Onix

Onix is one of the lucky Pokemon who, like Lickitung, received an evolution in a later generation and was originally designed to have stats on par with Pokemon in their last stage of evolution. With a massive Defense stat, great Speed, and a wide movepool, Onix can fulfill numerous roles on a team. It can act as a reliable Stealth Rock user with Sturdy, which allows Onix to survive a hit that would normally OHKO it at full health. A drawback to this rocky snake is that it sports mediocre HP and Special Defense stats, making it susceptible to special moves such as Surf. All in all, Onix can find a spot in nearly any team that is looking for anything from a good sweeper to a useful wall.
