Previously: A heartfelt reunion between Asgore, Toriel and their long dead son, Asriel and the broadcast of this by Mettaton (along with the rest of the Order of Seven and a few other monster witnesses) then Deos brought his Order along with Sans, Mettaton and (reluctantly) Undyne with him to perform an exorcism on this demon in the ruins, a demon that was in the resurrected Chara, who was brought back with Asriel...
(Ruins)
As Chara Dreemurr, the demon possessed human adopted by the ruling boss monsters in the underground, was charging at Deos, Red Mage of the Order of Seven, he made the other six of his Order appear in a circle, with Sans and Undyne right behind him. The others created a barrier which made Chara feel not so good.
"Surprise!" Deos said, Chara starts to collapse in pain.
"You..." They said, with growing hatred in their voice.
"We're not interested in destroying you, Chara! It'd break your family's hearts and I don't wanna tell them that you're dead, AGAIN!" Undyne said with surprising restraint.
"Yeah, we want what's making you a threat to all reality." Sans said.
"It's not up for negotiation..." Deos said, as he added his own power into the mix, which started to draw out a black smoke from Chara, who was screaming in pain as it was drawn out of them, when the last of the demon was exorcised, Chara collapsed and Sans quickly got to Chara and warped them away from this location and just as the black smoke was solidifying into something spiked and evil looking, a combination of "The Scream" painting and something out of a Heavy Metal album cover, Sans warped back.
"Chara's safe, but is out cold, they should be alright for now." Sans said.
"Good..." Deos said and then looked at the others, who have stopped generating the field that made the Exorcism possible. "Get into position."
They nodded as they followed the plan they they had agreed to, for this situation. Mettaton then flew down and stood with the others.
"SO, THIS IS WHAT MADE THINGS WORSE FOR US AND IT HID IN SUCH AN INNOCENT LOOKING PACKAGE" Mettaton said.
"They always look so innocent, right until they get the point across." Sans said.
"...I'll let that one pass as I've got a point to get across myself" Undyne said, who then made a spear appear in her hands.
"This time, none of us will need to hold back! We can't let it get back to Chara, otherwise this will all be for nothing, whatever happens...this ends here and now!" Deos shouted.
"RRRRRREEADY! IT'S SHOWTIME!" Mettaton said, who made a flash of light "OH YEAH!" He shouted in his signature way, when the lights came back on, the Dark Demon had before it Deos the Determined, someone who won't tolerate the innocent being threatened and one you do NOT want to anger, Undyne the Undying, an emotionally intense lesbian fish monster who would be the ultimate bed-wetting nightmare of any sushi chef, who now had spikier hair and hearts on her gauntlets and her chest plate and a small spear on the previously covered eye. Sans, an undead being without any meat on his bones who's lazy and joking personality was just a front for a broken man who saw his actions as pointless until recently. Finally, we have Mettaton NEO, a ghost in a robot body who has recently been outfitted with Demon Eradiator weapons and a more human looking appearance, who appeared like a glam rock singer combined with a video game robot.
"I still have enough power and determination to destroy all of you! Then I shall reclaim my puppet and finish what I started! All shall be destroyed, over and over again for all eternity!" said the Dark Demon, a voice that was as echoing as it was malevolent.
"Threatening us all..." Sans said, who then had his eye sockets hollow "You're gonna have a bad time!" he said in a deep intimidating voice, who then proceeded to pelt the demon with Gaster Blaster lasers and bones, combined with gravity shifts, most of which hit and considering that it was a demonic being, it also burned with something purple.
"Woah, you kicked its dark a**! What was..." Undying the Undying said, impressed by Sans' performance that was previously unknown to her.
"Karmic Retribution, the greater the sins, the heavier it hits." Sans explained.
When the smoke cleared, the Dark Demon was still standing and it swung its arm at Sans, which Undyne the Undying blocked with her spear and then parried to leave it wide open to attack, which she followed with a barrage of spears, which hit hard and pinned it to the wall.
"You're gonna have to try a little harder than THAT!" Undyne the Undying shouted. Then Mettaton NEO, sent a barrage of Mini-Mettaton bombs to explode on it, finishing with a few volleys from his arm cannon, it reformed after that damage.
"IT'S REFORMING, I GUESS WE'RE THE ONES WHO NEED TO TRY HARDER!" Mettaton Neo said.
"Then let's try harder, then!" Deos the Determined shouted, He attacked with Undyne the
Undying delivering a Mace / Spear combo, which furiously pounded the Dark Demon into pulp, who proceeded to whip both of them to the other side of the room, incapacitating them briefly. Sans and Mettaton dodged out of the way and decided to deliver a Gaster Blaster / Arm Cannon combo to further damage it, all this did was give the other two time to recover, it then swung furiously at Sans and Mettaton NEO without success as they dodged effortlessly each time as Mettaton NEO used his legs to counter-attack it by kicking it repeatedly.
"It keeps reforming! How are we able to beat it, if it keeps coming back for more!" shouted Undyne the Undying.
Deos looked behind him "That's still charging, we need to buy the others more time."
"THEN LET'S KNOCK 'EM DEAD!..." Mettaton NEO said.
