This clip from There Was a Cute Girl in the Hero's Party, So I Tried Confessing to Her (what's with all these ultra-long anime names?) is brought to you by the good samaritan at the The Male Muscle Growth Archives YouTube channel.
Episode 5 ("I Tried Being a Demon Again") shows the protagonist reverting to his demon form, though the main attraction of this scene is the muscle growth:
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.
In OVA 1 "a monstrous oni ogre disguised as the hero's female love interest reverts to his hideous true form," to quote Andréssaurio Rex, who found the clip.
In episode 25 has Nube's demon hand starts to act up; its seal breaks, causing his arm to completely transform:
Local yoko Tamamo examines the arm and says Nube's spiritual powers are at their weakest, and might allow the oni sealed in his hand to take over his entire body:
Thanks to ShareContent for recommending these videos on our Discord server. This anime features a transforming oni (demon), as you'll see in these clips from episodes 19 and 20.
Our thanks to Andréssaurio Rex for his hard work in finding and recommending all the issues and episode numbers used in this lengthy post. This manga/anime is "set on a fictional medieval island where humans are plagued by Yoma, humanoid shape-shifters that feed on humans." The Yoma are hunted, for the protection of humans, by "Claymores," human-Yoma hybrids.
In chapter one the protagonist Raki asks his brother about Yoma and Claymores:
Later on, Raki comes home to find that a Yoma has taken over his brother and killed their family:
And here's the anime version of the scene, from episode one:
Moving on to chpater 26 (vol. 5), a friendly villager turns out to be a Yoma in disguise:
And here's the animated version, from episode 9:
Chapter 42 (Vol. 8) has more Yomas shifting outdoors:
And here's the animated scene, from episode 15:
In the same chapter we see a Yoma torturing a Claymore until both of them turn into monsters:
Here's the anime version, also from episode 15:
In chapters 51 and 52 (Vols. 9 & 10) a "human" with a scarred face turns into a tall white Yoma to attack a town:
The hooded friend of the Yoma also transforms (after taking off his hood off-panel) and goes on the warpath:
Here are both scenes as they were animated for episode 18:
Lastly, in episode 21 the Claymores face a Yoma who can transform into a sexy lion-man (the manga didn't have an onscreen transformation, so I skipped it). The clip runs a little long, so that you can enjoy his lion form:
Update Time! It's been almost half a year since the last update, so thanks for your patience. The past several months have been one of the most barren periods for transformations since the start of this blog. But we've managed to scrape together 31 items for you, our largest update yet, largely thanks to the contributions of our readers (apologies if we've missed any). We hope there will be a shorter delay before our next update, but in the meantime we encourage you to join our Discord channel, where you can find other people to discuss transformations with and share images and videos on the subject. And now let's proceed with the first post, on Coyotl, Hero and Beast.
***
The hero of this Mexican miniseries gains the power to transform into the mythical Cóyotl, a nagual (spirtually and physically metamorphic figure) from Mesoamerican folklore, and uses his new power to go after the cartels. To be honest, his Coyotl form is something of a letdown (not enough coyote, too many tribal markings).
The two transformation scenes are in episode four, so I've edited them together:
If you care about spoilers you might wish to postpone watching the second clip, from the eighth and final episode. One of the villains transforms into a demon and fights our hero. We also get a little bit of muzzle growth from Coyotl:
High Moon was one of the first professionally produced webcomics. We covered it many years ago, but it's now been collected in the graphic novel Bullet Holes and Bite Marks (art by Steve Ellis), which is a good reason to showcase the opening chapters.
The comic opens in old west Texas, with bounty hunter Macgregor tracking down wanted man Eddie Conroy (seen in the wanted poster):
Two more pictures of the characters in human form, starting with Macgregor:
And Conroy, the werewolf:
Conroy turns out not to be the villain of the series, as we see when he encounters a pair of bat demons:
Conroy's hanging is interupted by Macgregor. As the pair fight the demons, it's revealed that Macgregor is also a werewolf (he becomes a demonic looking one):
Macgregor doesn't survive his ordeal, but Conroy does, and he assumes Macgregor's name. Later on he confronts another werewolf:
In the later chapters we get a brief glimpse of Conory wolfing out:
And a flashback to when he was first bitten:
Lastly, there's a scene of Conroy picking up a hammer and transforming into a demonic werewolf as he attacks a demon:
