This is the OC's background story. I did not write this at all. Please give positive credit to Corrosive Dash for producing such a great background story in the nick of time.

…

A stallion sat astride a burning earth hound tank, looking towards the hills where the victory gaining explosion had come from. He stared towards it with his glowing yellow eyes and pondered the meaning. Surely it was an omen, and the possibility of his sister being near sent his heart racing in his chest. The smoke drifted calmly around him.

He was named Corrosive Dash, elder brother of Rainbow Dash, and he was twenty three years old. He idly scraped at a long and razor sharp canine with a hoof capable of penetrating steel. He looked towards the fleeing earth hound forces as they were chased by the armed zebra tribestallions and E.N.G. forces alongside them. He had been integral but really the sonic rainboom made the difference, it had startled all but no ally of the dogs could do such a thing. As such they were demoralized and caught off guard when the ponies broke from their stupor and attacked with renewed force. The starlight gleamed off his blood stained red scales and reflected in his neon eyes as he thought back to the events leading to this point in time, this opportunity to reunite with his beloved...

Twelve years ago...

“You stay here and don’t come after me you freak!” That was his mother, Sunny Skies.

“But- but mom! I don’t wanna stay here! I won’t last a day on my own! Please don’t leave me here!” He cried. Why was she being so mean? Why did she look so angry? What had he done wrong?

“You know why I’m leaving you here?” She hissed venomously.

“Please! Tell me what I did wrong mommy! I’ll make it up to you I swear! I’ll do the dishes, I’ll take out the garbage, I’ll clean my room, I’ll even stop beating on Soarin when he comes over even though he’s a pervert!” He pleaded while falling to his belly and grabbing her knee. He began to cry pitifully. He hoped she would relent and let him come home

with her.

She shook him off callously before snarling, “You f****** corrupted your little sister is what! How could you Corrosive? She. Is. Your. Sister! You are to protect your sister, you are to look after your sister, and yes you are to love your sister! But you! You are sick! I saw what you two were doing! Brother and sister should never mesh tongues you sicko!”

She sneered at him, “I’m leaving you here to protect our only good child from your foul influence. I won’t have her brought down by the likes of you. You are never to return home and will never see her again.” She proclaimed and

leapt into the sky.

“Nooo!” Corrosive cried as flew after her desperately. He couldn’t stay out here, he couldn’t never see his sister again, he loved her more than life itself! She was losing him, she was bigger and more experienced and therefore faster. However he was smaller and thus more agile, he could also go where she couldn’t. She went around a great web of thorny vines, to abandon the path she had used was potentially death in the Everfree, especially this deep in where the trees turned day into night. Corrosive went through the airborne hedge and though he was cut and scraped he burst through the end before his mother and

grabbed onto her neck.

“Get off you cretinous scum!” She yelled before slamming him into a branch overhead. He fell, breathless, to the earth. He gasped for air and watched his mother’s form vanish through the trees. He passed out from pain and exhaustion moments later.

Two years ago...

Corrosive looked at the ill dragon and felt pity. It looked sick, like it was dying even. The sight of the magnificent red being brought low stirred old sadness in his own heart. He had survived despite his claim all those years ago, thrived even. He was lean but he was pure muscle and could lift twice his weight with ease. He was tall, as tall as the average Royal Guard though he didn’t know. He had not seen a mirror or compared himself in a long time. His fur was red like blood and his hair was hues of black and yellow, cut short and messy with improvised knives. The local predators left him alone now, hanging their brethren’s skulls from the branches of his home tree might have had something to do with that. The ones that might have preyed on him gave his turf a wide berth, the ones too small to be a threat were ignored, and the ones too huge for him to stand a chance against ignored him as it wouldn’t be worth the effort invested to catch the speedy stallion.

