I had this idea but I'm not sure how it would work nor did I have enough knowledge about any series to make it work
So my idea is like a person (reincarnated/transmigrated/or just naturally born in that world) has a power like a werewolf transformation power
and they have like four forms of transformation. and in the first form or the base form they got a tail and wolf ears. Also I was thinking of making them a more slim build. something like Bet from Danmachi. and the gender don't matter. like you can make them female male it don't really matter. and they have enhanced senses and enhanced physical abilities. and maybe an extremely sensitive tail and ears(if you want an H scene)
and then the second form would be like a slightly more human version of the full power form of Mazuka from Noblesse. you know the fur on parts of the body. and they would gain more animal instincts. and then with this transformation they grow in height and their fangs grow longer and they get some small claws on their fingers. and their feet grow and gain some claws too. and all their physical abilities get a big boost. like their speed, their strength and their flexibility. Especially their regeneration gets a really big boost.
In the third form they would gain alot more wolf like characteristics. like full body fur and a slight snout. and they would become way more muscled. and get big fangs and claws. and slightly more animalistic feet. and all their animal instincts would be boosted alot. and their physical attributes would be boosted again. especially their regeneration. and this one would have wolf shaped eyes.
Then the fourth form would essentially be just a giant wolf. and in this form they would have incredibly advanced senses. and incredible physical attributes. along with near instant regeneration.
and a few "powers" they would have is an imprinting ability. like when they see someone they can consciously (or unconsciously) fall permanently in love with them.
and I was thinking of giving them some dog like attributes. like waging their tail. and the loyalty that some dogs have. and tail and ear movements.
and maybe you can put a handicap on their powers so that their not too OP. like with every transformation they experience excruciating pain during the transformation process. and they're just like completely out of energy when the transform back to their normal form.
and I was thinking if you want more cute and funny stuff you can make it so that they can control what size of wolf they want to transform into. like a puppy size.
and if you need some numbers on their height to get an idea on it. then let's say your person is like 6 foot 3 inches (or 75 inches or 1.905 meters) in their normal form. then in their second form they would be like 6 foot 9 inches (or 78 inches or 1.9812 meters). then in third form they would be like 7 foot 3 inches (or 84 inches or 2.1336 meters) in height. then in their fourth form they would be like 6 foot 3 inches on all fours.
and if you need more numbers a wolf's pulling power is like 200 pounds (or 90.718 kg) and a wolf's bite power is like 500 pounds (or 226.796 kg) and a wolf's running speed is like 37 mph (or 59.54 km).
and while I had this fully detailed wolf powers idea. I had no idea how to implement it into anything. so there you go... a detailed werewolf power idea free to use at your own convenience.
see ya later
