Voices: John Vernon (Namor), Bernard Cowan (Narrator), Peg Dixson (Lady Dorma), (Mrs. B), (Freddie), (Police Officer), (Police Captain), (Leonard McKenzie), (Sailor), (Princess Fen), (King Thakorr).
Plot: Namor finally meets the mysterious old woman who has been stalking him only to reveal that she is his grandmother! She tells the Sub-Mariner the tale of how his parents, a human and an Atlantian, met and bore a son.
Review (Warning! Spoilers!): This is Namor's origin. Since he was born with his powers (he is considered a hybrid, not a mutant, by the way) the story revolves around his parents.
Although they don't call him by name, his father is Captain Leonard McKenzie who falls in love with Princess Fen from Atlantis. The story told is pretty accurate to the original comic books except that Namor's parents don't die.
This segment of The Marvel Super Heroes is quite different in that they seem to be forging their own path for the Sub-Mariner. At the end of the episode Namor declares that he is proud of his Earthly heritage, something that he would never do in the comics.
My guess is that Grantray-Lawrence Animation wanted to play down the 'anti-hero' aspect of the Sub-Mariner and create a more likable character. We'll see how that plays out in the episodes to come.