"I won't say what I'm thinking as it would be a little insensitive towards you..." Deos the Determined said.
"Do you see how futile your efforts are? I will keep coming back again and again, until you all tire yourselves out, then I shall destroy you with minimal effort and then everything else shall follow!" The Dark Demon said with hatred in his voice. Deos the Determined then blasted him with a strong red beam out of his hands, which Mettaton NEO and Sans joined him in with, along with Undyne the Undying with her spears, Deos the Determined was thinking that Dr. Alphys must be watching this right now and is having a nosebleed AND finding it hard to breathe with all the excitement that's happening, even though she knows that they're in danger.
"Enough with the villain monologues already! Make it easier on yourself and give up!" Said Undyne the Undying, while looking at her D-T Regulator, it was nearing its limit, this was worrying, but she won't leave too soon, she'll buy as much time as she can with what she was left to work with, Sans doesn't look too good, he's been sending bones to collide with the demon and using his Gaster Blasters in more precise ways, while dodging the arm swings, he's starting to look tired, Mettaton NEO isn't looking too good either, even with the time that Dr. Alphys had to modify him, his power supply won't last much longer either, so she sees that she needs to make her next move count. Deos looks at her, he understands what he needs to do.
"Do you know what would happen, if I used my magic to augment yours temporarily?" Asked Deos the Determined
"No." Said Undyne the Undying.
"Nor me, let's find out!" Deos the Determined said, as he put his hands on her shoulders, while standing behind her and used his magic on her, she then made giant spears appear above the Dark Demon, who pulverised it, much in the same way as she would her cooking, it was a pile of goo when she was done and it was reforming again, the D-T Regulator was near the critical point, Deos then looked back and he could sense that they were almost done charging, then a dark tentacle swung at both of them, then a white laser appears to blast it back, this was coming from a Gaster Blaster.
"Time to whip you into shape!" Sans said, much to the displeasure of the others, along with Papyrus, who was probably watching, he was looking tired.
"Get her out of here, Sans...you two have done enough." Deos the Determined said.
"Gotcha..." Sans said, as he grabbed Undyne and started to warp both of them out.
"I can still take..." Said Undyne the Undying as she was interrupted by them warping out of the ruins.
"Mettaton NEO, let's retreat to the next room, I want you to show what's next." Said Deos the Determined. He then ran to the next room and Mettaton NEO followed not long after, in the next room, the Dark Demon was fully reformed and angry, it was then met with Mettaton in his based form and the seven mages of the Order of Seven lined up with formation.
"The Captain of the Royal Guard and that deceptively lazy Sentry is gone, your ability to resist me is much lower, what hope is there now?" said the Dark Demon.
"You've definately got a couple of those, if you wanna take us on!" Simone shouted.
"Justice shall be served by your destruction!" Paula shouted.
"Kindness is clearly beneath you!" Alec shouted.
"Let's see if you can keep together after this!" Lara shouted.
"You're a patient force of destruction, even mine has limits!" Neil shouted.
"We'll keep going until you're gone or we are!" Cali shouted.
"...and to finish this off..." Deos said, as he quickly charged his magic "we give you the worst cliché in the underground, a finale that is definitely grand and the last word you'll hear from us!" he shouted and then they all focused their magic into one point to create a white beam, brighter than anything Sans can create with his Gaster Blasters.
"BEGONE!" Said the Order of Seven as the concentrated blast of magic tore into the demon, slowly and painfully making it dissipate.
"YOU CANNOT DESTROY ME! I AM THE DESTROYER! I..." said the Dark Demon as it was finally vanquished, they all caught their breath before any of them talked.
"We'd best head back to the throne room..." Deos said as he went back to normal, the others silently agreed, he warped them back there.
(Throne Room)
They suddenly appeared and they were all relieved to see them safe, Papyrus was hugging his brother since he came back intact, Undyne was being seen to by Dr. Alphys, who was showing no ill-effects from using Determination, after it was purged from her system...for now, although the Dreemurrs were another thing entirely...
"Everyone, something's off with Chara!..." Deos said, as they all saw that although they were awake, they seemed like they were starting to break apart, like they was fading away in parts, showing their red soul.
"I guess not everyone can be saved, after all...he he." Chara said, bitterly.
"Is there nothing that you could do for them?..." Toriel asked, with tears in her eyes.
"There is, but I need the two of you to do something..." Deos said, with a serious look in his eyes.
"Name it!" Asgore said, in an unusually commanding voice.
"I need you to bleed a little on Chara, trust me, I can use that to save them." Deos said, they did so by cutting each other to bleed a little on Chara, Toriel then proceeded to heal both of them.
"What now?" Asriel asked, worried about their sibling.
"Everyone, move back! Asgore and Toriel, channel your hopes, your compassion and your love towards Chara" Deos shouted, they all complied, Mettaton was recording this intently as he used his magic on Chara, who was engulfed in a white light, similar to the one that Asriel was, when he was Flowey, they were all confused as to what he meant by saving Chara...or rather all the monsters, the Order of Seven knew what Deos was doing...
How is Deos intending to save Chara? What will this mean for the underground? What else is left for them to do? Find out in Chapter 30: Irony and Change
