Frisk slashes over and over, causing Flowey to get smaller and smaller with each strike. Frisk watched as the Flower's body disappeared from existence, leaving a few bits of stem.
Then, there was darkness. The hatred from Frisk grew strong, their Determination brought something back..
After a few seconds of blackness, a figure, someone who looked like Frisk, but with bigger eyes, appeared, wearing a green shirt with yellow stripes. The child was... smiling. Again, Frisk was... surprised. The only other time they was so surprised was when Sans did his first attack.
"Greetings. I am Chara. Thank you" The child, known as Chara told Frisk. Frisk was confused by Chara's words.
"Thank you? For what?" Frisk asked. Although many believed Frisk was mute, they just were shy, and didn't want to talk as much.
"Your power has awakened me from death. My 'Human soul', my 'determination'... They were not mine, but YOURS."
"W-what? How?" Frisk frantically asked. Chara giggled.
"At First, I was confused as well. Our plan had failed, hadn't it? Why was I brought back to life?" The child said nothing for a few seconds. Then it's eyes perked up, staring into Frisk.
"You. With your guidance, I realized the purpose of my reincarnation. Power. Together, we eradicated the enemy and became strong. HP. ATK. DEF. GOLD. EXP. LV. Every time a number increases, that feeling... that's me. 'Chara'." Frisk tried backing away, but was stopped by... darkness...
"Now. Now we have reached the absolute. There is nothing left for us here. Let us erase this pointless world, and move on to the next." Chara snapped, and two boxes appeared, One that said "ERASE" and another that said "DO NOT". Something in Frisk, an invisible force, made them slap the "DO NOT" Box. Chara's smile disappeared, as if surprised.
"No...? Hmmm... How curious. You must have misunderstood." Chara's eyes disappeared, leaving a dark void. Their smile reappeared.
"SINCE WHEN WERE YOU THE ONE IN CONTROL?" Their face deformed, and Chara came out at Frisk, their face moving up and down as they almost floated to Frisk.
Chara lifted their hand, revealing a knife, and they swung down with extreme force...
But Frisk dodged the attack. They avoided the strike, and still had 99 HP. Both Frisk and Chara looked confused at the strange action. Frisk hadn't even tried avoiding the knife, they were ready for it, but... why did they move?
"W-what? How did you avoid that? YOU CAN'T CHANGE THE ENDING LIKE THAT!" Chara's face deformed as they screamed. They changed to normal again. They looked... sad. "I just don't get it, Frisk. Why would you kill Mom? Why Papyrus, who gave you mercy? Undyne, the one wanting to PROTECT everyone! Mettaton, the robot every monster looked to for entertainment! Sans! Avenging his brother! Dad? The king who didn't actually want to kill you! And... You killed Asriel... Why? Why are you filled with all this HATE?
"When I attached to your determination, I wanted to help you save everyone... not like this. Your actions confused me, made me mad... then I got that same Hatred. That's why I was able to strike down Sans for you, Why I struck down Asgore. But Flowey? ASRIEL? My best friend... why him? He went through so much to help! WHY?" Chara sighed, before opening their eyes and winking, still frowning. Immediately, the area around them, which was already black, went completely black and white, the color drained from Frisk and Chara's bodies. Chara looked at Frisk and continued. (If you want music, this is where Megalo strike back begins, from around 00:00 to 00:29-00:30)
"I don't care anymore. My original plan was to kill you and erase the timeline so we could get the true pacifist ending, but... If you were able to dodge my attack, then I can't do that. You know what I need to do to you, but... If I need to FIGHT you in order to reset finally..." Chara's eyes turned bright red, smiling again.
"THEN LET THE MEGALOMANIAC STRIKE BACK =)" Chara whipped out the knife, and stared at Frisk heavily. They were still smiling with their eyes burning red. (Cue Megalo Strike back from 0:33 until next cue) (I'd recommend one of the extended versions of the song)
Frisk checked Chara, but there wasn't anything to look at.
