English version

• Johnny Rose as Leonardo "Leo" San Juan, a 14-year-old boy who is Marcella's boyfriend, and leader of the group. He has the ability to see and speak with ghosts. He is described as being brave, resourceful, honest, and noble of heart. Prior to the encountering evil forces that threaten to destroy the world, he lived in a small Mexican village with his grandmother. In the first episode, he learns that he is destined to be the hero of whom it was foretold: "The Lion will destroy the Serpent." Though he at first refuses to accept his destined role so he can live a normal life, Leo soon embraces himself as a true hero. Leo later also starts to realize Teodora Villavicencio's romantic feelings toward him.
• Oscar Cheda as Don Andrés, the ghost of an old Conquistador; he claims to have been a barber in his corporeal life. His insistence that his former occupation makes him qualified to dispense opinions on medical issues becomes a running gag. Despite being a ghost, he often fears for his safety.
• Annemarie Blanco (Season 1); Rachael Lillis (Season 2) as Teodora Villavicencio, the human of a 17-year-old girl who actually hails from the future, as shown by her modern attire and mobile phone, which contrast with the show's 19th-century setting. It is later revealed that she is not actually dead but rather comatose due to injuries sustained in a truck accident; a mysterious lady subsequently taught her the power of astral projection and advised her that Leo would need her help, prompting Teodora to send herself back through time. Consequently, Teodora possesses some abilities that normal ghosts lack, such as immunity to the power of Medusa and greater skill at manipulating physical objects. She also has a rather fierce rivalry with Marcella. Despite that, she was willing to resuscitate Marcella when she died, possessing her body to perform CPR on herself. Teodora can seem rather selfish and hard-headed at times, but in reality she is a caring, brave, and kind-hearted girl who is willing to risk it all to protect her friends, particularly Leo. In the second season, it's revealed Teodora has gradually been falling in love with Leo, attracted to his bravery and desire to help those in need.
• Paul Tei as Alebrije, a flamboyant, kindhearted yet dimwitted strange creature of various colors who appears in different forms depending on the observer, though always retaining his unique color scheme. His real name is apparently hard to pronounce, so he is simply nicknamed Alebrije by the group. He is portrayed quite differently compared to the films in terms of appearance and personality. Alebrije is portrayed as a comical optimistic character who tries to keep the team together, while also presenting his own knowledge when needed.
• Cydney J. Fam (Season 1); Jenna Lamia (Season 2) as Marcella, an extremely beautiful 16-year-old girl, and Leo's new girlfriend who comes from a family who are accused of being sorcerers. It is eventually revealed that her mother was indeed a sorceress, but one who refused to aid Baba Yaga and Nu Gui in their plans and was thus attacked and left gravely injured; Marcella later inadvertently gained powers from her mother after touching her comatose form. Marcella took it upon herself to care for her mother, eventually coming to Leo's village. She eventually befriended Leo, later falling in love with him and having their first kiss.
• Blanca Bassion as Baba Yaga, an evil witch who initially appears to be in league with Quetzalcoatl but is later revealed to have been enslaved by him; she seeks freedom and vengeance on her "master." She and her comrade Nu Gui attempted to persuade Marcella's mother to join them in their plotting.
• Paul Tei as Friar Godofredo, a Friar who mentored Leo and later informs him of the existence of the Brotherhood, a noble organization dedicated to fighting evils such as Quetzalcoatl.
• Al-Kesne Shaw as Quetzalcoatl, a legendary deity who is described as a force of creation "when he's in a good mood"; he is the series' main antagonist and seeks to destroy the world so that he can remake it. Previously he did so for humanity's benefit, but was then trapped in an alternate dimension, leading him to seek vengeance. He later tricks the heroes in attempting to destroy the Esfera, an egg containing the next Quetzalcoatl, in order to prevent his own demise.
• Lissa Grossman as Abuelita, Leo's grandmother.
• Andrio Chaverra as Thomas Decatur, a New Jersey inventor who becomes one of Leo's allies.
• Gerald Owens as Fenrir, the legendary wolf of Norse mythology who seeks to bring about Ragnarok; he is Quetzalcoatl's ancient rival and seeks to destroy him. He is chained to the world tree Yggdrasil and guards access to it, as it serves to connect all points of space and time.
• Owen Almeida as Akihito, a young Japanese nobleman who is heir to both the magical Sword of Dawn and leadership of the Brotherhood, a noble organization dedicated to thwarting mystical menaces such as Quetzalcoatl. Initially leading a sheltered life that led to his own people despising him, Akihito found the courage to take up his family sword with help from Marcella. The sword enables Akihito to undergo a transformation similar to that of Ultraman, in which he dons a mystical suit of armor and grows to gigantic size.
• Paula Barros as Nu Gui, a Chinese witch and member of Baba Yaga's coven; she was once the daughter of an Emperor, but betrayed him in order to obtain immortality, though the process drove her mad. She is initially contemptuous of Yaga for siding with Quetzalcoatl, but later joins him in Baba Yaga's place; however, like Yaga it is revealed that she serves unwillingly. Barros also provides the voices of Teodora's Mom, Teodora's cellphone, and Akihito's overprotective Vizier.
