Pokemon that a nuzlocke changed your opinion of?

To clarify, this is about any pokemon that you feel differently about before and after using them in a nuzlocke, for better or worse. It could be a mon that most players overlook, but saved you in a tight spot, or a fan favorite that you felt didn't live up to the hype.

For me, my best example would be the lillipup line in BW. Prior to my ( admittedly unfinished) bw nuzlocke, I had completely dismissed the line as generic, only to be proven wrong, with it being the only surviving member of the original team. Dixie the Stoutland's speed, power, and surprisingly versatile moveset allowed my run to limp on.
