He couldn't believe it. He just couldn't believe it.
An angry snort escaped his snout and his fangs clenched harder at the sight of the familiar Pegasus who just glared down at him from the cloud she sat upon.

Her pink eyes and multi colored hair were easily recognizable from the two encounters he could clearly remember. The first time was when she and two other puny ponies had snuck into his territory and helped that runty, pony loving dragon escape. The second time was during his favorite sport. She had tricked....no no......cheated him out of the perfect surfing board and......was strong enough to throw a boulder at him.

A BOULDER!! What kind of pony was strong enough to throw A BOULDER OF SOLID ROCK back at him?! Without magic?!

He couldn't get over it. This called for a final show down. He had originally came here to challenge Spike for a final fight to finally settle things as Lord Ember suggested......Well, those weren't her exact words. After a few weeks of aggressive behavior and nonstop mumbling about ponies, Ember suggested (demanded) he'd go and get things straightened out between them. And instead of Spike, he found this rainbow maned mess of colors.

Her glare was returned in full. "AAAAAAnd what are YOU doing here?"

"None of your business!"

This made her scowl before standing up, stretching out her body, and jumping off the cloud. She hovered down until she landed in front of him. Giving a look that could crack diamonds.

"It is my business if you're here ta cause trouble. You dragons haven't really been 'hospitable' despite Ember making you 'make peace' with us."

"Gee. I wonder why? You invade our turf, disguise yourself as us, ruin my chances at becoming Dragon Lord, embarrass me, and steal my board!," he roared at her. The load volume made her wince.

"Wow. And I always thought Pinkie was the motor mouth. And I HAD to take it from you. Equestria was counting on it, and you only embarrassed yourself."

He growled before leaning down to point a claw at her. She failed to flinch. "You tricked me!"

She only glanced at it before smacking it away. "Only because you were so focused on winning that you didn't think things through. I used ta do it all the time. Rookie mistakes."

He snorted. "Whatever. I'm not here for you anyways." He attempted to step around her, only for her to block his way.

"Then what ARE you here for? It better not be Spike."

"So what if it is? It's none of your business."

"It IS my business is you want to hurt one of my friends!," she yelled pushing her face into his.

He growled and snorted before baring his fangs back at her. He'd be a filly if he let some bucking rainbow pony get the best of him. But still, she didn't back down or show any kind of fear. Instead, she bared her teeth right back and glared.

This continued for a few more moments before her face slowly turned into one of curiosity......then a sly smile. He watched her step away before giving him a grin.

"You're right."

He stared at her. ".......What?"

"I said you're right. Technically this is just between you and Spike, and none of my business. So why get involved?"

He stared at her for a few more moments before smirking. "Heh. Glad you finally got that through your head. Now outta my way! I got some unfinished business." He was blocked when she suddenly held up her hoof.

"Hold up. You still have business with me."

"But, you just agreed to stay outta it."

"Yeah. I said this-" She motioned to the ground. "-was just between you and Spike. But, you still have business with me, Rarity, and Twi."

"............Huh?"

She rolled her eyes. "Yeesh. Look. Like you said. The three of us invaded your turf, helped Spike, then Rares and Twi invade your turf AGAIN during the Dragon Lord quest thing. And then I supposedly tricked and embarrassed you later."

He crossed his arms. "And what are you suggesting? Ember said we couldn't harm ponies."

"She never said we couldn't have competitions."

".........I'm listening,"

"Let's have a little bet."

He hummed in thought. A chance to not only get back at one but all three of the ponies that crossed him AND Spike all in one day? It sounded too good to be true. Especially considering that look on her face. Then again, that boulder DID hurt.

"Exactly what did you have in mind?"

She raised a hoof to point at a tall mountain. "On top of that mountain is an old dragon's cave. First one there wins."

"What's the catch?"

She smiled wider. "If I win, you and Spike TALK your problems out and never bother us again."

"But if I win, you and those other two ponies get to watch me give it to him. And no one gets to stop me from doin' it."

"Fine. Then you'll do it?"

"Only because I know I'll win."

She shook her head. "Over confident much?"

He snorted. "Prove me wrong."

"Fine!" She turned and suddenly got into a cat like pounce position with her wings outspread and her flank stuck up in the air.

