I hate to use this as an example, but it's the best recent one I can think of regarding making something out of nearly-nothing... look at Derpy Hooves. The MLP fanbase spawned an entire character out of nothing but an animation hiccup and the word "Muffins".
Just because a character is not given a full-exposition of their name, origin-story, childhood, lovelife, etc., on their first appearance doesn't mean they're "oneshot joke", just unexplored territory.
