Kai Parker was born in 1972, Portland, Oragon, along side his twin sister Josette Parker. To the Gemini Witch Coven. Kai was discovered to be a Siphoner more than likely before he was even born. Something that was often treated terribly by witches. As these others witches had seen Siphoner’s as 'abominations'. This lead to Kai's parents mistreating him from the moment they found out what he had been. Often ignoring him, or preventing him from touching others, or others touching him. Since the time he was four years old, or when ever his siphoning powers had begun to manifest, he had been 'needing a fix' to absorb magic. The absence of which had caused him to feel like he was on fire. So, as he grew up, feeling unwanted, feeling wrong, and feeling disgusting. His parents were plotting to screw him out of the one thing he was promised, the one solitude he did have to look forward to. Merging with his twin sister the supposed 'Glinda' of witches, as far as Kai had seen, with the way Josette was treated in comparison to himself.
Eventually all the mistreatment and need for a fix had driven Kai to become angered and sociopathic, as abused children tend to become given the stipulations. Which fit perfectly, Kai is a product of child abuse. Upon finding out what his parents had planned to do, and apparently having been causing worry from his parents with his activities leading up to the moment he was supposed to merge with Josette. Joshua had felt that Kai was much more powerful than Josette and so together, Josette, Joshua, and the rest of the Gemini coven plotted against Kai. Thus Lucas and Olivia were born. Four years later, Kai would, upon figuring out the reason for their births, try and murder them. But he only managed to murder four of his other siblings before being mislead by Josette into believing she would finally merge with him. But this had turned out to be a lie. Once Josette had lead him to the trap, and the two had begun the merging ritual, the rest of the Gemini Coven had started casting another spell. Kai also in this moment found out that Josette had hidden her magic somewhere. Kai is then, moments after, sent to a Prison World, by his own family/coven, where he would spend the next eighteen years in solitude. Not even attempts to kill himself would free him from. He was forever trapped in the year of 1994. Or so it seemed.
Eighteen years after his coven betrays him. Bonnie and Damon appear in his prison world. Kai watches them for several months as they fuck off for a while doing stupid shit and god knows what, arguing mostly. Who honestly fucking cares. Anyway, Kai finally revealed his presence to the two of them one day and then starts attacking Damon, then he fucks with the two for a couple of days. Bonnie finds a news paper and goes " OMG, he murdered four people of his family. Let's do the exact same thing his family did to him, and nothing bad will happen. HAHAHAHH!" So she fucks off with Damon and murders Kai. It's fine, not like he hasn't died plenty of times already in that prison. Later, in a cave, just as the pair are about to fuck off, Kai comes back and shoots Bonnie in the diaphragm and send her flying out of the moonlight. Damon tries to man up for a minute and he and Kai have a dick measuring contest, who cares. Bonnie eventually sends Damon back to the real world, alone. Buh bye.
Anyway, Kai, having now gotten off to a bad foot with Bonnie, officially. Starts trying to fix the artifact that will help them both get out. Bonnie, being a genius decides " Nah, I don't want to do that. Because how dare you." Or some piddly ass moralistic petty reasoning. Bonnie then stabs Kai in the neck with a fork, takes the artifact and runs off to a nearby hospital as Kai seems to bleed to death. Because that's never happened before. Anyway, Kai catches up to her and reveals he has the last piece to the once broken artifact and is like " Yo what up mama, let me show you what you forgot. I'm smart too. Sometimes." Then Bonnie starts freaking out again, because apparently that's what she's best at,...being JUST angry at Kai, a person she's just met, and doesn't know, for doing bad things. Because she DOESN'T know him, she has every right to be a bit of a bitch.
Everyone else she does know can murder people all they want. But she'd be damned if she let Kai do that. Nuh uh, not on her watch. Anyway, Kai catches her in Damon's car that he drove all the way to 1994 in order to fuck with Damon and Bonnie earlier, and he strangles her there, because why wouldn't he at this point, honestly. They aren't friends. She doesn't even GO here. Anyway, after kidnapping her and stuffing her in the trunk of the car, for safety reasons one must assume, since Bonnie is almost as insane as Kai is, clearly. He probably wants to avoid being stabbed in the neck again. Probably, who knows, MAYBE he enjoyed it. Maybe he's a masochist. You don't know! Anyway, they have thanks giving. It's fun. Bonnie is moody, because how dare she not get what she wants. How dare Kai want freedom, even if it is at the cost of murdering his entire coven. No one but her has any right to do wrong, unless she likes you. Then you can do all the wrong you want. She'll be like "Aight, you do you, Stefan." So, anyway, Eventually she makes a deal with Kai, who lies to her about letting her go her own separate way. Because of course he fucking lied to her. And she's about to spend the next few months or so of her life figuring out why.
