Xilian stood there, his miniscule size compared to Malicious Undyne looking laughable, however the pressure he was emitting was different from her. Xilian took a step forward, an invisible force shaking the bubble like consistency of the protective barrier, Malicious Undyne dashed towards Xilian grabbing ahold of him and ripping his skeleton-like arm off with her massive jaw. She then lobbed Xilians entire body across what was left of Waterfall.
His stats hadn't lied about him, he was indeed weak as his body began to dust away, he didn't put up much of a fight. Undyne's laughter echoed through Waterfall "I AM THE STRONGEST MONSTER AND NOTHING CAN STOP ME, NOT EVEN YOU! YOU WEAKLING!" She said, jumping to where Xilian landed as she stomped down on his legs, shattering them, she then continuously punched at his dusting body, his dust coating her armor and body.
Malicious Undyne walked, as the dust that once coated her began to rapidly retract back to where she pummeled whatever was left of Xilian, she hadn't noticed this as the dust particles were so small, however her heart began beating quickly, increasing in beats overtime. She felt her adrenaline suddenly spike as a cold sweat ran down her head. "The fuck? What's wrong with my body?" She then turned around to see a twister of dust began to slowly condense into itself.
A black smog was starting to fill in the area as purple thunder rippled through the air, the barrier couldn't take it as it began to weaken massively. Malicious Undyne's body couldn't stop shaking as she punched herself "FUCK THIS!" She said, lunging herself towards the twisting dust as her body got impacted with thousands of hyper-dense air bullets, her armor cracked violently to the molecular level as she got blown back with such force she went flying not only through Snowdin, but into the Ruins as well.
Malicious Undyne's health was about a tenth of what she originally had, her defence stat crippled down to 20 and her attack halved due to the exhaustion. "Th-The fuck did I just awaken.." She said, gripping onto the rubble to push herself up, she then lifted her head to see a massive streak of destruction, all the snow that once covered everything was now gone and turned to steam, all the tree's that flourished in Snowdin were burnt to a crisp and the rocky walls which covered most of the environment was completely broken apart into a circular shape.
Malicious Undyne stood up, her legs weak as she squinted her eyes to see what was standing in the midst of all the destruction her body caused, it was Xilian, his size grown from 4'5 to 6'5 and his old cloth which covered his face was now being lifted up into the air slightly, a majority of his face still hidden, but his left eye now radiated a green color as purple flames surrounded him where he stood.

*Unleashed, to show a fraction of what he could do to those who disobey him.
As her eyes couldn't stay open for long, she sluggishly blinked with her halberd in hand. Tyrant Xilian was infront of her in that instant, bashing her skull with a vicious uppercut which caused a majority of her teeth to fly out and break against one another, she grunted out in pain as Tyrant Xilian had grabbed ahold of her arm only to rip it off of her slowly, her tendons and muscles ripping, filling her with agonizing pain. "NGAAAAAHHH!!!" She screamed out, headbutting Tyrant Xilian as he then tore his boney fingers into her eye-sockets, pulling her eyes straight out.
Her halberd fell to the floor, as he punched her head, cracking her skull and popping a large system of her veins which started to leak blood inside her skull and all around her head, the blood visibly seen dripping down from inside her eye sockets. Tyrant Xilian then grabbed ahold of her Halberd and proceeded to slash her torso, opening her up as he grabbed ahold of her intestine only to shove it down her throat so she choked on them. He then impaled her Halberd into her thigh, breaking her femur bone. Malicious Undyne's screaming had been completely muffled by the intestine.
Tyrant Xilian then turned his heel and walked towards the city of the underground, leaving Malicious Undyne to feel all this pain for eternity as he had binded her soul with chaos energy, preventing her from dying, giving her the same fate as Alphys.
