Time Travel Is Bullshit!
Just as Kakara grabbed Dandeer, a strange sound, almost like whirring but fundamentally off in some way, rang out, a strange harmony with two other, identical sounds playing out. "What is that?" Yammar asked, even as he raised an arm to blast Kakara if she removed herself from Dandeer, either to try and heal her comrades or to maneuver around him.
A trio of pods appeared, and the doors burst open before they'd landed. The first two automatically fired jets to cushion their fall, but the third didn't, landing with a crash that caused obvious damage, though Kakara couldn't gauge what effect that might have on it's ability to return to their origin point. From each pod emerged... herself? No, these other Kakaras were at least a year older, maybe even two or three. It must have been a Future Trunks situation. Though, with three different versions of her, it was likely quite a bit more complicated. She could practically hear the Kai of Time screaming her head off.
The leftmost and central ones were nearly identical, if somewhat sickly-looking, but the one on the right looked... off. She was cold, and hard, and... there was something in her eyes as they landed on Dandeer that frightened Kakara on an instinctual level, and disturbed her because it was essentially her own face making that expression. She realized she hadn't looked in a mirror since she'd permanently regained the memory of what Dandeer had done to her fellow Sorcerers. That was what completed the circuit in her mind.
In the instant where the other two time travelers were surprised by their compatriots, the third Kakara simply pulled up a hand, extended a finger at Dandeer and fired- was that the Death Beam?! Kakara (she'd need to differentiate the four of them in her thoughts somehow) did something she was certain she'd regret later, and threw Dandeer to Yammar, while throwing up a shield with her own KI. Since the attack was meant to core someone whose Powerlevel was less than 1% of Kakara Prime's, the attack sputtered and died without making any headway.
"Huh. I'd forgotten how stubborn I was about that whole 'never kill anyone' thing." The attempted murderer spoke for the first time, a sort of dull annoyance at her attempt on another's life being thwarted radiating from her QI. Prime was curious at how the other 3 Kakaras didn't seem to have any noticeable Powerlevel advantage on her. If anything, the other two were weaker than Prime and the Murderer. What exactly happened there? Sure they couldn't unlock new transformations without popping the wards, but it seemed odd that they'd grown any weaker.
"The hell are you doing?!" The central Kakara demanded, as what seemed to be strings of QI were spun off of her aura. The leftmost merely got into a more advanced Tien Style stance than Kakara herself had ever used.
"Most of our problems stem from Dandeer. Killing her is the most practical solution." Murderer remarked, unruffled. "Though I'll admit to personal reasons too." A glimmer of madness entered Murderer's eyes, and was extinguished just as quickly, visibly unnerving all other versions of her. Meanwhile, Yammar was moving to the far end of the hall with Dandeer. Prime was unconcerned about that. The time-travelers were blocking the exit to the hall, and Murderer presumably would rather blow up the entrance than let Dandeer escape.
"The smart thing and the right thing aren't always the same thing." Prime muttered.
"You know, Dazarel's been on Dandeer's side. Should have killed him too, which I will as soon as I'm done here. This whole mess could have been avoided if you'd just let Jaffur kill her." Murderer stated, before raising her other hand to fling a Death Wave at Strings and the other Kakara.
Strings moved out of the way, her flight a little sloppy, as if her body wasn't moving the way she expected, but the silent Kakara didn't move. The reason became obvious when the world's coloration in a ten meter radius briefly inverted, and the section of the Death Wave that fell into that range stopped, and then was flung back at Murderer. Murderer's surprised expression lasted only an instant, before she calmly canceled out the blast with a focused one of her own, and did the same with the blasts Yammar, Prime, and Strings had taken the opportunity to launch at her.
"Shouldn't have sent an unconcentrated blast at me like that. Between it basically being my own QI and that, you were practically giving it to me." Thief smirked.
The realization hit the other three at the same time. """The Genki Dama?"""
"...You know, I really should've expected you all to get that, being me." Thief admitted bashfully.
