Time Trio! Time Trio:

Phase 0: During the Karmatic Time Trio's final phases, when Kyuuseishu was using the rift to attempt to transport the human to different Trios to wear them down before beating them, Kyuuseishu would create a rift designed to go to Murder Time Trio but accidentally made it so it would also simultaneously go to Hope Time Trio. This would result in the rift becoming corrupted and fusing the three different timelines, Karmatic Time Trio, Murder Time Trio, and Hope Time Trio together. This corruption proved also resorted in each timeline resetting themselves, leading to the Karmatic Time Trio losing their ability to create rifts for now as Kyuuseishu now no longer exists.

The 2 other Trios would end up in Hope Time Trio's Timeline, being in the True Lab next to the Determination Extractor for whatever Call of the Void (CotV) Sans said they're planning to do with it. Due to the mixed motivations between the trios; Murder Time Trio wanting to exterminate the human, Karmatic Time Trio wanting to give the human the Karma they deserve for the actions they've taken, and Hope Time Trio still believing that the human can change, wanting for them to reset and choose against the Genocide path rather than for it - the three Trios wouldn't initially want to team up together, instead fighting separately.

Even though the Timelines had reset, the corruption from the rift still remains as every so often a rift would suddenly form to another Timeline causing a new Sans to appear to join the fight. Also, the Timeline merge caused the properties of the 3 humans from each Trio to fuse together, creating a human much stronger than each respective Trio's human.

Phase 0.5: The three different Trios not wanting to team up decide which Trio will face the human first. Murder Time Trio declaring themselves as the strongest one forced the other two Trios to let them go first, with Karmatic Time Trio going second, and Hope Time Trio going last.

So the order in which the Sanses will battle in Phase 1 is determined: Murder Time Trio: (Dust Sans, Killer Sans, Horror Sans), Karmatic Time Trio: (Last Breath Sans, Karma is a B1#ch Sans, Hardmode Sans), Hope Time Trio: (Call of the Void Sans, Tears in the Rain Sans, Distrust Sans).

Phase 1: Murder Time Trio would go first against the human, but as the fight would continue the Sanses would grow more and more tired from battling until the human is given a chance to make an attack. This moment is interrupted however as the next Trio, Karmatic, steps in to fight the human, relinquishing the human's opportunity for attack. As Karmatic Time Trio is growing tired like Murder Time Trio did, the human sees another chance at attack before being interrupted by Hope Time Trio who step in for their turn at attack. But once more, Hope Time Trio would also run out of stamina eventually, and with nobody to step in to save them, they take a hit.

Phase 1.5: After the human makes their attack against each of the Sanses of Hope Time Trio, CotV Sans dodges out of the way, but Tears in the Rain (TitR) appears to be too tired to move, so Distrust Sans steps in front of them in an attempt to block with their big bone. However the Bone would break into two parts from the attack, resulting in Distrust getting slightly damaged. Distrust Sans seeing the human's extent to hurt people first hand, nearly killing TitR Sans, and also causing them damage Distrust loses complete trust in the human, making an all out attack in the next phase against the human. Before we arrive at the next phase, CotV Sans activates the Determination (DT) Extractor, stealing around half of the human's Determination that is then used to summon Gaster to help alongside CotV in the later phases of the fight.

But after the human is done with Hope Time Trio's attack, they find the other two Trios standing by and attack against them as well. For Murder Time Trio, in the time allotted between the end of their attack in Phase 1 and the actual end of Phase 1 they were able to regain their stamina so they could all dodge the attack. All except Horror Sans because they're immortal so it would've damaged them anyone. Unluckily for him however, the Murder Time Trio human's abilities just so happen to become active right now, with one of them being deletion which is used on Horror Sans, erasing them from existence. In Horror's a place, a rift to the INSANITY!Tale Timeline forms, resulting in Insanity Sans being brought to the Time Trio! Time Trio, joining Murder Time Trio in place of Horror.

