The Mighty Thor vs. The Mighty Mightor

And the technicolor version...I'm sure everyone knows who Thor is but here it goes anyway...
The character first appears in Journey into Mystery #83 (August 1962) and was created by editor-plotter Stan Lee, scripter Larry Lieber, and penciller Jack Kirby. Debuting in the Silver Age of comic books, the character is based on the Thor of Norse mythology. Thor's father Odin decides his son needs to be taught humility and consequently places Thor (without memories of godhood) into the body and memories of an existing, partially disabled human medical student, Donald Blake. Like all Asgardians, Thor is not truly immortal but relies upon periodic consumption of the Golden Apples of Idunn to sustain his lifespan, which to date has lasted many millennia. Being the son of Odin and the elder goddess Gaea, the character is physically the strongest of the Norse gods.
The Mighty Mightor is a science fiction animated series created by Alex Toth for Hanna-Barbera Productions, which ran on CBS from 1967 to 1969. One day, while on a hunting trip, a teenage caveman named Tor, along with his winged pet dinosaur Tog, rescue an old man who, as a reward, gives Tor a magical club. When Tor raises his club to the sky, he transforms into the masked and muscular Mightor, a prehistoric superhero very much in the Space Ghost mold who is super-strong and can fly and fire ray blasts from his club.
