Malachai "Kai" Parker was a siphoner-vampire hybrid that first appeared in the third episode of the sixth season of The Vampire Diaries as well as the main antagonist. He was the son of Joshua Parker and his unnamed wife, the twin brother of Josette, and the older brother of Olivia, Lucas, Joey, and three other unnamed siblings.
Definition:
Kai was a charmingly unstable newcomer with the unsettling ability to seem normal as the situation demands. He can be both playful and obsessive with a mix of adolescent angst, likely stemming from the fact that he was referred to as an "abomination" due to his unique magical ability. He was shown to be a psychopath originally, after merging with Luke and gaining emotions, something he himself later confessed to. This was demonstrated when he killed four of his siblings with no remorse, for no apparent reason. He also called his brother ungrateful for fighting back during his murder. Furthermore, while killing his little sister with her own magic, he commented that the irony is funny, or sad, and that he gets those emotions confused, further demonstrating his lack of ability to feel remorse. He had also stated to be perfectly happy with who he was, even finding the idea of someone changing him funny.
He appears to enjoy killing people, as he has done so when other methods could easily have been used to escape the situation. He had also used the threat of murder to manipulate people into doing what he wants.
Kai helps to bring Bonnie back
After the merge with Luke, Kai had absorbed some of his personality and had changed. He was far less evil then he as before and even shows signs of genuine emotion, such as feeling bad/guilty for killing Luke and his other siblings. He also showed selflessness, which could be clearly seen in , when he was "half-dead" and yet agreed to help Jeremy to go back in the Prison World after being heavily injured from their encounter with Liv, knowing that his magic could overwhelm him and kill him in the process.
In , when tried to kill him, despite the fact he changed and gained some empathy towards others, he didn't try to defend himself; he simply teleported away.
Despite the fact that he was no longer the evil psychopath he once was, Bonnie, nor his coven forgave him for his actions as they believed magic couldn't completely alter another's personality. Knowing this and feeling rejected, as well as finding out that the Ascendant was destroyed (to try and prevent him from escaping) and that Jo's children (twins) could take away his leadership of the coven, he became enraged and his old personality quickly resurfaced; as in his own words, he believed that if everyone thought he was incapable of redemption, he may as well prove them right. Kai, who was already unstable to begin with, became emotionally unbalanced, cruel, sadistic, ruthless and vengeful In , he stabbed his twin sister, Josette at her wedding multiple times in the lower back, killing his sister and (apparently) the twins, because he did not want any competition in the future. In , after he was given Lily's blood (off-screen) he killed himself to wipe out his entire coven, as revenge for trying to permanently trap him in Lillian Salvatore's Prison World. Also, instead of killing Bonnie when he had the chance, he linked Elena's slumber with Bonnie's life, until the day the latter dies, as he believed she 'betrayed' him for being left in the prison world and told her it was "all your fault".

As revealed in , Kai had demonstrated that he possessed the ability to absorb a witch's power and use it as his own. This can kill said witch if Kai were to drain all of the witch's power for his needs. Aside from this ability, Kai has no other magical powers of his own, and can only practice magic by stealing the magical power of others. In , Kai absorbed the power of the Traveler's anti-magic spell on Mystic Falls, showing he can absorb power from active spells as well.
Despite having no magical power of his own, he does have the tendency to simply appear out of nowhere when he's being talked about. An example would be when Damon suggested to Bonnie to steal the Ascendant and leave without him, and Kai just appearing in the hallway. Another example would be in , when Bonnie attacks him with magic, and runs out to Damon's car, only for Kai to appear in the backseat.
He also demonstrated 's ability to turn invisible during his confrontation with Damon and Elena but only when he absorbed another witch's power.
Despite having no magical power of his own, he appears to have paid attention during his coven's teachings, as he was quickly able to use his powers to cast spells, showing that he has the knowledge required.
In addition to having the ability to siphon magic, Kai can sense magic in others, but this power was limited to being close enough to touch the person he intends on sensing the power on.
However, the little time he had spent practicing magic has caused him to not be able to focus his abilities very well. It took him a few tries before he could get spells to do what they were supposed to do, however, after that he is capable of easily using them.
Malachai had the typical weaknesses of a siphoner-witch. After dying and completing his transition, he had the typical weakness of a siphoner-witch non-Original vampire hybrid.
