Pokemon Nuzlockes became incredibly popular in the last few years, but there's an even harder challenge out there, one so difficult it took streamer PointCrow 15 months and almost 4,000 attempts to complete it.
The Kaizo Ironmon challenge is the most difficult test of Pokemon skill out there at the moment. You can read the full list of rules here, but the most important ones you should know about are as follows: Pokemon, movesets, and items are all randomized; you can only use one 'mon; enemy levels are increased by 50%; you can't use Pokemon with a base stat total (BST) of 600 or more, and you can't kill wild Pokemon, so no extra XP. The randomizers also switch all the stats of each Pokemon – its Attack stat may become its Speed, or its HP could turn into Defense.
