Lord of The ThunderCats.---- Tropes associated with Lion-O:
- The Ace: Invoked in a mini-series arc: To officially claim his title of Lord of the ThunderCats, he has to beat each of them in a contest at whatever they're best at. He manages it by cleverness or exploiting a weakness. (For instance, Cheetara can only maintain Super Speed over a short distance race, not a marathon.)
- Bare Your Midriff: His armour has a conspicuous opening for his abs.
- Curious As A Kitten: Almost as bad as The Thunder Kittens.
- Empathic Weapon: The Sword of Omens.
- Green Lantern Ring: The Sword of Omens again.
- The Hero: Main Good guy.
- Idiot Hero: Well, he is very naive due to being a kid in an adult's body.
- The Leader: First a Type IV; he's only the leader because he's the prince. Later matures into a type II, becoming responsible and taking his role more seriously.
- Magical Incantation: The Sword of Omens has two.
- "Thunder, Thunder, Thunder...Thunder Cat HO!"
- "Sword Of Omens, give me sight beyond sight!"
- Palantir Ploy: "Sword Of Omens, give me sight beyond sight!"
- Plot-Relevant Age-Up
- Red-Headed Hero
- Younger than They Look: Lion-O is actually the youngest member of the cast. The only reason he looks so old is that his suspension pod broke during the escape from Thundera, causing him to age in his sleep while the others all remained the same. He spends most of the (early) series learning to be a mature and responsible leader.
Voiced by Earle Hyman---- Tropes associated with Panthro:
- Bald of Awesome/Furry Baldness
- The Big Guy: Panthro is a Class V hands down. Not only the physically strongest member of the team, but he also built every piece of technology the ThunderCats use, starting with the Thundertank.
- Practically spelled out in the first episode, when the Mutants attack:"Hahaha! If you guys were as mean as you were ugly..." *effortlessly blocks and crushes a Mutant's mace with one hand* "...then maybe you'd be trouble!"
- Epic Flail: His battle sticks, aka nunchucks, which he could load with tricks like high pressure bubbles... or compact flamethrowers for a fight.
- Gadgeteer Genius: He was able to build the Thundertank using components that he salvaged from the ThunderCats' wrecked ship.
- Genius Bruiser
- Mr. Fixit
- Why Did It Have to Be Snakes?: He's afraid of bats, and in one episode admits that he hates spiders, too.
Voiced by Peter Newman---- Tropes associated with Tygra:
- Designated Victim: If someone has to get mind-controlled, captured, or otherwise endangered, it's probably going to be him.
- Invisibility Cloak: His whip.
- The Lancer
- Master of Illusion: It Only Works Once.
- The Smart Guy
- Weaksauce Weakness: Early on, he couldn't swim unless he was invisible (ironically, tigers are one of the few cats who don't hate water).
- Whip It Good
Voiced by Lynne Lipton---- Tropes associated with Cheetara:
- Action Girl
- Blessed with Suck: She specifically calls her sixth sense a curse, as using it tends to nearly kill her.

- Fragile Speedster
- Psychic Powers
- Simple Staff
- Super Speed
- Team Mom
The Thunder Kittens: WilyKat & WilyKitEdit
WilyKat voiced by Peter Newman, WilyKit voiced by Lynne Lipton---- Tropes associated with the Thunder Kittens:
- Bratty Half Pints: Frequently.
- Curious as a Kitten: Ancient tombs, Death Trap-filled towers, spooky caves, whatever. If it's ominous and likely to be dangerous, they're going to poke around in it.
- Genki Girl: Wilykit
- Idiot Ball: The plot would occasionally get started because they decided it'd be fun to, say, open up an ancient tomb or "borrow" the others' weapons without permission.
- Keet: Wilykat
- Parental Abandonment: No explanation is ever given for who the twins' parents were or what happened to them.
- Sibling Seniority Squabble: In the Wildstorm comics, at least. Wilykat does not like being called "Little Brother."
- They Are All Grown Up: In the comic miniseries ThunderCats: The Return. Puberty was very good to them. (Also Fetish Fuel.)
- Tagalong Kids
- Tricksters: Most of their weapons and tactics rely on misdirection, blinding opponents, etc.
Snarf (AKA Osbert)Edit
Voiced by Bob McFadden---- Tropes associated with Snarf:
- Embarrassing First Name: Snarf hates his real name and berates Snarfer any time he uses it.
- Incorruptible Pure Pureness: He is immune to most forms of mind control and possession. Jaga explains that his species is incapable of having evil in their hearts.
- Lovable Coward
- Pokémon Speak (since he doesn't use his real name)
- Team Pet
Voiced by Earl Hammond---- Tropes associated with Jaga:
- Badass Grandpa
- Big Damn Heroes: As a ghost, he saved the day because he was the only character who could hit Grune The Destroyer.
- Cincinnatus: Lion-O's father was blinded in a battle against the Mutants, so he turned power over to Jaga until Lion-O would be ready to claim the title of Lord of the ThunderCats.
- Cool Old Guy
- Heroes Prefer Swords: If not the Sword of Omens then a regular long sword.
- The Mentor/The Obi-Wan
- Our Ghosts Are Different

