Avaccodo

Every single time the universe enters the Planck Epoch, energy is created, since energy normally can't be created negative energy must also be created. This negative energy takes the form as Avaccodo.

The first few Avaccodo's
The first Avaccodo was created at the beginning of the first universe. There are infinite amounts of universes at the start, and she didn't know how to sustain her self so she would just disintegrate one second after creation. After a few universes, she managed to stay together and began her mastery of her own atomic structure, which gave her the ability to Quantum tunnel through objects and disassemble her self then reassemble in another place. This ability made Avaccodo one of the most powerful entities in the universe. The only problem was she couldn't interact with normal matter because she was antimatter, and if she were to react with normal matter, she would be annihilated instantly.

Motives (Not your Swords)
Swords in his first universe was not as polite and understanding, or he just wasn't the purest being to exist. Being 16 at the time, he was like any other human during their teenage years. Swords was very polite but had other motives for continuing science. What Swords wanted more than ever was to be the most powerful being in the universe.

Found
Swords detected an anomaly. He detected a large quantity of Anti-Protons and Positrons 16 light-years away. By normal means, this would be unachievable, but Swords got there because he is Swords. Swords didn't know what power he possessed in his first universe. He was just a normal human born in 2005 but was infinitely times smarter than his peers. Therefore he was able to track the individual positrons of Avaccodo's structure (I swear this makes sense :) ).

Retrieved
He had wondered how such a mass of antiparticles could exist in such a big clump. So in the Swords fashion, he developed technology that could bend space-time to travel through the universe without gaining speed. He retrieved a sleeping Avaccodo from the depths of space and brought her to his super secret base in the mountains that he first made in Minecraft and then made in real life.

Beginning of pain
Avaccodo sleeps for two universes at a time since they never sleep during one universe. This was her second universe asleep Swords managed to figure this out somehow and with this knowledge started testing to see why she was able to reset with the universe. Swords wasn't able to recreate the ability to control his atomic structure but was able to make himself be born into each reality with all his memories with thanks to Avaccodo. But Swords wanted even more power. He wanted to control his own atomic structure. So he continued his testing, and after many years of testing on this 'god', Swords was able to gain basic control of his atomic structure. He could make himself vibrate or gain kinetic energy, which at high enough levels could create time dilation, but Swords couldn't do it on Earth as it would destroy everything there.

New found power
Swords had the power of a demi-god, but the new abilities made him crave even more power. He started working to improve his ability's even further, and at the centre of this was Avaccodo. She had to go through insanely painful procedures. Swords thought that she couldn't feel any of it, but even though she was sleeping, she could feel every slight touch without being able to do anything about it. The tests persisted for 26 years, then one day Swords did his most horrific test. It caused so much pain in Avaccodo that she lost control of her Atomic Structure and started falling apart. Swords thought she was teleporting, but she was rewiring her version of a brain to not feel any pain.

Completion
After many years of test after test, Swords had completed his powerset, although not to the level of Avaccodo. After many years, her pain suddenly stopped, and peace was restored to the mind of Avaccodo. She was able to rest in peace. Unfortunately, in the process of the reassembly, she had forced herself to forget everything that had happened during that universe. Swords also saw no reason to stay in this dying universe and wanted to see what it would be like to transfer to another universe. So he travelled through time to the end of the current universe. Then it went black.

First view
Avaccodo had woken up again into heat, the fiery blaze that was the beginning of the universe, and just like every other time expansion, the freezing of this universe began to occur. Nothing was new for Avaccodo, but she felt something she experienced something that she never had before visions. She could see what Swords had done to her, and she felt so much pain, but no real pain just in her head. She wanted to forget this was also something new for her. She also felt emotional fear. The others would come soon like a thunderbolt. But for now, she drifted through the endless expanse of the universe. She drifted for billions of years but the sense of pain and fear never left. It was lingering. She just felt terrible all the time, and nothing she did would be able to resolve this, but... she went on maybe it was because she couldn't die, but she found ways of passing the time of years. As it turns out, years in a void go by quick before she knew it, earth and its inhabitancies had already existed for years.

New Swords
Avaccodo was drawn to a person, the person who managed to make it to the next universe. This person was Swords. She was drawn to Swords because of the similarities in their structure. She asked who in the world Swords was, which caused Swords to be in disbelief. He didn't think that this god person would have arrived at his little house on the hillside. Then someone comes running it was Swords child, his daughter who was five years old. Swords forced her to leave because he thought that she was here for vengeance. But Avaccodo did not know what to think at the current moment she had so many emotions new to her rushing through her head. Happiness, Sadness, Hatred, Fear, but didn't know where these were coming from and since she was drawn here. She asked why she felt such a strong pain when she saw Swords, and Swords went white. Swords began to tell her how he got his power and expected to be blasted all the way to Ecuador and back within the span of 1/3 of a femtosecond. But nothing like that had happened Avaccodo was filled with rage but didn't want to act on that rage, she didn't know why she usually did anything she wanted to, but this time she mentally can't imagine doing something like that.

Swords new ability
While Swords was away, he created his daughter out of thin air and was filled with so much love and emotion he had not felt in so long. He gave up his ways of getting new power and wanted to make amends but couldn't find the mysterious god anywhere, so he gave up his search to settle down with his daughter. Then Avaccodo arrived and they went through the talk, but now Swords was at a state of such pureness that Avaccodo's mind couldn't imagine hurting such a person and she was getting charmed by his just brilliance and pureness after that first meeting she would only leave Swords side four times within a period of 3 years.

Misfire
Then while she was faking to sleep, she actually fell asleep this was the first time she went to sleep on her own accord. Unfortunately, this would only prove to be disastrous while asleep she lost control over her abilities and disassembled Swords daughter. When Swords woke up to see what had happened, he reopened his dormant ability's once more to put his daughter back together. Unfortunately, he could only get a few strands of her cells to work. He kept those strands for eons. While this was happening, Avaccodo had fled Swords world. Swords was filled with so much grief after losing two prominent people in his life that he didn't try to interact with another person for eons, as he feared he would lose them.

Ecuador
Avaccodo had left Swords because she didn't want to face what she had done. She ruined the one person she cared about. She felt an even stronger version of the sadness she felt before. The sadness never left her. It became the opposite. It grew stronger the more she tried to suppress the emotions and memories that relate to Swords. She couldn't get rid of them completely but she managed to banish most of them to Ecuador which is where the dead lie. Ecuador is located on Earth, but no mortal can enter Ecuador without an extreme amount of power which in most cases is caused by death. All the energy released when death occurs sends them to Ecuador. This place is where Avaccodo sent most of the memories of Swords. But she would constantly have flashbacks and would feel a lot of distress when thinking of the incident. She left the milky way and would try to avoid it as much as possible.

Hatred
Avaccodo stopped sleeping because her mind related that to the incident. Her mind was changed by Swords, she now required to sleep on a somewhat human basis, the reasons why are unkown and counterintuitive. She felt so angry all the time she didn't know why, then out of pure rage destroyed an entire supercluster. She may have thought that destroying such an object would ease her mind, but she felt no different, the sadness persisted, and she couldn't do anything about it. In the wide expanse of space, nothing exists, nothing but Avaccodo, no one to talk to. She had missed those moments. She felt so empty with nothing to do, just in a world with her thoughts. She tried to remember the times, but couldn't she locked most of the memories in Ecuador. She would never be able to complete her memories of Swords.