Now for Karmatic Time Trio, everybody except for Hardmode Sans dodges leaving Last Breath, and Karma is a B1#ch safe. But as for Hardmode, they would not be able to sustain the hit, dusting away. Before Hardmode Sans fully dies with their soul breaking, CotV Sans decides to take it and store it in the DT Extractor for potential later use. It is then that a rift would form to a [No AU] Timeline involving Ainavol who would be transported here to the Time Trio! Time Trio, deciding to join Karmatic Time Trio, replacing Hardmode's role.

Phase 2: All three Trios realize that fighting with only their own Trios wasn't the best idea as opposed to dealing with it and fighting alongside each other. So now Murder Time Trio, Karmatic Time Trio, and Hope Time Trio all team up together to fight the human. The roster here consists of: Dust Sans, Killer Sans, Insanity Sans, Last Breath Sans, Karma is a B1#ch (KiaB) Sans, Ainavol, CotV Sans (phase 1.5), TitR Sans, and Distrust Sans (phase 2). Nearing the end of this phase, Distrust Sans does get the chance to make a devastating attack against the human, however their empathy for believing that deep down the human can still change prevents them from making the attack. This refusal to truly hurt the human makes Sans lose trust not in the human, but in themselves for not being able to finish the job. [Continuation in Phase 2.5]

Phase 2.5: All 9 Sanses get tired once more, giving the human another chance to attack against everyone. All of Murder Time Trio, Dust, Killer, and Insanity Sans are able to dodge the attack once more. But for Karmatic Time Trio, Last Breath and KiaB would end up getting hit. Instead of simply dying like Hardmode did, Last Breath gets protected by Gaster leaving them at 0.01 HP. As for KiaB, they would realize that if they can use the effects of Karma on the human to hurt them since they've done bad things, then if Sans used Karma on themselves having not done any bad things, then instead of getting hurt, they should get healed. Upon going through this plan, it'd prove effective. KiaB Sans wouldn't die, and the Karma would keep them alive, as well as improving their Karma abilities as a whole. Another rift would then form leading to Undertale: Betrayer resulting in Betrayer Sans being brought into the Time Trio! Time Trio Timeline, and joining Karmatic Time Trio turning it into a quartet. Then for Hope Time Trio, Call of the Void Sans would get hit, but thanks to the rift corruption as well as CotV Gaster's presence, a glitch ended up reverting the attack making them stay alive. TitR Sans wouldn't be so lucky however, as they would end up getting hit with no Distrust to block and no glitch to undo. This is then where CotV's plan would take into action: they would take TitR's soul, and imbue it with the Determination stolen from the human by the DT Extractor in Phase 1.5. As for Distrust Sans; They would eventually remember that they're the Magnificent Sans, a soon-to-be Royal Guardsman who will give it everything they have to defeat the human. This sudden rush of motivation would linger in the Magnificent Sens's soul, lingering on a specific part of their soul, this part reflecting on the experiences, memories, and feelings they have for their brother, Papyrus. This causes a copy of Papyrus to be brought back to life to fight alongside their brother, Distrust Sans.

Phase 3: The Sanses, having tried being split into their respective Trios, as well as all teaming up together with each plan failing, decide to try a third strategy: 1v1 the human for each of them. So for each Sans they'd get their own Phase 3 for battling the human in this order: Dust Sans, KiaB Sans, TitR Sans, Ainavol, Last Breath, Betrayer Sans, CotV, Insanity Sans, Distrust Sans, and finally Killer Sans.

Starting with Dust Sans, they'd summon their Phantom Papyrus to help them alongside the fight. Other than that, they lock the hell in without the distraction from the other Sanses or Trios interfering with their direct battle, as is for each of the other Phase 3's. In the end of Dust's Phase 3, they end up getting hit which will be dealt with later.

