What about trainer class sprites? Here's the Rocker:
As you can see, the Kanto rocker sprites are rather weird ones. First, the RBY Rocker has a whip (which is common in RBY trainer sprites), but at least you can still see he's a Rocker since the rest is fitting. But then, in FRLG? How in hell is that supposed to be a Rocker? No long hair, no guitar, no stereotypical Rocker clothes... Looks more like a hopper to me... =/
My personal favourite of all these Rocker sprites is the gen 4 one, it looks completely badass.
