Plusle

For a Pokemon that is all about positivity, there are ironically very few plus points about Plusle. Despite seemingly passable offensive stats, it is outclassed as an offensive Electric-type by the likes of Zebstrika, Rotom-F, Raichu, Electabuzz, and even Pikachu. Defensively, anything remotely strong will negate its presence completely, and it's even frailer than its cousin Minun. In addition, its Ruby Pokedex entry states that Plusle will cry loudly if its teammates lose. So much for positivity; a team of five good Pokemon plus one Plusle isn't likely to win very often against a team of six. To sum it up, Plusle is a poor addition to any team.
