Kai Parker

Malachai was born in Portland, Oregon in 1972 as the eldest son of Joshua Parker and twin brother of Jo. As a siphoner, he was shunned by his family, even revealing to Caroline that he wasn't allowed to touch anyone. As twins of the Gemini Coven, Kai and Jo were expected to merge. However, Joshua knew that Kai would win the merge given his powers, and knew that Kai could not lead the coven. Due to this, Joshua and his wife kept having children until another pair of twins was born: Liv and Luke. Realizing this, on May 9, 1994, he decided to kill his siblings and merge with Jo. He stabbed Jo with a hunting knife to get her out of the way as he went after their siblings, but Jo managed to cloak the twins to protect them, promising to merge with him so long as Liv and Luke could live. However, she had relinquished her magic, and the coven harnessed the power of a solar eclipse to trap him in a purgatory dimension for his crimes, which kept him trapped in a snapshot of the day that he was imprisoned.

In the Prison World, Kai tried to kill himself several times, each unsuccessful. He realized that it was part of his punishment, a safeguard by the Gemini Coven to make sure that Kai didn't end his eternal imprisonment early. 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.
