Natu

Natu was a forgotten Pokemon in DPP. It was one of the many NFE Pokemon that never saw any use, and its evolution, Xatu, didn't do any better. But in BW it got two huge gifts: Eviolite and Magic Bounce. Although it is still outclassed by Xatu, it doesn't have to worry about it because the big bird is in UU, giving Natu a chance to shine in RU. With an incredible ability, good bulk, and reliable healing in Roost, it helps the team in many ways. However, Natu does have its drawbacks. Horrendous offensive stats mean that Natu will often become set-up bait. Natu also has a Pursuit weakness, and while Reflect somewhat mitigates this, it still gives the little bird trouble. Finally, while Natu can be quite bulky on either side, it cannot be both due to its low HP stat, and must choose to invest in either physical or special bulk.
