Search For the Medal
Even though he lost his medal to Xibalba, he was still nearly impossible to injure. Despite this, he still desired the medal in order to become completely invulnerable again. Therefore, he was ready for a full scale invasion on the town San Angel, from which the hero Joaquín and protagonist Manolo were from, when he discovered that Joaquín was the current owner of the medal. He punched Joaquín over to the town graveyard, shocking everyone.
He launched his bandits on to the town, where they ravage and pillage. Manolo's father, Carlos, tries to hold them off, only to be killed by Chakal. He then continued his quest for the medal.
Chakal's Last Stand
Unbeknowest to him, Manolo had just gained the favor of the three gods; La Muerte, Candlemaker, and even Xibalba. The hero returned to life with an army of his lost relatives, and quickly defeated the bandits. Now it was only Chakal, who faced off against Manolo and Joaquín.
After a long battle, Chakal took Maria, and climbed up a bell tower. Manolo, along with Maria, face off with him for the last time, knocking him off the tower.

- Chakal is considered to be much more evil, cruel, and a monster than the other antagonist, Xibalba.
- Xibalba simply wanted to govern the land of his wife because of the lonely and desolate that is his own land, and though he was willing to cheat and murder for it, Chakal was much more willing to kill, murder, and rob a whole town for a mere magical medal.
- Xibalba was truly neutral and he eventually redeemed himself in the end by helping Manolo defeat Chakal, and compared to the bandit king Chakal, who was a truly cruel and truly ruthless killer and murderer, Xibalba was simply an enstranged husband and lover.
