Tentacles
What is the best way to show an alien monster? How to show something vile, alien, unpleasant? Very simple - give him tentacles or, as the word is often used, tentacles. Moreover, tentacles are by no means only for beauty - they attack from all sides at once, beat, crush and choke, and besides, they can rape. They also have suction cups, which are incredibly difficult to tear off. And if the owner of the tentacles also conjures, then everything becomes very complicated and unpleasant. Or it may not be a monster, but just some unusual creature. Some kind of alien. And he can be quite well-mannered and friendly, but at the same time a stranger. And the presence of tentacles only further emphasizes this.
