A time travelling alien whose history was constantly being rewritten. Neila was yanked out of her time forcefully, and temporal energies flowed through Neila, which caused her to develop new powers every week.
The energies however have given two consistent abilities. The first is that she can teleport by briefly travelling through the time stream. This causes her age rapidly, or it would if her the other ability wasn't immortality.
Fluctuating Powers and Past Lives
With each new set of power came a new incarnation of Neila Flux. Her first incarnation was that of a savage creature who escaped from a laboratory. It was here that she got her name, with it being a combination of the first word she saw (the word 'alien' on the opposite side of a glass door) and heard (from a scientist mentioning the 'flux of energy' on their scanner). Her other incarnations include a void-shaping magician, a martial arts master, a storm elemental, and a Malvan gladiator with a sword similar to Ironclad's.
She has since managed to stabilise her timeline and her powers after a confrontation with the one who threw her into the time stream in the first place. He threw into another portal, but this portal sent her through the Multiverse. She returned a day later, but it had been decades for her. In that time she had learnt a considerable amount of magic, which she used to remove the temporal energies from her body, and become a protector of all reality.
Neila Flux's nemesis is Chronosapien, an Az'arc'a energy being from the future, whose real name roughly translates to "Burning-Blue-White".
"Burning" stowed away on the time machine of a passing time traveller called "The Fashionable One", where he analysed the technology so he could copy it a build his own. He built a machine that managed to form a time vortex and thought "I wonder what would happen if I throw a living being into there?". He travelled to a remote planet, kidnapped a local lifeform, and threw her into the vortex.
"The Fashionable One" found out about "Burning",who was now calling himself Chronosapien, and proceeded to exile him to 21st Century Earth in suit that would both protect both the citizens of Earth from Cronosapien's brightness, and protect Chronosapien from the Earth's gravity. Chronosapien hopes to get revenge on the fashionable one, but for now will settle for the one he threw into the vortex: Neila Flux.
