I remember a cartoon about a space "cowboy"(maybe) he wore a large brimmed hat and a black cloak.. he also had a big scar down one side of his face. And wore laser pistols. Anybody remember the name of the cartoon??

How about Captain Harlock?

"The character is introduced in Adventures of a Honeybee (1953), but did not make its debut as lead character until 1978's Space Pirate Captain Harlock. Since then, the character has appeared in numerous animated TV series and films..."
