Pokemon Go just added in over 80 new Pokemon with Gen 2. Not only are there brand new characters to be caught, some of your old favorites have a new evolution form that you can change them into. Onix is one of these, and the change couldn’t have come soon enough, as he’s one of the tougher Pokemon to find, yet his CP range is relatively weak. Now you can evolve him into Steelix though, but it takes some extra effort. Here’s our guide on how to evolve Onix into Steelix in Pokemon Go.
First off, you still need a bunch of Onix candy. To evolve Onix into Steelix you still need a full 50 Onix candies. You can get these, of course, by catching Onix in the wild, though eggs will give you the largest amount. This is random though, so focus on catching and hatching as many Onix as possible until you have the 50 Onix candy required to evolve.
Added onto this requirement is the need for a Metal Coat. This new Gen 2 item was added to Pokemon Go in the latest update. We have a guide on how to get these and all other upgrade items right here. The short answer is Pokestops. You can’t buy Metal Coats in the shop, and there’s pretty much no other way to get items in Pokemon Go, so you need to hit all the Pokestops that you can. Check out the guide for more tips, though it’s all focused on Pokestops for now.
Once you have 50 Onix candy and a Metal Coat you are good to go, simply hit the Evolve button and watch your Onix turn into Steelix before your very eyes. He’ll have his stats boosted and get a new moveset. These details haven’t all be worked out yet, but considering how useless Onix was before, it’s worth evolving him, even if the Steelix you get isn’t perfect.
