I honestly dislike it when stories feature characters like Harry transforming into a magical animal through animagus magic.
It makes magical creatures in the world feel less significant to me. Additionally, it grants magical humans an extra aspect that sets them apart, detracting from the uniqueness of other magical beings.
But one of the main reasons I dislike magical animagus is that it's always a Phoenix, Dragon, or some other extremely powerful creature which, in reality, is quite impractical. What are you going to do with a dragon, become a bigger target for a killing curse? Moreover, most of the time, it can only be used outside and even then, only where muggles cannot witness it. Authors often have to come up with reasons why it isn't used due to its overpowered nature.
Now, onto the point. There was one time I appreciated the concept of a magical animagus. I recently read "Harry Potter and the Artisan's Path," and I loved how it utilized Harry's animagus form. In this story, Harry's animagus form is a Demiguise, a small white monkey-like creature. When transformed, Harry can become invisible, and he has premonitions when danger is imminent. In his animagus form, he can essentially glimpse a bit into the future when danger is approaching. When in human form, he has a foreboding sense that something bad is about to happen, akin to a sixth sense.
This is great; it gives Harry a bit of power without going overboard. Harry already possesses an invisibility cloak in the canon, so the ability to turn invisible in his animagus form isn't excessive. Plus, most of the time, he isn't in his animagus form, so his danger sense isn't too overpowered. It actually feels useful without being an all-powerful advantage.
I recall seeing another story where the protagonist could transform into a Niffler, which was cool without being utterly ridiculous.
What do you think about magical animagus forms? Do you use them? Do you agree with me, or do you think I am wrong?
I am curious to see what others think of magical animagi, thanks for your answers in advance.
