Her world is a super-hero-type in the local cosmology. Basically just insert a random mix of any Marvel/DC or whatever tropes. It's got all you could want from such a setting. However, the main problem here is that for her world? Supers are a new thing. By whatever means they gain their abilities, they have appeared only within the latest 3 decades, and the local Avengers/Justice League has yet to form until the end of her Journey. Thus, on a cosmic scale, this makes them... vulnerable.

Jen is a black-souled human from this world, who was born with a connection to the White/Red concept of SPEED. If there's an absurd speedster feat in comics, you can bet there's a good chance she can pull it off using said magics. She was eventually forced to begin bettering herself and mastering that power very young when her world became a target for conquest by what was effectively a wuxia protagonist with a god-complex (which is basically all of them). Given that her world didn't have an established team to defend it, it quickly devolved from the golden age of supers into a mix of a deconstruction of a superhero world and the post-apocalypse.

Over time, as her mastery grew, Jen would end up essentially becoming the most famous "speedster" of her world, a dedicated hero who was often the only thing between the world and total conquest, despite her relative youth. Her sheer speed was simply something that the wuxia invader couldn't overcome without extreme effort. If she so much as heard of a battle, she could be there in minutes at the absolute most. Bases could be evacuated, injured rushed to medics and healers. If she was on the field, it was nigh impossible to make any lasting deaths happen among her fellow heroes and the world resistance.

The Invader soon realized he couldn't overcome her speed in a straight fight even with all his supernatural martial prowess; unfortunately, this forced him to fight smarter, to be subtle so that her interference was a nonissue. With bullshit determination and what could only be described as "basically plot armor" by those that fought him, The Invader sought godhood and made steady progress towards that goal, forcing the world's defenders to slowly but steadily give ground. After all, Jen couldn't be everywhere at once.

Eventually, the final battle culminated in the Invader achieving his goal, nearly cultivating his soul to a higher plane of existence. The ritual to achieve godhood was repurposed into a brutal sacrificial rite that would both herald his ascension and simultaneously kill the heroes that came to stop it, using them as the sacrifices. The ritual was an abhorrent success, wiping out a large portion of the planet's population, even as Jen herself vibrated her atoms and very soul enough to phase through the wave of annihilation.

By this point, Jen had achieved the peak of what could be had without taking a very dangerous step: time travel.

She was wary, and every possible bit of research, training and instinct within her screamed that attempting time travel was a fool's errand, more likely to cause a paradox than anything even remotely similar to what she'd read in comic books. That said, it was the only thing she had left, and she had a theory about how she could make it work.

Speed of light remains constant irrespective of the observer
It is observed that as the speed of object increases, time slows down
At the speed of light, time stops
And on further increment of speed greater than light, time reverses
Thus to travel back in time we have to move faster than Light

These were the steps, almost too simple to be believed. But in order to prevent the paradox caused by her own existence from occurring, Jen added one further: She would sacrifice her past in order to ensure that her physical appearance in the past as an adult would not cause a paradox or otherwise unintentionally screw over the universe. She'd never attempted time travel before, so she felt that this was a necessary step to cover for her inexperience. Perhaps if she had even further mastery, she could have pulled off flawless time travel, but for now, this would have to do.

As she ran, she went for broke, unwilling to let her sacrifice be in vain, knowing that everyone she knew and loved would forget her very existence -that she would have never existed to begin with. Thus, she didn't just erase the battle, the defeat. She reversed time by years all the way back to the exact moment the Wuxia Invader had arrived in her world. And as she did so, the disappearance of her very past caused her body to begin to come apart at the seams. Into order to retain cohesion and survive, she began to infuse herself with the very concept of speed, joining herself with a fundament of the universe, a part of her mortality inextricably cast away to achieve a status above human, that which would let her prevail. As she traced the Invader's path through time all the way back to the start, she readied herself for a battle that she would have never been able to give him decades ago.