For KiaB Sans, they use their newly reinforced Karma abilities as their main gimmick, but otherwise not much I can say for specifics. At the end of the phase they would get hit, so they would take a syringe, stab it into the human to steal even more of their Determination, and inject it back into themselves to keep them alive despite the two hits they've already taken.

Now with TitR Sans, they use the most of their Determination (given to them from CotV imbuing their soul with the stolen Determination in Phase 2.5) to give an all out attack against the human. Otherwise, like the others, not much I can say in detail specifically. They do get hit at the end of the fight leading to their death, but CotV Sans takes their soul in plan for what they're going to do during their Phase 3.

Time for Ainavol who spends the first half of the fight on their own, until another rift opens up to another [No AU] Timeline holding a Sans known as AGEM who teams up with Ainavol for the second half of their Phase 3. They as well as AGEM get hit, but they're able to tank it at least for now.

For Last Breath, they gain a bone like what Distrust had in phase 1, allowing them to parry attacks, as well as use it more directly for physical attacks. Gaster also lends their assistance throughout the battle. They get hit at the end of their fight like everyone before them, but it's protected by Gaster who has taken their influence over Sans, with Gaster now using Sans directly to attack the human.

As for Betrayer, they're not too special. However halfway through their fight they get attacked by the human, but they don't die having remembered Papyrus and gain a sense of empowerment/Determination to continue the fight. Unlike all before them, as they're about to get hit by the human at the end of their Phase they move out of the way, dodging the attack.

It's time for CotV Sans who uses the DT Extractor again, imbuing it with TitR's soul in plan to take the Determination from their soul and transport it to Hardmode's soul, bringing them back to life, but in the form of a Lost Soul. CotV and Lost Soul Hardmode would team up against the human, and nearing the end of the fight the human would make their attack, but CotV would go behind Hardmode because no Lost Souls can't be damaged. Soon after this happens though, Hardmode reverts from the Lost Soul status bringing them back to normal.

With Insanity Sans, they don't hold back at all, giving almost too much to defeat the human that causes their soul to burst from their chest from all of the power they're exerting. But the result of their soul bursting from their chest allows them to use however much of their power they want without any present repercussions. These repercussions would come later though as when the human makes their attack, it hits with Insanity taking it becoming severely weakened at the end of their phase.

For Distrust Sans, they and their recently re-alived brother, Papyrus ignore the threat of the human battling them and just hang out with each, playing games that lead to the human being stuck in their crossfire of the brother's fun. But after enough distractions, at the halfway mark of the fight Distrust realizes that if they could bring Papyrus back to life, then maybe they could bring somebody else. This somebody else being the head of the Royal Guard, Alphys. But the reality of Distrust Sans alongside Papyrus and Alphys is short-lived as at the end of their Phase they realize that the Papyrus and Alphys weren't real, and then lose all motivation. The human would make their attack as to which Sans would block with one last hope that the human can change for the better, giving everything they have in a final attempt to make the human change for the better, from Sans's desperation, and trust in them to do good.

Phase 3.5: After the results of each of the Phase 3's, all of the Sanses would regroup with one another as a part of their Trios. In Murder Time Trio, the three Sanses agree that they are currently at a disadvantage against the human in each of their weakened, attacked states. So they decide to do something that would truly change the course of this battle. They would decide to fuse together, utilizing the chaos of the space to merge their bodies together, creating the one known as Satsujin.

As for Karmatic Time Trio, the now quintet; Last Breath, KiaB, Betrayer, Ainavol, and AGEM (who decided to join Karmatic Time Trio as being an ally of Ainavol) square up for their next phase of the battle. With Last Breath entering their third phase, alongside KiaB, and Betrayer, with Ainavol and AGEM in their second phases.

Now for Hope Time Trio, CotV continues their continuous support, with Hardmode having recently joined to the Hope Time Trio reshaping the Trio replacing TitR, with Distrust of course also squaring up for their last stand.