Voiced by Doug Preis---- Tropes associated with Lynx-O:

- Cool Old Guy
- Disability Superpower: He seems to have a radar sense similar to Dare Devil
- Eyes Always Shut: Due to blindness via burned eyes.
- Handicapped Bad Ass: Despite being blind, he fights (and often wins) without a weapon and he can even fly a plane using a special board and his radar sense!
- Pressure Point: Part of his fighting style.
- Team Dad: Due to being the oldest. Moreso with Pumyra and Bengali than with the rest of the Cats.
Voiced by Gerrianne Raphael---- Tropes associated with Pumyra:
- Affirmative Action Girl
- Animal Eyes: Subverted, she's the only Thundercat with round, human-like pupils
- The Chick: Even more than Cheetarah
- In a Single Bound
- The Medic
- Out of Focus: She appears in the fewest number of episodes and disappeared almost completely near the end.
- Skunk Stripe
- Technical Pacifist
- Weapon of Choice: A sling, possibly combined with Whip It Good.
Voiced by Peter Newman---- Tropes associated with Bengali:
- The Blacksmith: He's one of the few individuals capable of repairing the Sword of Omens.
- Drop the Hammer
- Hot-Blooded: After Lion-O spends the first half of the series learning to keep a cool head.
- Unrelated Brothers: He and Tygra often refer to each other as brothers, probably because they are both tiger-based Thundarians.
Voiced by Peter Newman---- Tropes associated with Hachiman:
- Absurdly Sharp Blade: As Monkian describes, "Did you see that!? He chopped through solid stone!"
- Empathic Weapon: His katana, "Thundercutter," which will not come out of its scabbard if Hachiman tries to use it to perform an act of evil (like say, any order by Mumm-Ra).
- Everything's Better With Samurai
- Honor Before Reason: Oh sure, just keep hacking away at the narrow bridge over the near-Bottomless Pit you and Lion-O are both standing on until he agrees to backtrack and let you pass. You might both fall to your death, but at least you'll maintain your pride as a samurai! (Not that Lion-O was behaving any better at the time, mind you.)
- Horrible Judge of Character: Come on, he was fooled by Mumm-Ra twice even though he wasn't using any disguises or anything.
- Katanas Are Just Better
Voiced by Lynne LiptonQueen of the Warrior Maidens.---- Tropes associated with Queen Willa:
- Does Not Like Shoes: Like the rest of the Warrior Maidens, she goes barefoot.
- The Power of Acting: She was once able to trick the bad guys into thinking she had gone over to The Dark Side, so she could surprise them. It was quite convincing.

Mumm-Ra Voiced By Earl HammondEdit

- Achilles' Heel: He can only leave his sarcophagus for 24 hours at a time.
- As Long as There Is Evil: "As long as evil exists, Mumm-Ra lives!"
- Bad Boss
- Big Bad
- By the Power of Grayskull!: (Villain variant) "Ancient Spirits of Evil, transform this decayed form into Mumm-Ra, the Ever... LIVING!!!"

- Chronic Backstabbing Disorder
- Evil Laugh
- Evil Plan
- Evil Sorcerer
- Large Ham
- Let's You and Him Fight: Invokes this a lot.
- Master of Disguise: Most of his plots involve disguising himself as an innocent or an ally and luring the ThunderCats into a trap.
- One-Winged Angel: By invoking the Ancient Spirits of Evil, he can assume the form of Mumm-Ra the Everliving, which is far more physically adept than Mumm-Ra is. He also turns into an even-more powerful version called Mumm-Ra the Allpowerful in one episode.
- Orcus on His Throne: Spends most of his time lurking in his tomb in his pyramid. Justified because he can only survive outside of his coffin for 24 hours and he needs to keep the chamber where he invokes the Ancient Spirits of Evil protected, lest someone steal their power from him.
- Our Liches Are Different: He looks more like a mummy and can transform into more life-like super-powered form
- Pet the Dog: Toward his actual pet dog, Maa-Mutt. He's genuinely horrified when Maa-Mutt is exiled in "The Last Day", and at the end of "Maa-Mutt's Confusion" he frantically digs him out of the wreckage of his destroyed Weapon of Mass Destruction and apologizes for abusing him earlier.
- Palantir Ploy: His pool can show images at any location.
- Time Abyss: "I remember when this was first Earth."
- Voluntary Shapeshifting
- Weaksauce Weakness: His own reflection.

The Mutants of Plun-DarrEdit
Ssslithe Bob McfaddenEdit

- The Starscream: Every plot with Vultureman involved him trying to wrest control of the Mutants from Ssslithe.

Ratar-O Bob McfaddenEdit
Tropes associated with Ratar-O:
- Big Bad
- Tyrant Takes the Helm: He steals command of the Mutants from Ssslithe, much to the latter's consternation, and starts running the gang like a Drill Sergeant Nasty. The only problem? Under Ratar-O the Mutants actually start winning.
