Auserv

"I am Auserv, Toa of Electricity!"

- Auserv after the reversal of the Dairuno Stones' affect due to Desurk's death

Auserv is a Toa with a long, twisted history. There are two distinct periods where Auserv was actively fighting for good and adventuring with most Toa, separated by millennia spent as a Matoran unknowing of his past on Ayomeii.

Early Life
From what he currently remembers, Auserv knows that early in his life he was a Ta-Matoran, and was kidnapped and smuggled to a laboratory with many other Matoran where "they" were experimenting on them. They were attempting to change the elements of these Matoran, and with at least six of them, they succeeded.

Auserv was transformed into an Ak-Matoran (a Matoran of Lightning, though while these were normally female, Auserv remained male). He and five of his comrades (one of which had been a Ga-Matoran transformed into a female Matoran of Plantlife) escaped this island to the nearby island of Dyteeli.

League Invasion on Dyteeli
On Dyteeli, Auserv and his team found a Toa team there that was exploring the dome, using their power to make many other Matoran into Toa to protect the dome. Auserv and his friends received Toa stones, as did local Matoran Barnoka, Krandorn, and Zirralo.

Shortly afterwards, the League of Six Kingdoms invaded the dome, and Dyteeli was their first target. Auserv's team was slaughtered, and Auserv himself was the only survivor.

It then came to light that Mantax had stumbled upon a secret on Dyteeli: the Dairuno Stones, capable of changing a being into a previous form of their lives. Just as he was about to use them to reduce the remaining Toa of Dyteeli to Matoran, Auserv interfered, waging a long battle with Mantax. In the end, Mantax tricked Auserv by surrendering and then attacking him from behind when Auserv was going to take Mantax to the other Barraki as a hostage.

Auserv woke up on the Barraki's sailing ship, in Mantax's cabin. There, Mantax used the Dairuno Stones to revert Auserv back to a Ta-Matoran. Then, using a device he had invented himself, he erased Auserv's memory and kept him as a prisoner. In the end Dyteeli was forced to surrender to the League, and for this the League refrained from destroying the island.

Ayomeii
Auserv, trapped in Matoran form and without any memory of who he was or what he was doing on the Barraki's boat, eventually decided to escape, stealing a lifeboat and traveling by sea to Ayomeii, where a good portion of Dyteeli's population had been exiled to after a civil war before the League invasion.

When he arrived, the Toa of Ayomeii, named Onathei, attempted to learn Auserv's past, but eventually allowed him to move in with the other Ta-Matoran of Ayomeii, who eventually forgot that Auserv had not come to Ayomeii with them from Dyteeli.

Years later, the League invaded Ayomeii as well, after conquering the rest of Dome PV-24. In the final battle between the Barraki's armies and the Toa-Kal, the current Toa team on Ayomeii, the Matoran of Ayomeii aided in the battle. Somehow, Auserv found himself face-to-face with Mantax, who recognized him, despite Auserv not recognizing him.

Mantax and Auserv fought briefly, and it seemed that Mantax would kill Auserv when suddenly he flew away: Toa-Kal Desurk had used his telekinesis powers to lift Mantax away, saving Auserv!

But no sooner had Desurk saved Auserv than Xironu, a traitor to the Toa-Kal, arrived on the scene, hungry for blood. He stabbed Desurk, fatally wounding him. Roqini, Toa-Kal of Healing, was able to prolong his life for a few more minutes, but Auserv was so emotionally affected by this that it began to undo what Mantax and the Dairuno Stones had done to him thousands of years ago.

He became a Toa of Lightning (or as he called himself, a Toa of Electricity) once more, turning to finish his battle with Mantax that had started so long ago on Dyteeli. Taken by surprise, Mantax was defeated, and Auserv joined the other Toa-Kal and witnessed Xironu have a change of heart, saving Roqini's life just as Pridak was about to end it.

Toa-Kal of Emotion and Return to Dyteeli
The next day, Auserv found that he was beginning to regain his memories after becoming a Toa again. He also stumbled upon a prophecy, and brought both his vague memories and the equally vague prophecy to the Toa-Kal.

From the prophecy, the Toa-Kal ended up combining their power to ressurrect Desurk as a Turaga, in the process losing their Toa-Kal status and becoming normal Toa again. When they returned to the cave where they had found the fluid that transformed them, there was enough of it to transform one Toa, and the Toa unanimously decided that it should be Auserv.

Thus Auserv became a Toa-Kal of Emotion.

About a week later, Turaga Desurk had discovered yet another prophecy, this one giving hints as to how the Toa (and Desurk) could regain their Kal powers. This would involve going to Dyteeli. Auserv then discovered that the Barraki's ship had been left behind when they had been defeated and were forced to retreat.

