Previously: The Order of Seven generated a field to exorcize a Dark Demon that had been possessing Chara Dreemurr, the first human to fall down into the underground, then Deos the Determined, Undyne the Undying, Sans and Mettaton NEO fought a fierce battle against it unfortunately it regenerated each time it was damaged, thankfully that battle was intended to buy the others time to charge their magic, which ended with a cliched scene that would've been worthy of part of Dr. Alphys' anime collection where a white beam combining the Order of Seven's magic eradicated the Dark Demon for good. When they returned to the Throne Room, they found that Chara was starting to fade, thankfully Deos had a plan involving the blood of Asgore and Toriel, along with a spell similar in appearance to the one that he used on Asriel...
(Throne Room)
Chara started to open their eyes, for some reason they were finding it hard to focus, although they could hear some voices.
"Good, they are awake" He recognized their Mom's voice, she always worried a lot about them...
"Are you sure that they're okay?" He knew that was Asriel, what a cry-baby...so was Dad...they could now see clearly and saw a ring of monsters and humans looking at them with a mix of concern and unease, what could make them feel uneasy.
"Chara, how is everything going in there?" Deos asked.
"F-Fine...you saved me...why?" Chara asked back.
"Yes, I saved you, but it wasn't without side-effects..." Deos said, slightly nervously.
"Why?..." Chara said as they moved into a sitting position "What side-effects were..." Chara was about to ask when they saw that they have paws...white fur...huge white feet. "There?..." they checked the rear and yes...there was a tail and on their head was huge floppy ears and they felt that they had a muzzle and fangs, this made Chara wide eyed with shock and open mouthed as what has just happened has sunk in. "You turned me into a boss monster?!" Chara shouted in a surprised tone.
"It seemed like a suitable punishment for what you've done..." Paula said.
"Punishment?!" Toriel said, in an alarmed tone.
"Let's see...they poisoned their father, attempted to use Asriel as a tool for killing those that had driven them down here and got both of them killed and causing lasting damage to you and Asgore, all because they couldn't let go of their hatred for humanity, a hatred of their own flesh, a hatred that the demon that used to be inside of them brought to the surface and amplified." Deos said, while looking at Toriel.
Paula then brought out a small mirror and Chara could now see their new body, they still had the hair that they had when they were human, along with the rosy cheeks and the red eyes, along with the green long sleeved shirt with a single yellow stripe and brown pants, but now they were a bipedal sentient goat who wasn't wearing any shoes, much like their brother and their parents, they were still in shock with what was their new body.
"You seem to take more after your father in looks, Chara...much like Asriel takes more after his mother." Deos said.
"Really? I've never really thought about that..." Asriel said.
"Around this time, in the best-case scenario, you would've absorbed almost all the souls of the underground and the six human souls and turned into the 'absolute god of hyperdeath', which is basically you fully grown, you had horns that were more slender than your Dad's...oh yes, I almost forgot to say this..." Deos said, while turning to Asgore and Toriel. "Now that Asriel is back and, thanks to your contribution, there's a spare, the two of you are now aging again...agh..." Deos said, while looking at Asriel, who was then interupted by a hug from both Asgore and Toriel.
"Thank you!" Said both Asgore and Toriel.
"Too...tight..." Deos said, trying to breathe, they let go.
"Sorry, I will need to watch what I do around humans in future, as I could kill them without intending to." Asgore said, sounding embarrassed.
"I'll let you go on this occasion..." Deos said, as he catches his breath.
"We certainly did, isn't that right, Gorey?..." Toriel said affectionately, making Asgore blush, she then switched to a more serious tone "Why did you bring Chara back as a boss monster, not that I am complaining that you saved them..." choosing her words carefully.
