Mask of Catastrophes

The Mask of Catastrophes (sometimes called the Petreda or Petorra) had control over natural disasters. It was near the level of a Legandary-power-level mask, but not powerful enough to be considered one.

History
When a Great Being was using the Mask Maker's Tool, it was accidentally dropped into a pile of unpowered masks. It released a large amount of mask power into one mishapen mask, creating the Mask of Catastrophes. It was considered "revolting" by many and was discarded.

At some point in time the mask found it's way onto Powai Nui, and after some time Keelo found it while escaping from a heist. When he placed it on, the mask gave him a vision of a Toa-like figure in a destroyed landscape, and ferocious winds and a mild earthquake broke out.

Keelo kept the mask, and during an attack on his colony by the "native" Toa, he placed the mask on again in an attempt to "win forever". This eventually resulted in him being mutated into a Toa of Earth, Fire and Lightning. He was then able to stabilize and control the mask's power to some degree.

Abilities
The Mask of Catastrophes can create, disperse, contain, guide, or control the magnitude of a plethora of natural disasters, such as: Other disasters, such the spread of disease, famines, or swarms of insects and Rahi, apparently do not fall under any of these categories and therefore cannot be controlled by the mask.

Trivia

 * Because of the randomized conditions under which it was created, it would be next to impossible to create another mask with the exact abilities of the Mask of Catastrophes.
 * Because few Toa ever heard of it, it could not be determined if they considered it immoral. However, it was considered "taboo".
 * Because of the manner of it's creation, the Mask of Catastrophes does not count as a real Kanohi mask. It's rarely used titles of Petreda and Petorra are the shortened Archaic Matoran phrases for "natural disaster" and "impending doom" respectively, coined by Maroona when attempting to describe it.
