Xibalba

"How about a little wager?"

- Xibalba to La Muerte.

Xibalba is the secondary antagonist (later anti-hero) of the 2014 computer-animated film by 20th Century Fox, The Book of Life. He is the dark, ruthless, and manipulative ruler of the Land of the Forgotten, who enters the plot upon making a wager with his estranged wife and fellow deity, La Muerte.

He was voiced by the famous legendary actor, Ron Perlman, who is best known for playing The Lich, Dieter Reinhardt, Nino, Warhok, Fire Lord Sozin, Sheriff Collie Entragian, the Stabbington Brothers, Bai, and numerous incarnations of Deathstroke (most notably Slade).

Personality
Contrasting the lively colored and adorned La Muerte, Xibalba carries a grim and darker appearance befitting his role as the ruler of the Land of the Forgotten. True to the Day of the Dead iconography, Xibalba resembles a skeleton with wings and a crown. This connects with the origin of his name as the underworld of K'iche Maya mythology, roughly translated as "the land of fear". It also highlights his more blasphemous and sinister qualities, such as his determination to win his wager between himself and La Muerte through underhanded and manipulative methods. Xibalba understands humans as petty, assuming that María would be won over by Joaquín's use of the Medal. One condition of the wager noted that he loved to mess with the lives of mortals, as seen when he blows out the memorial candles and attempts to take the life of an old man. He also does not take lightly to anyone who challenges him, as seen with Manolo's angry and acrimonious declaration that he will expose him to La Muerte. This prompts Xibalba to respond that no one who talks to him in such a manner survives.

Nevertheless, Xibalba sincerely loves his wife and seeks to reconcile with her. Despite this, he still takes advantage of her willingness to engage in wagers in order to gain attempts at power. However, in the end, he manages to put these negative qualities aside, so that he can be with her once again. By the present day, their relationship is still shown in a more positive light, suggesting that he has redeemed himself once and for all.

Role in the film
Xibalba is established as the tyrannical ruler of The Land of the Forgotten, a duty he has grown to hate due to the dreary conditions, especially contrasted with the festive nature of his former lover's domain, The Land of the Remembered. Prior to the events of the film, Xibalba had made a bet wherein he cheated, resulting in not only his ruling state, but also his estranged relationship with La Muerte, with whom he seeks to reconcile.

Determined to escape his role, Xibalba proposes another wager with La Muerte, this time concerning a budding love triangle between two friends, Manolo and Joaquín, and their mutual female friend, María. Xibalba bets that the latter will marry María in the future, with the condition that he shall rule The Land of the Remembered if he wins. To ensure a chance at victory, he, in the form of an old beggar, provides Joaquín with the Medal of Everlasting Life Years later, Manolo and Joaquín both unsuccessfully attempt to woo María, although Manolo, which grants its wearer functional immortality by making them unable to be harmed or killed. manages to make a heartfelt connection with her. Determined to not lose the wager, Xibalba summons a two-headed snake and sends it to bite Maria, putting her into a coma-like state, until she would conveniently reawaken once she was with Joaquín. With this, Xibalba, in the same old beggar form as before, takes advantage of Manolo's grief-stricken belief that Maria is dead to manipulate him into accepting his "help" to find María. He has the two-headed snake bite Manolo twice, which does kill him. With Manolo dead and María set to wed Joaquín to ensure the protection of their village, Xibalba declares a victory on the wager. When Manolo goes forth to find La Muerte, so he may find María, Xibalba is sitting in her stead, where he confesses to Manolo about the wager he made with La Muerte and the first bite that only put Maria into a deep sleep before she was awakened by Joaquin (with the usage of the Medal). It was then Manolo realized that Xibalba cheated on the wager and gets very furious at him for it.

Manolo angrily swears to head over to The Land of the Forgotten to find La Muerte and expose Xibalba to her for his cheating, but Xibalba brushes this off as he heads off to oversee Maria and Joaquin's wedding. In the meantime, the notorious bandit Chakal, who previously had the Medal of Everlasting Life until Xibalba stole it back, is alerted to its presence on Joaquín and declares that his forces will take the village on the Day of the Dead.

Despite the arduous journey, Manolo, along with his deceased mother Carmen and grandfather Louis, reach The Land of the Forgotten and approach La Muerte before telling her about Xibalba's cheating. Xibalba is summoned and confronted by La Muerte for his actions, and he inadvertently slips that he gave Joaquin the Medal of Everlasting Life. As a result, Xibalba receives two slaps on the face (one from La Muerte, and the other from Carmen) as punishment. Upset and humiliated, Xibalba stubbornly refuses to back down until Manolo offers him a new wager: Xibalba will give him a task that Manolo must face, and if Manolo wins, Xibalba will grant him life to get back to the land of the living; but if Xilbalba wins, he will get to rule both the Lands of the Remembered and Forgotten, and Manolo will be forgotten forever. Finding this to be extremely funny and amusing, Xibalba accepts and takes advantage of Manolo's wager by forcing Manolo to fight all of the deceased bulls that have being slained by the Sanchez family for years, believing that it to be his worst fear. The stakes are raised when the bulls form together into a giant demonic bull to finish off Manolo. However, Manolo reveals that his true worst fear was being himself, which he overcomes when he sings the giant demonic bull into a peaceful state while giving out his apologies for his family's transgressions. The demonic bull accepts Manolo's apology and dissipates into a peaceful and nonviolent afterlife, allowing Manolo to win the wager.

Seeing Manolo triumph in the wager, Xibalba is completely speechless and initially upset over his defeat, but decides to accept it and grants Manolo a return to life as promised, so that he may help defeat Chakal and be reunited with María. Seeing both the living and deceasad reunited to take down Chakal and his forces, Xibalba abandons his cheating ways and successfully reconciles with La Muerte.

During the frame story, a museum tour guide named Mary Beth guides a group of children to the eponymous Book of Life to tell them the story along with an elderly security guard. In the end of the film, Mary Beth and the security guard are eventually revealed to be La Muerte and Xibalba in disguises, and as the children leave in their bus, La Muerte and Xibalba show out their true forms to share a tender moment with each other.