"Oh Frisk, don't you know I was the one who was telling you that stuff? And for this battle, you aren't ALLOWED to CHECK." Chara lifted their knife and swung towards Frisk, striking their arm and damaging Frisk: 01/99 HP. Frisk gasped at the pain that jolted through them.
"How'd you do that much damage! What about battles?" Frisk yelled as they stood in pain. Chara laughed.
"Frisky Frisk, we're humans, you aren't fighting a monster... well... if it's that type of fight you want... I AM just Hatred formed by Determination, I'm sure I can make that work for you." Chara winked and Frisk was in a box, like they usually were during fights. "Oh, and I'll make it fair for you. Here's your HP." Chara winked again and Frisk gained 91 HP, ending at 92/99 HP. Frisk looked out at Chara from the box, they were smiling.
"Time to pay for your sins, 'Partner'." Chara lifted their knife and swung down at nothing. At first, Frisk laughed, thinking Chara didn't know what they were doing, but their laughing soon stopped. Large knives appeared at the sides of the box. Frisk stared in fear as the knives came towards them. Frisk dodged them, but suddenly felt a weird sensation in their soul. They looked down and saw that their soul was... light blue?
"Hahaha... Did you think only Monsters used magic? Don't you remember the stories? Humans had strong magic as well. Oh yes, and just so you know what's going on... light blue means you can't jump. Have fun =)" Chara winked and a toy knife the size of Frisk appeared on a side of the box. Frisk moved quickly to the opposite side of the knife as it came slowly in.
They felt a jolt in their back and turned around. Another knife was coming into the opposite side. Frisk's HP was now 65/99 HP. Frisk stayed close to this knife as it inched into the box. Then, it stopped, giving Frisk just enough room to stand in between them. The box disappeared and Chara put out their hand.
"Do what you need, I'm not completely heartless... I am soulless though, so don't think I'll be too nice." Chara tilted their head and smiled at Frisk. Frisk shuddered and reached into their ITEM box. 2 items were in the bag, none Frisk had before. Due to Sans' fight, they had lost most of their items, but in this ITEM area were dog salads, which before Frisk thought only healed about 2 HP. Since they were the only things in the box, Frisk kept them.
Frisk decided to just go with it and attack Chara with the real knife. As they struck down, Chara leaned Into the blade, causing it to strike Chara straight in the face. Frisk stared in awe as they realised what had just happened. Chara's soul had taken the Heart locket from Frisk, they were now wearing the locket. Frisk looked at Chara's HP, which had now appeared above Chara's head: 600/666 HP. Frisk shuddered at the sight of how much HP Chara had. Chara smiled.
"Nice try partner, my turn now." Chara winked again, turning Frisk's soul light blue again. Multiple gloves appeared on multiple sides of Frisk. Down, left, right... there was no way Frisk could avoid the attack. Frisk got as close to the middle as they could, and waited. The left and right gloves backed up, then slammed into the box, but didn't hit Frisk, then the bottom glove backed up, preparing to strike Frisk. Frisk watched as it jolted upwards, when his soul turned blue. Frisk saw their chance and jumped up, avoiding the final glove and saving all of their HP. Frisk laughed with relief as they were safe from that attack. Chara frowned for a second, but then put the smile back onto their face.
"Nice job there, Frisk! You did good! If only you jumped like that when fighting Sans, maybe you could've saved some items! Cause... I'm sure you can tell I'm not going to go THAT easy on you. Don't worry, I gave you a few items that might help." Frisk swung at Chara again, who, this time, avoided the strike. Frisk gasped as Chara smile grew wider.
"You didn't think Sans and you were the ONLY ones who could avoid attacks, did you? =)" Chara winked, but instead of Frisk's soul turning light blue, it turned Brown. Frisk looked at their soul, then back at Chara. "Brown souls, now if you go near the edges of the box, you take damage! Isn't this fun Frisk?" Chara smiled and struck down with their knife, winking as well. Frisk watched as Ballerina shoes appeared at the top of the box. Frisk was prepared to avoid them, when he realised why Chara also struck their knife down. The box shook as it split into four quadrants, making the boxes smaller. Frisk moved to the top left box, since this was the closest and easiest to get to.
