The Main Heroes
- Voiced by: Johnny Rose (English), Benny Emmannuel (Latin American Spanish)Full name: Leonardo "Leo" San Juan
A young man from a small town in 1800's Mexico. Since a young age he has been able to see ghosts and with their help goes on adventures to try and stop monsters...or at least he did when he was younger. Now that he's a teenager, he just wants to be normal, get his weird "leg-ball" game to be popular, and maybe get the new girl Marcella to notice him, but life ain't so easy for young Leo....
- 10-Minute Retirement: After sealing the Big Bad Quetzalcoatl away, Leo's finally earned the respect of his hometown, gotten a girlfriend who accepts him for who he is, and everything's gone back to normal. Then the Big Bad steals away everyone and everything in Leo's hometown as revenge, with Leo and friends barely escaping.
- Adaptational Intelligence: Sort of. Leo was the Smart Guy of the La Leyenda films as well (a role he shared with Alebrije), but although he was incredibly enthusiastic about science and reading, his intelligence was mostly a good sense of logic and experience. In Legend Quest, Leo is extremely intelligent and has the makings of a young scientist. This could be mostly explained to him simply growing up, however, especially given his aforementioned love of science at the young age of 9.
- Adaptational Jerkass: To a minor extent, but it's there. In the original movies, Leo bordered on All-Loving Hero who was exceeding kind, patient and gentle, almost to a fault. Every time he did lose his patience or snap, it was pretty much justified, or at least understandable under the circumstances. Leo in Legend Quest is still a genuinely good-natured Nice Guy who will always do the right thing in the end, but his patience is a lot shorter and he gets angrier a lot more often.
- Adaptational Personality Change: In a sense. By the later La Leyenda films, especially La Leyenda del Chupacabras, Leo grew into a more mature, no-nonsense and morose character. He's a little more jovial, goofier, socially-awkward and deadpan in Legend Quest. Still, most of his personality traits remain, if slightly tweaked. He's still selfless, forgiving, kind-hearted, intelligent, adventurous and still plays the straight man to his friends quirks.
- Adorkable: Not as much as when he was a kid, but teenage Leo has his moments. Theirs just something very endearing about him geeking out over seeing Mount Vesuvius in person.
- "Awesome McCool" Name: A downplayed example, but Leo has had his fair share of cool nicknames over his many adventures. Namely, "The One", "The Socrates of Puebla" and "The Lion".
- Blessed with Suck: Leo's opinion of his power to see and converse with spirits. Understandable, considering its long-term results on his public image.
- His status as The Chosen One in the prophecy is revealed to be this in the 13th episode.
- The Chosen One: Only the Lion can defeat the Snake. Leo means lion as you may know. Later episodes hint that he might be The Chosen one for other prophecies as well.
- Badass Normal: He's tasked with protecting the world from supernatural evils, yet his only real power is seeing and conversing with spirits. He compensates for this by being a Guile Hero.
- Book Dumb: He's not stupid, but he is still an 19th century peasant who never left his village before, and so is ignorant of a lot of things we would consider obvious.
- Butt-Monkey: He lacks the intangibility of his ghostly companions, the hardiness of Alebrije, and Marcella's magic powers so his suffering is much more frequent and accute.
- Cheerful Child: Mostly during La Leyenda de la Nahuala, and mostly in the presence of those he trusted. In those situations, Leo was very cheerful, kind, friendly and sweet. Leo's constant, increasingly darker adventures dimmed this considerably.
- Exhausted Eye Bags: Constantly.
- Friend to All Living Things: Subverted. Leo likes animals, but animals do not like Leo.
- Guile Hero: Since Leo doesn't have any powers (aside from seeing and conversing with spirits), he has to rely on his wits to defeat supernatural threats.
- He captured Baba Yaga, one of the world's most powerful witches, merely by sneaking into her house and building a fully-functional witch-trap around her while she was busy scrying.
- He manages to trick Mister Madera, a frighteningly competent sentient puppet who had already fed on the souls of his entire team and turned them into puppets, into being locked into his airship's liferaft just long enough to be sent to be incinerated by a nearby active volcano.
