Don't use it unless it is dual type with a good type

In gen 1 it's OP, it is super effective against psychic type which was the absolutely God like type in gen 1, and dumb, basic bug types are super effective against it, so in gen 1 it was over powered, gen 2 and onward not really

It only had 4 moves and the best one was only on Beedrill, a Pokemon with the second lowest attack stats behind Butterfree. They are good in let's go though

They are better overall, but stacked up there in the lower tier
