Hi All, this is my First Fanfic, I hope its ok :), I recently saw the movie and this idea came to my head, so I decided to write the story, its most likely to turn into a sort of Jack/Jamie, though it may not, depending on where the story takes me.

I Think I may have made Jack and my OC's Overpowered slightly.

Anyway enough from me on with the story!

Chapter One: Jack's rest.

It was his time off, that was what 300 Year old Jack Frost decided, he had Bright White hair, Blue eyes and wore a Blue Hoodie that had small pieces of Frost on his shoulder and Grey trousers. This time of year, only the hot countries were in winter, none of them ever got snow or Ice, so he had nothing to do, he decided to read up on other spirits that exhibited the world, like cupid or Jack O' Lantern.

He was just getting into a interesting Chapter on Season spirits when he heard a knock at the door, he got up, expecting it to be North or Bunnymund, here to tell him off about not working but instead on the doorstep he found a 18 Year old Girl, hands on hips. She had Bright Gold Hair and Green eyes both seemed to spark with power.

"Who are you?" Jack asked, frowning at her,

"I am Rosa Summers, Spirit of Summer and you are Jack Frost, Spirit of Winter" Rosa told him,

"Right, would you like to…" Jack was about to ask

"No, I Am here to challenge your Guardianship, through the Ancient Rite of Matlelel Tebnt!" Rosa told him.

"Martlele Tebnt?" Jack asked curiously,

"A Battle between us to determine which is more powerful, the Winner shall either Remain a Guardian or gain the loser Guardianship, while the loser is sent far away, to die" Rosa told him, "Oh and did I mention the best part?"

Jack scowled, not liking what was coming.

"Every Guardian needs to watch, so when you lose, they will all see you be defeated…. And possibly even better, you need to accept its part of being a guardian" Rosa smiled.

"Fine, Tommorrow then at Sun-rise" Jack frowned, he needed advise, quickly.

"Agreed" Rosa told him walking off, "You better pack you things Frost, when I fight, I fight to win"

With that Rosa vanished in a flash of Golden light, Jack took his cue and grabbed his staff, flying off towards North's Toy shop, as he flew he remember the glimmer of pure power in Rosa's eye, he didn't know if he could match that.

He landed gracefully outside the front door and tapped it lightly with his staff, though it froze over, the door swung open and Jack walked inside, looking around, the Elves and Yeti's were walking around most working though some seemed to be there for the sake of being there, in the centre he saw North, A.K.A Santa, Father Christmas, St. Nick or whatever you want to call him, he wore a red coat which hid most of his giant form and has a large white Beard.

"Jack!" North called out in his Russian accent, Jack waving to him slightly, "What brings you all the way here?"

"Trouble" Jack replied, "I got challenged to a Martlele Tebnt, at least that's what I think its called"

"Who by?" North asked rushing to the alert button.

"The Spirit of Summer, Rosa Summers" Jack replied, and North slammed his hand down on the large button, sending the signal to summon the other guardians.

"Then you are in danger" North told him,

First to arrive was Tooth, the Tooth Fairy, half Humming bird, half Human she flew in through the door to see North standing with an (Extra) Pale looking Jack, "What's happened North?"

"I'll explain when we're all here" North told her she flew over to hover next to Jack.

Next to arrive was Sandy, the Sandman, he flew in on a Golden Plane and landed down looking over at North, Jack and Tooth, a Question mark appearing over his head made of Gold Sand.

"In a minute" Tooth told Sandy who nodded and jumped next to North, looking at his Face, where a slight trace of Panic had appeared,

Last to arrive was Bunnymund, the Easter bunny. He was tall and wielded two boomerang's, "What up Mates?" He asked with an Australian accent.

"We have a problem, a threat to a Guardian's Guardianship" North told them,

"What!" Tooth exclaimed falling to the floor,

"Who's?" Bunnymund asked,

"Young Jack's" North told them, "From Rosa Summers"

"Rosa?" Bunnymund asked, "You mean the Spirit of Summer?"

"Yea" North replied,

"What can we do?" Bunnymund asked,

"We all need to be there, Jack listen she may be older than you, but your stronger and quicker, so use it to your advantage" Tooth told him,

"I Will" Jack nodded, they continued to give Jack hints and tips including to watch where he stood, as she often laid traps on the floor for her opponent to be blasted backward, they all knew how hard it was to hurt an Immortal, but both contestants could do fatal damage to each other.

Much Later as Jack was sent to rest, so he'd be at full power for the battle, he started to remember the only other time he'd Fought, 10 Years ago, Against Pitch.

As he remembered this he tried to remember how to cast all his spells. He smiled, he would try and make it as fun battle as he could
