This Hanna-Barbera series was another of the studio's 1960s action lineup. Mighty Mightor featured the adventures of Mightor and his pet, Tog, in a prehistoric setting. Mightor is in reality Tor, who received a magic club from resucing an old hermit from a rampaging dinosaur. He need only raise the club and yell "Mightor" to change into a prehistoric superhero complete with flight and Super Strength.
In his original series, Mightor shared a half hour with Moby Dick.
- Action Series: Another of several produced by Hanna-Barbera in the 1960s.
- Aside Glance: Ork gives many.
- Clark Kenting: To an extreme level, Mightor is Tor....Tor always disappears when Mightor appears. Tor has a pet dinosaur named Tog, Mightor has a pet dinosaur named Tog who can breathe fire. While this has a prehistoric setting it is unreal no one ever figured out this "secret".
- Crossover: With Space Ghost in his Council of Doom arc. Space Ghost is accidentally zapped into the past and is saved by Mightor and Tog.
- Damsel in Distress: Sheera is kidnapped multiple times by the villains.
- Distressed Dude: So is Little Rok, and sometimes even Tor himself.
- Dinosaurs Are Dragons: Tog has wings like a dragon, which no dinosaur (birds included) is known to sport, and gets a fire-breathing upgrade as part of the club's power.
- Domesticated Dinosaurs: Tog is a pretty tame one. Ork the Dodo and Bollo the Mammoth could also be seen as examples.
- Everything Is Better With Dinosaurs: In a way, Tog is this trope, but bad guy dinosaurs avert this.
- Evil Laugh: Almost all of the villains had one.
- Evil Twin: In "Battle of the Mightors", Ogar returns disguised as Mightor to try to trick the villagers into thinking that Mightor has gone evil.
- Expy: Mightor is a rather blatant expy of The Mighty Thor, due to the show having originally been intended to be a Thor series. Magic weapon turns an ordinary harmless person into a hero of mythological proportions? It's all there.
- Flying Brick: Mightor's primary powerset.
- Handsome Heroic Caveman: The eponymous character was a prehistoric superhero with an idealized Captain Marvel-ish physique. He is the Older Alter Ego for teenage caveman Tor (no relation to the comic book character Tor), who, along with his his girlfriend Sheera, also fit this trope.
- Heroes Want Redheads: Tor likes Sheera but she only cares about Mightor, who of course happens to be Tor.
- Irisless Eye Mask Of Mystery: Mightor's mask does this, but in this case his transformation is already magical.
- Kid Sidekick: Little Rok dreams of being this, and tries but usually fails.
- The Load: Little Rok is this so much that Mightor himself even muses, "Oh no, not Little Rok again," in some episodes.
- Monster of the Week: Some of Mightor's enemies were this.
- Non-Human Sidekick: Tog for Mightor/Tor, Ork for Little Rok, Bollo for Sheera.
- Origin Story: As detailed after the opening theme, Tor saves an ancient hermit, who gives him a club that allows him to become Mightor and allows Tog to breathe fire.
- Rogues Gallery: Rogg and The Stone Men, Gorg and Brog the Mountain Men, The Serpent Queen, etc.
- Superhero: Mightor is a very early example for his time period.
- Super Strength: Good God, is Mightor damn strong. At one point he lifts up a whole island with people on it all by himself.
- Tagalong Kid: Little Rock is this.
- Three Shorts: The show ran on this format. There were two Mightor cartoons with one Moby Dick cartoon in the middle.
- Transformation Sequence: While not a major one, Tor has one where he raises the club and becomes Mightor, who flies off. The backgrounds change based on the episode, but it is the same sequence.
