Super Rabbit, an animal superhero in lighthearted children's adventures, debuted in "Comedy Comics" #14 (March 1943). Hart also worked on "Pookey the Poetical Pup" and "Ding-a-Ling the Little Bellboy" in "Krazy Komics"; "Wacky Willie" and "Andy Wolf & Bertie Mouse" in "Terrytoons Comics"; "Skip O'Hare" in "Comedy Comics"; and the heroic-adventure feature "Victory Boys" for Timely. Other Golden Age comics work includes "Egbert and the Count" and "Marmaduke Mouse" for Quality Comics' "Hit Comics", of which one critic wrote, "Ernie Hart's 'Marmaduke Mouse' and 'Egbert' were, especially in the beginning, solidly drawn and reasonably funny, but lacked a convincing sense of action and character."
