Gligar

With a useful base 85 Speed and superb base 105 Defense to compliment its unique Ground / Flying typing, Gligar should not be frowned upon in the UU tier, despite its NFE status. Gligar's typing grants it both an Electric and Ground immunity, as well as neat resistances to Bug, Fighting, and Poison. Perhaps the most impressive niche about Gligar is its versatility; it can set up Swords Dance and/or Agility and Baton Pass the boosts to a teammate, use Toxic to stall its opponent, break stall with Taunt, or be a deadly set-up sweeper with Swords Dance. It's not all good though, Gligar's special stats are pitiful and its Attack stat is only average. However, as long as its teammates are able to cover up its unfortunate weaknesses to common Water- and Ice-type attacks, Gligar will make a formidable addition to your team.
