—Jack threatening to kill Gilbert to manipulate Oswald

Jack Vessalius (ジャック ベザリウス, Jakku Bezariusu; sometimes romanized as Jack Bezarius) was previously believed to have been the hero of the Tragedy of Sablier, however recently it has been revealed that this was a farce. Rather than acting as the hero, Jack was the Tragedy's instigator, having done so all in order to plunge the world into the Abyss to allow his and Lacie's souls to reunite (despite the fact that Lacie's soul had been destroyed by the power of the Abyss).

Jack is the creator of the current social system, forming Pandora and the Four Great Dukedoms. In addition, he invented the Carcere, thereby making him the father of Legal Contracts. Despite this, he retains an Illegal Contract with the Chain, Oz the B-Rabbit, having done so for more than 100 years.

After the Baskerville Clan fell into the Abyss with Sablier, and Jack had killed the only one with knowledge of his treachery, Oswald, he pinned the entire Tragedy on the Baskervilles and tarnished the Nightray Dukedom's reputation by spreading false rumors. Jack soon revealed his intentions to Arthur Barma, and manipulated him into chronicling faking the events of the Tragedy to portray Jack as the hero. He had also manipulated Arthur and four mages into creating the Sealing Stones, using Oswald's body, in order to permanently bind Oswald's soul. In doing this, this helped Jack to "disappear" from the public's eye.

As Jack's soul had been rejected by the Abyss and removed from The Rule of 100 Cycles, he is forever cursed to have his body rewind in age, with each reversal tearing his soul apart. Today, Jack is still alive, but his soul exists in minute qualities, allowing Oz to be the dominant position in Jack's body. Jack is still able to take over his body for brief periods, recently severing the Chains around the world (in order to cause another Tragedy) during one of these periods of time.

As a result of Oswald telling Oz his wish, Oz was able to regained his body and limit Jack's influence of their body. Upon arriving at Sablier, Oz and Jack made a deal, which was Jack rescuing the Intention of the Abyss from the Core. Although Jack was skeptical and had no desire to do so, Oz was able to convince him what he was currently doing wasn't what Lacie really wanted. After fulfilling Oz's promise and telling the Intention the truth of what he did and why prior to the Tragedy of Sablier, the Intention forgave Jack. When the Abyss returned to its original form after the Intention's death, Jack realized his mistake and gave up his attempts to destroy the Chains. Jack offered to give the Core his body as a vessel after stating the Core really cared about Alice and the Intention so much. Jack shortly passed away later on.


Jack wears white skin-tight pants with a long green and gold coat and a white ruffled blouse. He uncannily resembles an older, adult Oz with long golden hair that is braided and reaches down to his thighs. He has long golden eyelashes and emerald eyes like Oz's, but has a different aura. He wears white gloves over his hands, and in most instances is shown with a pair of equestrian white and black boots. He has a pair of deep magenta/blue/purple earrings (the variations of watercolors makes the true color appear differently each time) that Lacie gave to him, the right one having been kept and later worn by her for the four months after their reunion, while the left was worn by Jack for the eight years since their meeting. Oswald gives Jack the right earring that Lacie had worn when he tells him of her death.

It seems that the reason that he and Oz seem so similar is because Oz's body is really Jack's that he has allowed Oz to inhabit.

Oz and Gilbert met him (a piece of his soul) when they were at Cheshire dimension. Initially he was thought to be the "hero" of 100 years ago and the one who "defeated" Glen Baskerville. Jack is alive and always has been since the tragedy, but his body does not follow the 100 year cycle and so Jack matures to his age at the time of the tragedy, then regresses to an infant. He was a child when he first met Xai Vessalius.

Jack is just like Oz, seemingly always happy and overly optimistic. He can be serious on occasion, but is usually highly active and cheerful. He appears to be kind and simple, but is actually clever and highly manipulative. Something else to note about Jack in particular is that he can give a sharp gaze that appears as if he is looking right through someone and at their true selves.

He harbors a grudge against his family because of his difficult years growing up, but hides this when he is with other people. Lacie is the only person whom he's ever confessed it to. He worships Lacie, and places her above everything else, including his life. His obsession with Lacie, especially after her death, eventually leads to the Tragedy of Sablier, the near destruction of the world and subsequently many of the events that occured years later.

In his grief, after Oz showed him bits of Lacie's memories and feelings at The Intention of the Abyss's request, he realized that Lacie was not going to be coming back to their world. So he reasons that he'll just have to bring the world to her. He now seeks to 'send' this world to Lacie so she won't be lonely, completely disregarding the fact that Glen explained that she was destroyed and does not exist anymore. His soul is shattered during the tragedy, excluding him from the 100 year cycle, and he fears that he will eventually be wiped out of existence.

Recently, it has been revealed that Lacie is the only person that stirs emotions in him such as hate and loathing. These emotions made Jack feel alive, and he is now convinced that the only way he can "live" is to be near her side.

