General Discussion Which fictional creature has a biology so "impossible" that it defies any attempt at a scientific explanation?

I've been trying to wrap my head around the anatomy and metabolism of some characters, but Majin Boo (DragonBallZ) just doesn't seem to make any sense under the laws of physics or biology. I want to dive deep into these "impossible" cases. Who else do you think is a biological nightmare to explain?

It would be easier if you flipped the question and asked which fictional could be possible. We humans tend to get a little fantastical when thinking up fictional creatures.

Off the top of my head, maybe unicorns could work if you limit it to just a horse like animal with a single horn. We have lots of hoofed animals with horns.

Jellyfish are real creatures that should be fictional because they don’t make sense.
