Chara had just finished their monologue, at the end of the Genocide Route.

"So. Which one? Erase, or Do Not." Chara said to Frisk.

Frisk was about to say something, when suddenly Chara got this strange look on their face.

"Hmm? It seems there is still someone willing to fight us. Let us go see who it could possibly be." Chara said.

The dark room suddenly changed to the True Lab as they were teleported to it.

They had appeared in the DE Extractor room.

'Why are we here?' Frisk thought, frustrated.

Suddenly they heard a coughing.

They looked to where the coughing was, and saw a child, staring at them.

"Why did you do this? Why did you kill everyone I cared about?" The child said.

This opponent was wearing a blue sweatshirt around his waist, and a red scarf around his neck.

"Why? I can't believe I once called you friend." He continued, both eyes closed.

"Just for the fun of it." Chara said shrugging, and slashing at him.

He dodged, much to their surprise.

"You don't remember me. But I remember Y O U!" The mysterious child said, looking down.

Chara attacked again, this time hitting him, as he had made no attempt to get out of the way.

(-99999 HP) Read the damage counter. His health bar dropped to zero.

He dropped to his knees.

Black tears fell from his empty eyes.

His soul appeared, cracking, and splintering.

Slowly, to their surprise, he got up, his HP returning to full. The cracks in his soul disappearing.

"But it refused. I refuse to die, while your still alive. I must avenge my friends." He snarled, rage appearing in his black, empty eyes.

"Toriel, Papyrus, Undyne, Mettaton, Alphys, Sans, Asgore, and even Flowey. All of them dead. Because. Of. You!" He continued.

"This is what your fifteenth Geno. Run? I'll make sure it's your last." A red pinprick appearing in his left eye as he said this.

"Deep inside my soul I can feel all my friends, calling for your death. I'm happy to oblige!" A blue pinprick appearing in his right eye, as he said this.

White flames trailed from his eyes, and black tears rolled down his face.

Alphys takes Action Piano version started to play.

"For all my friends, and every innocent soul YOU shattered. I will defeat you." He growled, Gaster Blaster's, Spears, Flames, Bones, and Bombs appearing behind him.

"Wh-Who are you? I've never seen you before!" Chara asked, an uneasy look on their face.

"I didn't expect you to remember me. But I'll give you a hint. It's me. Your old friend." He paused.

"Walter Dreemurr. The child lost to the void. And the bringer of justice." He said this as the Six Human Souls appeared around him.

The room went black, as they entered the battle.

"Heh... You know it's funny. When I was alive, I never wanted to fight with my family. Ironically, you're the person I wish most to fight." He said grinning crazily.

"Ha... HA HA HA! What is this feeling!? I know this. This. Is HATRED! Hatred for you. Hatred for all you've done, and Hatred for all you intend to do." He yelled crazily.

"You made a mistake coming here Walter. I'll slash you to pieces!" Chara screamed, launching forward.

DM DOKURO's Reality Check Through the Skull started to play.

Chara felt a stabbing pain through their chest, and looked down.

There was a hand sticking through it.

They looked up at Walter. It was his hand.

He ripped his hand from them, gripping they're soul.

He slowly closed his fist on their soul, cracking it, and finally shattering it.

The las thing Chara heard before it faded to black was " L!"

They reappeared at their save point, staring shocked at Walter, as they entered battle once more.

"Ready for round two?" Walter asked shrugging.
