Powertale

Powertale is an AU in which all the monsters have a superpower replacing their magic. The backstory of this AU is much different than normal. The playthrough of this AU would be fairly similar to Undertale Story-wise.

Story
Long ago, two creatures ruled the Surface World: Humans and Monsters.

The two races ruled in peace, but eventually anger corrupted the humans.

''They wanted control over the Surface World. The monsters fought back with all their strength, using their weak weapons to fend off, but with nothing but weapons to defend themselves, and men with their DETERMINATION, the monsters were quickly defeated.''

''The humans sealed the Monsters away under the cold, hard earth. But little did they know, the magic spell they had used to seal the monsters had given the monsters something. Abilities. Not magic, but what the humans would describe as "powers".''

And so our story begins, as a human falls through the mountain and finds themselves in the strange place called...

The Underground
The Underground looks fairly similar to that of Undertale's, with a few differences. Nothing that would be considered "magic" is there, being replaced with normal things (e.g the mysterious Castle in the background of the Waterfall passage is not there.), and certain other things are changed as well. A few of these differences are:
 * Grillby's jukebox is fixed.
 * The Library sign in Snowdin is spelled correctly.
 * Alphys's lab exterior is more beaten, part of the white paint being scratched off in a few spots.

Character Differences
Frisk: Frisk has a black eye and a bandage around their forehead. Their shirt is slightly ripped.

Napstablook: Napstablook appears more sad than usual.

Sans: Sans enjoys mayonnaise more than ketchup in this shocking turn of events.

Papyrus: Papyrus is actually a decent cook.

Nice Cream Guy: The Nice Cream guy will have small icicles hanging from his ears.

Burgerpants: Burgerpants smokes weed instead of normal cigarettes.

Powers
These are the various types of powers that each monster has.

Main Character Powers
Flowey: Flowey's ability is Meta. He knows he is in a game, roleplay, etc.

Toriel: Toriel can heal others and herself, however it is significantly more effective on others.

Napstablook: Napstablook's ability is immortality. He is completely invincible.

Sans: Sans's ability is one of the more badass powers... Arc of Space. Arc of Space is essentially an upgraded version of teleportation. It allows the user to teleport anyone and anything they wish to anywhere including other dimensions/universes, allows them to remember if time goes backwards, and even gives them the power to harness inter-dimensional energy. However, this much power saps up his energy, so his stats are halved.

Papyrus: Papyrus has the ability of flight, allowing him to fly anywhere he pleases, including places previously unreachable.

Monster Kid: Monster Kid's ability is all-powerful arms. Quite unfortunate, really.

Undyne: Undyne's ability is Superstrength. Honestly, what else would it be? I don't think an explanation is really needed for this one.

Alphys: Alphys's power is Super Intellect for obvious reasons. Super Intellect gives the user extreme intelligence.

Mettaton: Mettaton's ability is robot manipulation. This means he can control any robots.

Muffet: Muffet has the ability "spider queen". This gives her the ability to control arachnids.

Asgore: Asgore's ability is Pyrokinesis, the ability to create and manipulate fire.

Other Enemy Powers
Dummy: The Dummy has the ability to stay still at all times. Very useful thing, this power is.

Froggit: Froggits have the ability Superjump, an ability allowing the user to jump to extreme heights.

Whimsun: Whimsuns have the ability of a... unique form of Hydrokinesis which allows them to manipulate their tears.

Loox: Loox have the ability of laser eyes, allowing them to shoot a large laser from their eyes.

Vegetoid: Vegetoids have the ability to manipulate vegetables. Not a very good ability, but an ability nonetheless.

Migosp: Migosps have the ability of camouflage. They can make their skin blend in with their environment.

Moldsmal: Moldsmals have the ability to shapeshift, allowing them to change forms whenever necessary.

Snowdrake: Snowdrake has the ability to create and control snow, as well as manipulate(but not create) storms.

Ice Cap: Ice Caps have the ability to create(but not manipulate) ice.

Lesser Dog: Lesser Dog has the ability to manipulate defensive equipment, which can be quite powerful if used correctly.

Chilldrake: Chilldrake has the ability to create and control snow, as well as create and manipulate storms.

Gyftrot: Gyftrot is able to manipulate pine trees specifically.

Doggo: Doggo has the ability to control knives.

Dogamy: Dogamy has the ability to manipulate axes.

Dogaressa: Dogaressa has the ability to manipulate axes.

Greater Dog: Greater Dog has the ability to manipulate metal.

Glyde: Glyde can manipulate someone's personal image. He admits it's a terrible power, but it's perfect for lowering someone's dignity.

Jerry: Jerry has the ability to manipulate moods, however he only negatively effects their moods because he's a jerk.

Aaron: Aarons are bulletproof. They have skin tough enough to block even bullets(but not Undyne's punches).

Woshua: Woshuas have Hydrokinesis, the ability to manipulate water.

Moldbygg: Moldbygg, like its smaller counterpart, has the ability to shapeshift.

Temmie: Temmies have the ability to stretch their limbs as far as they want.

Vulkin: Vulkins have the ability to create and manipulate lava.

So Sorry: So Sorry has the ability to bring drawings to life.

Royal Guard 01: Royal Guard 01 has the ability to manipulate armor.

Royal Guard 02: Royal Guard 02 has the ability to manipulate blades.
