Tyrant Xilian enters the Undertale Universe

With Mettaton getting his reconstruction, it was now the flower's turn. The antagonist of the game and a prince whose fate was brought down upon saving a best friend.

Flowey looked around, incapable of moving as he was in what looked to be a flower pot, however, as he admired the hallway his body was slowly restoring itself, his body slowly returning back to what it used to be. Flowey looked shook, looking at his body suddenly transforming into his goat form. "H-Huh?! But I don't have any souls, how is this possible?!" He exclaimed, letting out a deep sigh. "Man, this place is cold, the least they could've done is let some warm air inside.." Flowey, also known as Asriel felt his empty soul become warmer, his body glowing a light yellow color.

"Oh..This-" He felt lost for words, stopping in place and reminiscing of his childhood. "It's the same feeling of.." He shook his head "The past, is the past.. I shouldn't get caught up in it.." Asriel said, rubbing his left cheek as a little tear droplet was forming, his lip trembled for a moment as he then heard a voice in the distance. "Come, Asriel, let us talk." The voice was soothing to the heart and to the soul. Asriel shyly wandered down the hallway and got closer to the throne.

"Who are you? And, how.." Nailix answered. "The impossible is possible here and your miracles happen here." Asriel's heart beat for a moment, hoping that they could see them one last time. "T-Then that means- A-Are they?!" With grief, Nailix responded. "No, your family and your sister are not here. The reason is to give them peace and to let them exist elsewhere, somewhere where they can be full of joy." Asriel wanted answers, he yelled out with tears running down their face. "IT WAS ALL THEIR FAULT! THEY DID THIS, THOSE DISGUSTING HUMANS! I JUST WANT MY FAMILY BACK, MY OLD LIFE BACK!" 

Nailix was standing behind Asriel as he knelt down to put their hand on their shoulder. Nailix had tears rolling down his face. Though Asriel couldn't see his face, he could feel the tears even though they didn't exist in the 3rd dimension. "I feel your pain, you will be loved here and taken care of. You are our little goat and we will make sure you will feel the utmost joy." Asriel asked, their voice quieter. "Could I.. Hug you..?" Nailix then hugged Asriel against himself, patting their back and remaining silent so Asriel can relieve themselves of their sorrow and guilt.

"Asriel, we must do what you came here for." Nailix said, looking down onto Asriel. Asriel then looked back up at him "Wh-What is my purpose..?" Nailix appeared behind Asriel as he walked up the stairs to the throne. "You show the most potential out of your friends, the most capabilities to handle power. You are known in the multiverse to be one of the strongest candidates for power in just your timeline." Asriel wasn't following, he was already confused. "Timelines..Potential..?" 

Nailix sat down, pointing up as a spectral monitor formed. This monitor was showing Asriel the Pacifist route, how he obtained all the monster souls as well as the six human souls, turning into a Deity of the underground. Nailix spoke "Not only did you have the power of a low class deity, but you also had low levels of reality warping. Safe to say, your body could easily handle such power without any drain, not only that, your own power fueled the souls themselves, allowing them to be powered indefinitely."

Asriel looked in awe, pointing at Frisk. "Who is that?" Nailix answered "That's Frisk, the human who committed the genocide route in your timeline, they're the polar opposite in that timeline and eventually become your friend, freeing everybody in the underground." Asriel thought for a moment, wiping the stains of his tears. "Where do we start..?"

Nailix smiled, flicking his fingers as all the remaining 6 human souls appeared here. "You will all be working together and will unify into one being. You will be able to separate at will, but only if everybody else agrees. Not only that, but you will all be a family that will look out for each other." Nailix then stood up as he waved his hand, all the six human souls regained their physical forms as their clothes matched the color of their soul colors.

Asriel looked at them, stretching out his hand. "H-Hello, my name's Asriel." The souls all spoke, greeting Asriel. "Hello!" Nailix then walked down the stairs. "My final gift to you is a wish that you want granted, however, you cannot revive the dead." They all pondered as the souls wished for simple things like their favourite toys, comic books, cooking utensils and some delightful food that they can enjoy in peace.

Asriel, stumped on what to wish for, just sat down and thought deeply. Grumbling in annoyance, they rubbed their head "Man, I know others will scream at me for not wishing for something better but..Please, can I have my mom's butterscotch cinnamon pie..O-One that doesn't spoil and regardless of how many pieces you take away, it comes back."

Hearing this request, Nailix flicked his fingers, giving Asriel what he wished for. "Now that you all got what you wished for and more, it's time to initiate the 2nd phase of the plan." Nailix summoned sixteen copies of himself around them, he clasped his hand together as all the souls and asriel began radiating a white glow.

Asriel let out a loud scream as all the six souls turned into pure light. Their color represented their soul color as they all then merged into Asriel. A gargantuan beam of light consumed the hall which then beckoned out. The light was so intense that its light was visible from Heaven, a dimensional layer completely outside of the Hall of judgement. The angels looked in awe, feeling this power being unleashed. Each primary emotion coursed through the angels as the light had then vanished.

Asriel Dreemur now stood, successfully merged with the souls, he had 4 horns and adorned his outfit that he had from the pacifist route, however, each soul was implanted on the robe, he also wore sandals and had a ring behind him, this ring had the six souls implanted in it as they then split, turning into 6 smaller rings which then covered his head. Four miniature wings then formed which covered his face and six larger wings behind him, the wings then coated his arms and legs, turning the robe more mystique. The black deltarune sigil's black outlines turned golden as feathers bracers formed all over his forearms and legs.
