"Spider-Man '94" & "Adventures Into the Unknown" (Age Progression and Age Regression)

Issue two of Spider-Man '94, published in 2025, features the age progression of Peter Parker clone Kaine, who goes from test-tube baby to adult:

And for some age regression, here's a story from Adventures Into the Unknown #117, published in 1960. It's only five pages, so I've included all of it:

Assassination Classroom, Wai Wai Quick Noodles, and The Extant (Monster and Alien , and Age Progression)

My thanks to Ian Ricky for finding and uploading the following clips. 

From the Japanese film Assassination Classroom: Graduation (2016), Yanagisawa (Hiroki Narimiya) injects himself with artificial tentacles and turns into a big monster:

Next, a human reveals his true alien self in this commercial for Wai Wai Quick Noodles:

And for those who'd like to see even more skin-shedding, here's an age progression scene from The Extant (S02E03):

Tussen Jou en Mij, Poison Kiss, & Quickie 8 (Age Regression and Progression)

These three items all involve age transformations. First, an anonymous reader recommends the Dutch music video "Tussen Jou en Mij," which has some animated age regression toward the end:

Next, Ian Ricky has found an age progresion scene from the live action Chinese film Poison Kiss (1992, 毒吻). Ian provides a description: "A son was born from a chemical factory worker couple who died. The son has highly poisonous saliva, but also suffers from gigantism due to environmental pollution and grows up rapidly whenever there's a thunderstorm. He goes from a baby to a toddler, a child, and a young man. The surface of his body grows extremely poisonous and kills whatever touches it. In the end, he's struck by lightning and disappears..."

Concluding this post is a link to "Quickie 8" by AgeGrowthFictions, who creates high quality age progression animation. Before you click, be aware that this video is NSFW. Watch it here! The artist also has a trailer for his newest work, which involves AP and a demon TF.

Inside Job (Age Regression and Progression)

In episode 12 ("Whoas-Feratu") Randal tries to make a movie to outshine Keanu Reeves while wooing his ex-wife. During production, he take a youth serum but ages down to a baby. He turns back to normal in time to save his daughter and former lover from a legion of vampires:

Muscle Growth Round-Up (Muscle Growth, Monster, and Centaur Transformations)

Our thanks to Ian Ricky for providing all but one of these clips!

From the Hong Kong comedy film Tricky Brains (1991): Chi Man Kit (Andy Lau) is seized by villains and forced to drink a whole bottle of "irresistible aphrodisiac." The overdose causes him to become incredibly strong and muscular:

From the Japanese film Kaiju Mono (2016): to combat a kaiju, Dr Saigo injects his assistant Nitta with a formula that turns him into a muscular giant. After an unsuccessful battle with the kaiju, Dr. Saig injects more formula into Nitta, tuning him into an older and more sinister giant.

Ian R. has assembled a compilation of scenes from episodes 91, 112, 113, 114, 115, 117, 120, and 121 of the anime Hunter X Hunter. It features the character Menthuthuyoupi, who undergoes a series of freaky transformations. Unfortunately YouTube is not allowing the clip to display when embedded, so here is a link to the video, which includes time stamps.

Ghostopolis (Age Progression)

In this graphic novel the protagonist goes into the afterlife and meets his grandpa, who is represented as a child. When grandpa "grows inside" his spirit form also "ages."

Quickie 6 (Age Progression & Muscle Growth)

This well-rendered animation by AgeGrowthFictions shows a skinny weakling turning into a big strong man. Definitely NSFW. This free video was originally uploaded to the artists's Subscribestar account, which I encourage you to visit along with his Deviantart account.

In related news, I've fixed the links for an earlier post that featured AgeGrowthFictions's videos "The Duet" & "Patrum Filius."

Artist smokinchips makes Muscle Growth art, and here are some of his pieces (FA account needed):

Construction Worker in Progress

Build a Bear

Huff, Puff, and Blow Me Away

For more muscle growth, here's a sequence by @theobromicart

Next up is a writer who worked on many stories involving age progression, called Aardvarkia on Tumblr. 

Flash Before Your Eyes

Speaking of  age progression, there is also BigBerserk, who draw and animates the subject. Here are some of his works (NSFW):

3 Variation AP Sequence

Thick Stache

Beard/Face Growth

"The Duet" & "Patrum Filius" (Age Progression and Muscle Growth)

Both of these digital animations by AgeGrowthFictions depict the transformation of a boy into a man. I cannot stress enough that both are NSFW on account of nudity and sexual content. Having said that, I will also say these videos are uniquely evocative (and perhaps provocative) in showing the process of sexual maturation. The age progression in The Duet starts at 4:41; in Patrum Filius it begins at 4:15.

