Winky was the hapless foil to the square jawed hero. He wasn't the standard "cadet" like the other shows had, but more of a green/young ranger (Rocky's ship, the orbit jet, almost always had an actual kid on it, and occasionally an old man, too.)
Winky was the audience surrogate most of the time. He was the slacker who had to ask questions so that the hero had an excuse to drop some exposition.
It's super weird to hear that he was involved in several dumb, violent crimes within a few days of the show's premier. But it's also 100% in character.
