So in this thread I would like to talk about pokemon in various gens that had a small niche at what they do. However that niche is not enough to give it much use in OU or even UU if you want to include that in this thread as well. Heres an example. Camerupt Overall it isnt very good in the ou metagame. It has a huge water weakness that pokemon like suicune can abuse. Its incredibly slow and its not very bulky. However due to its ground typing, it is the only fire pokemon that isnt negatively affected by ttar's sand. It can probably make a decent scizor counter. Its also able to take rock and grass type moves neutrally and is immune to electric types. Even with those perks, its still never seen because its still generally a waste of a pokemon spot. As much as I would like it to be, fire types bar heatran and infernape had a harder time in ou because of their common weaknesses.
