The Guyver: Out of Control (Demon/Monster Transformations)

Thanks again to Andréssaurio Rex for recommending this anime feature from 1986. Two transformations occur at 6:32 and 6:58, and this video is cued to the first. There's also a third TF at 22:31. 

Tales of the Teenage Mutant Ninja Turtles (Blob/Monster Transformation)

Thanks to Andréssaurio Rex for recommending these scenes from episode 12 of the second season. They show the villain Roderick Underwood turning into "Muckman." The clip has been assembled from several discontinous scenes, so apologies if it's a bit choppy:

 

John Carpenter's Toxic Commando (Monster Transformation)

Here's the animated trailer for John Carpenter's Toxic Commando, "an upcoming ‘80s-inspired action-horror FPS game." Thanks again to Andréssaurio Rex!

Robotomy (Monster Transformation)

A robot somehow turns into a monster in the ninth episode of this cartoon. Thanks again to Andréssaurio Rex for the recommendation.

"Monkey Wrench" & "Primal" (Muscle Growth)

 From episode 4 of the webseries: After Beebs refuses Campion Ajax's offer and shrugs him off, the latter grows with wrath:

And continuing with the monstrous-muscle-growth theme, here's a scene of a male dinosaur hulking up, from Primal (season 3, ep. 10). Thanks to Mr. Rex for the recommendation.

"Biker Mice From Mars" & "Acme Arsenal" (Muscle Growth and Monster Transformations)

Andréssaurio Rex suggested featuring the muscle growth scenes from this '90s cartoon. Luckily for lazy people like myself, The Male Muscle Growth Archives has already assembled a compilation of them! Go directly to the video's description for the episode titles. 

Mr. Rex also recommended this short cutscene from the video game Looney Tunes: Acme Arsenal, which also features muscle growth and monsterism, so I've included it as a bonus:

Blood+ and Blood-C (Monster Transformations)

Our thanks to Andréssaurio Rex for these links. The first scene is from episode 49 of Blood+ (if the cue doesn't work, go to 6:36): 

The second is from episode 12 of its follow-up, Blood-C:

Superman: The Animated Series (Monster Transformation)

In episode 10 of this classic cartoon, a villain known as "The Preserver" reveals his true form. Thanks to Andréssaurio Rex for the link.

The Mighty Nein (Monster and Crow Transformations)

Welcome to the Christmas update! Apologies for the long wait, but now you can celebrate the holidays with 39 new posts. Thanks as always to everyone who sent in recommendations, and we hope you have a Happy New Year. May we enjoy for plenty more transformations in 2026!

Post-Script: Several readers notified us that in some of the comic posts there were thumbnails that didn't enlarge when clicked. We have now fixed them. But if you encounter any other issues, let us know. Now on with the update...

Thanks to the many people who recommended episode 3 from The Mighty Nein. During a circus show the Devil Toad goes berserk and shoots out mutagenic needles that transform anyone hit into his monstrous thralls. 

Three men are shown transforming onscreen--a member of the audience, an acrobat, and the ringmaster: 

But there's more! Andréssaurio Rex informed us of a crow transformation in the most recent episode (eight), and here it is! 

Dungeons & Dragons: Mindbreaker (Monster Transformation)

Thanks to Ggwell from our Discord server for recommending issue three, with its parasite-monster transformation:

 

Solar Opposites (Monster, Muscle Growth, and Transgender Transformations)

Thanks to Andréssaurio Rex for finding these!

From episode four of season six: Korvo (one of the main characters) is having an argument with his daughter Jesse, who wants to be a dad (after playacting as one and enjoying the perks). She gets accidentally doused with a chemical that turns her into a literal Dad:

 

From episode 10 of season six: a monster who feeds on negativity gets an overload, causing him to grow too much. Shortly afterward, "The Pupa" turns from a grub into a snake-like monster:

Monster Raban (Kaiju/Lizard Monster Transformation)

Thanks to Dinonator for recommending this manga from 1958. A scientist comes across his rival, who has been reduced to skin and bones by poison, and injects him with a vial of Godzilla's blood, hoping it will be lethal. Instead it turns his rival into a giant lizard.  

 

Project Nemesis (Monster Transformation)

Thanks to Andréssaurio Rex for recommending this six-issue limited series, which shows the bad guy gradually transforming into a Doomsday-like monster. The first images are from issue three:

 

Continuing into issue five:

And issue six:

 

From what I can tell, the villain survives and transforms into his final form, pictured below, but off-panel.

Fire and Stone: Prometheus & Aliens vs. Predator (Alien and Monster Transformations)

Thanks once more to Andréssaurio Rex for suggesting this crossover comic series, set in the Alien vs. Predator franchise. (Spoiler warning.)

In Prometheus: Fire and Stone #02, the scientist Francis, who is dying of cancer, convinces Elden, an android, to be injected with a mysterious alien "accelerant," in order to test its possible regenerative effects:

Issue three finds Elden, now a mix of machine and alien, resenting his new form:

 In issue four Elden sets off into space to get revenge on Francis:

 

In Alien vs. Predator: Fire and Stone #01 Elden works with the xenomorphs to corner Elden:

 

Issue 2 finds Elden fighting and biting a Predator, who undergoes a transformation of his own:

Issue 3 opens Elden getting attacked and bitten by Xenomorphs, causing him to mutate again:

Francis, hoping to cure his cancer, steals some of Elden's blood and injects himself with it. Of course a hideous monster transformation ensues:

Issue 4 opens with the still-transforming Francis getting attacked by the mutated Predator and rescued by Elden. The two reconcile, only for Francis to start dying--the accelerant has sped up his demise:

In the final chapter of the crossover, Prometheus: Fire and Stone—Omega, Elden crash lands on an alien planet and merges into a living mountain of alien flesh:
