Captain Koinelius Tunar is the commanding officer of a sand ship manned by Fishmen. He holds an intense grudge against a creature called the Ramlak, which took one of his legs and ruined his people's homeland.
Tropes associated with The Captain:
- Animal Nemesis: Inverted. Tunar, a Fishman, has sworn vengeance on The Ramlak, a giant Planimal, a Man-Eating Plant/Giant Squid Hybrid Monster. It destroyed his home and took his eye and leg.
- Anti-Hero: Deconstructed, as it becomes apparent that his quest to kill the Ramlak has become all-consuming.
- An Arm and a Leg: Type 3. Tunar lost his leg (and an eye) to the Ramlak, and now uses a peg-leg.
- The Captain: Deconstructed. His fixation on the Ramlak has steadily eroded the relationship between himself and his crew.
- Determinator: And NOT in a good way, as he relentlessly persues the Ramlak:Tunar: "I'll follow ya straight to the flamin' pits of Magmel before I give you up!"
- Fish Person: He's a fish man.
- He Who Fights Monsters: His obsession with killing the Ramlak has made him callously indifferent of his people's suffering.
- Homage: To Ahab of Moby-Dick. He even quotes him at the end when the Ramlak pulled him in after getting harpooned, in the same exact way Ahab died. He may also be a very loose adaptation of Captain Hammerhand, from the original series.
- I've Come Too Far: He refuses to give up on hunting the Ramlak because of everything he's lost to it.
- Lack of Empathy: Illustrated towards his long-suffering crew, who he frequently dismisses as weak.
- Punny Name: His first name is a play on "Cornelius" and "Koi", while his surname is a play on "tuna".
- Revenge Before Reason: All he cares about is getting even with the Ramlak.
- Shadow Archetype: To Lion-O. Like Lion-O, he too lost his home to a horrible monster, one that he wishes to destroy at all costs. Seeing where that mindset eventually leads convinces Lion-O to move past his own inclinations of Revenge Before Reason towards Mumm-Ra.
- Weird Beard: Koi whiskers as facial hair.
- Voiced by: Atticus Shaffer (child), Patrick Cavanaugh (adolescent), and James Arnold Taylor (adult, elderly)
Emrick is a member of the Petalars, a small race of Plant Aliens who've been separated from their homeland for generations. They live for about a day! Despite this trait, he's a highly optimistic Petalar who possess an upbeat and adventurous attitude.
Tropes associated with Emrick:
- Ascended Fanboy: He becomes a warrior because he idolizes Lion-O and ultimately succeeds in becoming not only a warrior but a warrior leader.
- Badass Adorable: Capable of going toe-to-toe with opponents many times his size. Not that 'many times his size' is particularly big, but it's still impressive.
- Badass Mustache: In adulthood, he gets a dashing Errol Flynn 'stache.
- Cheerful Child: An enthusiastic young Pollyanna, quite convinced that, despite being trapped in the Briar Woods for generations, Lion-O and his ThunderCats will help them find a way back home.
- Constantly Curious: He's full of questions for the ThunderCats. Lion-O says he reminds him of himself at that age, implying that he was one as well.
- Final Speech: Assures Lion-O that It's the Journey That Counts
- Garden Garment: Wears green leaves that look like they may be in fact be part of his body.
- Heroes Prefer Swords: Makes one out of a twig to better model himself after Lion-O
- Hot-Blooded: His one constant trait, mirroring Lion-O.
- Intergenerational Friendship: An interesting variation. Lion-O is the elder, with Emrick as his much younger friend, but thanks to the Petalars one-day lifespans, Lion-O sees Emrick become the elder.
- The Leader: In adulthood, look to this one to give the Rousing Speech.
- Motor Mouth: During his youth. Luckily his mouth's small enough to be stopped with a little finger.
- Plant Person: All of the Petalars.
- Retirony: Dies before he can ascend the Cliff of Winds, (an uncoiled fern) and ride an updraft to his ancestral home.
- Tag Along Kid: He's like the little kid brother Lion-O never had. For about ten minutes, anyway.