When he lay in the boughs of his claimed home he thought of his precious sister and almost wept. He’d hardly a clue what she looked like, he only hoped she still had her beautiful rainbow mane. He imagined her beautiful cyan fur and her amazing pink eyes. He still loved her. In fact his love for her had only grown with his miserable isolation. He’d tried to find a way out from time to time but always returned to the place he knew lest he become lost and encounter something he couldn’t escape from or fight off.

Looking at the dragon he felt pity. He had seen other dragons but never one like this. He had seen this one before too. Always alone, even as he lay dying. It reminded him of himself. Corrosive made the decision and approached his fellow outcast. He approached the beast with its greying scales and heaving chest. He came around its side to within sight of its pained eyes but unfortunately in range of its limp tail.

“I mean you no harm friend! I only wish to hel-” He said in his rough voice, unused in who knew how long, before he was impaled in the flank by its formerly limp tail. It impacted just behind his left wing and he fell without a sound, he never even got to scream. He twitched in place, his eyes open wide and his mouth frozen shut. The soulsplitter dragon gazed balefully into his eyes as it grinned painfully. Then the flood of memories hit and its eyes widened. Such pain, such love, so alone...

He decided that his last actions in life would not be to selfishly extend his own life by perhaps a year. Instead he would give this lonely stallion a gift, he certainly deserved it for all his pain.

As the remnant of the dragon’s soul surged into him the dragon looked into Corrosive’s eyes and spoke, “This is my gift to you Corrosive.” Then he ripped his stinger free and turned into ash. Corrosive stared for a moment before making a final twitch and falling unconscious.

One year ago...

Corrosive slammed a hoof into a rocky cliffside. His hooves were tougher than steel but he scarcely noticed. He was covered in tough red scales in place of fur but he didn’t really care. His wings were twice the length of his body but it barely registered. His teeth were tougher and sharp like a dragons but it didn’t matter. He was tall enough to look a pegacorn on eye level without taking flight but he didn’t even know that. He dreamed of his sister every night now. Sometimes he woke up drenched in sweat and screaming her name. He knew he had an obsession but it was all he had, so he didn’t try to curb it. He went further in his attempts to find a way out of this accursed forest but failed all the same. He hated like few others.

Two months ago...

He did not struggle as the alicorn held him against the tree. He had learned in his life when to back down. Life in the Everfree was tough, tougher still for a mere pony. Almost certain death for a yearling. You had to be both smart and strong to survive and Corrosive Dash was both of these things. The three alicorns had flown into his territory and, upon spotting him, slammed him into a tree with their magic and vigorously scanned him. When they were done they released him and he slid down the tree. He rose to his hooves and glared warily. He might have attacked despite knowing it was suicide but they had not truly harmed him and he refused to succumb to the lure of the wild. He refused to let the Everfree turn him into a violent murder machine, refused to become a monster.

“We apologise sir. We are hunting a monster that recently escaped captivity. It has the ability to mask its true appearance so we must examine all things we find suspect. We would advise you to evacuate as it has already ravaged two cities and has a taste for pony flesh.” A mare with teal fur and a mane like liquid emeralds advised as she spread her wings.

“Wait! I’m kind of lost, could you maybe point me in the right direction?” He asked while nervously smiling. He did not remember his razor sharp teeth and as such his attempt at friendliness looked terrifying. The alicorn was not impressed, she had seen worse.

“Follow this light.” She ordered and conjured up a purple light which hovered in place momentarily before flying off.

“Thanks!” Corrosive yelled as he took off after the light.

Present day...

Corrosive finally ventured out of the Everfree forest, but he felt a little sad leaving the horrible place. He followed the dirt pathway to the nearest town but halted by the sound of laughter? But the laugh he heard was strangly familliar. He trotted toward the laughter and disovered something he though he would never see again, his sister. Corrosive was about to call out to her until he spotted a being he never seen before, it stood on it's hind legs and it was laughing, more importantly with his sister. He felt rage build up inside him but seeing his sister so happy broke his heart, he huffed and trotted toward the two thinking to himself,"I hope she remembers me..."
