the Great Beings created The Dozen Venturers, with the purpose of exploring the Matoran Universe to check for "glitches" in the world. Keelo was one of them. After the Great Beings decided that the Venturers were not needed, he and the other eleven were transfigured into Matoran and relocated. He was transformed into an Onu-Matoran. Any recollection of being one of the Dozen Venturers was wiped from his mind.

Keelo joined the other Matoran in exploring the Matoran Universe, not knowing of his recent history. Eventually, these Matoran were split up, and Keelo travelled with three other Matoran to Leskya Nui, where they fit into the local population. At some point, attacks led by the BoM hit the island, and Vandir, Hatar, an unnamed Su-Matoran, and four other Matoran were turned into Toa to defend the island. After they failed to do this, Vandir, Hatar, and around twenty Matoran (including the other two Venturers) were the only survivors, and fled to the seas.

The Feral Plains
Keelo lived at a colonist camp, and was one of the designated night guards. He was also known for thievery, stealing more food than the rations the refuged Matoran were given.

On one round of stealing fruits, Keelo hid in a patch of vines from Jeko and Turi. There, as he began eating the stolen crops, he came across a peculiar mask with strange markings. When he put on the mask, he received a vision of himself as a Toa in the future, and a mild earthquake began. Turaga Maroona saw this and realized that something was wrong.

Later, during an attack at Lake Faradi by the native Toa, Keelo fought against the Toa of Powai Nui with a blaster. He then hid in the trees above the lake, watching as a frshly-resurrected Makuta Hysterix began wreaking havoc on the battle field. Having brought the mask he found with him, he decided to try and use it's power to "win forever". After placing the mask on, an earthquake struck the battlefield, causing him to fall into the lake. At the same time, Maroona was electrifying the lake water, with the purpose of shocking Hatar. When Keelo entered the water, a combination of the mask's incredible power and the lightning created an effect similar to what created the Toa Inika. This mutated him into a Toa with the added elements of Fire and Lightning, which the mask could control to some degree as a part of it's power. After Keelo leaped out of the water and showed off his power, the natives lost the battle.

Over the course of a month, Keelo formed an empire from his colony, crowning himself the "Emperor" and conquering much of Powai Nui. At some point, he tortured Detras for resisting his leadership, until the Toa of Fire escaped. He also beat and shut down the mechanical Dark Hunter "Alchemist", leaving him outside in the bushes, for unknown reasons.

Later, Lewok was captured while on a reconnaissance mission, and was hung from a tree limb and brought before Keelo. The emperor told the Toa of Air about himself, and then told him that he was going to use his mask power to aid his conquering of Powai Nui.

Keelo decided to send Vandir and the new Toa Merdana in search of the remaining natives, especially Detras, and Shensii, a Ga-Matoran who betrayed him and escaped with the Toa of Fire. Vandir and Merdana returned beaten and bruised, but did know of the Aqueduct Base.

Makuta Hysterix stuck around, hidden from the public, as Keelo told the Matoran of his empire that the insane being had been killed during the battle. Hysterix gave Keelo ideas for ruling, but also displayed physical dominance over the Toa. In fear, Keelo refused to claim his true leadership over the Makuta, and began regarding him as a superior rather than an equal.

Note: Keelo's story is still being written.

Powers and Equipment
As a Toa of Earth, Fire and Lightning, Keelo can control the three elements individually, as well as combine them in the way other Toa can (for example using Earth and Fire to create brick). He wears the Legendary Mask of Catastrophes, a destructive and powerful mask which can create, dissolve, control or guide many natural disasters such as tsunamis, earthquakes, cyclones, floods, and storms.

Keelo wields the double-bladed Cataclysmic staff, which he uses to direect his powers. Much like his armor, one side is blue, and the other red, representing Lightning and Fire respectively. He is able to split it in half to aid him in combat. He rarely carries this weapon outside of combat.

Personality
As a Matoran, Keelo was rebellious and uncaring, and was hungry for power, both physical and political. As a Toa, he is more than eager to excercise his immense power, frequently resorting to beating those who resist him. He finds pleasure in having others work for him, and would rather send others to do his bidding than do anything himself, unless it would please him.

While Keelo is very prideful of himself, inside he is truly a coward. He fears Hysterix, even though he is likely capable of beating the rogue Makuta in a fight. He also completely disregards the Toa Code, and forces all who obey him to do the same.

Trivia

 * Keelo's personality is based off of many depictions of corrupted rulers in history, literature and film.
 * Some may notice his name is very close to "Kilo", the Greek root meaning thousand. This could be a creative way of describing the extend of his power.
 * While Keelo prefers to be called "Emperor", and the group he rules over is called his Empire, it is not a true government. He truly only uses these terms to make himself sound intimidating.
