OK so here's something I've been wanting for a long time: play as Ganondorf. Hyrule Warriors lets me do that, and I loved it, but so far there has never been a male Gerudo who wasn't shown as being evil. Every few thousand years or so, one of these men become the King of Darkness, fight Link, yada yada. HOWEVER, it is stated that only a HUNDRED years passes between the birth of male Gerudo. Not every male Gerudo is Ganondorf, or the Gerudo would never live as comfortably as they do in BotW. They are cursed with birthing an evil king, but many only know because of stories passed down by generations. All that to say, they aren't an evil race in BotW.
I have a theory that is probably totally wrong but I want to be right. 100 years before BotW, Ganondorf became Malice and shed his Gerudo body. His body remains under Hyrule Castle, we see in the trailer, preserved much like Link was, only not in youth. It is therefore entirely possible for another male Gerudo to have been born in those hundred years, without the Triforce of Power or the evil of Ganon. Possibly a sibling to Riju, the young Gerudo chieftain we meet in BotW, but as future King of the Gerudo this prince would be training impossibly hard to learn the techniques of magic and combat. I could see him being isolated in the desert with only his mentor and barely knowing the rest of the world. If a person like this was playable in BotW 2, trying to rid the world of the curse brought by the Gerudo, I would be immensely happy. Zelda looks like she could be playable, and this prince would be almost as hype as her. Story missions would have you swap between them, and outside there would be areas you could change out. They would have different types of weapons, and could each open different areas or do different quests, all in the same map. I think that this would make BotW 2 one of the best games of all time, especially if they work out a fun way to play differently between characters.
