ThunderCats (1985 series)/YMMV

• Anvilicious – Like a lot of 80s cartoon series, a lot of this show's episodes were focused on some specific "moral", and weren't very subtle about it.
  • Somewhat justified in that Lion-O needed to be taught these lessons and quickly so he could become an effective leader.
  • And sometimes a little Narmy, like in one episode where Tigra practically looks at the camera when stating the how laws that go unobeyed "are just words." You know, rather than rescue their leader from a mob of Brainwashed and Crazy natives.
• Ass Pull – Some characters (including Lion-O) somehow get massive powers on convenient moments, like Cheetara's psychic Limit Break.
• Does This Remind You of Anything? – The Sword of Omens, which lengthens dramatically when it's time for action, but needs a firm hand on its grip and verbal encouragement... yeah...
• Ensemble Darkhorse: Panthro is regarded by many fans as their favorite.
  • Tygra also garnered some decent popularity, especially with girls watching the show. He was the Thundercat besides Lion-O to get a new figure in Bandai's line of classic Thundercats. Many of his fans were upset by the changes made to his personality in the 2011 reboot.
  • Pumyra was under-utilized because the producers often didn't know just what to do with her, but many fans claim her as their favorite character. The anticipation surrounding her appearance in the 2011 reboot is insane.
• Hilarious in Hindsight - Early in the second season of the original 80s show, Lynx-O tells Lion-O that his voice sounds just like his father's. In the 2011 remake, Larry Kenny, Lion-O's original VA, will be the VA for Lion-O's father, Claudus.
• Large Ham – Both Lion-O and Mumm-Ra are pretty damn dramatic and larger than life
  • Everyone. The villains, the heroes, even the side characters. Everyone has dramatic pauses and overwrought enunciation.
• Nightmare Fuel – As creepy as Mumm-Ra was, the Living Ooze was definitely the scariest thing on the show.
  • A nightmare-tastic episode has Lion-O was trapped in some creepy catacombs with these Morlock-esque creepers with gigantic eyes, speaking about how they had been driven out of the world by people being too terrified of what was written in their books.
• The Scrappy – The entire Snarf race
  • Since they're supposed to be "normal" where they come from, Alien Scrappy also.
  • Special mention should go to Snarfer, who was just downright annoying. Also the three new Thundercats from season 2 weren't very well-received.
    • Judging by the new animated trailer, they may be attempting to rescue Snarf from the Scrappy heap.
  • The character probably most deserving of fans' hatred is Captain Bragg, who made the Mutants and Lunatacs look like a bunch of chumps and put them on a train out of the series. He gets away with hypnotizing WilyKat and tricking him into helping him and doesn't get punished for it. Bragg doesn't even have any real coolness to him to make up for it, he's just an old circus ringleader with a talking crow.
• Villain Ball – As an 80's Children's show, it's to be expected. One notable incident had to do with Mumm-Ra getting an Orb which quadrupled his power. The Ancient Spirits of Evil felt threatened by it with the prospect of being replaced, so they closed the pyramid to him. They couldn't do this after he finally killed off the Thundercats?
  • In another, The Ancient Spirits of Evil gave him 24 hours to finally kill the Thundercats, so he decided to do just that. Just as he was about to finish Lion-O off, they declared his time was up and whisked him away for punishment. If they had waited a few more seconds, Mumm-Ra would have actually won.
    • Well, they are evil, you know...
• What Do You Mean It's Not Awesome? – For an '80s kids cartoon, this show was remarkably well-thought out and inventive. Cat-people? Humans love cats. Homeworld destroyed in a fiery explosion? Humans love fiery explosions. Also, it's the Superman angle that Biker Mice From Mars used later. Why are these few main characters the only survivors? There were more, but the mutants killed all of them by shooting down every other refugee ship in the first episode. The Crowning Moment of Awesome for the writers is probably Mumm-Ra himself. Yes, he's an often comically ineffective '80s cartoon villain. But see As Long as There Is Evil above. When you're a kid and you realize this means he can never be slain, well...
