Multi-eyed alien wolf demon thing. One day I will give them a name and story.

They have eight eyes in total, but usually only keep one or two open at a time. They're werewolf-like in shape but cat-like in behavior. Their insides are all a greenish blue color as seen here;

They're more animal-like than anything else. I guess I'd compare their intelligence to the dragons in How to Train Your Dragon. They can understand a lot of what you say to them and have a sense of humor but don't really "speak" or plot ideas or anything like that.
If anything they probably just laze around all day like a cat.
