As in, it's really good, but people never see it because it's outshined.
Aquaman is as strong and fast as Superman because of living his life underwater, but is outshined because, well, Superman is as strong, and can do more shit. So all Aquaman has is one or two gimmicks which aren't as good.
I'm positive there are Pokemon that fit this description.
Quilfish?
