Sasuken (SMU)

In the Shattered Mirror Universe, Sasuken is Ynot's second-in-command in the Makuta Anima.

Early Life
Like his OU counterpart, SM Sasuken was once a Makuta who served in the Brotherhood of Makuta. However, in this universe, he was not chosen to chart the island of Shinobi-Nui for the Brotherhood (the reason why is unknown - it is possible that the Brotherhood never discovered the island, or it does not even exist in this universe). Thus, Sasuken was not submerged in Energized Protodermis, and did not gain elemental lightning powers as a result.

Instead, Ynot, the second-in-command of the Brotherhood, chose Sasuken and four other Makuta to be part of an elite task force known as the Makuta Anima.

Taking the SM Matoran Universe
When the Brotherhood's leader, Kakamu, left to the Original Universe through the Shattered Mirror, Ynot took charge. One of his first decisions as leader was to conquer Xia, the home of the Matoran Universe's weapons industry. The SM Anima were tasked with spearheading this invasion. In the following battle, Sasuken found himself facing off against Starscream, an Order of Mata Nui member who had arrived to repel the Brotherhood's attack. Sasuken won the battle by blasting a bolt of chain lightning through Starscream's core.

After the defeat of the Light Hunters at the hands of Ynot, Sasuken asked Ynot if everything was in order. Ynot informed him of his plans to conquer Daxia, the headquarters of the Order of Mata Nui.

At Ynot's behest, Sasuken went to Daxia and pretended to be him in front of the Order of Mata Nui's leader, Helryx. However, Helryx didn't fall for Sasuken's ruse, so they fought. Sadly, the outcome of this battle is unknown.

After Sasuken's battle with Helryx, he returned Ynot and witnessed his mind slaves in action. He pointed out how creepy they were. Ynot ignored his comment and told Sasuken that they needed to go to Destral, because it had just been retaken by Trantoshen, Kakamu's son. Sasuken accompanied Ynot to Destral, pointed out some obvious things, and offered to track down Trantoshen for him. They both then participated in the siege of Destral.

After that battle was over, Ynot ordered Sasuken to help out in the cleanup by teleporting a Tahtorak off the island.

Much later, while Ynot was happily ruling the MU, OU Ynot arrived in the SMU. Fearing an invasion from another universe, SMY panicked and ordered Sasuken to get the Mata Nui robot up and running as soon as possible so that they could repel any external threats. Unfortunately, OU Blackout played his hand first, attacking SMY's empire with Darkmount. In response, SMY ordered Sasuken, Hokagetsu, and Asumaru to steal Darkmount. However, they had no idea of just how paranoid Blackout was about people stealing his important stuff, so Sasuken was surprised when he was teleported to another universe by the ship's security systems.

Sasuken vs. Sasuken
Apparently, SM Sasuken eventually escaped the universe he was trapped in and arrived in the Original Universe. There, met his counterpart, OU Sasuken, and fought him. In their battle, OU Sasuken gained the upper hand by using his elemental lightning powers - something that SM Sasuken was missing. After learning how OU Sasuken got his powers, SM Sasuken decided to see if the OU's Energized Protodermis would react to him in the same way. To his surprise, it did, giving him elemental Lightning powers.

Tournament of the Dead
SM Sasuken was somehow sucked into the UG when its operators moved it through the Void and into the Original Universe. They, he saw SM Ynot play a part in the "tournament of the dead", which caused him to think that SMY was actually deceased. When DU Monarch returned and ended the tournament, Sasuken escaped before he could be captured and put into stasis. How he escaped is unknown, but Trantoshen, another living character who ended up in the tournament, escaped too.

Return to the OU
SM Sasuken returned to the Original Universe during the invasion through the Shattered Mirror II. He immediately left the planet he was on and set fire to a populated planet in the Crotus sector. He repeated this process several times until he got bored and decided to look for OU Sasuken instead to get revenge on him. He eventually arrived at the space station that the Ironclad was docked at, and felt OU Sasuken's presence inside the ship. SM Sasuken started throwing corpses at the Ironclad to get his attention - when OU Sasuken opened the door, SM Sasuken attacked, and the two engaged in a brawl. Their fight took them out of the Ironclad and towards the tournament that a bunch of other characters were participating in. When they crashed into the tournament, Sasuken summoned Hokagetsu, Asumaru, Kurenitsu, and Trixitin to help him force OU Sasuken to surrender.

Intrigued by their battle, Wekiga approached them and asked if he could join in. SM Sasuken responded by telling him that he didn't care about the tournament, he was just there for Sasuken, but if he wanted to fight, he'd take him on too. Wekiga accepted his offer,

Elemental Powers

 * Electricity Creation - Sasuken can create and channel electricity through his protosteel tools and hands.
 * Electrical Control - Sasuken has complete control over electricity, and can reroute current, cause it to jump from place to place, or even control electrical storms.
 * Electrical Absorption - Sasuken can absorb certain amounts of electricity into his body, which becomes stored for use in future elemental attacks.
 * Electrical Nova Blast - In extreme circumstances, Sasuken can release all of his elemental energy in the form of an electrical nova blast, which would be an explosion large enough to devastate an area the size of a large city.

Makuta Powers
Since the Makuta Anima lack shadow powers, they may also lack access to other powers traditionally held by Makuta, such as the ability to absorb other biomechanical beings and create Rahkshi. However, they are confirmed to have Kraata powers.