She found the moment of the Invader's entry, reentered the proper time-stream, and then attacked him with every bit of her fully cultivated power against his far less experienced self. Despite being objectively far older than her when he arrived, his future self had learned how to fight a weaker her as they both grew and adapted to each-other in turn. To bring her strongest self to bear against him at his weakest after he had expended great power to cross the boundaries of worlds? In that moment, he was vulnerable, and she struck with blows faster than the flow of time itself, a merciless barrage of vibrating attacks that completely stripped him to nothing, reduced to mere atoms that would never be able to reconstitute, no matter his training.

However, there was a cost for this victory. The Invader had still been resolving the effects of his dimensional technique when she struck. The combination of such a technique imploding and Jen's own state of still-resolving ascension and loose grasp on the reality at hand caused her to be nicked by the collapsing technique and thrust from her world.

As she arrived in a place unknown, she found that her very being had been fundamentally changed by the experience and her sacrifice. In order to maintain her existence, she had not merely joined herself to the concept of speed. No, for to join herself with her own universe's rules of reality would have resulted in her unraveling the moment she left. Instead, she had managed to transform herself into a sort of moving "universe of Speed" in the shape of a human. Her very self was a self-sustaining battery of an existence that molded and adapted itself to instead by fueled merely by Jen's own belief and perception of Speed.

She had lost her world and saved it in the same breath. She knew that no-one would ever remember her, that no sign of her existence would or could ever exist. There was nothing left for her there. Perhaps, one day, she might find a way back, but for the time being? There was a new world to save and new evils to face. She had become something new, some more, and now that she had taken the final step of her prior journey, it was time to take the first step of the new.

Name: WIP

Titles: Celestial Trinity

Age: It's complicated. Somewhere between 25 and 200.

World:
In a world where magic and technology were indistinguishable, and Celestial Avatars ruled over them, colonizing an entire solar-system was of no issue. Expanding the solar system became a plausible concept. It was a world inhabited by citizens of the stars. Was.

Race: Human-ish
Form: Watch me WIP, now wa-

Legend:
A people capable of not just terraforming an entire solar system, but adding onto it, would seem unstoppable. However, doing so was tantamount to chumming the water. It was as if space itself took form and began to close in on them. A great, glittering ink-blot that wanted to swallow all of creation.

The Celestial Avatars could only slow it. The power of their sun was all that kept it at bay, but its power could only be stretched so far, and without the planets and moons that orbited it, the spark of magic within the celestial body would be weakened, leaving even it vulnerable.

So the Avatars surrendered themselves. They gave up their power, hoping by transplanting it into their people that it could grow beyond their current potential. It was all concentrated into three siblings; a boy and his two sisters. Earth, Sun, and Moon. At first they seemed like any other, fighting against the beings spawned by the encroaching void. However, their powers grew and grew, until they were far beyond their peers.

It wasn't nearly enough.

There was one last trial they needed to conquer in order to reach their full potential. They needed to transcend beyond what they were and reach a level beyond the original Avatars themselves. They needed to go to the heart of the first moon; a place that embodied all that was celestial. A place that mirrored sunlight in the darkness and was solid ground, but was neither the sun or earth.

Deep within it, within its raw essence, time did not flow the same. It was an agonizing, lengthy journey, and each time their earth eclipsed the sun, the moon was left vulnerable, letting their enemies pursue them. The combined stresses of the Lunar Core and their enemies was too much. The brother, his powers always the weakest and most mundane, could not keep up. Under the harsh conditions, his sisters had to protect him despite already being pushed past their own limits.

It was at this lowest point that the answer was stumbled across. As sisters were on the brink of falling, he strained his abilities to the max in a seemingly futile attempt to sustain them for a few moments longer before he shared their fate. Instead, their powers were drawn into them, turning three into one. His powers, while themselves the weakest, could channel those of his sisters. It was a state of being beyond anything the Celestials had ever imagined.

Their enemies were vanquished. Their seemingly endless journey brought to a swift conclusion.

Finally, the void itself pushed back and all but vanquished.

Will: Complete disillusionment of the beings that were supposed to protect them.