- He Who Fights Monsters: Leo's desire to save his village and family from Quetzacoatl's grasp almost gets the better of him in Episode 5, as he argues with Teodora over whether or not they should ignore the Vodnik's soul-stealing and instead focus on Baba Yaga and defeating Quetzacoatl as fast as they can, even if that means abandoning Alebrije, who had his soul taken from him by the Vodnik while acquiring the last ingredient for the Veritas potion. He backs off on this attitude, however, after hearing from the Vodnik how much he had sacrificed in pursuit of his twisted goal.
- Kid Hero All Grown-Up: His pre-teen years were filled with heroics against supernatural evils and being joined in those heroics by ghosts and a mythical shape-shifter. As a teen, he wants out of the hero business because everyone thinks he's crazy.
- Refused the Call: A belated version of this trope as Leo, now a Kid Hero All Grown-Up, is still needed to save the world, but he rejects it as wants a chance to live a normal life and has people does not think he's nuts. Unfortunately, the call knows where he lives.
- Foil: The climax reveals he is this to Teodora. Where he tried to refuse the call, Teodora jumped at it even giving up being with her family in order to save the world.
- Generation Xerox: In the La Leyenda film series, Leo's paternal Abuela (then named Toñita San Juan) managed to fend off La Nahuala, saving the souls of Xóchitl and Teodora in the process. Leo does much the same in La Leyenda de la Nahuala, freeing the two girls from the Manor as a whole.
- Possibly with his father as well, though not much is known about his father since he's been dead ever since Leo was a young kid. What we do know about his father is that he was very brave, courageous and kind. Toñita described him to be very similar to a then 9-year old Leo.
- I Just Want to Be Normal: Leo desperately wants to be this, but can't as talking to ghosts on a regular basis doesn't exactly paint a stable mental picture to people who don't believe in them.
- Science Hero: Leo isn't so much a science hero yet, but the show implies he'll eventually become one, with Thomas Decatur saying he'll make a fine scientist one day (which Leo was elated at). Leo has also been shown to have a great love for science and logical mindset.
- The Smart Guy: Leo's intelligence is by far his greatest asset. Despite his young age, Leo has shown considerable skill in engineering and has some degree of knowledge regarding the world outside of Puebla, given his geeking out over Mount Vesuvius. It's even foreshadowed Leo would grow up to become a scientist of sorts.
- Took a Level in Kindness: Leo was pretty grumpy and short-tempered at the start of the series. After his adventure started and he began to travel the world, his kind and selfless nature started to shine through more and more.
- War Is Hell: In the La Leyenda timeline, Leo became a war veteran in either his Preteen or early Teen years. Needless to say, his experiences in the war were not pleasant. Leo never actually saw proper combat in the war, but he did witness several soldiers on both sides, who he befriended, die horribly and was nearly executed by firing squad, not to mention the attempted murders against his and his brothers life. War sucks. Leo being a war vet seems to have been retconned out of his personal history during Legend Quest.

A ghost girl who is a constant companion for Leo. While she may seem unconcerned with the goings-on of her surroundings, make no mistake - she cares deeply for her friends and will give anyone a bad day if they hurt them. Weirdly, despite being in the 1800's, she dresses like a 21st-century girl and even owns a smartphone....
- Adaptational Heroism: In the La Leyenda series, Teodora would do the right thing...eventually. She usually had to be bribed or coaxed into doing it by Leo first. In Legend Quest, Teodora is downright heroic who gave up her life with her loving parents in order to save the world with Leo.
- Adaptation Personality Change: Aside from her aforementioned heroism, Teodora's entire personality was pretty much reworked from the ground up. In the La Leyenda movies, Teodora was an overly emotional, spoiled rotten Royal Brat Faux Action Girl who blurted out pop-culture references who annoyed most of her friends and rarely did anything to actually help. Sure, she's retained some of her traits, but they're much less exaggerated than before and she's a lot more willing to fight her way out of situations, becoming among the most aggressive members of the team.
- And I Must Scream: From what Marcella says, before she learned how to use Astral Projection, Teodora was aware of everything going on around her while in her coma, but unable to wake up or communicate with anyone.
- Astral Projection: Is capable of doing this thanks to Catrina's teachings.
- Chekhov's Gun:
- Teo's smartphone. It has an internet connection, meaning she has the freaking internet in the 19th century. As a modern teenager, she's somewhat more worldly and educated than everyone except maybe Alebrije. As such she's the only one who recognized a Japanese town and the only one with even the slightest idea of how to act appropriately.
