A Creator/MarvelComics writer best known for his brilliant work on [[MerchandiseDriven licensed property]] comics like ''ComicBook/RomSpaceknight'' and ''The ComicBook/{{Micronauts}},'' creating memorable characters and settings that long outlasted the [[{{Toys}} products]] that inspired them. He is the creator of [[ComicBook/GuardiansOfTheGalaxy Rocket Raccoon]] and the co-creator of Comicbook/CloakAndDagger and Comicbook/CaptainUniverse. He also worked on mainstream characters like the ''Comicbook/IncredibleHulk'' (including the memorable [[AlternateUniverse "Crossroads"]] saga), ''ComicBook/IronMan'', ''ComicBook/SpiderMan'', and ''ComicBook/AlphaFlight.'' He was the tragic victim of a hit and run driver in 1992 and suffered brain damage from the accident. He has been in institutional care since then.