"It's because I couldn't bring them back as a human, that would've require their human parents, who have been dead for some time..." Deos explained "I remembered something about the Mages that set the barrier up, finding some monster infants, basically war orphans and since their parents were most likely killed or otherwise rendered inaccessible by guards around Mt. Ebott, they decided to perform a ritual for those who couldn't conceive naturally, they were turned into humans using the blood of their parents and fed with determination channelled by them as one of my predecessors literally worked their magic, what I did to make it work here was inverted the formula, replacing determination with hope, compassion and love."
"You got a second chance at life, Chara, don't mess it up." Simone said.
"I deserved to die!" Chara said, with self-loathing in their voice.
"Chara!" Toriel shouted in shock.
"I mean it! Why do you care about me, when I've caused you so much pain! You've been great parents to me, better than I truly deserve!" Chara said, the emotional beating continues.
"Please stop saying that!" Asgore shouted, as Chara looked at Asriel, who had no hatred in his eyes, only worry about the child who is now fuzzy.
"You've been a great brother to me, you didn't have to be...you still care about me?" Chara said, with confusion in their voice.
"Of course, I do! We can't do anything about what happened before, all we can do is move forward." Asriel said, Chara can see that he meant every word.
"Then why do I feel like pointy things are stabbing me?" Chara said.
"That's...guilt, Chara." Alec said.
"How do I make it go away?!" Chara said, they look almost unable to take it anymore.
"You need to let go of it, you spent your life as a human not feeling it, as you were devoid of compassion, something which humans can have, but don't particularly need. Now that you're a boss monster, you filled to burst with compassion and you feel that you've wronged your family, but they don't hold it against you, they just want to pour their love onto you, because they want to show you that they still love you, regardless of what you've done to them." Alec explained.
This did it for Chara, they couldn't hold back the tears any longer, they rushed to their parents who gladly hugged them...with Asriel and Frisk quick to join them, Chara started to feel a great weight lifted from his soul, the others felt better about this as Chara turned to Frisk.
"Frisk...I don't know what you've been through to be driven down here, but you've dealt with coming here different to how I did, you don't like the use of violence, even if it's self-defence. You feel merciful, even when everyone is trying to kill you...I don't know if it means anything but..." Chara said, then they hugged Frisk "You're a better human than I ever was." the tears kept coming, they thought about it and they realized that they're now just as big a cry-baby as their father.
"Thank you for saying that, Chara." Frisk said.
"...AND THAT'S A RAP!" Mettaton said.
"Good, I can take this off now...what are you two smiling about?" Deos asked, as Asgore and Toriel were laughing at the sight of Neil, Alec, Paula and Cali, Deos could see that they were kneeling down to pet Asriel and Chara, both with embarrassed looks on their faces, Deos wasn't amused by this, although he wasn't surprised about this.
"I can't stop myself, you're both so cute..." Cali said, with a smile on her face.
"I agree." Alec said.
Asriel looked at Chara "Chara, is this how some humans react to any that look like us?..."
"Why are you asking me, Asriel?" Chara said, while trying not to pay attention to the attention that they were getting.
"You used to BE human." Asriel asked.
"Yeah...and not a good one." Chara said, regretful of their past actions.
"Well, you seem like a better monster." Neil said.
"So, start acting like one." Paula said.
Then Chara had a surprised look on their face, this alarmed everyone.
"Chara, what is wrong?" Toriel looked at him worryingly.
"I was thinking of Snail Pie...when I was human, I thought it was gross, now..." Chara is unable to complete that sentence, although they could guess the rest of that sentence.
"I see that you've gained your mother's craving for snails..." Deos said.
"WHAT?! I'll start LIKING snails?!...this is certainly going to take some getting used to" Said Chara, initially disturbed, but resigned to the fact.
"I'll head to Waterfall and pick some up..." Toriel said, excited that Chara likes them now.
The Order of Seven then put their masks back on and Deos then makes the device visible for all to see. "Mettaton, you might want to be showing this next bit, as this is the moment that you've all been waiting for, although not exactly as you thought it would go."
"I'LL MEET YOU ALL AT THE BARRIER, DARLINGS!" Mettaton said, as he moved ahead.