Mastery: The brother is a sort of living nexus, with a mastery over the essence of earth, manifesting most powerfully in the form of crystalline constructs. He can set loose one of his sister to join him on the field of battle, enhancing their shared power from the backline. Or, while they remain fused, he can unleash their full celestial might, albeit at great costs to his physical wellbeing.

The first sister, with Lunar based abilities, can create mirrors and portals, as well as magic that controls water.

The second sister, with Solar abilities, has powers of heat and light, but perhaps surprisingly not fire itself. Instead of fire, she has a powerful control over gravitational forces. She also has strong regenerative abilities. The strongest of the trio.

That doesn't mean fire is off the table, however. With their powers now fused, their trump card is the "Sol Gate" which unleashes an apocalyptic stream of solar flames.

Ascent:
"It is time. The battle is won. You may return what was gifted." The shriveled shells of the Avatars stood before him.

"What will happen to them?"

"Without our powers within you... you already know." They bowed their heads solemnly. "It was a long battle. You may rest now. Return the responsibility to us."

. . .

"Why?"

It was as if time ground to a halt. Was this... defiance?

"These powers were not meant for you or your kind to begin with, and have now grown further. Return them to us, and-"

"No. You could have stopped this. You put this on our shoulders because the price for you would have been too high. You could have combined these powers yourselves, but you would have lost yourselves. You put your identities over all else." The air around hem grew unbearably hot as what seemed like a small sun began to form. "So I'll ask again: Why?"

"But it worked!"

"Yes. It did. So we'll wield this power now. You can rest." The small star burned ever brighter, its sinister heat intensifying.

"You can't possibly seek to destroy us with our own power!" The husks recoiled.

"I would hope not. That would just be pathetic." He looked down upon them with a derisive stare. "But... then again..."

And pathetic they indeed proved to be, but to slay a higher being, even ones so reduced, is considered a profane, heretical act from which reality itself may recoil...

Ephemera: The Lunar Core resides within his body, pushing their magical capabilities to new heights.

Theme: Pick a theme song, a battle song, a motif, all of the above, whatever. Try and be creative. You know you want to.

Name: Jen Shiragami

Titles: Flashpoint, Vanquisher of the Unspoken, The Hero Who Never Was, Fastest Woman Alive

Age: 21 physically... and a fair bit older mentally if one considers her living extended periods with an accelerated mind.

World: Earth Q is an Earth variant world once reduced to a post-apocalyptic wasteland by decades-long war with a Wuxia-style Invader, were it not for Jen's final heroic act during her ascension restoring it to a golden age of relative peace. Magic and supernatural abilities are a fairly new phenomenon on this world, barely 30 years old, and are thus poorly understood and with shaky foundations for training.

Race: A black-souled/Perceiver human(?), Jen developed from her youth a natural and intuitive connection to the forces of Speed. By all accounts she is otherwise a bog-standard human woman of Japanese descent... at least on the surface.

Form: Jen appears as a young human woman of what could be described as be Japanese heritage. As a result of her ascension, this appearance is more a thin veneer than anything. Having been forced to cast aside her mortal form in truth, the illusion falters when she uses her powers to any real degree, revealing a semi-ethereal blue humanoid being that appears to be more a living, moving galaxy than anything else.


Legend: Jen's world was woefully unprepared for an invader with the bullshit of a Wuxia protagonist behind them. A war of decimation with the goal of godhood was waged against her world, and Jen from the age of 11 found herself participating. The war went on for a full decade from her joining, and Jen's power over Speed was cultivated and mastered in that time, her personally confronting the Invader many a time and often being the only thing between her world and annihilation. She in many ways became the face of the resistance, and her very presence tended to at least guarantee that the enemy could not win outright.

Widely hailed as humanity's savior, she was a one-woman army, known to slay and save thousands in the blink of an eye, entire armies liberated or laid to waste at her leisure. Rumor said that should one have a way by which she may hear them and so much as call her name, she could cross the ocean to aid the besieged before the words ceased to flow. Her final battle with the Invader would see her finally initiating a last desperate stage of her personal cultivation, resulting in her victory, along with her ascension and removal from the entirety of her world's memory and history.

