Interlude: When it comes to the harsh winter cold and power over ice there are numerous cryomancers out there such as Weiss Schnee from RWBY,  Sub-Zero from Mortal Kombat, or even  Frosty the Snowman. But these two are pretty much made for each other, seriously just ask the fandom.

Backstory: Eons ago it was the Golden Age, the Man in Moon had a friend named Nightlight who watches over him. Together they sailed on a ship called the Moon Clipper.At night when the Moon Clipper turned into a moon, Nightlight sprinkled Dreamsand over MiM and sang him a lullaby. As MiM slept, Nightlight watched over him keeping him safe from nightmares. But Pitch heard of him, a boy who had never had a nightmare, and decided to make that boy his Prince of Nightmares. MiM's parents decided to hide on a little planet called Earth but suddenly his family was attacked by Pitch, The Nightmare King. MiM's parents commanded Nightlight to take the baby to a hidden nursery in the ship, but only after taking the oath. Nightlight did as instructed and rushed MiM to safety, the Moon Clipper rocked as the battle continued. Knowing what to do next, Nightlight told MiM to remember him in his dreams, before he went to battle Pitch. Nightlight aimed the dagger at Pitch's heart causing a blinding flash followed by a great explosion. After the battle, MiM found himself alone on a small moon, revolving around the planet called Earth. Twice he called, and listened but no answer came from his parents. In the sky, he noticed a group of new star shimmering above him. He stared at them until he was able to see his parents in this new constellation. Wondering about Nightlight, MiM got a glimpse of a Shooting star as it fell to Earth. The remaining Moonbots, Moonmice, and giant Glowworms surrounded and carried him into the tunnels of the moon to keep him safe. Every night, MiM flew on the back on one of the , until he was able to see his parents' constellations. He then went to sleep and dreamed about Nightlight and the Golden Age. As time passed, the moon became his playground and every meal was lit by a school of Starfish. One day, he found his mother's book and remember something he had completely forgotten about. He ran to his father's telescope and spotted the little planet called Earth. To his surprise, he found that Earth was inhabited by children just like him. Years went by, and MiM wasn't a child anymore. MiM decided to keep a watch over the children of Earth, and he discovered that if he held a balloon to his ear, he could hear the hope and dreams of the children. MiM learned that sometimes the children just needed a toy, candy or a prize to cheer them up, but he also discovered that they were still scared of the dark and were having nightmares. Mim vowed to never let their dreams be invaded by Pitch's nightmares and decided to call to his side, a band of heroes to serve as The Guardians. Years later there was a kid name Jack and he was the most the funnest guy around until one day he fell into a frozen lake when he saved his sister with fun. He was soon reborn into a new being called Jackson Overland Frost or Jack Frost for short and he got amazing powers of all things ice with the downside of being not noticed by the people around him and that's his life for 300 years until one day he was chosen to become the Guardian of Fun and protect the children of the Earth.

Stats(Strength and Durability):

-Nightlight Scaling

>And since Jack Frost is the reincarnation of Nightlight he should scale to this

>131.1 x 20 = 2622 tenatons which is Large Star Level

Final Verdict: Large Star Level

Stats(Speed):

-Tooth Collecting

>In the movie, Tooth lost all of her fairies by the hands of Pitch Black and the Guardian's have an idea so crazy it just might work. They collect the teeth themselves, using the distance Santa travels in one night which is  212825847.053 miles and since they forget to leave gifts that has doubled.

> 212825847.053 x 2 = 425651694.106 miles

>Which took 3 minutes and according to Tooth.

>Tooth: Wow! You guys collect teeth and leave gifts as fast as my fairies!

>Which is 8,513,033,882 mph or 13x the speed of light

>If they remembered to leave gifts for the kids

-Scaling to the Guardians of Childhood

>Tooth can fly at speeds of Mach 96 which is High Hypersonic+

>Bunny on the other hand can run at speeds of Mach 5905 which is Massively Hypersonic+

>It's been stated that Sandy can casually go all over the universe which is Massively Faster Than Lightspeeds

Final Verdict: Massively Hypersonic+ to MTFL in reaction, travel, attack, and combat speeds

Weaknesses:

-He sometimes slacks off, and his powers are much weaker without his staff

-Becoming invisible and intangible is a double edged sword

>Only works on normal people and not people like Pitch Black or Tooth Fairy

>People have to lose belief in him

Battle

--------------------------------------------------------------------------------------------------------------

Here we see a blizzard in Arendelle and we see Elsa looking for the cause of it.

Elsa: "Someone has to be doing this, but who could have-"

We then see a snowball hit Elsa in the face and she brushed it off and saw Jack Frost.

Jack: "Haha! Man, snow days are the best days."

Elsa: "You did this?"

Jack: "Yeah, pretty nice right? Snow days are fun."

We then see Elsa use her power to get rid of all of the snow as Jack saw it happen.

Jack: "Oh come on, I worked so hard on this snow day."

Elsa: "The last time there was a snow day here, it was a disaster and I nearly destroyed the kingdom."

Jack: "Oh come on when will you have some fun around here, man you're so uptight."

Elsa: "I'm warning you, leave Arendelle or-"*gets hit by a snowball from Jack*"That's it!"

We then see Elsa unleash a powerful wave of ice at Jack as we see him dodge it.

Jack: "Okay, guess we're doing this then."

We see Elsa shoot ice at Jack as we then see her make walls of ice so that she can hit him with them as we see Jack unleash blasts of energy at Elsa as she blocks them with her ice walls and then she makes gigantic Marshmallows to attack Jack as we then see him destroy the Marshmallows with powerful ice beams and then we see Jack hit Elsa with his staff multiple times as we see Elsa shoot an ice blast at Jack as we see him get up from the blast as we see Jack made an ice slide under Elsa's feet and made her slide into a pile of snow. We then see Jack stand on his cane and we see Elsa get out of the snow.

Jack: "Haha! Man, that was fun don't you think?"

We then see Elsa get angry and burst out of the snow and starts firing ice at Jack as we see him launch ice blasts at Elsa and she launches herself into the air and shoots ice blasts at Jack as we see him dodge them all. Elsa then unleash a powerful blast of ice at Jack as we see Jack's Staff glow white and unleash a powerful blast of his magic and the blast was too much for Elsa to handle and she was frozen solid as we see a concrete cup fall from the roof and when it landed on Elsa, she was shattered into a millions pieces as Jack then land next to her head.

Jack: "Okay.......did not mean for that to happen. I'm just gonna go."
