Raichu

Raichu, of course, is a lot cooler looking than Pikachu, especially with its more whip-ike tail, but Pikachu's status as the face of the franchise has shoved its own bigger, stronger, final evolution into its shadow. That has to suck for Raichu, knowing you're objectively better in every measurable way but that some young punk is going to soak up all the attention instead. Poor Raichu. Raichu was even portrayed as kind of a jerkoff in the anime. Pikachu didn't even want to ever be a Raichu.