Leo is Lion-O's ancestor, Commander Mumm-Ra's second-in-command and leader of the Animal rebellion.
Tropes associated with Leo:
- Adaptive Armor: Using Power Crystals as Amplifier Artifacts, his Claw Gauntlet can transform into a set of custom gold Lion armor.
- Astonishingly Appropriate Appearance: Like his descendants, his mane and eyes perfectly echo the hues of his weapon, but he lacks the justification of it being an ancestral birthright.
- Commanding Coolness: Like his immediate superior, also holds the rank of Commander (likely lieutenant commander)
- Cool Sword: He invented the Sword of Omens.
- In Another Man's Shoes: What we see of Leo's behavior is actually Lion-O performing a compulsory Vision Quest while being made to re-enact Leo's historical actions.
- Not What I Signed on For: For a while, he genuinely believed that Mumm-Ra could bring order to the universe. When Mumm-Ra demonstrates that he's willing to murder an entire star system to forge a super-weapon, he swiftly decides to form La Résistance in secret.
- Occult Blue Eyes: Blue-green eyes, like his descendants
- One Head Taller: Leo is a head shorter than his girlfriend Panthera. In fact, Leo seemed shorter than everyone in Commander Mumm-Ra's service.
- Pretty Boy: Lampshaded by his girlfriend PantheraPanthera (during a riot): Are you gonna stand there and look pretty or are you gonna fight?
- Rebel Leader: He inspired Mumm-Ra's prisoners to stand up to him.
- Voiced by: Corey Burton
Captain Tygus is Commander Mumm-Ra's leader in the field, whose operations obtained the War Stone. Like other Tigers, he fought against Leo's Mutiny against Mumm-Ra. His clan was banished for this reason.
Tropes associated with Captain Tygus:
- The Captain: The hands-on, field-leader type, who conducts a one-man assault on a heavily guarded tower powered by a MacGuffin he's Plundering for his Commander.
- Expy: Of Tygra. Lion-O/Leo even lampshades the man's doubt in his plan:Lion-O/Leo: "A tiger underestimating me. I'm not surprised."
- Eyepatch of Power: Wears a Scouter
- Space Marine: Highly efficient against the hostiles that would stand in the way of his obtaining the Warstone.
- Unwitting Pawn: In a MacGuffin Delivery Service. He had no idea Mumm-Ra was just using him to get what he needed to make a weapon.
- Voiced by: Cree Summer
Leo's beloved and coordinator of the rebellion.
Tropes associated with Panthera:
- Action Girl: Brings it in a staged prison break in "Legacy." Motive force behind the rebellion in "Birth of the Blades."
- Big Damn Kiss: Shares one with Leo as Mumm-Ra's spaceship/pyramid goes plummeting towards Third Earth.
- I Want You to Meet an Old Friend of Mine: Cree, of course, voiced Max on Batman Beyond, so has played the faithful partner to a Will Friedle character before.
- Lady of War: She's willing to fight if she has to.
- Morality Pet: In "Birth of the Blades" she was the one who openly questioned Mumm-Ra's brutal orders and caused the initially blindly loyal Leo to start questioning them as well.
- One Head Taller: Inverted. Leo only comes up to her shoulders if you count his hair.
- Reverse Mole: She conspires with Leo while pretending to be loyal to Mumm-Ra.
- Replacement Love Interest: Following Leo's story, she functions parallel to Cheetara as a lion's undyingly loyal confidant, counselor, and Love Interest.
- In "Birth of the Blades," we see more to this relationship. Her initial doubt that Leo can make up for his mistake in believing in Mumm-Ra, leading to the destruction of a star system, not to mention calling him out on it, is rather reminiscent of Pumyra's initial doubt in Lion-O. As is the way she softens after Leo proves that he's thought this through, and is willing to follow through to the bitter end.
- Statuesque Stunner: Panthera towers over Leo and he definitely isn't complaining.
- Tiny Guy, Huge Girl: She's bigger than Leo.
- Undying Loyalty: Her faith in Leo is absolute, even when Leo is unsure of the outcome himself.