Edit: the videos have moved from Vimeo to Dropbox. The links are:

"The Duet"

"Patrum Filius"

"Seek," "Hatena Illusion" & "Danino Yogurt" (Age Progression, Age Regression and Muscle Growth)

Here are three items involving age progression and the other age regression.

Starting with the latter, here is a commercial for Seek (an employment company) that involves a man aging down by 72 years:



The next two clips approach aging from different directions but they meet in the same place: muscle growth!

My thanks to APninja for recommending a scene from episode 11 of the anime Hatena Illusion,
where an old butler turns into a young and very well muscled jock:




Here is an Australian yogurt commercial from 1995. Lucky Aussies! I don't recall anything like this on American TV...

Boris e Rufus (Monster, Muscle Growth, and Age Progression Transformations)

Boris e Rufus is a Brazilian cartoon. In episode 20, "A Fonte da Juventude" (The Fountain of Youth), the protagonists journey to an underground land inhabited by Germanic piglets who have never grown up. The pigs concoct an aging potion that has unexpected effects...

There's also a very quick reversion scene.

In episode 3, "Cilada!" (Trapped!), the protagonists are visited by Nino the cat, who needs help to counteract the side effects of a scientific experiment...



There's another transformation at 06:43 -- reversions are at 6:03 and 08:30

"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:

TF Video Round-Up (Muscle Growth, Age Progression, Lizard, and Werewolf Transformations)

 Here are five videos of short transformation scenes.

* A music video for the song "Closer" by Lemaitre, featuring some age progression/muscle growth:




* A web animation from Marvel, Spider-Gwen | Marvel TL;DR, that has a quick Lizard shift:




 * A quick wolfman scene from episode 5 of the anime Strike the Blood:




 * A web animation called The Mind Electric, which has a werewolf transformation at the 0:40 mark:


The Mind Electric [non profit Animatic/Storyboard] (TallyHall) from MilaMilkchocolate on Vimeo.



* Finally, a mystery item. This is a trailer for a film made in Myanmar. As you can see, there's some kind of monster/werewolf transformation at the end. I'm having trouble tracking this film down (to be honest, I didn't even know Myanmar had a film industry), so if you know a way to get a copy, please let me know!

Gegege no Kitaro 2018 (Werewolf and Muscle Growth Transformations)

Daymon here with another transformation from Gegege no Kitaro, thanks to musclelover from our Discord channel. It's a well-animated werewolf metamorphosis from episode 27:




And here is Apuleius, bringing you another Kitaro transformation (thanks to AP Ninja at the Process forum), this time from episode 29. It's a weird muscle growth/age progression scene involving Victor Frankenstein, who in this show seems to be a cross between Frankenstein's monster and the Hulk...

Art Round-Up (Bear, Boar, Dragon, Hippopotamus, Monkey, Neanderthal, Orc, Tanuki, Werewolf, Shark, Muscle Growth, Age Progression, and Weight Gain,)

Note from Apuleius:
The majority of this post is Daymon's hard work, but before I hand it over to my hard-working colleague, here are some pieces I've found online...

* A raccoon dog sequence by @iDuSkFeRiRoC, inspired by a scene from the Kitaro anime.

* A kid-into-werewolf sequence by @YojoooHan.

* A fat cat sequence with plenty of weight gain by @CatLewder--and from the same artist, a NSFW deer TF.

* A "bulk" transformation from the webcomic League of Super Redundant Heroes. That burglar doesn't know a good thing when he sees it!

* I received the following note from a reader named Lamarcodon:
"hi guys, I just finished a comic that has one of my characters going through a few different 'getting bigger' changes-- taller, muscles, fat, just LARGER in general (I even tried to 'draw' his voice getting deeper as he grows). Here's a link to the first page, and the rest should have "next page" links to click on.

Tu mourras moins bête (Age Progression)

Daymon here with a suggestion from an anonymous commenter for an online french Edutainment series called Tu mourras moins bête, which has an age progression scene in the episode "Pourquoi les ados sont-ils si mous?". The video doesn't allow embedding, so watch it here.