Frisk looked up just in time to see the ballerina shoes come stomping down. The only noticeable space to avoid the shoes was near the back of the shoes... which were close to the edge of the box. Frisk took their chances and moved as close to the edge as they could without touching the edge. The shoe came down fast, Frisk was inside the small opening on the side of the shoe, still not touching the edge of the box. The shoe stopped just as the top was about to hit Frisk's head.
The shoe lifted and moved to the lower boxes. Thinking they were safe, Frisk relaxed.
Suddenly, Frisk teleported to the bottom right box, where the right shoe was getting ready to stomp. Frisk tried moving to the side as quickly as they could, but due to Frisk's surprise to the teleportation, Frisk went to far and took 10 damage from the side of the box. The shoe came down and struck Frisk in the head, dealing 25 damage to Frisk. Frisk watched as the shoe disappeared and Frisk was left staring at Chara. Frisk's HP was now down to 30/99 HP.
"I told you I wouldn't be playing fairly, didn't I? Oh, must've slipped my mind." Chara smiled and tilted their head again, staring at Frisk. Frisk reached into their bag and retrieved the dog salad. As they put it to their mouth, they thought for a second. With Sans, they waited until about 1 HP was left, and they only had a 2 items, that probably wouldn't do much anyways.
Frisk put the dog salad back into the box and swung at Chara again, this time hitting them again. Chara's HP was now down to 500/666 HP. Chara frowned at the pain.
"Jeez, you really can deal some damage, can't you? Nonetheless, I'm not just going to give up 'cause of some damage. I need to take you down... you don't deserve life anymore... Dirty Brother Killer." Chara's last words were in a Sans voice, not an imitation, but Sans' actual voice. Chara laughed and winked. Frisk's soul turned brown again. Above Frisk, a book appeared. Pages from the book ripped out and the pages continuously circled around the box, each page following the next. After a second, the pages started firing into the box at high speeds, one after the other. Frisk moved fast to try and avoid all the pages. They moved around in circles, but the pages kept changing directions, making it harder to avoid. After the pages stopped, Frisk was left with 5/99 HP. Chara laughed.
"Still! I believe in You! You can do a little better! Even if you don't think so! I... I promise..." Chara said with Papyrus' voice. "Tell me Frisk, what did Papyrus ever do to you? Make you do Puzzles? No, you skipped the puzzles. Fight you? No, YOU entered the fight with him. You murdered him... for the hell of it. You really ARE an idiot =)" They finished off in Flowey's voice. Frisk reached into the ITEM box and pulled out a dog salad. Frisk ate the Salad. They breathed out with relief. Frisk's HP jumped up to 99/99 HP. Frisk and Chara gasped at the HP change. Chara shook out of their shock and continued.
"You're gonna have to try a little harder than that! The Heroine. What did SHE do? Attack you, for KILLING her friends? I looked up to her... and you killed her like the rest..." Chara winked, Frisk's soul turned Orange this time.
"You know what? Maybe you should figure out what the Orange soul does by yourself. Just don't stop to think too long =)" Chara winked and pans appeared. The pans started smashing the box from different angles. Frisk stopped near the top of the box to avoid a pan, but started taking damage. When Frisk moved to avoid the invisible wall, the damage stopped immediately. Orange soul mode... Orange attacks caused damage when staying still... Orange souls damage when Frisk didn't move! Frisk realised what they needed to do. They avoided the pans while continuing to move, not stopping for a second.
After multiple pans, they stopped slamming into the box.
After the attack, Frisk was down to 70/99 HP.
"You really hate me that much?" Chara said in Toriel's voice. "Toriel was just trying to care for you, and you murdered her like she was just a fly on the wall. No emotion at all... why? Just so you could go through and get this ending. You killed the Monster YOU referred to as mom... just for an ending... Heh, and I thought Flowey was cruel at times." Frisk immediately swung at Chara, dealing 150 damage, Chara's HP was down to 350/666 HP. Chara winced at the damage.