It's possible that Jack is something of a psychopath, considering he appears to have no true feelings for other people, despite the fact that he is very good at pretending he does. Several other people have described Jack as seeming empty and like water. Another thing that supports this is the fact that Jack claimed he was "in love" with Lacie, but it seems that his love for her is based on the fact that she taught him to make his life matter to himself, and how he only cares that she died because of his lack of emotions now.

Abilities and Powers

Jack is able to possess and fully control Oz's body and B-Rabbit's power freely. This is because Oz has current possession over his body and was Jack's former chain.

  • Jack is an exceptional sword fighter, though he is weaker than Glen.
  • Jack is very good at lying and manipulating others for his own intentions. He managed to convince Alice (Intention) to forget about Oz and help him with his plan. He also used Miranda and Vincent to open the Door to the Abyss so he could form a contract with the chain strong enough to destroy the world: Oz the B-Rabbit, which The Intention of the Abyss created for the task.
  • Jack may have become intimately involved with members of high class families through years as a valet in order to gain higher status and enter the Vessalius dukedom. (assumed)
  • Jack is also able to summon the chains supporting the world with Oz's power.
  • Because Jack formed a contract with Oz the B-Rabbit, he is able to use his destructive power for whatever he wants. However, it appears that Jack is the only contractor to use his chain's power against their will.
  • While in the Cheshire's Domain, Jack was able to transport Oz to another location closer to Alice.
  • He is able to play a few instuments, some highly unusual, and he must have played 'Lacie' for Alice or her sister Alice (Intention) on the piano in their room.

  • He is also good at making music boxes, and made the pocketwatch that Oz carried around for most of the series.


To Oz

  • "Be careful. You're being watched by the Intention of the Abyss."
  • "Humans...are weak, aren't they? Me, and Glen, too."
  • "Here I've shown you all my memories...and yet it seems you still missed the point... No, rather it's that... You're refusing to see the truth..."
  • "I'll show you.. Just how wrong that statement is...This body... Does not belong to Oz Vessalius...nothing can belong to someone like you. You can achieve nothing, you can't become can't, you just can't!"
  • "You are nothing, you are nothingness...because you destroy everything!"

​To Oswald/Glen

  • "So, Glen, won't you lower that sword... before I kill your cute little servant?"
  • "What’s wrong Glen? Why don’t you hurry up and drop that sword? I really don’t want to.... hurt you like this."

To Alice

  • "No that's just a big misunderstanding, Alice. B-Rabbit is MY chain! The one who should leave this body... and disappear you, Alice."

To Intention of the Abyss


​To himself

  • "Whenever it snows... I am reminded of those days....the day that you found me....and the day that I finally found you...-and I lost you again, Lacie and this time... Its for good"
  • "This world that Lacie loved so much...I will let it sink into the Abyss! So that Lacie who has become one with the Abyss...won't have to be lonely ever again."
  • "I saved the two boys from being inflicted by meaningless violence. The reason why was simple. Vincent had the same red eyes as Lacie. When I brought them back to the estate, and asked them about their situation, I realized something. The circumstances of these two corresponded with the characteristics of the Baskervilles that Levi told me about. I informed Glen about that, and the next day, the Baskervilles came and took those two to Glen’s estate."
  • "To me... This world is like a dark night that swallows everything. But since you came into my life... And you were so kind to find me... I don't need friends or status anymore. I only need... To have you by my side! Lacie!


(*) - Denotes that the character did not appear physically, but as a part of another character's memories.


  • Apart from Jury and her fellow Jurors, Jack is the oldest character in Pandora Hearts; having lived for nearly 1 1/2 centuries. Furthermore, Jack is the only human character to have achieved his unnatural age without the use of time travel through the Abyss.
  • Whenever appearing in omakes, Jack is almost always seen with a mikan (a type of citrus), which acts as his character symbol. Interestingly enough, it's thought that the use of a mikan is meant to represent Jack's overall character, as both seem to have both sweet and sour qualities about them.
  • Continuing with the tradition of the inspiration of the Pandora Hearts universe from elements of the Alice in Wonderland universe, Jack's character is likely based off of the Knave of Hearts from Lewis Carroll's Alice's Adventures in Wonderland, given the two characters' dishonest personas.
    • Additionally, a knave can also be referred to as a "Jack", possible hinting at the inspiration behind Jack's name.
    • To further this fact, Jack was closely connected to the Barma Dukedom more than 100 years ago through Miranda and Arthur, both of whom are meant to represent the characters of The Queen of Hearts and The King of Hearts respectively - solidifying his ties to the "Hearts Suit" theme of characters.
  • Another reference to Alice's Adventures in Wonderland lies with Jack's first appearance to Oz after his return from the Abyss. In Alice's Adventures in Wonderland, Alice had to pass through a tiny door which appeared to her behind a curtain in order to get to Wonderland itself for the first time. Similarly, Jack appeared behind a veiled archway to Oz upon their first reunion and urged him to continue searching for Alice's lost memories - thereby "opening the door" to this new Abyss-driven world heavily mirroring Wonderland.
