Nightmare Moon Vs The Lightbringer
A child is seen getting up in an age range between fourteen and fifteen, he was a light skinned human with black messy hair, a long black vest with white trims, a steel colored long sleeved shirt, and on the back of his vest was the deltarune symbol. He also had black baggy pants and a katana with the Deltarune etched into it. He groaned as he traversed the forest and looked around in the process. This is Marcus, a young lightener. What is a lightener? Well, Lighteners were once the protectors of the Darkners, before they left them alone in the shadows. Lighteners were seen as the "Gods", "protectors", "creators" and "those who gave us purpose" by the Darkners. One day however, the Darkners were locked away in the Dark World, and the Lightners were never seen by them again. But somehow, Celestia, Luna, and a few others were visited by these beings and a legend was when one were to come to Equestria, would be crowned a king. Marcus then heard rustling in the bushes and then suddenly, three wolf like creatures leapt at him.
(Cue Rude Buster)

As instinct, he pulled out his katana and struck the ground, causing the wolves to jump back as he kept his guard up and sword up.
“Ok What the hell…” Was all Marcus said as he got a better look at the things. It looked like they were made out of wood, logs, twigs, and branches. Marcus decided to try and talk things out.
“That flower on your left ear twig is beautiful.” The timberwolf didn’t understand what he said, but was flattered anyway. The flattered timberwolf doesn’t want to fight anymore, so Marcus came over and scratched it behind the ear as it ran into the forest. The two others did not step down and tried to bite him. He then twirled his katana and struck the timberwolf hard to cause it to run away. The other looked afraid as Marcus shooed it off. Marcus then put the sword back in its sheath. He walked a bit forward to see a medieval castle. He then saw a shadowy figure graze a window. He gulped.
“Stealth Mode, don't fail me now…” He said to himself.
As Marcus traversed the hallways, a shadow had been stalking from behind.
“A Lightener?” The shadow said as he continued to walk casually. Whistling the scarlet forest theme, the shadow gazed at the boy’s young appearance, so carefree and innocent. A wicked smile spread across its face as it then materialized in front of the teen and he stepped back in surprise.
The creature strutted forward, its high heels clicking sharply across the old weathered floor. Its skin was actually a sleek black fur, garbed in a revealing dress that left little to the imagination. Her eyes narrowed as she sized the lightener up. Yet the being did not make a move. Simply watching an enticing smile on her lips.
His expression changed from surprise to neutral expression. He then spoke.
“Excuse me but what the fuck are you?” She looked annoyed and a bit angry but composed herself.
“Such a foul mouth for a tiny little lightener.” She said “I only was going to offer one thing to you.” He raised an eyebrow.
“And that is?” He ushered her into the spotlight.
"How would you like to join me in my crusade, we can rule the night together as... Queen and King!"
“See here’s the problem with that. One, causing eternal night would cause a fuckton of damage and most likely the extinction of some races. Second, No.” He stated plainly.
“It looks like you don’t know your place. I AM NIGHTMARE MOON!”
“...Shut the hell up.” Marcus stated plainly as she lunged at him. He pulled out his katana and struck the ground, causing her to recoil back.
(Cue Chaos King)

She shot a magic blast at him, he dodged, narrowly avoiding it as a thin white outline of a heart flashed a bit around his figure.

He then decided to spin his katana around as it in a brief flash, turned into a shield as she shot another blast at him, it hit the shield with a bit of force that made him stumble back a bit.

He had enough energy to unleash the rude buster as he grinned at her. He then raised his sword up as it had a green hue to it as he then closed his eyes and swung his sword forward as arrow looking projectiles were shot out of the sword along with a guitar sound effect played. It hit her as she was sent flying back.
“WHAT DID YOU JUST DO?!?” Nightmare screamed.
“That was Rude Buster. You like?” Marcus wiggles his eyebrows. She teleports and shoots a magic lightning bolt at him. This caused mortal damage, causing him to fall on the floor. She slowly walks her way to the young lightener.
“THIS is what the legends and my sister said had unimaginable power? Pathetic… but I believe you are more than you seem to be. So will you join me?” Marcus lets out a weak chuckle.
“Go… fuck yourself…” her left eye twitched as she used all of her willpower not to smite him where he laid.
“Let me tell you something child,” She picked him up by his head “rude people piss me off.” She said menicanly. With magic she twisted and broke his ribs, causing him to grunt in pain. But deep within him, a light resonated from his soul: It was HIS POWER.

His soul popped out of his chest as it blasted a very huge and powerful so potent magical blast, that it caused Nightmare Moon to be shot back with such powerful force that it broke nearby stone slabs and slammed her into a wall. He then blacked out.
