Going back to Xilian..
Xilian looked around, his body leaking Concentrated dark matter from forcibly ripping through wherever he came from. He saw piles of dust everywhere and the last thing he saw was what looked to be Frisk, this frisk was just going through the genocide route. They looked to be LV 17 as they steadily approached Xilian, holding their knife in their hands tightly.
Outertale Frisk (LV 17, genocide.)
HP: 84
ATK: 42
DEF: 14
*A filthy genocider
Chara's soul lingered around Frisk, smirking and speaking to them "It's just another monster, let's see how much XP it'll give us.~" Frisk lunged towards Xilian, slashing their knife consecutively, each slash launching a devastating air slash which obliterated any material that came in contact with it. Xilian moved his body so precisely each cut was only millimeters away from impact, Frisk was starting to get frustrated as jumped back, cutting the knife into the ground to stop themselves.
Frisk panted whilst gritting their teeth as their knife glew a bright blood red. This amplified their physical capabilities in allowing them to move at Hypersonic speeds. They launched off the ground and cut the air once, their arm, visibly vibrating momentarily as hundreds of the same blood red air cuts formed next to one another filling the sky. Xilian looked up, unphased. Frisk swung downwards, each slash booming forward so fast that each one broke their own sound barrier. Under Xilian's cloth, a visible green light started radiating.
Each slash impacted the ground, leaving behind a deep cut down the gargantuan sky island. Vapor radiated off of Xilian as he just stood there, his clothes cut from the slashes which did hit him. Frisk's eyes opened wide, they could feel a sense of dread as Chara then spoke to them. "Quick, we need to use it!" Frisk spoke, confused. "Use what?!" It then clicked on them "Oh, you mean that strange fragment that was given to us?" Chara smirked in her ghostly form, nodding.
Frisk then landed roughly, dispersing dust all around as they took out a radiating black and crimson fragment. They then absorbed it as a violent whirlwind of energy erupted out of them. Xilian felt this before as he then got reminded of his previous battles, though it wasn't that long ago, it was the same energy he felt when he faced the determined freak of the timeline he was ordered to take over.
Xilian spoke, shaking Frisk's soul. "Who gave it to you?" Frisk gloated as the Chara beside them also started manifesting into their Physical form, the both smirked and responded. "Well, since you want to know so badly, another 'ME' gave it. But since you are about to die, I won't go too deep into the details." The two got ready, showing pure confidence.

The air around Xilian twisted and bent as the light from his pupils started rapidly moving towards them. Xilian's body showed afterimages of moving closer as he had opened up his palms, grabbing ahold of both of their faces he threw them across the field which made them violently impact into an asteroid.
The two, surprised that they couldn't follow him, decided to check on his stats. The toolbar appeared in front of them as it read..
Xilian (Heavily Suppressed+)
HP: 1
ATK: 1
DEF: 1
*The easiest enemy
They both were flabbergasted, complaining. "What is this bullshit? Easiest enemy my ass!" Xilian formed right in front of them grabbing a hold of the stat toolbar and twisting it. Frisk's eyes widened as she shook "H-He can do that!?" Chara then just smirked "Dont worry partner, he can only deal 1 damage! Compared to our large health pool he is nothing!"
Xilian spin kicked both of their heads, which sent both flying to their respective directions, that being left and right. Xilian stopped mid-air next to the asteroid as he grabbed ahold of it. "I will feed into your foolish and pathetic curiosity."
The two lifted themselves off the ground, looking up at him in anticipation, their soul started reacting on its own, wishing to flee. They both held their torso, gritting their teeth in pain. Frisk coughed out blood, struggling to talk. "I-It's like my body wants to depart from me.. N-No it's like my whole being wants to run.." Chara's body began to back up as the both of them then started to run away.
Tyrant Xilian (Suppressed)
HP: 20.5 Billion
ATK: 13.5 Billion
DEF: 7.5 Billion
*Impending dread radiates off of him like a neverending fountain
Xilian formed in front of both of them, occupying both spots at the same time, he grappled their face and slammed them against the hard rocky floor, he grabbed ahold of Chara's leg, only to twist it to unrecognisable levels, the bone itself not even being straight anymore as it was bent in an impossible way. Chara screamed in agonizing pain as he grabbed ahold of her jaw, twisting it and pulling out her bottom row of teeth. Chara's vision became blurry as her ears started to ring. She attempted to swing her knife only for Xilian to grab her hand and puncture the frontal lobe of her skull with it. He then grabbed ahold of his mouth region, ripping it open. Shards of bone sparkled down Chara's mangled body as a black smog startled seeping out of the now open mouth region.
Chara coughed out blood, speaking. "Wh-Ghrkk...A-Are you doing.." As the smog went into Chara's lungs, her soul became bound to the chaos energy she absorbed, she could feel her vision coming back. "Giving you a fate worse than death, for you insects don't deserve the sweet release of death." Xilian said, his ripped open skull shaping into a demented grin. Chara screamed out for help, but nobody came. Xilian stuck his hand down her jugular, pulling out her larynx and crushing it in his hand. Chara's eyes became bloodshot as she could feel every inch of pain.
Frisk summoned the reset button, using it in desperation. She got brought to the menu screen as it then started melting away. "Your reality and fate has already been set." Said Xilian, walking through the melted screen as Frisk let out a gut wrenching scream of fear, only for her to meet the same and possibly more gruesome fate than Chara.
