The Blue Guardian

Undertale & Rise of the Guardians Crossover

Summary: The Boogeyman has returned and he's stronger than ever. However, there's one tiny problem. He's not alone. Of course the Guardians are there to stop him. But they're not strong enough. A new Guardian is chosen to defeat the beings of fear and determination. But he has given up on fighting.

The Ruins

(A/N): Contains spoilers! I suggest you either go play Undertale or watch Rise of the Guardians before reading.

Undertale belongs to Toby Fox and Rise of the Guardians belongs to William Joyce.

Jack landed softly on the ground, like a snowflake. He had finally arrived at Mount Ebott. There wasn't many Humans here, he noticed. Just a small village. Jack walked until he found the cave. He paused for a second, carefully thinking his plan over before casually shrugging with a nonchalant look, entering the cave. The first thing Jack noticed was that it was dark, very dark. For a second, Jack feared that the Boogeyman would find him here. After all, darkness was where Pitch dwelled. But after a moment, Jack swallowed his fear. He had to be brave. What would the Guardians think if he couldn't do a simple job? Jack continued walking, that is, until a vine wrapped around his ankle, tugging him rather harshly. He landed flat on his face, almost dropping his staff, but he fixed his grip on it as he tried to grasp something with his empty hand. It was futile. He was dragged across the dirt, rocks scrapping at his clothes and skin, until Jack felt his world give way underneath him. Jack called for help…

But nobody came.

Jack awoke with a start, gasping loudly. He quickly stood up, brushing the dirt off his clothes. Jack's staff lay on the flowerbed that he apparently fell on too. He quickly snatched up his staff, gripping it tightly. His eyes darted around the small area, searching for any sign of that dreaded vine. But Jack found nothing. He let out a sigh of relief. He slowly walked forward, entering another area. It looked empty at first, so he entered without a second thought. That was a big mistake. A small golden flower popped up out of the ground. It looked too happy. It had a white androecium, six golden petals, and a green stem. It introduced itself with lots of enthusiasm. "Howdy! I'm FLOWEY. FLOWEY the FLOWER!"

Jack did a double take. It was one thing for a flower to have a face, but being able to speak? "Hmmm… You're new to the UNDERGROUND, aren'tcha?"

Jack nodded. "Golly, you must be so confused. Someone ought to teach you how things work around here!"

Now Jack couldn't help but feel suspicious of that little smiling flower. But he nodded again anyways. "I guess little old me will have to do. Ready? Here we go!"

The room suddenly darkened. Flowey reappeared in front of Jack, but there was a dark blue heart floating in front of him. There were also stats in the corner of his vision. LV and HP. His LV was 1000. His HP was 9000. Flowey gained a look of surprise before quickly ditching the expression, settling for his usual friendly smile. Jack felt uneasy. "See that heart? That is your SOUL, the very culmination of your being!"

So his soul was dark blue? Jack was bewildered. "You idiot." Flowey's expression turned dark, it was just plain creepy.

"In this world, it's kill or BE killed. Why would ANYONE pass up an opportunity like this!? DIE."

Little white pellets appeared around Jack, forming a circle. Flowey's dark laughter echoed throughout the room as they got closer and closer. Before Jack could do anything, the pellets suddenly disappeared. Flowey's face was priceless. Then he got blasted by a fireball. Suddenly an anthropomorphic goat walked out of the shadows. It looked female, Jack decided. She resembled a white-furred Nubian goat, with droopy ears and short horns. She had a pair of fangs and long eyelashes. Her irises had a slight red tint. She was wearing a long blue robe with a strange symbol on her chest. "What a terrible creature, torturing such a poor, innocent youth…" She said.

"Ah, do not be afraid, my child."

"I am TORIEL, caretaker of the RUINS."

"Nice to meet you, uh, Toriel. My name's Jack. Jack Frost." Jack introduced, confusedly.

"Nice to meet you too, Jack. Anyways, I pass through this place every day to see if anyone has fallen down. You are the first human to come here in a long time."

"I'm sorry, but I'm not a human."

"Oh? Then what are you, Jack?"

"I'm the Spirit of Winter."

"Oh! You seem quite young to be the Spirit of Winter though, Jack." Toriel looked worried.

"Nah, I'm over 300 years old." Jack said, quite casually.

"Ah, alright. Come! I will guide you through the catacombs." Toriel didn't show it, but she was worried of Jack's LV.

The dark blue heart vanished and the room reappeared. "This way." She then turned around and walked away. Jack hurriedly followed her into the next area. They entered a long purple hallway. As they continued, Jack noticed a floating yellow…star? He walked over to it and pressed it.
