*I don't own ANY of the Kingdom Hearts characters or How to Train Your Dragon characters, I only own Katie/Katie-Vanitas

"Well, are you just gonna stare at me all day or take down that dragon, chump?" Katie-Vanitas sneered.

Riku still couldn't believe that Katie was Vanitas…or Vanitas was Katie…man, this is confusing! Was Katie really this deep in the Darkness; to have Master Xehanort's former apprentice control her? He shook the thought away and sighed, "You better not be up to any tricks, Vanitas…"

Katie-Vanitas chuckled darkly. "Trust me; if I was…" she leaned closer. "You and your little friends would've been dead a long, long time ago." With a devious grin, she dived down to Green Death before Riku could respond. Hiccup went beside her; Katie-Vanitas looked at Hiccup and nodded at him. "Let's see what you and your dragon got, runt!" Hiccup and Katie-Vanitas both looked ahead and dived at incredible speed. Toothless opened his mouth and the inside glowed blue while Archraven screeched and glowed a deep red. They were going so fast that the familiar whir of the Night Fury rang through the sky.

"Night Fury!" someone yelled from the ground.

"Get down!" added another Viking.

Toothless let out a massive blue fireball from its mouth and it snoozed towards the Green Death. Right before impact, Katie-Vanitas jumped off of her Archraven and plummeted to the ground. The massive beast was knocked over by the blasts. Toothless flew quickly underneath Katie-Vanitas and caught her. "What were you thinking, Katie?!" Hiccup yelled.

"For the last time, I'm not Katie! My name's Vanitas!" Katie-Vanitas growled. She shrugged, "I used my Unversed to ram into that thing. It's the only thing it can do right, run into things." Her eyes widened as she yelled, "And…YOU MIGHT WANT TO LOOK WHERE YOU'RE GOING!" She made Hiccup look back forward by grabbing his jaw and turning his head forcefully.

All Hiccup could see was mountain. "Oh, gods!" He pulled up and around before they became part of the mountain. Shaking off the scare, they circled the fallen Green Death. "That thing has wings…" Hiccup said to himself. "Okay, let's see if it can use 'em! Up, Toothless!" Toothless soared high into the air then folded in his wings, plummeting at the speed of sound towards the giant Heartless dragon.

"If you don't mind, I'm going to make that fireball of yours a bit bigger…" Katie-Vanitas told Hiccup with a smirk.

"Huh?"

Katie-Vanitas rolled her eyes. "Just wait and see, runt." She wielded Void Gear and pointed it at the Green Death. "Ready when you are."

"Fire, Toothless!" Hiccup commanded his dragon. Toothless unloaded a fireball towards Green Death's head.

"Suffer!" Katie-Vanitas yelled. A large, dark fireball exploded out of Void Gear's tip. It merged with Toothless fireball and, like Katie-Vanitas said, it grew larger and more dangerous. The fireball exploded against the giant Heartless' head and knocked it back to the ground. They climbed back up.

"You think that did it?" Hiccup asked Katie-Vanitas over his shoulder. Katie-Vanitas nodded in an all-knowing manner. They looked back down at the Green Death to see it slowly unfold its wings and extended. Hiccup was surprised when the giant Heartless flapped its wings furiously as it rose from the ground and after them with impressive speed for its size. "Well, he can fly." He stated bluntly. He took Toothless to tangled sea stacks and weaved through the columns of rock to see if he could lose the Green Death. The Green Death snapped at their wake but was unable to reach due to Toothless' sound-like speed. Hiccup pulled Toothless up. That didn't stop the monstrous beast. It smashed through a canopy of rock and closes in on Toothless. They didn't notice that they were over three-hundred feet above the ground.

Stoik, Gobber, the teens, and Keyblade wielders watched as Hiccup, Toothless, and Katie-Vanitas weaved through the sea stacks. They all cheered the Viking and the Master of Void on but their hope died down when the Green Death smashed through the sea stacks, turning them into dust.

In the air, Hiccup realized there wasn't anything that he or Katie-Vanitas could do to slow the beast down. He eyed the clouds above and an idea struck him. "Okay, Toothless, time to disappear!" Toothless pulled into a steep climb and into the layer of thick storm clouds. The Green Death closed in on them. Hiccup heard the hiss of gas form from the large Heartless' mouth. "Here it comes!" He yelled. A large blast of hot flames shot by their wake, they barely dodged. They punctured through the low layer of clouds and disappeared. Green Death looked around angrily for the dragon and its riders as it roared furiously. From out of nowhere, Toothless dived out of the clouds and blasted a fireball at one of its wings, puncturing a hole. They disappeared before the Green Death could attack.

The Vikings and Keyblade wielders stared up at the sky listening to the resounding booms and watched flashes of orange light burst through the clouds, making them only see the dark outline of the Green Death. Repliku felt fear grow in his chest, will he lose another friend like he did long ago?