Although Auserv originally was not going to come, due to this discovery the Toa decided to allow him to accompany them. When they arrived at Dyteeli, they discovered that it had been hit by an unknown disaster two weeks earlier, around the same time the first Toa-Kal had been born. It was hundreds of feet under water, Zirralo had been mutated beyond recognition, and the city in the center of the island was the only part that still stood.

Auserv, the Toa of Ayomeii, Barnoka, and a Ra-Matoran named Qedono journeyed into the nuclear power plant in the center of the city, prompted by a vision Barnoka had during a near-death experience. Krandorn stayed behind to keep the monstrous and malevolent Zirralo from interfering with them, and was killed in the ensuing battle.

At the power plant's basement, a strange Toa called Dairuno (the being whose energy was used by the Dairuno Stones) appeared to the heroes, asking for one of them to sacrifice themselves to restore Dyteeli to its former glory.

After a long argument, in which Auserv even nominated himself for the sacrifice, Barnoka decided that he would restore the island. As his body was transformed into energy and washed over Dyteeli, Krandorn and all of the Matoran of Dyteeli were restored to life, and the island was raised from Dyteeli.

Zirralo escaped the energy wave, remaining a monster but suffering from mild amnesia. And the heroes that had been in the basement with Barnoka were reverted to the forms they had when they had come into being--Auserv was a Ta-Matoran again.

Search for the Dairuno Stones
The now-Matoran heroes reunited with Krandorn and two more Dyteeli natives--Tyaseri and Lenurin, a Ga-Matoran and a Ce-Matoran respectively. They began a search for the Dairuno Stones, each for different purposes: while the Matoran from Dyteeli wanted to restore Zirralo to her former state, the Matoran from Ayomeii (and Auserv) wanted to become Toa-Kal again.

First they traveled to the Water Temple of Dyteeli where Zirralo attacked and defeated the Matoran. Through some new power of hers, she "brainwashed" all of the Matoran present and led them in an attack on the capital city of Dyteeli. Tyaseri escaped this brainwashing and instead only pretended to have been affected, slipping off unnoticed and getting Krandorn to help. They gathered a small army of Matoran, defeated Zirralo, and healed their Matoran friends.

It then came to light that Barnoka still existed in energy form--just as Dairuno was able to speak to beings while they dreamed or, in the presence of a Dairuno Stone, so was Barnoka. While the Matoran slept and talked to Barnoka in their dreams, Zirralo escaped, trying to form a different plan.

The Matoran now split into two teams. Auserv, Grunekt, Guutana, Roqini and Qedono went into Dyteeli's jungle to search for the Dairuno Stones in the Rahi Temple, while the others went to the underground Earth Temple.

Auserv's team ran into a giant beetle, which Qedono defeated by renting a gigantic bird from the Rahi Temple. The two Dairuno Stones there--the Dairuno Stones of Teleportation and Enlargement--were found and the team moved on to the ruins of the Plantlife Temple, unaware that Zirralo was waiting for them, carrying the Dairuno Stones of Strength and Temperature.

When they arrived, Zirralo ambushed them. Auserv used the Dairuno Stone of Enlargement to become gigantic and fight Zirralo. She stood a good chance using the Dairuno Stone of Strength, but Auserv was able to defeat her. Returning to normal size, he shrunk Zirralo and Roqini carried her along in her pack.

The rest of Auserv's story has yet to unfold.

Powers and Tools
Auserv carried a Thunder Staff as a Toa (and used this same weapon to channel his concept of Emotion as a Toa-Kal), and wore a Mask of Lightning in the shape of a Great Huna. As a Toa of Lightning, Auserv could summon lightning storms and channel enough electricity through his staff to fry the average being like a bug touching a bug zapper. As a Toa-Kal of Emotion, Auserv could make friends enemies (and vice versa), make a being happy, sad, mad, or whatever else he wanted by expending a small amount of energy.

Personality
Auserv is calm and friendly, generally, but can be quick to anger and has a vicious temper in battle. He isn't a violent person, and thus doesn't prefer to fight, but has such a deep hatred for the Barraki (especially his rival Mantax) that he becomes infuriated just to think aout them.

Trivia

 * Auserv calls himself a Toa of Electricity because his friends teased him for being a male Toa of Lightning. Thus he decided that he was not a Toa of Lightning but instead of Toa of Electricity, which had to be slightly different from lightning. Similarly, the female Toa of Plantlife on his team called herself a Toa of the Green as opposed to a Toa of Plantlife.
