There was a time when I thought Medusa was something of a goofy character. I mean, her super power was hair which could wiggle around and clutch onto things. It seemed a little lame, but I've amended that opinion over the years.
There's a fundamental weirdness to Medusa, a strangeness which sets her apart even among the Inhumans who are themselves given to oddity.
Medusa went from a small-time player to a longtime replacement member of the Fantastic Four during some of my peak reading years and my affection for her has only grown with time.
