Wolfbane Studio (Werewolf Transformation)

Thanks to Noodles for finding this video and posting it to our Discord server. Apparently it's "a werewolf model and transformation system" created for an independent video game developer. 

Saros (Alien/Monster Transformation)

Thanks to Mr.TF on our Discord channel for recommending these cut-scene endings to the video game Saros. The "bad ending" is a gnarly monster/alien/demon metamorphosis:

 

 

 

The "good" ending is a partial curtailed TF (but how is that good?!)

 

Inayah—Life After Gods (Monster Transformation)

Our thanks to Eran on Discord for alerting us to this cutscene:

 

Amazing Spider-Man & more (Lizard Transformations)

Let's start this lizard-themed post with a look at his video game appearances (found by Andréssaurio Rex). I'd say the best bits are in the first minute; the rest can be skimmed/skipped.

 

Up next, some pages from Amazing Spider-Man #630:

And here's a relevant page from the book Marvel Anatomy: A Scientific Study of the Superhuman:

"Marvel's Avengers" Video Games & Spider-Man: Brand New Day (Hulk & Muscle Growth Transformations)

Here's a compilation of  "All Hulk Transformations in Marvel's Avengers" (the video games):

 

We were going to post a video of the Hulk-out from Spider-Man: Brand New Day, but it's was taken down. Let's see if this one stays up:

If it gets taken down by the time you read this post, try this vertical one, or this one on Reddit, though it has the noisiest audience in the world.  

 

For a bonus, here's a quick Hulk-out from the Marvel Rivals: Domination video game:

 Thanks to Andréssaurio Rex for all the videos!

Ultraforce, Regular Show, and Arkham City (Monster Transformations)

Thanks again to Andréssaurio Rex for finding these clips.

Several monster/muscle growth transformations are in episode five of the 1995 cartoon Ultraforce, involving a villain named "Sludge," whose "normal" appearance is that of a blue anthropoid. The first one, actually a reversion, starts at 6:52, to which this video is cued. Then there's a transformation at 7:07, another reversion at 10:04, and a last TF at 10:50.

If you're in the mood for more sludgy monsters, here's a slime-blob TF from episode eight of Regular Show: Lost Tapes:

And continuing with sludge monsters, here's a scene from the video game Batman: Arkham City, where the Joker reveals himself to be Clayface in disguise:

Transformation Round-Up (Monster, Imp, Vampire and Muscle Growth Transformations)

 Thanks to Andréssaurio Rex for locating the first four clips in this round-up.

A monstrous "rager" TF from the video game Gears of War: Judgment:

A chimpanzee turns into an alien-chimp in episode 17 of StuGo:

Some vampire facial transformations from the Swedish horror film Frostbite (2006). The first is cued to 27:37, the rest occur at 01:01:38 and at 01:17:09 and concludes after an interuption at 01:17:45. 

From Rahan episode one, a bear-to-imp/gnome transformation:

Some comedic muscle growth found by Kevrai, from the Atomic Betty spin-off webseries Crash-Test Noah, episode six: 

And for a comedic bonus, some absurd muscle growth from this Japanese commercial, also found by Kevrai:

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!

"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:

"Bell Hell's Intro" & "McFarlane's Evil Prophecy" (Jackal and Werewolf Transformations)

Thanks to Andréssaurio Rex for these videos. First, a werewolf in the animated intro to Bells Hells, a "campaign" of the web series Critical Role: 

 

And another intro, this time to the 2004 video game McFarlane's Evil Prophecy. Since there's a direct cut from the head of the transformed character to that of Anubis, I've classed this as a jackal transformation. On the other hand, it's induced by the full moon, so who knows?  

 

Dispatch (Bat Monster Transformation)

In episode three, Robert decides to cut Sonar from Z-Team, leading the deeply angered Sonar to shift into his Mega Bat form: 

Nightholme (Werewolf Transformation)

Thanks to Leone Vukan from our Discord server for recommending this video game trailer:

Zoe: Interactive Story (Werewolf Transformations)

Zoe: Interactive Story was designed to be played on smartphones and consisted mostly of still images, with a few instances of very limited animation. It was marketed in several countries and seems to have been popular in Brazil, judging from the videos on YouTube. 

The story includes a handsome werewolf, who's seen transforming at the end of episode 10:

Episode 20 has a brief partial TF at the end:

And the end of episode 19 of season 2 has a reversion scene:

Black Myth: Wukong (Pig and Monster Transformations)

Our thanks to Beastwolf for finding this video game cutscene. Zhu Bajie is cursed to transform into a pig (the video should be cued to 3:03). Then at 4:25 he turns into a monster pig, and at 4:53 he reverts:

Evolutale (Tiger Transformation)

This independently made Japanese video game can be played here, but if you just want to see the transformation scenes someone has posted a run-through. 

The premise involves the character waking up in a mad scientist's lab and getting zapped by rays that make him undergo a four-stage transformation into a tiger. I've cued the video to start at 11:24, and if you watch until 12:52 you'll see all the stages.

Dave the Diver (Age Regression)

Thanks to Mr.TF from Discord for recommending this video game scene. A character named Otto is taken back to childhood by a dish he remembered from his early years:

Unreal Engine 5 (Werewolf Transformation)

Thanks to Noodles on our Discord Channel for recommending this clip from a game engine: 

Hi-Fi Rush (Werewolf Transformation)

Thanks to Fenrison on our Discord server for finding this video game scene. Chai faces Roquefort, a cyborg wolf in sheep's clothing:

Callisto Protocol (Alien Monster Transformation)

Over the course of this video game Leon Ferris, an antagonistic prison guard exposed to a Biophage Pathogen, transforms gradually, and then suddenly, into an alien monster:

Destroy All Humans 2 (Alien Monster Transformation Scenes)

The first transformation is caused by the release of Blisk spores that turn people into alien-human hybrids. The second has Crypto cornering Ivan, who retaliates by infecting himself with spores to avoid questioning:
