Yay! Update!
I tried to have this done for before the new year, but oh well. Happy new year!
I do not own Undertale or any associated AU's
The child held their hand out to Chara and asked them a single question, "Are you willing to see what lies in the original world?"
Chara hesitated for a moment before walking up and taking the hand held out to them while asking a single question, "What is your name?"
The child smiled as they responded, "My name is Frisk."
Frisk then placed their intertwined hands on the RESET button, which caused the black void to completely consume them for a moment, before Charas eyes opened, staring at a cavern ceiling whilst lying on a patch of flowers.
Chara looked around to see the Frisk sitting there in the same purple/pink shirt that the person who killed their brother wore. Though that made sense as it seemed that they had been possessed.
"So Chara, before we go anywhere I am going to explain the differences between this Timeline and yours."
As Frisk went over the differences Chara was in shock, from what Frisk had learned from the RESETs and the other Charas memories, in this timeline Charas family was the royal family, and Chara was supposed to be dead.
As Frisk brought their explanation to a close, Chara let out a breath and rubbed their face.
"So, let me get this straight," Chara said to settle their thoughts, "Asriel is dead, Mom is the caretaker of the ruins, Dad is the one trying to break the barrier with SOULs, King Sans is a lazy skeleton who can teleport and remember these... repeats, and Prince Papyrus is a Royal guard recruit."
They looked at Frisk and asked, "Is there anything that I missed?"
Frisk seemed to think for a moment before shaking their head.
Chara sighed in relief before they looked at Frisk and asked a question that had been bothering them, "What happened to the other Chara?"
They asked this because they had a hard time connecting the genocidal psychopath they had seen, with the person that sounded very much like themselves. A child who loved monsters and disliked humans. How do they go from that to someone who will kill everything they used to love for power?
Frisk looked at the flowers the two children were sitting on for a moment before they spoke, "I was stuck with the other Chara for a long time, from what I could see in their memories they originally helped other versions of myself get their happy endings. However," Frisks face turned grim as they continued, "At some point they latched on to a version that didn't care and killed everyone, then they kept getting those kinds of people."
Chara had a look of horror on their face as Frisk continued to speak, "After a few dozen of the genocide paths, they finally got another Pacifist. Unfortunately it was too late, Chara had snapped from seeing the people they cared for die over, and over again. They started possessing each new person that they latched onto and attempted to make them suffer through what they had."
"The genocide of the Monsters." Chara said.
Frisk simply nodded and continued, "After a while each person they latched onto would fade away and cease to exist, I was the latest one who they had attached to. I also lasted the longest out of any before I took them out."
Chara looked at Frisk, hearing the tone in their voice, and decided to question them about it, "So, why do you sound like you regret it?"
Frisk went silent for a moment before answering, "I'm a pacifist at heart, I will fight if I have to but I dont like it, and I knew that Charas past, I don't so much regret destroying them as I do feel sad for who they once were."
Chara stayed silent after Frisk said that, what can you even say in response to that. The silence didn't last all that long since Frisk stood up after a moment and walked off of the flower bed before turning to speak.
"We should get going," they said, they then gained a smile that unnerved Chara before they continued, "Unless you want to spend more time sitting on what is technically your own grave?"
Hearing that quickly got rid of any feeling of comfort that this patch of flowers gave as Chara leapt to their feet and all but sprinted to the exit of the room. They vaguely heard Frisk laughing as they went towards the door.
Flowey was staring up at the ceiling of the cave he always appeared in at the start of any RESET. He was starting to get sick of this room, but he always stayed to see the child pass by and meet Toriel before leaving. Mostly because he was afraid that Chara would kill him early if he so much as twitched wrong.
As he waited, he thought back on the day he discovered the truth of who the human was, boy was he surprised.
Flashback
Flowey sighed as he saw the human go off with Toriel. He was beginning to wonder if this was why the Smiley Trashbag was so depressed all the time, because there was really nothing that could be done to change what happens when someone else has the ability to RESET.
