Slowpoke

With a unique typing and outstanding defensive stats, Slowpoke easily distinguishes itself as one of the tier's most solid walls. Its ability, Regenerator, gives it a unique niche that allows it to switch in and wall a multitude of threats without sustaining too much damage in the long run. This, coupled with Slowpoke's high HP and Defense, useful resistance to Fighting-type moves, and access to support moves such as Thunder Wave, Slack Off, and Scald, makes Slowpoke a very difficult wall to muscle past. Unfortunately, Slowpoke does have quite a list of weaknesses and a pitiful Special Attack stat, making it relatively easy to defend against. Still, its bulk and longevity make it one of the tier's best walls.
