The Mighty Thor (Caveman/Neanderthal Transformation)

Thanks to Ogrebear for finding issue 231, pubished in 1975. A seance gone wrong when one of the attendees is possessed by and transformed into a Neanderthal who calls himself "Armak, the First Man."

Alas, Armak gets defeated:

"Beast Branding" & "Report Corruption" (Crocodile and Caveman Transformations)

Apuleius here, bringing you two commercials. 

"Beast Branding" is a recent Spanish-language ad for ampm. I initially assumed this was a wolfman, but a reader points out it's more likely a caveman. (Thanks to Joey Liverwurst for the clip.)

Next, an ad from Hong Kong, made in 1994 to promote the Independent Commission Against Corruption. The claymation croc is well done!

Primal (Muscle Growth)

This is co-editor Kumaguma, bringing you a transformation from the new Gendy Tartakovsky cartoon Primal, discovered by  Musclelover on our blog's Discord server. In the fifth episode, Spear the caveman and the tyrannosaurus Fang are captured by apes and made to fight with warriors in an arena. The shaman that surveys the combat gives the apes a drop of a potion that increases their muscles and aggression. Spear manages to free himself and drink the entire potion, hulking out against his captors:

"Tales From the Crypt" and "The Flash" (Monster, Muscle Growth, and Caveman Transformations)

Two more comics to enjoy. Our first selection is from issue 5 of Tales From the Crypt--not the original classic comic from the 1950s, but rather the 2008 revival of the series. In the story "Kid Tested, Mother Approved!" we meet Jimmy, a boy who doesn't feel like eating his usual breakfast, much to the alarm of his parents and teachers. They sit him down and try forcing him to eat, which just annoys him. When the principal's back is turned...

Evidentally the cereal kept Jimmy from turning into a monster grown-up. Order is eventually restored after Jimmy gets tranquilized. On the final page Jimmy is at a new school, but trouble is in the air:

Moving on...our second item is from The Flash #243, but it's actually a back-up story starring Green Lantern, who runs into some nasty aliens with de-evolutionary powers. Soon he finds himself becoming the Green Caveman:

Transformation Round-Up (Various Transformations)

All of the following transformations were discovered by Daymon, our resident TF sleuth-hound.

A gnarly lion-monster transformation from the anime Flame of Recca (episode 24). The character gets even more monstery in the next episode.

A caveman TF from Totally Spies (Season 3, Episode 23: "Head Shrinker Much?").

Here's a cartoon I remember from growing up in the 80s: Tiger Sharks, which ran as part of an anthology program called the Comic Strip. The characters were humans who could turn into marine animal hybrids. In this clip from the first episode you see Walro going walrus, and then, after a few seconds, Mako becoming a man-shark. In the next episode, Lorca turns into--well, you can guess from the name.

From the first episode of another 80s show, Galaxy High School, a bulldog turns into a two-legged dog-man.

In episode 24 of The Men in Black cartoon, Agent K turns into a well-muscled rock humanoid at the 6:05 mark.

More for the muscle-growth fans: a bulking-up from the film Heavy Metal.

And one more treat for muscle-growth fans--a scene from the 2006 cartoon Biker Mice From Mars (Season 4, episode 3; "The British Invasion"), wherein mouse-man Stoker transforms into a feral rat-like monster when exposed to sunlight. The scene begins at 1:06 and continues past the opening credits, with a reversion at 11:08.

A humanoid-dragon morph from the manga Kajika by Akira Toriyama.

A dinosaurian TF from the manga Animal X (Vol.01 Ch.02 "Aragami no Ichizoku").

No update would be complete without a NSFW entry, and this one is from a doujinshi called Saimin Sennouen, which has two transformation scenes. In the first (starting here) a man has a bear mask placed on his head, which transforms him into a metaphorical bear and then a literal one. In the other story, a guy is turned into a Minotaur/bull (the artwork's by Nojo).

Daymon was also curious if anyone knew the source anime of a certain muscle-growth gif.

If you enjoyed these clips and scans (you'd be crazy if you didn't!) please thank Daymon!

Art Roundup (Ape and Various Transformations)

Two recent art finds, both NSFW.

A while back we reported on the transformation artwork of Navetsea. That artist has completed a new transformation sequence involving devolution, one of my favorite themes. An amorous couple start making out, only to get devolved into dumb, horny cavepeople. The sequence is available at the site "Hentai Foundry," and you might have to register in order to see it. The images are located within this gallery.

Our friend Externica recently informed us of a large gallery of transformation pictures (labeled 猪竹の) on Pixiv, a Japanese image-hosting site. A couple of things you should know: the artist does not have a good scanner, and his work is rather sketchy, though it does have vitality and a great love of transformation. Also, since it's adult-themed, you'll need to register with Pixiv to see the gallery (Externica reports that Pixiv might give some email addresses trouble). Lastly, many of the pictures are sequences loaded into one file, and you have to keep scrolling to load the next few images. But  it's worth it--many of the pictures involve demon and werewolf transformations, and there are also some involving leopards, kappa, bulls, dragons, and even plants. See them here.

Manzanita Sol (Evolution Transformation)

Manzanita Sol is a fruit-flavored soft drink sold in Spain or Latin America, and this amusing commercial features a fish so desperate for a gulp that he evolves out of his tank and into human form, turning into a half-dozen species along the way. It's bad science, since hardly any of the creatures he evolves into are human  ancestors, but I wouldn't mind seeing more commercials of animals turning into naked men.
