Shellock is a very old monster who lives in the Underground and resides in New Home. He's the Royal Detective, and is a boss monster who has lived for thousands of years. He's jaded, intimidating, and relentless in his vindictive hatred for humans and desire for revenge. Very deep down, though, he has a soft side, but it's closed off. He's old, yet incredibly skilled with his trusty revolver. He's wise and traditional. His kids are dead, and his wife doesn't speak to him anymore. He's a Veteran.