"I'll have to look into that later, but for now, I don't think that's going to help you survive getting punched in the face until your face stops looking like a face." Murderer threatened calmly.
"Well, that is something Frieza Stylists excel at. Guessing you were expecting taking Dandeer down a peg to cancel out the stigma there?" Strings asked.
"Giving a damn about what people thought instead of just ripping Dandeer's tail off and dumping her in a cell while she was incapacitated was a a mistake. One I do not intend to repeat." Murderer explained.
"'Better to ask forgiveness than permission' huh? I can see where you got that idea." Thief admitted.
"Can we focus on keeping a future version of me from killing Dandeer please?" Prime asked.
"Yeah, sorry, I'm just surprised." Strings said, firing a stream of blasts that Murderer was still flinging aside without any qualm, even with Prime and Thief joining in. "I was actually aiming for right after Jaffur was Unsealed, but I guess that's just what happens when you don't test the time machine before you use it."
"Uh, hey guys, how long do you suppose it's gonna be before she does something nutty?" Theief asked. "I mean she is one of us and she's in a bad position so-" her speech screeched to a halt as Murderer dived into the ground.
"What's she planning? I mean, it's not like she can hit any of us without warning from down there. Stone doesn't muffle our kind of QI from this distance." Prime's eyes widened as Murderer went past the three of them. "She's going for Dandeer!" She announced to the others, just in case Yammar could hear, as she flew over to Dandeer's body, and while Strings fired Heal Beams at the Senzus, Dandelor, and Jaffur as she passed, Thief did her best to keep up with Prime. Her slightly lower Powerlevel, maybe 10% lower, hindered her immensely even over the short distance to where Yammar was guarding the prone Sorceress.
Yammar, as luck would have it, had hears her, and he picked Dandeer up and blasted the ground beneath them just as Murderer neared their location. The QI signature banked sharply, before emerging between the two pairs. "I know that we're all persistent morons, so let me be clear. The Misfits died because of her in my timeline, because of my high-and-mighty pacifism. So I won't stop until she's dead." Murderer stated bluntly, and blasted Yammar in the face while Thief and Prime blanched in shock at that declaration, while he was grabbing at his ruined eyes, Murderer was aiming an attack at Dandeer. Reacting on instinct, Prime used Instant Transmission to interpose herself and the beam, but this time it was Death Cannon, which did break through Prime's guard and leave her a bloody mess. As she fell backwards, she saw Murderer punch Thief in the gut hard enough to make her vomit blood.
The last thing Prime saw was Murderer destroying a wave of QI strings Strings had sent at her from all directions, as Jaffur, battered as he was, attacked her.

Future Kakara shook off the Vision. "Okay, time travel's a bad idea, got it. Time for Plan B."
AN: The basic difference between these three time travelers is that Thief came back from two years in the future, Strings came back from one year in the future, and Murderer came back from three years in the future. The amount of time they spent without a body varied as well, but that's the big thing that changed between the three timelines. The Thief spent less time as a Shade than Strings, and so had more time to practice stealing people's QI blasts and sending them back. Strings was forced to spend most of her year as a Shade before they got her body back in a raid, so she spent most of her time learning the string-thing so she could hard-counter Dandeer's mind control. Doesn't matter whose side you're on if you're body does what Kakara says anyway.
Murderer got her body back near the end of two years, and by that point some seriously bad shit happened in her timeline, resulting in her Hopeful Trait going poof, which made her Protector Trait mutate into something a lot more... Absolute Utilitarian. The 'kill someone to save ten people' sort of Utilitarian. Hence the Frieza Style and decided lack of reaction to the idea of killing Dandeer, since Dandeer was somewhat responsible for the bad things happening. Murderer has placed most of the blame on Dandeer and herself rather than the ones who actually pushed the button, which also contributes to her lack of care for either her past self (who she intended to pull a Kill And Replace on since Past Kakara has already committed all the 'crimes' that led to that series of events) or her other selves, who she'd probably just leave alone if they let her thing, but clearly retained her past self's values.
