There is this rumor a hero based on Sun Wukong, the Monkey King, would be added to dota. This rumor is old enough to be linked to the original dota so we are talking about ancient "news" here.

I think this would be the first totally original Dota 2 hero, and the bananas kinda makes sense given Icefrog did similar things when he released other heroes.

Still, given how long Pit Lord is taking to be released we may only see Sun Wukong bundled together with Half-Life 3.
