Every Single Undertale AU of Mine

1. Startale:
 Frisk, a human was transported to the 24th century where human life and most monster/alien and human life are living in peace, and they have accumulated space travel.
Frisk joins this Starfleet as they call it. And graduated and went from cadet to Ensign. They were lucky, as they were placed on board the USS ENTERPRISE. They sometimes encounter trouble as they "Search for new life and new civilizations, and to boldly go where no one has gone before"

2. Elementale:
The monsters of undertale were transported to the future; where humans were very rare. They then found a stone incased in magic.
A certain monster was drawn to touch it, [Gaster] and he touched the stone. It took his memory and replaced his memories with different scenarios and removed all knowledge of him and the others transporting to the future. The stone also gave them the capability to control certain elements.
Gaster can control the shadow element. He can incase himself in shadow, which makes him stay invisible. He can also trick the mind into doing his bidding. He did that to let all of the other monsters use the stone; which gave them each different powers.
But now, their lives are connected to the stone.
Destroy the stone, kill the monsters.
A human named Chara stumbled into a small village the monsters made. The monsters attacked Chara in fear; even though they were peaceful at the time.
Chara was killed.
The monsters realized what they had done and grieved, until another human ventured into their town. This human's name was Frisk. Frisk is also friendly, but is slowly becoming corrupt from the vengeful Chara.

3. Adventuretale
Adventuretale is a fun crossover of Adventure Time and Undertale!
All of the characters in Undertale are combined with each of the people from Adventure Time! Some are even Fused!
Asgore and Flowey: Ice King.
Frisk: Finn
Tem: Jake
Toriel: Bubblegum Princess
Nabstablook: Marceline
etc...

4. Othertale:
 A Land where all of the monsters have changed into the opposite monster corresponding to their species:
Frisk and other humans are Skeletons, Sans and Papyrus are the only humans (besides Gaster), Toriel, Asgore, and Asriel are sheeps, Undyne is a Kitty Cat, etc. Though their personalities are still the same.

5. Helltale:
 Toriel and Asgore were still together, Asgore was kind of rough on the people of the underground, and they rebelled, enslaving and killing Asgore and all of his followers. Toriel has to hide from the others, who ransacked, destroyed, and practically burned everything to the ground, and since there is no leader, and they have become an anarchist community.

6. Underscope:
Underscope;
Memes meet undertale.
In Underscope, the background is always white, unless they are high, in that case, it has demons and rainbows.
all of the monsters are made after the memes, and most take on a greenish/dank color.

7. Other Kingdoms:
As you know, Frisk and the other humans fell down into the underground, but in this Alternate Timeline, Frisk, and the others don't fall down into the Undertale Underground, they fall into a similar place that has similar people, similar towns, but something is different.....
There is no Toriel, no Asgore...no Asriel, Grillby, etc.
There are a set of new people, and as Frisk found out, it is one of the other kingdoms that are out there. The other known kingdoms are;
The Stronghold (Undertale)) Grigon Empire ((This one)) Shadow Crest, ((You will find out later in the story)) and The Sun's Peak. ((You will also find out later))