Anyway, Kai stabs Bonnie in the gut, because all he needs is her blood and magic. Which the hunting knife he used to stab her has magic in. Because that's where Josette hid her own magic just before fucking Kai over and sending him to that prison world to begin with. He then had all of the things he needed to perform the ritual, without Bonnie. Which I mean, is literally her own fucking fault. Had she of just let him out the first time and ignored him. She wouldn't have had to be shot with an arrow, drugged, kidnapped, stabbed, abandoned and left to rot in Kai's Prison world for months. But instead, genius that she is, she basically in more or less eloquent terms, deserved everything she fucking got. Change my mind. You won't. Soooo Anyway, Kai is freed, he does whatever Kai wants to do murders a few people, finds his siblings. Pisses them off by trying to kill Olivia. Then he changes his mind and offers to merge with Josette and...leave them alone. Which is growth, motherfuckers. Because that is basically what he does. Well, once he merges with....Lucas. Instead of Josette. Lucas had offered himself up, to protect Josette. The other was pretty confident that they could possibly, maybe beat Kai in the merge. And Josette had also seemed to hope for such a thing to. However, nope. Lucas lost and merged with Kai instead.
Then he didn't murder his entire coven. But instead went about doing whatever it is that Kai generally does when he's not murdering people. Annoying them. But now he his younger brothers 'empathy' and 'emotional' range. So that's fun. He has 'grown', so it seems. Then it shows when he offers to HELP Damon, Elena, and Jeremy get Bonnie out of the prison world he left her in, because he feels bad for what he did. During the last of the attempts to try and save Bonnie however, Olivia stabs Kai and the two start kicking the shit out of each other. Because Oliva has as many brain cells as Bonnie does. Which is about two. Olivia begs for death and Kai tries to kill her, but because he is merged with Lucas, the others emotions stops Kai from going through with it. Then Kai just moves on and continues to help Jeremy with reaching Bonnie, thus stopping her from killing herself. Kai almost dies during this incident, but is saved when Damon and Elena get to him and Jeremy in time for Damon to feed Kai his blood, which heals Kai.
Life goes on, mundanely for a little while before Josette gets sick and ignored a phone call from Kai, trying to tell her he is sick. Which turns out that he just needed some magic, it's all good after that. Also Josette is pregnant with some babies of which Kai is like "Hey stupid, you're preggers, hows that for Irony." Then he fucks off to do whatever Kai does when he's not annoying or killing people. Probably enjoying his freedom and the new stuff he can toy around with in the future. Eventually however, Bonnie makes it back. Kai comes along then and tells Demon, who has just found out his mommy is alive and well in another prison world. He wants Kai to bring his mommy back and Kai is like "For a price, sure. Let me reconcile with Bonnie though." And Demons like " Sure yeah, sounds like a great Idea, let's just go do that." And they do that. Bonnie, with her two brain cells, and a bit of murderous insanity, decides to not do what's probably best for her and tells Kai he can go fuck himself for what she has done to him. Because, no one has ever felt that before, in their life. Besides Kai, who she stabbed in the chest with Pick axe, and killed him, compared to him shooting her in the chest with an crossbow bolt and then stabbing her with a knife while fucking with her.
Which one could say she did just as equal damage to him, despite his ability to revive and heal from it quicker than her. He also spent eighteen years in that prison. So if she gets to be a bit pissy about it. So does Kai... Kai decides to reveal stuff about Damon's mommy anyway. Like that she's a fucking psychopathic vampire that people in this stupid show call a 'ripper' because they are about as creative as a toddler with a marker. Messy, not too creative though. Anyway, Bonnie throws her tantrum off somewhere else away from Kai for a little while. Tries to make her point with Damon by hurting Damon the same way Kai hurt her. Which is fair, I suppose. Since she's fucking stupid and doesn't realize that her PTSD is just as valid as Kai's abuse and PTSD. So she needs to get off her fucking high horse and join the rest of the world, honestly.
Anyway, Eventually they go on the quest for Damon and Stefan's Mommy because Stefan is murdering the fuck out of people or something. Bonnie is all " Aight. I'll go. That's cool. Cool cool cool. Kai, let's hold hand." So they do that, they go to the year 1903 where Lily, Damon's mommy and her Heretic vampires are. Damon and Elena go " Nope." to it all but still want to bring Lily back so they lie to her or something, who cares. Kai and Bonnie are on a misleading mission that Bonnie suggested because she wants to fuck Kai over the way he fucked her over. Because she's still got only two brain cells, guys. Let's be real, as trash as Kai is, Bonnie becomes just as much trash in this instance as Kai times his entire fucking coven combined. Because without her petty behavior...AGaIn. The next part wouldn't have happened! Anyway, she dispatches Kai in the middle of the woods, during winter. Almost stabbing him in the heart before he vanished himself away from that.
