Prologue 1

"I want his determination and with it... I can do the same thing my family did 1000 years ago."

- Prof. Vile

Prologue 1 is the first episode of the Skytale series.

Synopsis
Frisk and his friends have been freed from the Underground and all is well, but who is this mysterious character?

The Surface
The episode starts off with Frisk, Toriel, Sans, Papyrus, Undyne, Alphys, and Asgore watching the sunrise from the Surface. As everyone is enjoying the view, a mysterious man in a cloak is seen walking to the entrance of the Underground. Frisk is the only one who noticed the figure, but he decided to stay quiet and follow his friends down to the city.

The cloaked figure is known as Professor Vile, as shown in this episode. The scene transitions to him walking into the Underground, searching for the human souls. Once he finds them, he holds out a Neutral trait soul and drains the human souls' magic with it.

Professor Vile then goes to Flowey, who is acting depressed due to being alone. Flowey then wishes to have a happy ending just like Frisk and the others, to which Vile replies, "What if I told you that I can give you a 'happy ending'." He continues by stating that everyone deserves a happy ending, even a soulless flower, but then he asks for something in return. Professor Vile then referred to Flowey as 'Asriel,' indicating that he has some knowledge of Asgore and Toriel's son. 'Flowey' refuses Vile's offer, but then the Professor shows him the soul with the six traits; Bravery, Justice, Kindness, Patience, Integrity, and Perseverance. Vile then explains the offer again by saying, "I mean you can be a wise guy about it and stay as a talking plant... or you can live with your family. Your choice." Flowey hesitantly agrees and absorbs the soul. Flowey then turns back into Asriel, and he appears shocked when he reformed. He then thanks Prof. Vile and asks his name, to which he tells Asriel what he should address him by.

True Lab
Asriel takes Professor Vile to the True Lab, where he finds the DT Extractor and brings Gaster back from the void.

Gaster comes back and asks Asriel what he is doing here, and the goat replies to him by saying that his new friend Vile brought him back. The Royal Scientist shouted at Asriel and warned him that Vile is a dangerous man. Professor Vile then attacks them with an Anger trait attack, but Gaster shields them just in time and escapes with Asriel.

Lastly, Vile addresses that he needs Determination in order to do the same thing that his ancestors did 1000 years ago.
