Amortus is a one-off villain from the ThunderCats episode "The Touch Of Amortus".

Amortus is a strange being who was once banished to "the Land of No Return" by Mumm-Ra. The Touch of Amortus involves marking his victim on the cheek with his tentacle, thereby making it possible for him to communicate telepathically and place suggestions in the victim's mind. The Touch can also turn said victim to stone.

This is an oldie, not my best work but I like it :) The base of the bust is the entrance to "The Land Of No Return" as seen in the episode. Sculpted from scratch and painted with Revell model paints.