- Her teal glow despite every other ghost glowing white. After its already shown she is actually an Astral Projection, Leo later gets forcibly removed from his body and he too has the same glow in spirit form confirming that the teal color is an indicator that the spirit's body is still alive.
- Dark Secret: Teodora is still alive in the 21st century, albeit in a coma, and her 'ghost' form is actually her astrally projected soul.
- Gallows Humor: She prefers dealing with her grief through humor.
- Jumped at the Call: When offered the chance by Catrina to join Leo and save the world, Teodora doesn't even hesitate.
- Lovable Alpha Bitch: She behaves and talks like a typical "Fresa" (the mexican equivalent of the Valley Girl), but essentialy she deeply cares by her friends and allies.
- Meaningful Name: Teodora/Theodora are feminine forms of Theodore, "Gift of God." Likewise, Teodora (and the information on her phone) save the team on multiple occasions. Plus, her family loves her dearly, and she was literally recruited by a benevolent goddess.
- Overly Long Name: Her full name is Teodora Vicenta de la Purísima Concepción de la Inmaculada Trinidad Villavicencio. Funnily enough, her giant name was actually shortened. In La Leyenda, her complete name was Teodora Vicenta de la Purisima Concepcion de la lnmaculada Trinidad Villavicencio, Duchess of "You'll See Now", Marquise of "Whew" from La Condesa vicinity. Of course, Leo just called her "Teodora, all of that".
- Taking the Bullet: When Baba Yaga tries to kill Leo in order to power a spell, Marcella jumps in front of him then Teodora phases through them both and and takes the hit.
- Tsundere: She doesn't like openly showing her softer side but she is one of the more caring characters when you get to know her.
- Walking Spoiler: Take a good long look at the main page and her character tropes.
- Voiced by: Oscar Cheda (English), Andrés Couturier (Latin American Spanish)
A cowardly ghost who acts as the team scholar. He may be a coward but don't think he won't help his friends when they need it.
- Cowardly Lion: Is scared stiff when facing the legends, and is usually the first to suggest retreat. However, he still manages to overcome his fears and fight alongside his friends.
- Badass Boast: Delivers one right before distracting the Mart in the dream-world:
- But I Read a Book About It: Occurs in "Jersey Devil". With no one in town willing to defend Leo and the group in court, Don Andrés volunteers to defend them, claiming to have been a licensed barrister, though he clarifies to Leo that he just read a book about it on a voyage across the ocean.
- Fake Ultimate Hero: Don Andrés was pretty much this in life. He scammed towns into giving him money for his services in protecting them from non-existent supernatural threats. Then when he met an actual monster, he turned tail and ran away.
- Miles Gloriosus: Whilst alive, Don Andrés made a living as a scam-artist, posing as a conquistador experienced in 'protecting' villages from non-existent legends for a fee. The one time he actually faced a real legend, namely the Nicht Mart, he turned tail and ran. Spending time as a ghost has reformed him into a Cowardly Lion.
- My Greatest Failure: Abandoning the people of Steinau to the Mart. Thankfully, his ghostly nature and friendship with Leo enable him to atone for his failure. Cementing his change into a better person, he doesn't even show himself to take credit for his part in the town's salvation.
- What You Are in the Dark: When trapped in his own dream-world by the Mart, who has also captured a tag-along Leo, Andrés doesn't run - he stands his ground and fights without fear or hesitation.
- Voiced by: Paul Tei (English), Ricardo O'Farrill (Latin American Spanish)
A mythical creature that looks different to everyone who sees him. He may be a bit dimwitted but he makes up for it by having a big heart and easily understanding the feelings of his friends.
- Adaptational Nice Guy: It's not like Alebrije wasn't a nice guy in the movies, he was actually a quite good hearted guy, but he enjoyed teasing his friends and could get rather spiteful at times. In Legend Quest, Alebrije is The Heart of the team. Though to be fair, Alebrije slowly turned into The Heart in La Leyenda as the series went on, especially by La Leyenda del Chupacabras, and often played the role of the Straight Man along with Leo.
- Adaptation Personality Change: Could you believe Alebrije's reveal scene in La Leyenda de la Nahuala emphasized how intelligent and studious he was? His intelligence started to mellow out as the series went on, but he was always much more logical than Don or Teodora.
