He-Man and the Masters of The Univers: The New Adventures - Butthead Action Figure (MOTU, 1990)

Remember this guy? Well, neither do I and for good reason - he only appeared in the second, very unpopular iteration of He-Man, known as "The New Adventures". 

Also, what's with that name? Butthead? Really?? 

Condition: Good, but his extended neck tends to get stuck. It sort of works, we just can't figure out if it's just badly designed, or there's a mechanism inside that has made the head more stubborn over the years.