Tropes associated with Rezard:
- Voiced by: Stephen Root
A mysterious, eccentric rabbit man who offers Lion-O some much needed advice in the Swordsmans' Town.
Tropes associated with The Drifter
- Aloof Ally: "...if you expect me to help, you haven't been paying attention."
- And That Little Boy Was Me: The Drifter tells a Nameless Narrative of how the Duelist acquired his favorite trophy blade, implying that Lion-O will repeat the mistakes of its previous wielder.
- Badass Adorable: He's a rabbit and a skilled blacksmith.
- Badass Pacifist: "A weakness can be turned into a strength."
- Barefoot Cartoon Animal: Though he inhabits a world full of them, the Drifter specifically Does Not Like Shoes. In youth, he was The One Who Wears Shoes, but abandoned the trait after his loss to the Duelist triggered a deep depression.
- Barefoot Loon: He definitely comes across as one, at least until we learn his Back Story.
- Barefoot Sage: Considering the above tropes, and his Eccentric Mentor relationship with Lion-O.
- Beneath the Mask: His mildly amused, smiling, Brilliant, but Lazy exterior hides a despondent man who still grieves the loss of his masterwork to the Duelist.
- Black Eyes of Crazy: White iris-pupil on black sclera. Very downplayed. He's merely eccentric.
- Brandishment Bluff: Using the willow reed he keeps in his mouth, The Drifter parries the Duelist's attempt to stab Lion-O In the Back, then continues to mock-attack, relying on the Duelist's startlement and reflexive movements to trip him up. The Duelist lands on his rear and the Drifter mockingly sticks the reed up his nose.
- Brilliant, but Lazy: Until Lion-O piques his interest, he's too lethargic to be of any real help.
- Bullet Time: As "a drifter," he induces this at will, to the point where he appears able to Overcrank himself.
- Confusion Fu: Disorients opponents with Not Quite Flight, Nonchalant Dodge, and Brandishment Bluffs.
- Cool Sword: The Sword of Hattanzo, which he made himself.
- Dance Battler: He doesn't even need to throw a punch. At one point, he performs a pirouette in midair.
- Dark and Troubled Past: He lived as a vagabond because of shame at losing his sword to the Duelist.
- Despair Event Horizon: When he lost his best sword to The Duelist.
- Dissonant Serenity: Swinging a sword at his head won't faze him enough to open his eyes, or wipe the smile off his face.
- Distressed Dude: Downplayed. Tends to snag himself on fences and need Lion-O's help getting down, which begs the question as to why he always manages to appear wherever Lion-O is, just when the boy could use some advice...
- The Ditherer: Constantly qualifies his statements. You should take his advice...or don't...he doesn't care.
- Dramatic Wind: Accompanies him, ruffling only his hair and clothes in a given scene, to give an impression of his lightness. In a nod to his Empathic Environment, he frequently uses wind metaphor in his speech.
- The Drifter: Inverted. He poses as someone who quite literally blows into town, and claims to go "wherever the wind takes him" but that translates to floating around the fringes of the Swordsmans' Town, waiting for someone like himself to come along so he can deliver an Adventure Rebuff. By the time he's done with Lion-O, he's come to fully embody his archetype, walking into the sunset.
- Ears as Hair: A rabbit, his ears are as straw-filled, floppy and lank as his hair. In youth, they were expressive and sat high on his head, beginning to droop in defeat.
- Eccentric Mentor: "Take my advice and blow on out of here, or don't. I don't care."
- Enlightenment Superpowers: Not that he cares, but the Drifter has essentially perfected his Not Quite Flight and Nonchalant Dodge through suffering an ongoing major depressive episode. The languid movements that came with his feelings of despair and apathy after his defeat by the Duelist allowed him to become aware of all his flaws as a young combatant.
- Expository Hairstyle Change: The Drifter's hair is long and ungroomed, but as a young man, he wears his hair in a neat, shorter ponytail.
- Eyes Always Shut: Seems to only open his eyes when making particularly trenchant points or being very emotionally engaged.
- Fatal Flaw: His Hubris regarding his swordsmithing skill, assuming he made a sword so magnificent that it could surely beat even a master swordsman, regardless of the skill of its wielder.
- The Gunfighter Wannabe: Became a Scrap Heap Hero out of his failure.
- Hidden Depths: Guess why his entry has so many spoilers; he's much more than just a drifter.
- Homage: To Hattori Hanzo, particularly Kill Bill's swordsmith. As to the fact that he's a rabbit, well...
- Karmic Trickster: He messes with the Duelist in the end to get his sword back.
- Koan: "Willows are weak, but they bind other wood." Translation: You can defeat stronger enemies by tricking them into wearing themselves out through cunning.
- Leaning on the Furniture: Slouches, slumps or sprawls whenever there's a structure in his immediate vicinity.
- Limited Wardrobe: In his case, deconstructed. He's been wearing the same set of clothes for a long time, and it shows in their tattered, patched condition. He's been wearing them ever since his defeat at the hands of the Duelist.
- Meaningful Name: He literally drifts on wind currents as easily as a leaf. His real name, Hattanzo, is a contraction of Hattori Hanzo.
- Meek Townsman: "This is a Swordsmans' town, stranger, and they duel for keeps. Leave, before it's too late. Or don't, I don't care."
- Messy Hair: His dark brown hair is long, unkempt and full of bits of straw.
- Not Quite Flight: A marvelously absurd power to float on currents of wind, the catch being that he does seem to snag himself on tall fences rather frequently.
- Oral Fixation: Constantly chews a willow reed.
- Pintsized Powerhouse: He's much shorter than Lion-O and The Duelist and he proceeds to kick the latter's ass when he tries to stab the former in the back.
- Rascally Rabbit: He's a rabbit who's a Trickster Mentor.
- Retired Badass: Was once "the greatest swordmaker of all time," but hasn't made a sword since his defeat by the Duelist.
- Righteous Rabbit: Yes, he's very eccentric, but he's definitely one of the good guys.
- Scarf Of Asskicking: Amazing, since he manages to kick ass without kicking any ass.
- Scrap Heap Hero: A failed swordsman, but that doesn't stop him from blocking the Duelist's last knife attack with a willow reed.
- The Slacker: "There is such a thing as trying too hard, which is why I prefer not trying at all."
- Stepford Smiler: If his apathy isn't enough of a cue, his oft-present grin hides a deep depression at the loss of his masterwork, his finest sword, to the Duelist.
- Suspiciously Specific Denial: "I don't care," and many variations thereof, a de facto Catchphrase. Over time, the Implausible Deniability of the statement steadily increases to the point where it becomes obvious it's a lie.
- The Trope Without a Title: He says he's "just a drifter, I suppose".
- Trickster Mentor: He's so good at it that Lion-O didn't even get what he was trying to teach him until he's practically already lost the duel. He even gave Lion-O a sword that he knew would break, just to drive the point home.
- Ultimate Blacksmith: Hattanzo himself, maker of the Duelist's best trophy, the Sword of Hattanzo.
- Unreliable Narrator: Downplayed. When telling a story, the Drifter conceals his identity as the protagonist, and his real name in the descriptor of his sword. Lion-O realizes the former, but not the latter, and the Drifter never directly acknowledges the story's implications.
- Waif-Fu A rare Gender Inverted example. Willow reeds kick ass.
- Walking Spoiler: It's hard to talk about him without spoiling how his episode ends.
- Warrior Therapist: Provides a very pointed critique of Lion-O's impatience and poor technical skill.
- Weak, but Skilled: If you're skilled enough, you CAN disarm someone wielding a knife with just a willow reed. In youth, he was its inverse, Unskilled, but Strong.
- Wuxia: His personal genre. Despite not being a trained warrior, he borrows from the Ronin concept, and blows Wire Fu away.