- A Dog Named "Dog": Alebrije is what you'd call his species of mythological creature, but his friends have a hard time pronouncing his actual name.
- A Form You Are Comfortable With: Alebrije's form changes depending on who's looking at him. He sometimes appears as a variety of animals (goats, beavers, etc.) or as a completely different supernatural entity entirely (an imp, a triplecorn, etc.). Every form he's seen as, however, still has his color scheme, leading the viewer to note the weirdness of his appearance.
- Awesome, but Impractical: His ability to fly, which isn't very fast and can't get him very high.
- Beware the Silly Ones: Leads the souls of the Vodnik's victims to drown him. Keep in mind Alebrije is the goofy, lovable heart of Leo's team.
- The Big Guy: He's the physically strongest member of the group.
- The Heart: He is usually the one giving pep talks and helping settle arguments between the heroes.
- Mix-and-Match Critters: The characters see him as a bipedal dinosaur creature.
- The Unpronounceable: Refered to as "El Alebrije de la Biblioteca" in the films, He's simply called "Alebrije" because his real name is too hard to pronounce.
- Voiced by: Cydney J. Fam (English), Alondra Hidalgo (Latin American Spanish)
The new girl in Leo's town and one he has a big crush on. Marcella is an adventurous girl who is always ready to stand up for her friends...maybe a little too ready. She has a secret she doesn't want anyone to know and it might just cost her her friends if she holds onto it.
- Action Girl: She loves using a type of Martial Arts in fights. Then there is the fact that she is a powerful witch.
- Composite Character: Of movie characters Xóchitl and Valentina. Marcella is basically a living and older version of Xóchitl with Valentina's color scheme, tomboyish action girl persona and motivations. She also shares Xóchitl's magic and supernatural origin.
- Dark and Troubled Past: Her mother was one of the most powerful witches in the world, but unlike most witches in the series, she was a good person. When Nu Gui and Baba Yaga came to her to try to recruit her to their coven, she told them to leave. This resulted in a battle that left Marcella's home in flames and her mother completely catatonic. Marcella has been secretly caring for her mother for years as well as dealing with her awakened witch powers.
- Dark Secret: She's one of the world's most powerful witches, and is part of Baba Yaga and Nu Gui's coven. Not that she joined them to be chums....
- The Dutiful Daughter: Lacking any assistance from others due to their fear of her inherited powers, she cares for her comatose mother in secret. In fact, the first thing she thinks about upon first regaining consciousness after being resuscitated by Teodora is the moment which led her to become this.
- Leeroy Jenkins: She has a bad habit of just running into fights with little planning and often needs help getting out. This trait gets her killed at one point as her coven sisters use her to awaken the Terracotta Army. It took Teodora setting aside her jealousy to bring her back to life.
- Revenge Before Reason: Her rash attempt to get revenge on Baba Yaga and Nu Gui for rendering her mother catatonic fails catastrophically. By joining their coven, she's subconsciously-bound to follow their summons spell; furthermore, by the time the ritual she's helping them complete is nearly done, she realizes the others intend to use her as the final ingredient, rendering any attempt at sabotage moot.
- Suspiciously Similar Substitute: As mentioned above, Marcella shares several traits with Xóchitl and essentially fufils the same role as her, that of a more tomboyish foil for Teodora and love interest for Leo. However while Xóchitl and Teodora were friends from the start (even if Xóchitl found her annoying, and for good reason) Teodora and Marcella aren't exactly on good terms throughout most of Legend Quest.
- Third-Option Love Interest: She replaces Leo's two love interests from the movie pentalogy.
The twins, Finado and Moribunda, a pair of diminutive sugar skull-headed children who help run the ship and are eerily capable at seeking out clues about the Brotherhood that their taller allies often miss.
The Villains And Monsters
- Voiced by: Al-Kesne Shaw (English), Dan Osorio (Latin American Spanish)
The all powerful Snake God of the ancient Aztec people. While usually a benevolent god, he has since decided humanity isn't worth his time.
- Big Bad: Of the first season, though ironically enough he is also the Big Good after he is reborn
- Blow You Away: Literally too, as he breathes out strong winds against the protagonists in the final battle. As the Aztec god of wind and air, it makes sense.
