Tell me your favorite type of Monster-boy! (For Science) (Patreon)

I'm brewing another MHIRA Boi in my lab, but I'd also like to hear what each of you like...for science. Let me know in the comment and feel free to be as vague or specific as you like. Tell me about species, personality, or just fun little things you find appealing! 

Just let me know in the comments and I'll be holding onto this information for later....
