Xilian watched as his beastly Creation got destroyed, his mind filled with pure anger, his boney hands clenched together. Looking at Asgore mourning the death of the Amalgamates, he turned his heel and walked towards waterfall. Noticing a lack of monsters within waterfall, he was free to walk without a disguise, though the River Person stood in front of him.
"Your meddling with the timeline will delay the inevitable of greater threats to seek and destroy you, you are now but an anomaly in the vast multiverse. A disease which will get wiped out and forgotten, a plague which will get cleansed." Xilian attempted to go for the River Persons head, however, he wasn't able to touch them. Phasing through their incorporeal body he dug his foot down into the tough stone to stop himself, looking back at them, they spoke. "I am here, I am everywhere and I know all of what you have done." With that last message, they ceased to be, vanishing as fast as they came.
Xilian felt frustrated and annoyed, turning to walk towards the bout that was about to happen. He pointed his finger upwards as a bone like platform dug from the stalactite, he sat down and looked at Undyne and the Human, he checked the humans data once more, seeing that they had an LV of 11.
Undyne stopped them, brandishing her weapon and pointing her spear at the human, with an angered expression they launched themselves forward. "NGAHHH!" Undyne released an unrelenting flurry of attacks, shooting spears from all around the human.
The human, with their reddish glaring eyes dodged the attacks effortlessly, showing little to no struggle against Undyne's attacks and with a single attack they punched Undyne's armored torso. Undyne let out a loud gasp as she got blown back with the attack, her armor denting deep into her torso, her ribs broken completely as they punctured her organs badly. The human approached Undyne slowly, each step echoing as their silhouette was the only thing she saw within the smoke.
The human's red eye's faintly glowed only adding onto the eeriness. Undyne stabbed her spear into the ground, gritting her teeth as she was filled with an undying determination to stop the human. " No... s-somehow, with just one hit... I'm already... Already... D... damn it...." She put her hand on the damaged armor, her head looking down at the floor, her saliva coating the bottom part of her face. " My body... It feels like it's splitting apart. Like any instant... I'll scatter into a million pieces. But... Deep, deep in my soul. There's a burning feeling I can't describe. A burning feeling that WON'T let me die!"
Undyne finished her monologue much sooner than usual, becoming another anomalous event, Undyne's body was breaking apart, her soul coming to view as it became red, Xilian looked at the soul of determination. With a light hand gesture, he formed out a small purple particle. Xilian proceeded to flick the particle down at Undyne's determined soul and as it landed on it the two absorbed into one another. Frisk's eyes widened in surprise, feeling the sudden change in pressure as the middle of Undyne's soul formed a purple flame.
Undyne's body began to take shape, her armor forming rapidly as her undying armor now had a change in appearance, looking much more sharp and menacing. The heart in the middle of the armor now also sporting a purple flame. "NGAAAAAHHH!" She yelled out, an intense warcry shaking the underground once more, the mountain grew more and more unstable. Xilian noticed that one of their attacks could destroy the whole mountain top with ease, however the barrier was keeping the whole place together for they needed planetary power in order to shatter such a barrier and to break the protective spell.
The sound of Undyne's laughter echoed, her covered eye leaking a crimson blood which evaporated into red smog before reaching the floor, she bared her teeth, full of malice intent holding an energy glaive instead of a spear. Her armor became bulkier but also more dangerous; it had sharp edges all around it.
Malicious Undyne The Undying:
HP 166000
ATK 800
DEF 650
*The determined Heroine, full of malice, ready to take care of the Human.
The Human called Frisk stared in terror and their little ghostly apparition named Chara as well, they were not expecting such intensity, such power, to radiate off one being.
