Freddy the Fly is the titular character from the Freddy the Fly segments on the notorious DIC Entertainment show; The Wacky World of Tex Avery. He is voiced by Billy West.
Why He Sucks
He is very sadistic towards Amanda Banshee. In fact, he is (or was) the reason she became mean-spirited.
Unlike many other protagonists from famous cartoon rivalries such as Bugs Bunny, Daffy Duck, Woody Woodpecker, Tweety, Road Runner, Screwy Squirrel, and Charlie Ant from the Ant and the Aardvark where it was usually justified for them to fight off and humiliate their antagonists due to their antagonists starting the conflict in the first place, Freddy the Fly starts his and Amanda's rivalry rather than vice versa.
Most of his gags are basically gross-out jokes.
He is incredibly annoying.
Just like most of the other characters from The Wacky World of Tex Avery, his design is ugly.
His character is basically a stereotypical hobo-type character.
He often causes a lot of destruction around Amanda's mansion whenever Amanda tries to kill him.
He is a Karma Houdini as well and never gets punished for his actions.