Some time later she meets up with Damon and the plot device of conveniences. They all start the ritual to leave that prison world and just as they are about to peace out Kai screams toward them, Bonnie see's him and smirks at this. By the way, Elena and Damon are completely okay with what's happening, fully aware of it. So they are just as much to blame for what happens next as Bonnie herself is, honestly. Every last one of them is a shitty person. But this show is kind of really garbage so, let's move on- Kai is abandoned in 1903 by people he wanted to clearly be close to, maybe even befriend, after the terrible things he had done to them. BUT NOPE! He ends up finding his way to Lily's place, where the heretics remained. There he is bitten by one of the Heretics inside her house. Some time later, he manages to control the Heratics or some wacko ass shit that happens.
What is important about that moment is that he's getting out of there, 1903 that is. He's clearly no longer influenced by Lucas' empathy or emotions. But let's say that Lucas, after witnessing all the bullshittery and filtering through it was like " Nah. I'mma just let Kai fuck you all over. Peace Bitches. I'm going to get out the way." Anyway, Kai free's himself, again, and makes his way to Josette's wedding where he repeatedly stabs her in the back before revealing his presence to all and being like " Miss me?" Before killing the ceremony participants. Or well, mostly fucking them up. He also puts Elena to sleep, because hello, she and Damon ABANDONED him in a PRISON WORLD. HELLO!? Are you all idiots? He's clearly a lot smarter than these three individuals in particular, and it shows. Despite his pension for falling for traps and dumb tricks.
Anyway, he kills Josette, and Joshua is like " Kai, don't! Stop being a bad child. What's wrong with you?!" Which Kai replies with stabbing himself in the neck. Clearly, what's wrong with Kai is that he was born into a shitty family who treated him badly and got what they deserved in the end, punished for their sins. The executioner, being no one else but Kai Parker, himself. Kai then revives, wOoOW, why's that? Oh, he's a vampire witch now. It's fine. His coven is still going to die. Which, fuck them, anyway. He then gets bitten by Olivia's boyfriend Tyler, who is a werewolf. Which Bonnie later tells him and he goes " Bye Bye Bye Werewolf Blood." And then he breaks Bonnie. Damon, having had a conversation about being bitten by vampires earlier and telling Damon that Elena won't wake up as long as Bonnie is alive, arrives. Shocker. He then proceeds to save Bonnie and kill Kai, smacking Kai's head off his body, decapitating him. Which it would have been funny, if he didn't die and he was just a talking head. Wouldn't that have been funny...Anyway. Kai Dies. That's the end of that. Right? Right. Everyone gets to be idiots and continue living and doing stupid stuff. Who cares about any of it, honestly. Bonnie hooks up with Enzo, who was also doing terrible things the entire time this Kai Bullshit was going on in her life. But hey, that's ENZO, she likes ENZO.... He can do whatever terrible thing he wants to do.
Anyway, one thing leads to another and Kai is eventually like " Here, have Elena's Soul, Damon clearly doesn't want it, and I'm pretty bored with all of this. Send me back." And trades Elena's soul in order to get a get out of hell free card. Which he does, and starts bugging Damon immediately after, for some reason or another, because he's afraid of going back to hell. He could have just, fucked off, and not bothered with any of those people, since he clearly knew the entire time they couldn't help him, realistically. But whatever, its Vampire Diaries. Who gives a god damn, I guess...Logic doesn't fucking matter! Kai pisses around for a bit and then he gets captured and taken to some...magical, stronghold where conveniently enough Caroline, Josette’s baby's daddy, and Gemini Twins Next Gen are all residing. He is locked in a prison where he's like " I know what's wrong with your Gemini twins.....They are going to be great, to kill." Then everyone just, ignores him for a couple of hours. It's fine. Not like anyone has more than two brain cells in this show anyway.
SO eventually Caroline, who had the twins transferred over to her when Josette was dead, because why not. Is all "Help me with my not babies." Kai is then all " Sure, why not. Let's do this." and proceeds to explain to her that the entire building is dripping with magic and then he explodes the fucking window in her face. As she fucking deserves. Then he knocks her the fuck out. Because, why...ARE YOU. STUPID! Kai then starts running around the place, calling Baby Daddy and idiotically gloating about killing the Gemini Coven Next Gen. Picking up an axe that is perfect, for executions, and dragging it along the floor because he's still twenty two I guess and wants to be edgy, okay? So he just tralalalala's the way to whatever the fuck and gets tricked. This is the moment where you slow clap at the moronic shit that this show has exposed everyone to.
Anyway, Bonnie soon comes back into the picture and is like "I'll take that, he's actually cute. I hate him. But he cute." Then she locks him in a prison world in 2018, chains him to a chair where he can listen to a song he hates, every day, over and over again. Which I mean, congratulations Bonnie, you continually fuck it up. Along with everyone else. When you could have fixed all of this by just letting him out first, let him get his revenge and then NOT do any of the other bullshit. Because Bonnie would have had no reason to. But here we are and Kai’s back, and so is Lucas’ personality traits/Empathy, for that matter. Because I fucking said so, that’s why.
