Frisk clenched their fists, but let them fall to their sides with a sigh. They sat down and lean against a pillar. Frisk breathed in and out slowly.
A familiar voice entered their mind. "There isn't time to waste, Frisk. Finish what you began. We're on the brink of success here!"
"Y- You saw what happened, Chara. Four times. That thing killed me four times in a row and I haven't even seen their face yet. I haven't gotten to attack or formally enter battle. I- I don't know if I can do it," Frisk muttered.
Frisk thought they heard something vaguely like snickering. Then, it was as if they weren't trying to hide it anymore. "Haha! Like I haven't heard that one before! Though I must say, you really 'jumped the gun' this time."
"After killing Flowey, I should've been strong enough to destroy the entire timeline with a simple strike, but…"
Chara sighed. "I think that's because you haven't emptied the underground yet. There's still someone here who wants to fight. One person who hasn't curled up and succumbed to defeat. Yet."
Frisk clenched their teeth and pleaded their case. "Still… he killed me in a single strike. With a single shot, my HP dropped to zero. It's not like Sans. It wasn't a single attack, it was a single strike. With the locket and maximum level, he shouldn't be doing nearly so much damage!"
There was a moment of silence. Then, it sounded as if Chara was breathing in and out slowly. It was purely for dramatics though, as the dead didn't need to breathe.
"Your guard was down. It's just like what you've done in previous runs; when you convinced someone not to fight you until they agreed, then betrayed them and killed them at the last moment in a single strike. They didn't have their guard up and you bypassed all their defenses. Now that's happening to you."
"Oh…" Frisk felt like an idiot.
Chara got the conversation back on track. "You were shocked and scared after Undyne showed you her true strength too. Once Sans showed how hard he could fight, you went through the same thing. You killed them both. What's this guy compared to them?"
Frisk sighed and stood up. "I guess you're right. I'm ready to try again."
Frisk brushed the dust off their pants. They faintly heard footsteps approaching and turned up to see Asgore standing on the other side of the corridor, far away from Frisk. There was a song accompanying him.
*3 Left
Frisk took out their knife and stepped forward.
Asgore sighed. "I'd hoped to talk to you, maybe offer you some tea, but something tells me that wouldn't end well, so… know that you leaving the underground was never a possibility. Your fate was sealed as soon as you entered my kingdom."
*Getting serious
Asgore revealed his trident and threw it at Frisk. Frisk sidestepped and barreled forward at a sprint. Asgore released fire in waves, filling the corridor. Frisk dodged and weaved through the fire, closing in on Asgore. As Frisk gets close, Asgore revealed another trident as his eyes flashed red a few times one after another. Then, he swung his trident towards Frisk at lightning speed. Frisk stepped back to avoid the swings. Then, Frisk lept forward towards Asgore, swinging their knife. Asgore swung his trident and the two weapons clash repeatedly as Asgore backed up into a pillar.
*Cornered
Frisk steps back for another swing and Asgore holds out his trident to block. His trident is cut in half and dissolves into magic. Frisk steps closer and plunges the real knife deep into Asgore. The number "99999999999" hangs above him. Asgore gasps as he dissolves into dust, leaving behind his soul. Frisk grabs his soul with their hand and shatters it.
Frisk reaches for their knife, noticing it's stuck in the pillar. With a bit of effort, they retch it out. Then, Frisk trudges back to the beginning of the corridor again and interacts with the save point.
*2 Left
Frisk saved. Then, Frisk walked back across the last corridor towards the throne room. They notice that just outside of the door is another save point. That would save them a bit of time for each of their eventual resets, so they interacted with this one too.
*2 Left
Frisk took another step, trudging into the throne room…
