A jungler that can take control of a jungle minion.
So basically I thought it would be really cool if there was a Jungler that Riot can create, that would be able to take control of a minion, in other words the champion could enter a minion and look like the minion and take full control of it for a few seconds, I personally think it would be hella awesome and cool, + there would be a load of plays that could happen because of that, and I have never seen that in league of legends, I have only seen it in Dota 2 and Heroes of Newerth, I really think it would be amazing and I have wanted Riot to create a champion like that for ages.
