Exeller

"Ready for Round One?"

Exeller is the titular main antagonist of Sonic.exe: The Spirits of Hell series created by Danuha2526.

Past
Exeller was a third class Highest. He had good grades and a perfect altitude. He wanted to be an Earth Protector to be able to travel around Mobius without the king stopping him. He didn't think Mobians were as bad as his teachers said they were, as his friend, Alice (who Exeller did not know that she was his sister), interacted with a few, and she said they were nice. Later, Exeller had a meeting with other third class Highests. There, he and the other Highests found out that the 'person with the red eyes' was not a person at all, but they didn't know what it was. The king later found out about this trip, and was not happy. He punished them. He didn't know what happened to Alice. Rexer got off with a warning, while Laura, Phil, Wayne, and Exeller himself had their magic prohibited for an entire week. Rexer promised them that he would show the last memories of his victims. Exeller found this to be creepy. Alice and Exeller would go see tomorrow, but Laura and Phil did not want to come. One day, Exeller and Alice traveled to Earth. They did not find a trace of the fore mentioned 'person with red eyes'. Along the way, they met two Mobian hedgehogs- one was a child and the other one was older. Alice found the child to be annoying, but Exeller found him to be kind of cute. They came back to the Eternal World, and decided to relax. They gathered the other third class Highests into the Terra Woods and tried some things that they learned from Mobians. There, Laura kissed Exeller, breaking the rule that third classes cannot have romantic relationships. Later, Exeller found Laura infected in a cave. He only saw madness in her eyes, like the the eyes of the Highest in the victims' memories. She died, disappearing into ashes. Exeller was greatly affected by her death. Alice and Rexer had found some strange energy on Kuri Mountain, and Exeller contemplated joining them. Eventually, Exeller was cursed somehow, unlocking his abilities that were once dormant. One day, he kidnapped Wayne and cut his limbs off, gouged out his eyes, cut off his ears, and blocked his mind so no one could read his memories. Exeller felt satisfied by how he had defeated a second class, but he later felt regret for doing it. He realized that he didn't need to kill to be satisfied, as people's mere suffering satisfied him entirely. He went to find Alice so she could answer some of his questions. Later, he came to Mobius and he tried to terminate everyone.

Sonic.exe: Spirits of Hell: Round One
Exeller is the main antagonist and therefore plays a major role. Sonic was walking in Green Hill, and talked to Tails before being possessed by Exeller. Exeller took over Sonic's body. Exeller found out that he didn't have enough souls, so he started tracking down Tails, Knuckles, and Eggman. He tends to break the 4th wall as shown as he alongside Tails.exe appeared before the end credits and killed Knuckles and Eggman during their duo ending. He also reveals that solo and duo endings didn't count as good endings as he kills the survivors offscreen before telling the player to try their luck at getting the best ending. In the Best Ending, Tails, Knuckles, and Eggman survive their encounters with Exeller because he lets them. They all arrive at Hidden Palace one by one and form a plan to go to Sky Sanctuary because they're confident Exeller can't sense them there. They teleport to Sky Sanctuary using the Master Emerald, but Exeller is already there. In a final attempt to kill the three, he creates clones of himself to fight each of them. They eventually escape through a giant ring to Mountain Peak, with Sonic temporarily taking back control to tell Tails to run.

To Be Added...

Personality
Exeller is sadistic and cruel. He punishes his servants if they fail to follow his orders, however nowhere near as badly as Sark does. However, despite who he is, he claims that he's not like the other exes. He even restarted the timeline to give his victims another chance to survive.

Appearance
When in Sonic's body, Exeller looks identical to him except his eyes have black sclerae with red pupils and blood coming out of them.

Abilities
Exeller can use any type of magic, but he prefers to use time, soul, and illusion magic. He can create weaker clones of himself, as well as fly, teleport, and disguise himself as Sonic. As Exeller is not a demon, he does not demonize his victims. Instead, he uses dark soul magic to turn them into his slaves and take the form of their dark side and fears.
