Vileplume

Vileplume is a fantastic defensive pivot thanks to its great typing coupled with solid defenses, and its easy access to recovery options in both Giga Drain and Moonlight enhances its durability and capacity to handle many offensive Pokemon. Effect Spore is a great ability, punishing contact move users such as Kangaskhan, Primeape, Hitmonchan, Tauros, and Hariyama, further aiding Vileplume's matchup against physical attackers. Unlike most other defensively inclined Pokemon, Vileplume has a great Special Attack stat that allows it to hit hard even without investment. Unfortunately, its typing gives it weaknesses to many common special attacking types, such as Ice, Fire, and Psychic. These common weaknesses in conjunction with its low Speed leave Vileplume easily forced out early-game and can make its role as a defensive pivot a bit more difficult.
