[Terrible-D]

I hadn't even heard of his passing. His groundbreaking work on Howard and Man-Thing was a little before my time, and my only experience was from a few ratty issues at the public library. Admitably, some of the humor and social commentary went well over my pre-teen head.
A lot of people were unknowingly exposed to his work. He was a story editor on the 80's Transformers and G.I. Joe cartoons. He also was the creator of Thundarr the Barbarian.
