Camerupt

Camerupt arduously competes with fellow Fire-types in almost every role, but it is greatly let down by its terrible Speed, defensive stats, and 4x weakness to Water. However, unlike most other Fire-types, Camerupt can alleviate its Speed issues with Rock Polish, which together with its powerful STABs makes it a very intimidating offensive threat. That same Speed stat also allows it to thrive in an environment that no other UU Fire-type can survive in: Trick Room. With effective methods to overcome his Speed, an immunity Electric-type attacks, and a vast offensive movepool, which includes Explosion, unique dual STABs, and great attacking stats on both ends, Camerupt can make for a solid Pokemon on any team that is willing to support it, despite its shortcomings.
