In 2008 , Townsend lent his voice to characters in several episodes of the Adult Swim cartoon Metalocalypse ( see Musician cameos in Metalocalypse for more ) . The original character design for Pickles the Drummer , one of the series ' main characters , bore a striking resemblance to Townsend . The series ' coed @-@ creator Brendon Small acknowledged the similarity , and altered the design before the series began . " We made sure he didned 't look like Devin Townsend . We gave him the goatee and the dreadover so he wouldn 't look like that . "