- Composite/And Decomposite Character: Essentially he's a reversal of the Tezcatlipoca - Quetzalcoatl in Aztec myth. In mythology, Quetzalcoatl is the "White Tezcatlipoca", being essentially a benevolent aspect of the four-sided god, while here the Tezcatlipoca-analogue is the "Black Quetzalcoatl". He also doubles as the Norse Nidhogg, being an underworld serpent rival to Fenrir.
- Enemy Without: The current Quetzalcoatl to the one in his Esfera.
- Goo Goo Godlike: His newly-born self is intelligent enough to speak articulately and powerful enough to travel through time to bring someone back from the dead. Not to mention that he usually devastates human civilization whenever he's fresh out of his egg.
- Manipulative Bastard: He made plans for someone destroying the Esfera thousands of years in advance by spreading the legend that whoever stabbed it gained power, unaware that destroying it ensured he got to stay alive.
- Metamorphosis: He starts off looking like a large flying snake then eventually becomes a massive Snake Person.
- Misery Builds Character: The logic behind raining calamities on mankind whenever he reincarnates as the surviving humans tend to be stronger and smarter than their predecessors. However soon after he reveals that he just wants the world for himself (at least in this cycle) and is tired of serving "a race of ants."
- Rage Quit: Essentially the reason why a usually benevolent god would want to destroy the world. It's further explained that Quetzalcoatl is tired of the never ending cycle of death and rebirth just for the benefit of people who don't even worship him anymore.
- Reptiles Are Abhorrent: Played straight at first but then it's revealed that the Big Good is also Quetzalcoatl reborn.
- Ironically the benevolent newborn Quetzalcoatl is even more serpent-like than his malevolent predecessor.
- Saying Too Much: He lets his plan slip when he shows too much anger at the Celestial Point being missing, instead of being happy that the only weapon capable of destroying the Esfera is gone. Leo quickly catches on that Quetzacoatl actually needs somebody to stab the egg.
- Voiced by: Blanca Bassion (English), Erica Edwards (Latin American Spanish)
A witch who despite being a servant of Quetzalcoatl, is the the most consistently appearing antagonistic force on the show, as well as the one whose caused the most bad things to happen to the team.
- Ambiguous Situation: Its not actually clear if Fenrir killed her, we do see that she is chained up next to him and we see the two in shadow as Baba screams, but its never shown if he actually ate her, or if Fenrir has other plans.
- Batman Gambit: Pulls this off in episode 8. Following Alebrije's Heroic Sacrifice two episodes prior, Baba Yaga found him and turned him into the titular Kaiju, then sent him to destroy Japan, and Akihito's spirit. While that plan ultimately fails and Alebrije is returned to normal, Baba is still able to get what she wanted from Japan... the Celestial Point.
- Blue and Orange Morality: Claims to be above "mortal morality", caring only for the fate of witches.
- Didn't See That Coming: She is understandably caught off guard when her attempts to sacrifice Teodora reveal the girl isn't even a ghost, even dropping the trope name in conversation.
- Dragon with an Agenda: She's only working for Quetzalcoatl because he's trapped her under him.
- Hero Killer: By the end of the first season, She's killed both of Team Legend's female members via magical sacrifice, Marcella in Episode 9 and Teodora in Episode 12. Fortunately, neither stays dead for long.
- Impersonating an Officer: Rather, a clergyman, but this is how Baba Yaga makes her debut. At the end of Episode 2, It's revealed that Jacob, the town parson of Leeds, was locked in a closet and replaced by the witch weeks before Leo and co's arrival.
- Lured into a Trap: Baba Yaga does this (as Aldo the Shepherd) in episode 4. After Leo and Teodora have their argument and Leo's looking for her, Aldo tells Leo that Teodora went to Medusa's lair to try and defeat the Gorgon herself. But when Leo catches up with her, she claims that Aldo told her that Leo went up on his own first. This is the first true demonstration of Baba Yaga's treachery as she lured Leo and Teodora into a trap that she hoped would see both of them killed.
- Villain: "Exit, Stage Left!": In episode 5, Baba Yaga takes advantage of the heroes celebrating their victory over the Vodnik by commanding her house to run away, with her in it, after they leave to rest in the town.
A gaggle of ghoulish monkey-like demons in service of Quetzalcoatl.
