3. Sunkern
Notorious for being the weakest pokemon in the series stat-wise, Sunkern is a cute grass pokemon that resembles a seed with a leaf on its head. No arms, no legs, no real limbs, just a bulb with a happy face. Now, it would be interesting if Sunkern were introduced later on in the series, but no dice – it's been in the series ever since generation 2, and there haven't been any weaker pokemon introduced since. While weak, Sunkern isn't by any means useless. It doesn't have the afflicting capabilities of other grass pokemon, but it can learn fairly powerful moves which receive STAB bonuses rather early on, like Solar Beam or Giga Drain. Sure they're not the best moves around, but hey, beats Tackle.