He was about to burrow away from the patch of ground when he heard the sound of someone entering the room. Confused, Flowey turned to look at who came into the room, only to gape at the sight of a near clone of the human who had just come through.
What the human said next only increased said confusion.
"Hi Flowey, nice to finally meet you when I'm not being possessed by Chara. My name is Frisk."
Flashback end
At least that meeting had answered why he was remembering so many timelines that should have been erased by the jumps to new timelines.
Chara couldn't create a True Reset, they might have enough Determination to use the SAVE ability but because of the fact that they possess others, they don't have enough determination to erase the memories of those who can retain them over normal RESETs.
Flowey looked away from the ceiling when he heard two voices coming towards him, and it didn't sound like two people trying to murder each other, so he was hopeful.
And slightly entertained by what he was hearing, as well.
"Come on Chara, it was a joke."
"Yeah, well then you have a twisted sense of humor! If it weren't for the fact that I don't want you dead, I would have stabbed you for that!"
Flowey was actually curious as to what joke Frisk made to piss off whatever, very strange, Chara that was there with them. He was also curious about said Chara, but they were coming towards him, so that was less important at the moment.
"What, pointing out that you were sitting on your grave?"
Yeah that would piss someone off if they hadn't known that before hand.
The footsteps sped up as a laughing Frisk sprinted into the room, followed by a hoodie wearing Chara chasing Frisk with their hands out, most likely trying to stangle them.
At least their appearance answered which Chara it was, Flowey never could enter some AU's he never figured out why, one of which was Storyshift.
He watched as Frisk made Chara calm down by apologising before he appeared, he didn't bother with his false kindness, Frisk wouldn't fall for it.
"Howdy Frisk."
The sound of his voice jolted the two humans to look at him, when he knew he had their attention he decided to just cut to the chase, "I'm only going to say this once, Frisk. Now that you are free it's time to finish this little tale of ours, by the end one of us will have our way. Either the monsters will be free, or I will have reclaimed the SAVE ability," that wasn't quite true, he would free them anyways but then he would probably return to messing with the timeline for fun, "See you later."
He turned to burrow away, but a false cough caught his attention and he looked back at the humans.
As a result he saw what he considered the scariest thing in existence, Chara's scary face.
And for a moment he wasn't Flowey the Flower, he was Asriel Dreemurr, and he was absolutely terrified as he plunged into the ground and dug for his life.
As they watched the flower run for his life, Chara turned to Frisk with a serious face as they asked, "Why didn't you tell me?"
Because if the reaction that flower had wasn't her brothers normal reaction to her scary face, albeit slightly worse because of her intent to actually threaten the damn flowers life, then she was misremembering.
Frisk understood the question that was asked, however they dodged it for the moment with their response, "I'll tell you why once we get to somewhere we can sit and have a long conversation."
Charas response was cut off by the arrival of a familiar, furry face. "Well, hello there children, I am Toriel, I am the caretaker of the...Ruins..." Toriel trailed as she saw Charas face, causing them to remember that they were supposed to be dead in this timeline.
Toriel cut off their thoughts as she spoke in a near desperate voice, "Chara?"
They stuck their hands in their pockets and hunched their shoulders along with having a sheepish smile as they responded, "Hey mom."
Both Chara and Frisk realised that many explanations were going be required, including timeline explanations that they would probably need help from Sans for.
Frisk was not looking forward to any part of this.
As a better explanation, the other Chara could not properly do a True Reset because part of their determination was used to possess their current host.
For those who are curious Flowey cannot access timelines where Asriel is the person there because of them being the same person, but the other Asriels have souls and aren't capable of coping with RESET levels of Determination. Also, the moment of Flowey saying he was Asriel was meant to show that he acted like Asriel for a moment of fear, that's all, he didn't turn back to asriel or anything like that.