- The Comically Serious: Horroroso are often portrayed as silly, childish and incredibly petty. Make no mistake however, Horroroso are just as cruel and vicious as their master. They enjoy playing and toying with their victims, laughing at their misfortune, and Kick the Dog kicking them while they're down. They're shockingly intelligent and act more like younger humans than monkeys, not to mention they can perform feats of superhuman strength. Subverted in the fact that despite their intelligence, they often get confused over trivial matters.
- Maniac Monkeys: They happen to look like monkeys.
- Monster of the Week: For Episode 1. In their case, they become recurring mooks for the rest of the season.
- Starter Villain: For the series at large.
- Zombie Apocalypse: They create this by sucking the life force from most of Puebla's townsfolk and turning them into zombie-like beings.
Once a human child, the Jersey Devil was the 13th and final child birthed by Mother Leeds who cursed him to become the demonic monster he is now.
- Mix-and-Match Critters: The Jersey Devil is a hooved, almost draconic goat-like being with jet black fur, bat-like wings and a forked tail.
- Kryptonite Factor: The monster is vulnerable to iron. Something that the people of Leeds didn't realize when they first drove him away with iron cannonballs.
- Monster of the Week: For Episode 2
- One-Winged Angel: According to his origin, The Jersey Devil was born a normal human baby. But soon enough, he grew to become a monster.
- 13 Is Unlucky: He's the 13th child in a liter of Massive Numbered Siblings.

An alp who has the power to deliver bad dreams, as well as a shocking connection with Don Andrés
- Dream Weaver: The Nicht Mart can induce nightmares on people with a touch, and can personally appear in them to make things worse. If the victims realize they're dreaming however, they can turn the tables on the monster within the dream.
- Emotion Eater: The Mart feeds off the fear of others.
- It Amused Me: Normally, the Mart doesn't stay in a single town for long, But he made an exception with the German town of Steinau, fully intent on haunting them for eternity given their gall to stand up to him... and of course, Don Andrés' actions during his life.
- Monster of the Week: For Episode 3
- Your Worst Nightmare: The Nicht Mart's victims are forced to endure this whenever they fall asleep.
The infamous Gorgon herself. After being slain, She's returned as a ghost with her petrification abilities no longer affecting living humans... but now affecting ghosts.
- Deader Than Dead: Ghosts petrified by Medusa's gaze crumble to dust when exposed to sunlight. Not even killing her brings back those slain this way.
- Hoist by His Own Petard: TWICE! The first time was when she met her initial end at the hands of Perseus. When the cowardly hero couldn't muster the courage to truly fight her. He had her see her own reflection in his Bronze Shield, turning her to stone. Afterwards, Perseus cut her head off as a trophy, killing her in the process. The second time was when Teodora was caught by Medusa's Ghost while trying to save Leo... and to everyone's surprise, was unaffected by her Deadly Gaze. Teodora then took a selfie with the Gorgon and showed it to her, which ended up having the same effect as seeing her own reflection. Afterwards, Medusa's pertified body was knocked into the lava below... presumably killing her for good.
- Monster of the Week: For Episode 4
- Taken for Granite: Medusa's schtick as usual.

Once a human toy maker, he eventually got fed up with the impure souls of adults and changed himself into a frog-like monster with dark magic. Now he steals the souls of children, trying to keep them from coruption.
- Children Are Innocent: While the Vodnik can steal souls from just about anybody, he prefers doing so to children as their souls are purer than those of adults.
- Enemy Eats Your Lunch: At one point, The Vodnik eats Leo's pretzels just to spite him. Subverted because unbeknownst to him, Leo spiked the pretzels with a magic potion that will compel him to answer three questions.
- Hypocrite: Vodnik claims to be saving children from corruption by adults, but he himself is just as cruel as any normal adult would be.
- Knights and Knaves: Vodnik is on the receiving end of this when Leo tricks him into consuming a magic potion that will compel him to answer three questions. The catch... Only two of the answers will be true with one of them being an outright lie. Given the simplicity of his objective, Leo elects to get around this obstacle by asking the same question thrice.
- Lured into a Trap: This is how the Vodnik captures Alebrije. Disguising his voice to be that of a gentle woman in peril to attract Alebrije, Vodnik used his kind and gentle nature against him.
- Monster of the Week: For Episode 5
- The Dog Bites Back: Once liberated, the souls of the children that the Vodnik kidnapped (along with Alebrije's soul) gang up on their former captor and drown him before returning to their bodies.