"Imagine how easy things would be if you just SPARED. You could avoid all the death, all the hate, all the heartbreak. You're not even Human anymore. What kind of Monster are you?" Chara finished off with Asgore's voice. Chara winked, changing Frisk's soul orange again. Immediately, a gun appeared on the side of the box. The gun was trained to Frisk, following them wherever they went. The gun started firing, leaving small objects wherever Frisk was beforehand. Frisk bumped into one, causing them to take 10 damage. Frisk kept moving as the gun continued to shoot.
After almost a minute, the gun disappeared, so did the leftover objects. Frisk's HP was down to 53/99 HP.
"Just end it right now. Listen, I'll spare you. Afterwards, RESET. That's the only way to fix everything! If you just RESET, then we can get the happy ending, free everyone, and... things will be a lot easier and happier." Chara stuck out their hand, smiling... politely at Frisk. Frisk looked at Chara's HP, then at their own HP. After a minute of thinking, Frisk swung fast at Chara.
Chara dodged the attack, the strike just hit thin air. Chara sighed.
"I thought you would listen. But... Now I have only one choice..." Chara's eyes turned bright red, their knife turned red as well.
"It's time for my SPECIAL ATTACK." Chara lifted their knife and struck down. The box grew smaller with every strike. Soon the box was just small enough to fit Frisk in the box. Chara laughed.
"Well Frisk, it was fun, but don't come back." Chara struck down, dealing 50 damage to Frisk, leaving them at 3 HP. Chara frowned.
"I... I..." Chara collapsed. They started crying.
"Frisk... why? Why did you go and kill everyone? Why did you kill my... my family? The ones that cared for me. Toriel cared for you like she did to me, and you murdered her. Papyrus wouldn't fight you, and you squashed him. Undyne attacked you BECAUSE you killed everyone, and they melted. Sans was just trying to avenge his brother's death... and he's gone as well... Why? Why did you kill EVERYONE? Just for fun? Just to get an ending? WHY?!" Chara continued to cry. Frisk, who didn't seem to show any emotion at all, swung at Chara, dealing 250 damage, leaving Chara at 50/666 HP. Chara sniffed and laughed.
"See? Y-you're heartless. You don't even care if I'm crying, you'll STILL kill me, just for the ending... I don't WANT to kill you, Frisk! I liked you, every pacifist ending, you were so kind! Come on! Accept my Mercy and let's reset! Please!" Chara put out their hand again for Frisk. Frisk swung at Chara, but they dodged the attack.
"Frisk this isn't a question, this is a demand, PLEASE reset!" Frisk swung again, this time landing the blow on Chara. Dealing 500 damage to them. Chara gasped at their defeat. Chara's chest had a large gash through their chest, which they grabbed.
"Ha... ha... well... I guess I couldn't get you to accept my mercy. Pity." Chara slowly stood up, staring at Frisk with an honest smile.
"Thanks for allowing me to be your partner, it was fun... welp. Anyway, I'd like to go join Asriel now... sadly I can't though." Chara lifted their hand from their gash, revealing that Frisk's cut was healing. Chara smiled again and their eyes turned red.
"You do know you can't kill ghosts, right? Hahaha... Technically Frisk, I'm still a ghost, I'm the ghost of your DETERMINATION, so... I just put on a show for you to have some hope. I was trying to stall you so I could explain what you did... maybe get you to reset on your own... I guess you're too predictable though, you just wanted to kill me once and for all.
"I bet in another timeline, you spared me somewhere along the way, and we reset together. I was nicer to you for actually listening... You don't get that special treatment." Chara lifted their knife into the air.
"I asked you before, and I'll ask again Frisk.." Chara's eyes turned into a void again.
"SINCE WHEN WERE YOU THE ONE IN CONTROL?" Chara's face deformed and they struck Frisk with extreme force. A blinding light filled Frisk's vision.
Everything went black.
Frisk couldn't come back.
Someone else was in control over the save file now...