Phase 4: This is where the escalation begins, with Satsujin providing massive offense to the battlefield, all of Karmatic Time Trio locking the hell in, with Hardmode Sans alive again, Distrust Sans giving everything they have in one final attempt, and Call of the Void Sans acting as the mastermind of at least their own Trio, Hope.

Throughout this phase would be a mix of the 3 previous strategies mixed together: They’d all start together initially, but frequently one Trio has an independent turn, with single members/Sanses (or multiple) soloing against the humans themselves.

Halfway through the fight Hardmode Sans would begin melting from the Determination in their soul (alongside KiaB Sans having injected stolen Determination into themselves), so they start pushing the limits of how far they can use attacks knowing that they’ll die either way. Meanwhile, Distrust Sans is still firing their own attacks reluctantly, still hoping despite everything they’ve seen the humans do in this fight alone.

Another thing that happens at the halfway mark is Ainavol and AGEM having noticed the capabilities of fusion from Satsujin, realizing their souls are so similar decide to do it themselves: They decide to merge their bodies into one, they decide to fuse together, into the one known as AinavolAGEM. AinavolAGEM would provide significant offense just like Satsujin is, but less, as they also have to provide support for the rest of the Karmatic Time Trio.

Phase 4.5: As the fight is beginning to arrive at a close, AinavolAGEM in an act of sacrifice decides to throw themselves at the human, using the combined energy of both Ainavol and AGEM in an act of self destruction, although destroying themselves. This would unfortunately not work as the human would survive with only a fraction of their HP left, but survive they did nonetheless.

For the rest of Karmatic Time Trio, KiaB’s Determination melting would result in their death at the end of the phase, with Last Breath being finally hit a second time by the human, perishing, as well as Betrayer taking a second hit, perishing as well. And of course, AinavolAGEM’s self destruction leaves them dead as well. Now the four Sans’s souls lie in the dust from what was once the Karmatic Time Trio.

Now with Murder Time Trio, or really just Satsujin, they get hit by the human, but with the sheer power of the three fused Sanses, they’re able to tank it and stay alive.

Finally, Hope Time Trio: Hardmode Sans knowing that they will soon die, having already pushed themselves to the limits having known this information already decide to use their dying moments as an act of sacrifice. Hardmode Sans would jump in front of Distrust Sans who was about to be attacked by the human, with Hardmode Sans taking it instead, finally collapsing after knowing they were on the verge of death for so long. As for CotV? They take Hardmode’s soul, use the DT Extractor on it to take back its Determination, and then apply it to themselves. Now leaving Hope Time Trio as only a duo lead by CotV Sans (phase 3), and Distrust Sans (unofficial phase 5).

Phase 5: Before the fight is able to continue, the persisting wills of the four judges left from Karmatic Time Trio; Last Breath Sans, KiaB Sans, Betrayer Sans, and AinavolAGEM, are able to have each other’s souls combine with one another into one soul coming to life, the one, the only, Kyuuseishu.

Now as the fight actually starts, Satsujin and Kyuuseishu, being the ultimatum fusions of their respective Trios, would pair up to provide an even deadly offense towards the human.

But as for Hope Time Trio, CotV Sans would utilize the Determination as did TitR Sans and Hardmode: going absolutely all out. But as did TitR and Hardmode, they would melt, and they would knot this. So there’s no point of holding back now, especially after two people have already died.

As for Distrust, the Annoying Dog would show up, and use Sans’s Special Attack themselves. The Annoying Dog may even show up with the Ancient Artifact and use it (idk what this would do, don’t ask me).

Despite all of the efforts, all of the desperation, it would all be for naught, as the human would continue their persistence, would continue their Determination to finish the fight, and to finish their quest at total annihilation.

The Amalgamates would also suddenly show up halfway through this phase due to the fight being taken in the True Lab. They would really only provide support to the attacks, but are still there regardless.