- Villain Teleportation: The Vodnik can travel between bodies of water of any size regardless of physical connectivity; from lakes to puddles.
- Was Once a Man: The Vodnik used to be human, but transformed himself via dark magic.

The devourer of worlds, the wolf god, and bringer of Ragnarok. Or at least he would be if he wasn't chained to the World Tree, Yggdrasil.
- Annoying Arrows: He has several arrows lodged in his back but they don't bother him.
- Canis Major: He is huge. He eats worlds, after all.
- Chained to a Rock: He's stuck guarding the entrance to Yggdrasil until Ragnarok although the chain's length is rather generous.
- Deal with the Devil: He makes a deal with Leo and co. to allow them use of the world tree if the give him a powerful artifact of Quetzalcoatl's, but since Fenrir is actually worse than the snake god, the team reneges until they "repay" it by feeding him Baba Yaga near the end of the first season.
- Enemy Mine: He's as much an enemy of Quetzalcoatl as the heroes and is even willing to help them out. They back out as soon as they realize that he'll devour all realities if he's freed.
- Extreme Omnivore: He devours entire worlds and can even eat spirits. In his own words "I can eat anything".
- Faux Affably Evil: He speaks to Leo and Company in a polite and calm tone but only after he figures out Leo is The Chosen One and could be useful, beforehand he tried to eat them on the spot and after they deny him the Esfera he goes back to a snarling monster.
- Greater-Scope Villain: Luckily he is chained up because while Quetzalcoatl wants to make the world a place where only the strong survive (which exculdes humans) Fenrir just wants to devour everything.
- Monster of the Week: For Episode 6... although in his case, he has the potential to become a Big Bad himself in the future.
- Mr. Exposition: Among other things, he's the entity that reveals the prophecy to the protagonists as well as how Quetzalcoatl's doom is tied to the Esfera although he chooses to omit a number of crucial details to further his own agenda.
- Skull for a Head: The top part of his head is a wolf skull with large horns instead of ears and eyes made of blue fire.
- Wild Card: While Quetzalcoatl actively wanted someone to destroy his Esfera, having Fenrir feast on it was most definitely not one of the ways he wanted it to happen since it will give the wolf an unfathomably huge power boost.

The Bactus are parasites from Finland who stole teeth from various people from Vikings to civilians in order to eat them. Recently, they migrated to London, England and started up an Orphanage in order to set some teeth.
- Anachronism Stew: The Bactus are supposedly from Finnish Mythology, but actually get their name from a 1948 Norwegian children's book.
- Anti-Villain: Despite being a monster disguised as a human, Ms. Wisp is very motherly and caring towards her Orphans, feeding them as much food as they want and going out of her way to protect them, even if it was so she can obtain their teeth for the Bactus.
- Framing the Guilty Party: Rather, Framing The Creepy Good Guy. Due to his creepy nature, Dr. Blackpulp was seen as a villain by the Orphans, a falsehood perpetuated by Ms. Wisp to keep him from interfering with the Bactus' machinations.
- Glass Smack and Slide: The Tooth Fairy ends episode 7 doing this.
- HeelFace Turn: Thanks to Team Legend taking pity on her, Teodora decides to revamp her image so she'd have a less violent and much more peaceful method of consuming children's teeth. Essentially giving birth to the titular Tooth Fairy.
- Monster of the Week: For Episode 7... until the end where she reforms.
- Not Evil, Just Misunderstood: The Bactus only stole the teeth out of people because they need to eat them to live. Once Leo and the others realize this, they're able to negotiate and work out a compromise.
- Orphanage of Love: As Ms. Wisp, The Bactus Queen runs an orphanage like a kindly old lady.
- Toothy Issue: The Bactus end up causing this.
- Solid Gold Poop: Being a Bactus, she literally poops out gold as a byproduct of eating teeth.
A giant monster who seems to be attacking Japan for no reason. Later revealed to actually be Alebrije, turned into a Kaiju by Baba Yaga.
- Brainwashed and Crazy: Thanks to a magical control collar placed around his neck by Baba Yaga.
- Fighting Your Friend: As the Kaiju, Alebrije ends up fighting the rest of Team Legend
- Fire-Breathing Diner: Done realistically when Don Andrés says "They say the way to a man's heart is through his stomach." and Leo gets the idea to catapult a canister of wasabi into the Kaiju's mouth.
