Type: Null is a pure Normal type, and has an alright design, but interesting concept behind said design. Now, Type: Null is actually pretty solid, with it having good stats all around, a good movepool, just kind of meh with the abilities. Only downside is that you can't really use Type: Null in playthroughs much since you don't get it until way late in the game when your team is already set in stone usually, so overall, I just never had a chance to really get a strong appeal towards Type: Null, even though it isn't quite half that bad, and that's what made me end up ranking it here.
