What do you think is a under appreciated mythological creature

Ziz, while the Behemoth rules the land and Leviathan rules the ocean, everyone forgets about the Ziz which rules the sky. One of the three great hebrew beasts.

Griffon, okay so everyone knows about the Gryphon but I feel like people overlook it a lot. if Lions are the kings of beasts and Eagles are the kings of birds, that makes the Griffin the king of all. Plus they're known as protectors, royalty, etc and as far as I can tell they don't really have an origin. I mean sure they originated in persia or someshit but they've popped up all throughout Europe and there's no real birth stories or anything of them, they're simply just there.

Hundun, legendary faceless being and symbolizes primordial chaos in chinese mythology. It looks like a winged butt with legs dunno if this really counts as a mythological creature, cause it existed before the universe's creation and is kind of just there. But I once saw a picture of it and laughed my ass off, so now everyone must know about it.

Questing Beast, okay so technically this is just a giraffe, but shush. The questing beast from Arthurian legends is a horse with leopard spots and a snake head/neck.
