It could also be due to a curse. For example, he might have offended a powerful witch or wizard who put a spell on him, causing him to transform into a monster. Another reason might be his own inner demons. If he had been suppressing a lot of anger, hatred or negative emotions for a long time, it could have manifested physically and turned him into a monster.
Perhaps he was in a place filled with dark magic or some sort of supernatural energy. This energy could have seeped into him and gradually changed him into a monster. It's also possible that he made a deal with the devil or some other evil entity. In exchange for power or some other desires, he was doomed to transform into a monster as part of the bargain.
Magic could be a reason. Just like in many fantasy stories, a magical spell or a magic item could cause the transformation. For example, a magic potion spilled on the centipede or a wizard casting a wrong spell near it.
Another possibility is a curse from the supernatural world. Maybe he entered a haunted place or broke an ancient taboo, and as a result, a curse was placed on him to transform into a dog as a form of penance or to teach him a lesson about respecting the unknown.
Magic or spells. In many fictional worlds, magic is a powerful force that can cause all kinds of transformations. If a magician casts the wrong spell or if there's some sort of magical accident, a man could turn into a dog.
Magic or supernatural powers could be another reason. Maybe there is a magical object that, when misused by a man, causes this transformation. It could also be part of a grand design by some higher - power entity in the story's universe to teach the man or society a valuable lesson about gender and pregnancy.
If he had a family, they would be terrified. His partner might leave him, not being able to handle the new, monstrous form. His children would be scared and confused. Even his colleagues at work would shun him. The transformation would isolate him from the normal social interactions he used to have.
In a slime monster transformation story, the transformation could be triggered by a variety of factors. For starters, a diet change might lead to transformation. If the slime monster starts consuming a new type of substance, it could affect its body composition and lead to a change in form. Additionally, environmental factors play a role. For instance, if it moves from a wet, swampy area to a dry, desert - like place, its slime might harden and transform it. Emotional factors can also be involved. If the slime monster experiences extreme emotions like anger or fear, it could cause internal changes that result in a transformation.
One reason could be overeating. Just like in the story of the forest monster that ate too many magic fruits. Another reason might be a change in its environment that led to more accessible food sources. For example, the water monster had more nutritious plankton available due to the fairies' spell.
The following are some recommendations for novels about men reborn as monsters: 1. [Disaster of the Raging Python: A legendary warrior reincarnates as a snake, complaining all the way until he becomes a dragon and rules the entire universe.] 2.

One possible reason could be Naruto's out - of - control power. If in the fanfiction Naruto has some new and extremely powerful abilities that he can't fully manage, Sakura might see him as a monster out of fear. For example, if he accidentally causes destruction while trying to save the village.
It could be a case of mistaken identity or a parallel universe situation. Or perhaps it's all part of a complex dream or hallucination.
