PotterTale CH 1

Summary: While on the Horcrux hunt, Harry's luck takes a turn when instead of going to Gringotts with Ron and Hermione, he is taken to Mt. Ebbot and meets a strange child in a striped shirt and together they fall down. How will Harry and Frisk make their way through the Underground?

A/N: Oh yeah, another story. I know, I hate myself too, I already have three other stories that I barely update, but Undertale has had such a marvelous impact on me, just like the Harry Potter series, and I have yet to find a crossover quite like this one, so I decided to write it. Sue me.

Taking a gulp, Harry looks at the polyjuiced Hermione and transfigured Ron and throws his cloak over his shoulders, Griphook making like his name and gripping onto Harry's neck with a firmness he thought unnecessary. Letting out a breath, the black-haired boy spun in place to Apparate to Diagon Alley.

Only, of course, something went wrong.

Only natural, isn't it? I mean, we're talking about Harry Bloody Potter here. He's Fate's freaking punching bag.

Griphooks hands slipped away from his neck as they were squeezed through a tight rubber tube, and Harry appears on top of a mountain, next to a genderless child in a purple and pink striped shirt with a medium-brown bob that covered their squinty eyes and cargo shorts.

All in all, the child was adorable.

"Erm, hullo." Harry greeted uncertainly to the unfazed child, who looked around the area, as if looking for-

Oh, right.

Harry was still wearing the Invisibility cloak.

Ducking a good couple of feet behind the child, the young man takes it off and shoves it into one of his jackets magically enlarged inner pockets. Clearing his throat, Harry waited for the child to turn around before crouching down onto his knees. "My name's Harry, what's yours?"

The child seemed to assess him before opening their mouth. "Frisk."

"It's nice to meet you, Frisk. Why are you up here all alone?"

"I'm not alone."

"What?"

"You're here, mister."

Laughing a bit, Harry stands back up. "I suppose so, kiddo."

The clouds that had been gathering in the sky without the two noticing decided they wanted some attention, and threw a tantrum. Both occupants of the small clearing looked up at the flash of lightening and the crash of thunder as it started to rain buckets. Spotting a cave a little ways away, Harry points to it. "How about you and me wait out the storm in there? I'd hate for either of us to get sick."

Frisk nods and silently takes Harry's hand in their smaller, softer one. Smiling, Harry quickly heads to the cave. Upon entering, Frisk lets go of his hand and wanders further into the cave, and the teen looks out at the storm in worry.

'I hope Hermione and Ron are okay,' he frets, biting his thumbnail. 'Griphook, too. How did I end up here? And how do I get back? I suppose I should help Frisk, though. I don't want he-she- them to get hurt.'

As though listening, the small child (though really not all that small, probably about ten or so) calls out his name in a bit of a panic.

"Harry?"

"Yeah?"

"Could you come help me?"

"Yeah, sure, what do you need- Oh, dear Merlin."

Frisk was holding onto a ledge about fifteen feet down from the edge of a chasm, their sneakered feet brushing a dark abyss.

"Hold on, let me find something t throw down to you or something." Harry was internally freaking out, but kept a calm façade as he found a thick vine. It wasn't long enough to reach Frisk, not without them jumping for it and Harry didn't want them to die. Quickly dropping it down and wrapping some of it around his arm and taking a firm grasp of it, Harry scales down the side of the chasm and hold his free hand out to Frisk. "Quickly, take my hand!"

Frisk reaches out and grabs onto him, hands shaking; it seems they weren't as calm as they had portrayed. Using all of his strength, the black haired young man hauled them up onto his back, the child's arms wrapping around his neck and legs wrapping around his waist. Panting and groaning with the effort ('Oh, if only I had my wand!' the wizard moaned), Harry began to climb back up the chasm, and was nearly at the top when the vine snapped, causing the two humans to fall down.

Frisk screamed.

Harry did the only thing he could think of. He brought Frisk around to his chest and waved his hand below them, yelling "Arresto Momentum!"

When the two humans awoke, they were on a soft patch of golden-yellow flowers, with nary a scratch between the two of them.

"Harry, what did you do?"

Deeming Frisk young enough to still believe in Magic, he said "Magic, of course!" (Note: He was smiling nervously, a bead of sweat slowly making its way down his back.)

Nodding, Frisk stood up and Harry let out a sigh of relief before standing as well and taking the kid's hand. Seeing a tunnel, both humans began to walk towards it, coming upon a door. Entering it, they see another of the golden flowers.

But this one had a face.

"Howdy!" it says, reminding Harry slightly of Mickey Mouse.

"I'm Flowey! Flowey the Flower!"

Harry feels a sense of dread swoop down upon him.