".........." He stared absolutely shocked. "WHAT ARE YOU DOING?!"

She stared back at him confused. "Um. Getting into the starting position for the race. What does it look like?"

"Sticking your rump up for everyone ta see!," he yelled flinging both arms to point at her flank. He paused for a moment before suddenly whipping his head away with an orange hue spreading across his face. "Have some decency and put it away!"

She stared at him. "Decency? You actually have the guts to talk to me about decency?"

"Look. Even I have standards."

She groaned. "If it bothers you THAT much, then just get over here so we can race. Unless, of course, you're gonna back out because of decency."

He growled before stepping around her, still looking away, and went to her side before getting down on all fours. An orange hue still present on his face.

"See? It wasn't that hard."

"*Pfft* Whatever. Let's just start this thing."

"If you say so." She looked back with a determined face. "On your mark. Get se-"

"GO!"

A sudden flap of wings was heard before she felt a whoosh of wind and dust was thrown in her face. She coughed and reared back before looking up. A red figure was winging through the sky.

"HEY!! That's cheating!" She flapped her own wings and took off into the sky after him.

Wind rushed past her as her wings beat the air. Carrying her higher and slowly closer to the red dragon. Luckily her smaller, lighter form was easier to zip through the sky than his bulkier form.

She was just a few wingbeats away from him when he must've sensed her presence because he looked over his shoulder and grit his fangs.

"Why can't you just give up already?!"

"HEY! You cheated and took off before I was ready!"

"Whatever! Why don't you go play dress up with that pretty rainbow hair?" He sneered at her scowl.

She looked as if she was about to shout something back.....but stopped and looked in front of them. Her eyes widened before she pointed a hoof.

"LOOK OUT!!"

He tutted. "Yeah. Like I believe-"

"TREE!!"

He whipped forward.......and yelled.

A tree (which was taller than all the others) was right in front of him. He flared his wings out like a parachute to stop himself. But, it was too late.
A large crash was heard as his body collided with the plant. Terrible pain course through him as he descended downwards. Branches snapped and broke under his weight. The last thing he saw before blacking out was the ground below.

......................................................................................................................................................................................................................

"Uuuuuuuuh."

A low groan sounded out. All there was, was darkness. Slowly, his eyes opened. All he saw was a colored mess. He bliked confused before he realized that it was hair.

Long hair attached to somepony's rump.

At first, he didn't do anything, but then an orange hue spread across his face.

".......Are you kidding me?! Get your flank outta my face!"

Startled, she whipped around and saw him awake.

".......Well, look who woke up."

"Shut it!.....Where am I?"

He looked at his surroundings. He was in a bed in what looked like a VERY clean room.

"The Ponyville Health Center. You blacked out after hitting the ground. You aren't easy to drag either."

"Well.......I demand a rematch!"

She rolled her eyes. "I knew you would say that. Look. The doc said you should be fine, but you have to rest for a while. You crashed pretty hard. And I don't want you hurting yourself more."

"*tch* What do ponies know?"

"I knew you would run into that tree."

"........"

"I DID warn you."

"Yeah, yeah. I still want a rematch."

She scowled before jabbing a hoof to his chest. "Alright, Buddy! Listen up! You are THE most impossible dragon I've ever met! You're rude, a cheater, don't listen, and overall a big JERK!!"

He winced from the loud volume. She just held her ground.

"But......I decided to be the bigger mare and help you out."

"I-"

"Was knocked out because you didn't listen. I made the same mistake."

".....Then if I'm a 'jerk', why'd ya even bother helping me out?"

"Because you DID show you had some good traits....And I wasn't just gonna leave you like that."

"What traits?," he asked raising an eyebrow.

"You not looking at my flank."

He froze.

"That shows you have SOME standards."

"......I-"

"Excuse me."

Both looked over. A mare in a white hat with a red cross looked at them from the doorway.

"I'm afraid visiting hours are over."

"Alright. I'll be right out." She looked back at him. "Better rest up. I don't want ya too tired when I beat ya."

"Heh. We'll see."

She smiled before turning and trotting away, but stopped in the doorway. "By the way....You might as well get used to seeing this." She wigged her high courters. "Because it'll be the last thing you see before I win."

She trotted away with a smirk on her face and a stunned look on his.

.......With an orange hue across his cheeks.
