[@Heckno12] Yeah, Salandit and its Corrosion ability.

I'd say the worst typing is Bug... most of the time. There are exceptions. (Yanmega, for example. Ancient Power covers Flying and Fire weaknesses, and if it learns a Grass type move, that compensates for its x4 Rock weakness. Also, Speed Boost...) That and Bug is one of the types that has a nice variety of secondary typings - much needed ones, in this case.

Some day, I want to take on the challenge of creating a Bug type trainer character for something who's actually pretty good.
