Carnivine

Carnivine is an odd Grass-type, sporting some good base attacking stats, some weaker defensive stats, a horrible Speed, and Levitate, which is what really separates Carnivine from its Grass-type brethren. While almost completely outclassed by other Grass-types, Carnivine does have a niche in its Swords Dance set which, while almost always inferior to Leafeon or Venusaur, can work with Levitate. Levitate makes Carnivine completely immune to Spikes, Toxic Spikes, and Earthquake, allowing it some unique opportunities to set up a Swords Dance, such as on a Choice Rhyperior's Earthquake (something Venusaur could only ever dream of doing). In short, Carnivine has a niche, but is usually harshly outclassed.
