Here is the second evolution I said I was doing, the evolution of KABUTOPS
-Evolves from KABUTOPS when equiped with Kings Rock
-"This carnivouros pokemon hunted on both land and sea, attacking small crustaceous with his long hook-like pinsers and tail, which where able to pierce trough any kind of shell. Anything they grabbed was as good as dead."
This evolution is based in another Ordovicic predator, the Mixopterus, a huge sea scorpion [link]
As far as I knew, KABUTOPS was already based on a sea scorpion, so I just made it look more like a real one, changing and adding some details.
Hope you like it
