He is a red ant who is voiced by John Byner (along with Aardvark who is also voiced by the same actor but impersonating Dean Martin like Aardvark who talks with a Jackie Mason-like voice). He is constantly chased by Aardvark who is obsessed with eating him and has made numerous attempts to catch him but they all fail repeatedly as Charlie is smart, cunning, and intelligent enough to foil Aardvark's plans and escape from him. He is also very strong as when he took vitamins which gave him great strength and beated up Aardvark.
