Zacharie is the game's item vendor, buying and selling items to and from The Batter. His shop is the only one in the game, and he often shows up in new areas or shortly before difficult fights.
Zacharie is initially seen wearing a toad mask, which interestingly parallels a book found in the Bismark library that talks about a Masked Man who slays a Toad King. His neck also appears to be somewhat bloated and deformed, also resembling a toad. He is later seen wearing a cat mask as a replacement for The Judge, who is put out of commission by the death of his brother Valerie. His talking sound also turns into a voiced "Meow" instead of his usual chuckle.
He has a tendency to frequently break the fourth wall, even more than The Judge, often referring to The Player directly upon speaking to them. He also refers to The Player in a sign found in Bismark's shopping mall. Zacharie seems to be optimistic, as he laughs when you talk to him. It can easily be seen that he is very greedy, before the death of Valerie, as he only seems to desire the Player's credits. After Valerie's death, he changes his mask to cheer The Judge up; which may show that he is caring. Also supporting this, he seemingly cared for Sugar, because he sadly reacted to her death. He seems to use a little bit of spanish former to Valerie's death, as he refers to The Batter [or the Player] as 'Amigo', and sometimes greets The Batter with 'Buenos dias'.
| Zacharie is the official merchant of Off - the only one, in fact. However, his business is not one of
the most flourishing ones: only heroes are willing to buy artifacts from mysterious strangers. No one really knows where all the items he offers are coming from, nor how he even got hold of them, but as a video game player, you probably couldn't care less about it, could you?

Zacharie is an item vendor, claiming himself to be "the traditional items merchant that's necessary in every video game." While the game never specifies what his actual role is, the game implies that he seems to at least know many important people that reside within the world of OFF. He is implied to own the Bismark theme park, as there is a statue of him on the roller coaster, and an Elsen guarding an office refers to him as "boss".
Zacharie knows Sugar, who requests that The Batter tell him goodbye upon her defeat. He appears saddened by her death, and there is no chuckle when he is talked to. Interestingly enough, he states that "It's probably better that way." It could be said that he was trying to be optimistic about her death, or that he was trying to keep himself calm- as that is all he says about it. This behavior suggests that they were at least friends.
Some fans note that his name sounds similar to zahar, which in many languages (eg. Romanian, Czech, Russian) means sugar, seemingly implying a connection. However, Mortis Ghost has stated that the similarity is merely a coincidence. 
Zacharie seems to know The Judge. He seemingly worries about The Judge's well-being and safety. There is also a time where he interacts with The Batter saying that he (Zacharie) is The Batter's friend, The Judge while wearing a mask made of Japhet's face, seemingly knowing The Batter's interactions with The Judge while the game progresses.
Zacharie may know The Judge since he "houses" Sugar, his might-be friend, at the basement. This may also lead to why he knows everything about The Judge and The Batter/Player's interaction.
Zacharie and The Batter are often seen interacting since he sells items to The Batter, providing him what he needs, giving him clues and is an excellent friend. While Zacharie normally would speak to the Player, he may also speak to The Batter as The Batter is being controlled. In the park, he can also be seen riding a roller coaster with Zacharie with the exception of Zacharie being a statue.
- Mortis Ghost has confirmed that Zacharie is a human.
- It's possible that Zacharie may be the Masked Man who slew the Toad King, or perhaps the story was based on or even written by him.
- The French version of the game does, in fact, confirm that Zacharie is the Masked Man who slaughtered the Toad King. The Index of the ripped-up book in the library of Zone 2 has a page named "Le roi crapaud et le marchand" which translates to "The king toad and the merchant". The significance to this and the connections to the game's actual story is not yet known.
- Zacharie may have connections with Japhet or The Queen, leading to his acquisition or creation of the Bismark theme park.
- The last line Zacharie says to the player is best understood when translated from Latin, where his final phrase, "Bis vincit, que se vincet in Victoria" translates to "He conquers twice who in the hour of conquest conquers himself."
