Mr. Slug

As you may be able to tell by his name (and yes, 'Mr. Slug' is what is officially recorded in all appropriate legal documents). Mr. Slug is a humanoid slug-mutant thingie. To be specific, he's a Hivist Lord - one of the bug-people whose mutations are so widespread and inhuman compared to the Ordinaries that he's instantly promoted to rule over a large group of them from birth. Funnily enough, Mr. Slug rules the slimier, stickier Hivists.

Despite his horrific appearance, like most Hivists Mr. Slug is reknowned for his surprisingly calm and well-spoken manner. Looking like that, he's had females and occasionally males fall in love with him from species who should know better.
