In A Feud There Was (1938) Egghead made his entrance riding a motorscooter with the words 'Elmer Fudd, Peacemaker' displayed on the side, the first onscreen use of that name.

In 1938, Egghead continued to make appearances in the Warner cartoons, including The Isle of Pingo Pongo, and A-Lad-In Bagdad. However, animation historian Michael Barrier asserts 'The Egghead-Elmer story is actually a little messy, my sense being that most of the people involved, whether they were making the films or publicizing them, not only had trouble telling the characters apart but had no idea why they should bother trying.' Egghead made his second appearance in 1937's Little Red Walking Hood and then in 1938 teamed with Warner Bros.' newest cartoon star Daffy Duck in Daffy Duck & Egghead. Many cartoon historians believe that Egghead evolved into Elmer over a period of a couple of years. Egghead initially was depicted as having a bulbous nose, funny/eccentric clothing and an egg-shaped head (thus the moniker 'Egghead'). In 1937, Fred Avery introduced a new character in his cartoon short Egghead Rides Again. He is also a billionaire, who lives in a mansion and owns a yacht. Fudd cartoons include Chuck Jones' masterpiece ' What's Opera, Doc?', the Rossini parody ' Rabbit of Seville', and the 'Hunting Trilogy' of ' Rabbit Fire', ' Rabbit Seasoning', and ' Duck! Rabbit, Duck!. He speaks in an unusual way (rhotacism), replacing his R's and L's with W's, so 'Watch the road, Rabbit,' becomes 'Watch da woad, wabbit!' Elmer's signature catchphrase is, 'Be vewy vewy quiet, I'm hunting wabbits', as well as his trademark gloat, 'huh-uh-uh-uh-uh-uh-uh-uh.' The best known Elmer J. His aim is to hunt Bugs, but he usually ends up seriously injuring himself and/or other antagonizing characters. cartoon pantheon (second only to Bugs himself). He has one of the most disputed origins in the Warner Bros. However, unlike the tyrannical, power-hungry Marvin or the scheming, malevolent Sam, Elmer is dopey and unlikely to do Bugs great harm. He is one of the series' main recurring villains, along with Marvin the Martian and Yosemite Sam. Fudd is a fictional cartoon character, one of the most famous Looney Tunes characters, and one of the archenemies of Bugs Bunny.
