12) Neo-Otyugh
Otyughs have always been part of D&D monster pantheon, but Neo-Otyughs disappeared for a while before returned to 5th Edition. What baffles me is wondering why Gary Gygax decided regular Otyughs needed to evolve, Pokémon-style, instead of just changing its stats. At any rate, this guy looks like someone stuck the suit of a Japanese kaiju villain in an industrial microwave. Also, sometimes it feels like half of the creatures in the Monster’s Manual have tentacles.
