Kalva

Kalva is a time-displaced Toa of Plasma who lives as a beggar in a city on the Southern Continent. Due to his Kanohi mask, he receives terrible injuries at random times due to being called forth into battle by his future self.

Early Life
Kalva was brought into being on Spherus Magna by the Great Beings in order to help construct the Great Spirit Robot. After several years of intense labor, he was placed in a village on the Southern Continent in order to help maintain the Matoran Universe.

At an unknown time, Kalva became a Toa. His Kanohi Mohtrek was also damaged in battle, which would spell untold consequences for him later.

Possible Future
Kalva's damaged Kanohi Mohtrek is linked with a terrible alternate timeline, involving near constant battle and hardship. Due to this, Kalva's present self is often called forward in order to fight alongside his future self. These battles often leave him with grievous injuries, and leave him feeling rather paranoid.

Another side effect of his damaged mask is that he can remember bits and pieces of battles. These memories often seem like visions to him, and offer him a glance of the hellish future he is often summoned to.

Personality and Traits
Kalva is a rather secluded, paranoid Toa with anxiety issues. Due to constantly being called forth into some distant future to do battle, he often has terrible, unexplained injuries, which only fuels his paranoia even more. This also leaves him unfit for combat, making him feel rather useless as a protector of Matoran.

However, Kalva can be dangerous when he does decide to fight. He is highly aware in battle, and will sometimes use his mask power in order to gain the advantage in a battle. He does not usually utilize his Kanohi, however, as he hates causing undue harm to his past self, especially considering that his future self uses the mask quite often already.

As a Toa of Plasma, he can create and manipulate superheated plasma.

Mask and Tools
Kalva wields two Plasma sickels, through which he can channel his elemental powers.

He wears a damaged Kanohi Mohtrek, Mask of Time Duplication, which allows him to call forth duplicates of himself from the past in order to aid him in battle. However, the mask's damage has linked it with a future version of himself stuck in a terrible alternate timeline, so Kalva is constantly being called into a future battle. This can cause grievous injury to himself at random. The damage to the mask also allows him to remember moments of his battle, giving him "visions" of the future.
