Pachirisu

Though Pachirisu lacks the Flying-type coverage granted to its fellow squirrel Emolga and a niche, game-changing item such as Pikachu's Light Ball, I promise there is still a reason to use it. That reasoning, however, is buried rather far under the ground, in a place to which Pachirisu can't venture (you know, due to typing and all that). As such, the mystery of Pachirisu's presence in NU is as of yet unsolved. However, those brave souls who have dedicated themselves with a passion to understanding Pachirisu have made leaps and bounds in between the generations, discovering a latent ability--Volt Absorb--deep within the recesses of Pachirisu's dreams. This ability has truly catapulted Pachirisu sky-high, where, if only for a moment, it can soar just as well as Emolga.

It also makes Pachirisu a really nice counter to Plusle or Minun for when you're having a Battle of the Cutest with your friends.