Phase 5.5: The human would make yet another set of attacks, with Satsujin tanking it, but would start to melt from the power of the fusion being too much to handle after enough time. Kyuuseishu would also get hit, of course, ending up with three attack marks, although this matters not too much as they’re able to live through it anyways. But it would be at this time that Kyuuseishu would realize their true capability, the capability to utilize the rifts for themselves and would use this power to summon in Descedent Society Sans, as well as Hardmode Sans once more as their allies.

Now it’s the time you’ve all been waiting for: Hope Time Trio. Unfortunately, even when given their second last chance, Distrust would fail, and the Annoying Dog would peace out, and CotV would also be nearly fully melted, so they decide upon one final plan.

CotV seeing what the main gimmick of this entire battle has been so far, fusing power with one another to become superbly stronger, they decide to do the same for their group. They would activate the DT Extractor one last time, using it and Gaster’s help to reform the souls of TitR and Hardmode, and absorb them into the DT Extractor, alongside Distrust and CotV’s souls. As the DT Extractor would activate, the 4 souls would begin morphing on top of each other, fueled by the Determination. The DT Extractor would burst open, revealing a figure standing upon the destruction. A figure known as Shinjiru. Shinjiru, unlike the prior phases of Hope Time Trio, no longer hopes that the human can change. After being pushed to the edge enough times, now all they ‘hope’ for is the hope’s death.

Now the fight would transform into a battle of the fusions against the human, a Fusion Time Trio if you so please. The Amalgamates would also join in on this trend, with all of them being in a confined space all at once, the Amalgamates themselves would fuse amongst each other into an incredibly unstable form, one that would constantly try to break itself. Despite it being temporary, while it exists it would be deemed the MEGAlgamate inhabiting all of the properties of all of the Amalgamates

Phase 6: It’s now the battle of the Fusions. With the team of Murder Time Trio’s Satsujin comprised of the souls of Dust Sans, Killer Sans, and Insanity Sans. Karmatic Time Trio’s Kyuuseishu comprised of the souls of Last Breath Sans, KiaB Sans, Betrayer Sans, and AinavolAGEM (who is itself a fusion of Ainavol and AGEM). And Hope Time Trio’s Shinjiru comprised of the souls of CotV Sans, TitR Sans, Distrust Sans, and Hardmode Sans. In addition to the MEGAlgamate, surely this team of Fusions should be able to beat the human, right?

Disregarding this question for now, halfway through the fight Kyuuseishu would utilize the rifts even further, creating a rift to the Bad Time Trio and sending the human through to it to force them to fight against, well, the Bad Time Trio. Then after the human is finished with them, Kyuuseishu sends the human through a rift to the Murder Time Trio, before then finally sending them to the Hope Time Trio, before bringing them back to the Fusion Time Trio.

Alas, despite all of the desperation, all of the escalation, and all of the Fusions, the human would emerge victorious as always. All of the fusion, Satsujin, Kyuuseishu, Shinjiru, and even the MEGAlgamate would have melted to near death. And I guess Kyuuseishu’s allies also die before any of the Fusions, but we don’t really care about them at this point, do we?

Phase 6.5: In the Fusion Time Trio’s final moments, Shinjiru through CotV realizes that why only have Fusions amongst their own groups? Why not fuse the Fusions as well? So with this idea, as the Fusions including the MEGAlgamate would finish melting to death, the chaos of the space, the wills of the Fusions, a crap town of Determination, and whatever the hell all collide their effects onto the 4 Fusion’s souls, merging them into one last soul.

This soul being the inhibitor of the one known as Tsunagari (or Kyuushinsujiruki) who has the power of 12 different Sanses, the properties, of Karma, the Rifts, Determination, and Fusion, as well as all of the Almalgamates; will they have what it takes to finally defeat the human?

Phase 7: The answer to whether or not Tsunagari can defeat the human is: yes. Yes they can. They just can, do I really need to explain why?
