Everything about it is garbage.
All of its evolutions are, too.
Mothim's just another Bug/Flying, and a terrible one at that.
Scizor is a waaay better Bug/Steel, Parasect is a better Bug/Grass, but considering Nincada is the only other Bug/Ground, Sandy Cloak Wormadam is ok at best.
Not to mention, did anyone notice Burmy's a Pineco ripoff?