Hiccup, Katie-Vanitas, and Toothless dived again and again, shooting fireballs and ice shards at the Green Death's flank, using the clouds to hide and use the element of surprise. Furious, the Green Death bellowed and whirled around while it spewed fire in every direction blindly.

"Watch out!" Katie-Vanitas yelled. A random line of flame hit Toothless' makeshift tail, burning it slowly to a crisp.

Hiccup looked over his shoulder and his eyes widened at the damage. "Okay, time's up!" he voice was shaking with worry. He pulled Toothless up and to a turn. "Let's see if this works…" They flew directly into the Green Death's face, taunting it.

"Come on, lizard breath! Is that all you got?" Katie-Vanitas sneered. Toothless uttered an insult too, and they jackknife into a steep dive. The Green Death pursued closely. Toothless pumped his wings as hard as he could, racing faster than he's ever gone before. Hiccup, Katie-Vanitas, and Toothless stay just ahead of the Green Death—no longer evading it. Katie-Vanitas looked over her shoulder to check Toothless' tail, it was disintegrating. "Okay, runt! You better wrap this up, that tail isn't gonna last any longer."

Hiccup nodded and patted Toothless neck. "Stay with me buddy. We're good. Just a little bit longer." He told his reptilian friend. The Green Death closed the gap. Hiccup and Katie-Vanitas tucked in and hold Toothless steady - allowing the monster to set its sights on. The monster narrowed its eyes. "Hold, Toothless." Green Death opened its mouth. The familiar gas hiss emanated from its throat, ignition was coming. "Now!" Hiccup yelled. Hiccup hit the pedals hard as Toothless extended one wing. They pivoted in place, hurtling directly into the Green Death's mouth. Toothless and Katie-Vanitas fired point blank down the monster's throat. The monster's amassing gas ignited, backfiring into the monster, erupting in a chain of blasts throughout its body.

Hiccup, Katie-Vanitas, and Toothless burst from the clouds, the Green Death hot on their tail, exploding from within. It glanced forward and sees the ground rushing up. It threw open its wings, attempting to put on the brakes, but the punctured, damaged wings can't stop its momentum. As the Green Death choked on the expanding fireball, he sees Toothless suddenly pull out of the dive, streaking up, past its head. The Green Death crashed to the ground headfirst, exploding on impact like it was a Nuclear Bomb. Hiccup, Katie-Vanitas, and Toothless weaved through the monster's massive back plates, wings, and flailing legs - a high-speed recall of the free fall slalom run. The expanding fireball raced toward them, about to swallow them. They manage to clear the obstacles.

Hiccup glanced back. They're outrunning the fireball. He looks forward just in time to see the monster's massive club tail careening toward them. He tries to shift their direction. The last shreds of Toothless' tail tear away. Hiccup's pedals go dead. "No…no!" he yelled as the tail got closer. Everything went black.

Katie jerked up in a cold sweat to her alarm clock. She slammed her fist on the annoying alarm clock to make it shut up…wait…alarm clock? She slowly sat up and looked around. She saw the very familiar line of mini Harry Potter posters around her bed and a Heartless plushy. "I'm in my room…I'm in…my room…? It was all just a dream?" She ran her fingers through her straw-like hair. "It can't be…it couldn't be…!" Katie threw her sheets back and climbed down her loft bed's ladder. She looked at her clothes. Checkered pajama bottoms and a see-through light blue cammie. Katie reached out her veiny, boney hand and closed her eyes. 'Come on…come on…' No Keyblade appeared. Katie opened her eyes and let out a confused sigh. "Was it all just a dream…?" She walked out her bedroom.

Katie was amazed to see her kitchen untouched and there were no shotgun shells scattered across the floor. Katie mentally smacked herself. It's official. She's crazy. Then an idea hit her. She ran to her bathroom and turned on the light. Because she doesn't have her glasses on, she leaned on her counter to see herself in the mirror. She blinked to see only light brown hair and blue eyes. She rubbed her eyes and blinked at her refection. "No silver hair? No gold eyes…? So it was all a dream…" Katie walked back out to her kitchen and opened a cupboard; she reached in to grab a can of Friskies. Opening the can, she called, "Venitas! Ooooh, Venitas! Here kitty, kitty! Mommy's got breakfast for you!" Her cat didn't come. Confused, she set the can down and walked around her house to find her cat. "Venni? Oh, Venni…! Where are you…?" she stopped at her curtains. Something didn't feel right. Slowly, she grabbed her curtains and pulled them open. She clamped her hand over her mouth from what see saw. Outside the window were no longer green grasses, the grass lost its color and was dead. There was no sun. The bright blue morning sky Katie was used to was replaced by swirling grey clouds. The tree's had no leaves and were grey; dead. Katie's mind spun. What the hell was going on?!

Confused bros? O3O