- Cool Old Guy: He's older than the other elephant people and proves on occasion to be a capable fighter.
- Martial Pacifist: It takes them hours of meditation to come to the decision to fight and when they finally do fight, they still prefer intimidation rather direct combat.

Tropes associated with the Wood Forgers
- Arch-Enemy: To Viragor.
- Art Initiates Life: Gami's paper beasts animate, move and employ Breath Weapons. Zigg can paint a vessel with his brush to capture and contain evil spirits, or paint a miniature animation of Viragor. Snips can create self-propelling pinwheels, snowflake blizzards and people-sized cages.
- Breath Weapon: Gami twice folds a giant animate paper dragon, which alternately breathes a powerful wind or purple bursts of fire.
- In Harmony with Nature: They use their wood forging to defend the forest against Viragor, employing a paper mill to produce their supplies. Which they do by unsustainable clear-cutting with no replanting, provoking the ire of Viragor.
- Macross Missile Massacre: One of Zigg's attacks is basically the paper version of this.
- Paper Master: Zigg favors calligraphy, Gami folded animals, and Snips papercraft.
- Paper Talisman: Used by Zigg, complete with Magical Incantation "Begone, evil spirits..."
- Protectorate: The Forest of Magi Oar.
- Punny Name: Zigg is from "zig-zag" Gami from "origami" and Snips from the action of a scissors
- The Voiceless: Snips and Gami do not speak, allowing Zigg to do all the talking.

