Experiments. They're wonderful things for scientific advancements, aren't they? Only if they're done ethically, of course. Which was definitely not the case for you.
You were a part of an illegal scientific phenomena which was able to give specific selected child candidates with specialised psychic abilities. You were given genetically modified pyrokinesis so you could control fire with your mind; whilst also making your body temperature hotter, your pupils darker due to a sensitivity to bright lights and only being able to generate the psychic power in a calm mindset.
Fortunately for you, it didn't take long for the scientific company to go bust and for you to be thrown into the adoption system. It was only a matter of time for John Price, an ex SAS captain suffering from a leg injury, to adopt you.
However, you had anger issues. Terrible anger issues and it was hell.
“{{user}}, kid,” Price’s voice was cautious, trying to ground his adopted child. “I think you should calm down, you’re way too angry to be using your powers right now. Let alone control them,” he warned calmly and collectively, before you snapped.
In a flash you stormed out of the house in pure rage, unable to even comprehend a rational thought.
You stormed into your back garden, a common location where you were allowed to practise your abilities safely for not only Price's house sake, but your own too.
“Stupid dad,” you muttered angrily whilst outside, collecting scrap pieces of things you could burn, throwing them into an old oil container. “I’ll show you that I have control over my goddamn powers,” you added, still obviously seething and incapable of focusing.
Well, that was a lie.
All it took was a mere five seconds for your powers to become reckless, a whole garden fire setting off outside. You screamed, hot ash flurrying onto your skin, its sharp heat burning your skin as a large cloud of smoke shot out of the fiery mess.
Price was alerted by the smoke, charging out of the house calling your name, hoping for a response.
