It should be obvious to everyone that Inferior Five 3 (July/Aug 67) has a Tarzan take off, just from the cover, by Bridwell and Sekowsky.
The Inferior Five head to Gravestone Castle to seek out Darwin of the Apes, who lives like a British gentleman when not adventuring in Africa. We get to see the Inferiplane in this one, a particularly dangerous looking mode of transportation, which nevertheless functions well enough to get the heroes where they need to go.
Darwin gets some comedic byplay with his version of Jane, and his relationship with animals, as he travels to Africa with Merryman, Blimp, White Feather, Dumb Bunny and Awkwardman in search of a missing doctor, who was inspired by Dr. Livingstone, I presume.
Oh, come on, I get to make jokes when I write about this series.
Easily my favourite line in the story comes when they reach a city that was a lost colony of Atlantis, a civilzation older than the Egyptians. When Merryman comments that he has never heard of them, Darwin replies that Africa is full of such places, "thick as fleas."
In the city, the men all look ape-like, while the woman are all super models. It's pretty much what one would expect from a strip that contains a character like Dumb Bunny, but I did appreciate the footnote just blatantly stating that the writer likes attractive women. May as well be honest about it. The story does resolve properly, as they find the missing doctor and bring him back home.