A monstrous bird who inhabits the Forest of Magi Oar and antagonizes those who travel and live within it.
Tropes associated with Viragor:
- Arch-Enemy: To the Wood Forgers.
- Dark Is Not Evil: While he looks very intimidating, he isn't nearly as mean as he looks. He even apologizes to Cheetara by replacing the staff he broke when he tried to eat her.
- Expy: In the Princess Mononoke - like plot of "The Forest of Magi Oar", he's closest to Moro. His warming to Lion-O also reflects this.
- Giant Flyer: He's a giant bird.
- Good Is Not Nice: Has no compunction about threatening the lives of those he sees as invaders, or inflicting massive amounts of property damage on an inhabited building. He also takes a shot at eating Cheetara, just missing her but breaking her staff in the process.
- I'm a Humanitarian: Played with. He's certainly big enough to eat people, and has a good try at eating Cheetara, but his eating people without provocation seems to be another Wood Forger lie.Lion-O: You're going to eat me, aren't you?Viragor: I'm thinking about it. He doesn't, instead telling his story to Lion-O.
- In Harmony with Nature: Very much resents perceived invasion of and damage to "his" forest.
- Nature Spirit: Stubbornly wages war on the Wood Forgers and demands they leave the Forest.
- Not Evil, Just Misunderstood: He is very confrontational at first, but mellows out quickly enough.
- Voiced by: Robin Atkin Downes

Tropes associated with Javan

- Daddy Had a Good Reason for Abandoning You: Either abandon his son, or kill him. He made the right call.
- Dead All Along: It's revealed that every member of the Tiger Tribe had been trapped in a state of undeath because of Javan's deception of the Ancient Spirits of Evil. Once the curse is broken by Tygra forgiving his father, the tigers are all able to fade from existence in peace.
- Meaningful Name: His name refers to the Javan Tiger, an extinct subspecies of tiger that was native to the Indonesian island of Java which makes sense when it's revealed that he and the rest of his clan have been Dead All Along.
- Papa Wolf: The assassins who try killing Tygra, learn this the hard way.
- Pride: Self-aware enough to realize that the Tiger Clan's pride has always been its greatest flaw. Even he didn't fully overcome it — he tries to break his son's heart to drive him away because he's too ashamed to admit the Awful Truth.
- Voiced by: Jim Cummings

- Death by Childbirth: She did not survive giving birth to Lion-O.
- The High Queen: She is beautiful and benevolent.
- Huge Guy, Tiny Girl: She's quite petite when compared to Claudus, who looks enormous when standing by her side. Her delicate build and petite stature may have contributed to her complications and death in childbirth.

- Missing Mom: It is revealed in "Native Son" that we don't see her in present day because she died giving birth to Lion-O.

- Papa Wolf: The father goes out making sure Wilykit and Wilykat make it to safety.

- Noble Bigot: Despite thinking ill of Panthro for presumably abandoning him to the arena, and thinking that cats in general have no honor, he nonetheless greets Panthro as a friend and lets the ThunderCats stay in his city. Later, when Pumyra refuses to finish off Lion-O even when threatened with death, he even agrees to release Pumyra from the arena.
- Rags to Riches: Started out as a lowly gladiator fighting in the arena. By the time the ThunderCats meet him, he's the man in charge of the whole spectacle!

- The Fagin: Tookit recruits children to steal for him.
- It May Help You on Your Quest/You Will Know What to Do: His kleptovoyance in a nutshell, leading him to steal seemingly worthless trinkets that soon after prove beneficial to him in some way.
- He incorrectly believes this applies to people too, believing that his frequent run-ins with the Thunderkittens are a sign that they will help him pull off the biggest heist in his life. Instead, they free the urchins he trapped in a life of crime by siccing a guard on him and stealing his Forever Bag. The only thing his kleptovoyance lead him to steal in this episode was a hairpin that allows him to break out of his cell at the end.
- Karma Houdini: He avoids getting in trouble for manipulating children into helping him steal stuff. While he's eventually caught in the episode "The Forever Bag" and forced to fight in The Pit, he pulls out a pin he stole earlier with the intent of using it to pick his cell's lock, indicating that his escape is imminent.
- Loveable Rogue: Manipulative and deceptive nature aside, he's not all that malicious.
