04: Oh-Four is what you would imagine a cross between Slenderman, a raptor, Slade, and a Wendigo. Thing is fast, strong, and very hungry. With it's long arms it can strike at a distance, faster than a snake. Most things won't hurt it. But special magic weapons and attacks will. Of course, it would be hard to find someone with a magic knife, sword, gun, or magic energy. So try not to fight him

01: Built after 04, Oh-One is a smaller version of it that can be mass produced. It uses special types of guns and blades to defeat enemies. Can be killed by regular weapons, but it takes a lot more strikes to pull it off. They are commonly called "Nithlis" (plural - Nithly)

02: A winged varient of 01, Oh-Two flies around and uses it's claws and sharp teeth to kill it's enemies. Same issues as the last one, but flies. Commonly called "Cacklebats"

03: This thing is not like it's siblings, for it is a squid. Swimming through the ocean at fast speeds, it's only weakness is magic weapons or very powerful normal weapons. Must be, very, very powerful. Commonly called "Octosharks
