>>49866838I have found (in multiple playthroughs), that his ability is not that bad, all things considered. His stats are impressive, he usually knocks out most pokemon in one hit, learns leech life, and has enough bulk to tank a few hits before his ability activates. Even then, whenever it does activate, it's usually for my benefit.
But yeah, I agree, he would be better if he at least has a hidden ability that could make him more competitively viable (even though I don't really play comepetitive, I just like building pokemon)
