Mettaton looks around, but doesn't see anyone. "Mettaton," Frisk explains, "it's me, Frisk. Chara is coming. Can you beat them?"

"Oh," Mettaton smiles, "don't worry about that. The upgrades to the human eradication program are complete. As soon as Chara comes to The Core, they're dead.

Chara struggles through The Core. The monsters are immensely powerful, but Chara manages to reach the exit, but Mettaton blocks the way.

"This doesn't have to get messy," Mettaton explains, "just give Frisk your soul."

"Never," Chara replies, "I can't go back to being that... thing. A soulless husk, no compassion, no hope... I'll never go back."

"Fine," Mettaton smirks, "then it's time for the series premier and finale of 'Revenge of Neo!'

Mettaton starts a FIGHT.

"Let's get to the point darling," Mettaton changes into Mettaton Neo, "I'm not letting you use MERCY, and if you FIGHT, you fail, so what are you going to do? Kill me, or die? Here, I'll give you the first hit."

Mettaton waits for Chara to make the first strike. Chara clutches the knife. They try to offer MERCY. Mettaton doesn't bat an eye. They check their ACT menu. They can plead, roast, and fake attack.

Chara decides to fake an attack.

Mettaton stops after the hit, taking only one damage.

"Heh," he chuckles, "you really are just like Frisk aren't you? Listen kid, for what it's worth, this is nothing personal, but Frisk doesn't deserve to be stuck as a soulless husk. For what it's worth, I'm sorry."

Mettaton attacks. Chara douges narrowly, knowing his Neo form has massive atk, and will likely kill Chara in a single strike. Chara pleads.

"Don't make this harder than it is," Mettaton sighs. Chara can see that they're getting through to Mettaton.

Frisk gets agitated. "They're manipulating you," Frisk reminds, "stop holding back!"

Mettaton sighs, "you're right. I'll end this."

Mettaton prepares a massive attack. Chara pleads one last time, "Mettaton, I know I've done horrible things, but please, if not for me, for Asgore and Toriel, let me pass. I'm going to break the barrier, I'm going to free everyone. Please, we don't have to FIGHT."

Mettaton thinks about Asgore and Toriel. How happy they would be to have Chara back. Mettaton hesitates. He considers offering MERCY.

"Mettaton they're manipulating you," Frisk tries to talk Mettaton out of it, "just kill them. It won't be hard. Just one quick strike and everything's fixed. I ask you, as a friend, kill Chara, and get me my soul back."

Mettaton decides to keep FIGHTing. Chara douges again. Undyne calls on Mettaton's phone.

"Mettaton," she sighs, "let Chara pass."

"What!?!" Mettaton exclaims, "this was your plan!"

"Yeah but..." Undyne sighs, "do it for Asgore. It's... better this way."

Mettaton listens to Undyne and offers MERCY. Chara immediately accepts.

"For the best anyways," Mettaton smiles, "I'm running our of batteries anyways. Hey, kid, stay good. Be 'The Hope of the Underground'." Mettaton runs out of batteries. Frisk knows there's only one person left They can turn to, Sans. Frisk contacts Sans.

"They're coming," Frisk warns.

"I know," Sans replies, "good to see you kid."

"Are you ready Sans? They're skilled, and will know your attacks."

Sans grips his stolen DETERMINATION. He hasn't used it yet, but soon...

"Yeah," Sans smiles, "I'm ready."

Chara begins towards the Judgment Hall. Flowey stops them in a FIGHT. "So," he grins, "you're really gonna make it, huh?"

Flowey ends the FIGHT. Chara finds a key. They go to find the other. Another FIGHT starts.

"Do you really think you can atone?" Flowey asks, "you, Sans, or Grilby? Can you ever move on? Can you ever forgive yourself?" The FIGHT ends.

Chara feels the weight of their sins returning. They struggle to continue. Another FIGHT starts.

"Chara," Flowey explains, "I don't know what happened last run, after all, I died, but now that you're back, we can destroy humanity together."

The FIGHT ends. Chara finds a heart shaped locket. They check it.

Chara's Locket. 99 def. A gift from your best friend. Fills you with DETERMINATION.

Chara puts the locket on. They continue after finding the second key. Yet another FIGHT starts.

"It won't be hard," Flowey grins, "after all kids like you, should be burning in Hell! So let's make the most of it eh? Let's destroy humanity together, like we originally planned."

"Listen," Chara growls, "I don't know what you are, but you are not Asreil Dreemur. Get out of my way."

"Fine," Flowey snaps back, "good luck with Sans, and if you need help, remember," Flowey gets an eerie expression, "your best friend's always here." Flowey disappears.

Chara continues to the Judgement Hall. Sans blocks the way...
