The Terrible Tempered Mr. Bang in TOONERVILLE PICNIC (1936)
I think Mr. Bang was the best character the Van Beuren studio ever used, even if he wasn't in the best cartoons the studio made (and the studio didn't create him). There is an effective absence of background music in the set-up scene. This film is the last completed by the studio.
Dogface in A SELF MADE MONGREL (1945)
If there is a single, solitary Famous Studios character I can relate to, it's DOGFACE!! Check out the cynical "cartoon blues" hidden by the heavy dialogue.
Wally Walrus in CHEW CHEW BABY (1945)
I can't praise the "concept" of Wally enough; a pompous, lovelorn, gluttonous "solid citizen" who could probably dig in and enjoy his life if it wasn't for the woodpecker. Gullible and dumb, but not as grievously cretinous as Fudd. And an extreme case of the voice "being" the character. Other actors were never as effective. Woody certainly had a colorful gallery of adversaries.
Butch in GRIN AND SHARE IT (1957)
Deadly greed deeply camouflaged in a stereotyped Irish jollity. Even his music is harmless bumptiousness as he sets up his nefarious traps.