Will: Jen dedicated herself to heroism and war from a young age. Time and again she has fought for the sole purpose of saving lives and opposing an unparalleled tyrant of a madman. Despite having finally defeated said tyrant once and for all, she cannot lay such instincts completely to rest. That said, facing a new world with new people and evils, Jen can only feel a looming sense of... exhaustion. Having sacrificed everything for her world and spent half her life at war, Jen now desires to try living for herself for a change, to seek personal peace instead of peace for the sake of others. To that end, she intends to explore the new limits of her existence/body and shatter them all over again, to cast down any threat to her peace, and to finally have what she always reserved for others... hopefully without compromising her moral compass... much. It's time for the selfless hero to be a bit selfish for once.

Mastery: Jen has long cultivated a natural intuition for manipulating the primal forces of Speed, to a degree that steps even into the realm of space-time. Her mastery has seen her surpass even the speed of light and the flow of time itself, and her ascension has seen the obtainment of near-immortality through the stark transformation of her body to one more akin to an elemental of Speed than anything else.
Broadly speaking, if one can so much as conceptualize a usage of speed, it's fair to assume she can make it happen -or figure it out if not; she is basically a living embodiment of Speed.

Ascent: During the Wuxia Invader's ascension ritual, a genocidal sacrifice was initiated, wiping out a large portion of the planet's population and ensuring the Invader's ultimate victory. Instead of allowing such an atrocity to pass, Jen was forced to use time travel. She was wary of causing a paradox, but it was the only thing she had left, and she had a theory about how she could make it work.

Speed of light remains constant irrespective of the observer. It is observed that as the speed of an object increases, time slows down. At the speed of light, time stops. And on further increment of speed greater than light, time reverses. Thus, to travel back in time we have to move faster than Light. And Jen's personal step: sacrifice her own timeline to ensure that her appearance in the past would not cause a paradox.

She didn't just erase the battle, the defeat. She reversed time all the way back to the exact moment the Wuxia Invader had arrived in her world years ago. As she did so, the disappearance of her very past caused her body to begin to come apart at the seams. In order to retain cohesion, she infused herself with the very concept of speed that flowed more freely around her now than ever before, crafting a new body from the fundament of the universe, a part of her mortality inextricably cast away to achieve a stable existence outside her own timeline.

She found the moment of the Invader's entry and attacked him with every bit of her fully cultivated power against his less experienced past self, a merciless barrage of high-speed vibrating attacks that reduced him forever to mere atoms. However, the Invader had still been resolving the effects of his dimensional technique when she struck. The combination of such a technique imploding and Jen's own state of still-resolving ascension and weakened grasp on her world's timeline caused her to be nicked by the collapsing technique and thrust from her world entirely, as her ascension solidified and completed in truth.

Arriving in a place unknown, she found that her very being had been fundamentally changed by the experience. In order to maintain her existence, she had not merely joined herself to the concept of Speed. No, for to join herself with her own universe's rules of reality would have resulted in her unraveling the moment she left. Instead, she had managed to transform herself into a sort of moving "universe of Speed" in the shape of a human. Her very being was a self-sustaining battery of an existence that molded and adapted itself to instead be fueled merely by Jen's own belief and perception of Speed.

Ephemera: The Speed Nexus is a self-sustaining existence within Jen's body of her own semi-unintentional creation. More accurately, her body is the nexus itself. In the course of her ascension, she erased her past and, thus, to continue existing, she had to transition into a form disconnected from the normal timeline, a body that contains a small pocket of her past in the form of her own memories and soul. Through this and her own perception of her power, her body has become essentially a walking physical expression of the fundamental force of Speed. This body is a magical nuclear power plant, constantly utilizing the forces of its own existence to generate and store further power, which is partially put towards generation, escalating the speed at which it generates more ad infinitum. This body doesn't possess an organic growth cycle and as a result is no longer is capable of aging.
As a result of erasing her own history/past, very few from her home-world recall her existence, and she has been relegated more to myth than anything. That said, she is not the only being that can step beyond the reach of time, and several that remember cultivate her (presently false) image as a Goddess and search for ways to contact her or bring her home.
