Kabuto switched sides!!!!

Kabuto is a naruto character. I thought he was with Orichimaru. But why is he teaming up against him now? He is a mystery. But with the preview of the next epic episode, is he teaming up with Tsunade or on his own now?
I'd bet that kabuto could beat my least favorite character, Sausuke up in a second. In case you haven't noticed, this is a cartoon about combating ninjas. Naruto fans may say, Sauske is unbeatable, but such is not true. Was he not beaten instantly buy Rock Lee, and Gaara, and Haku, and Zabuza, and Orochimaru, and Itachi, and... oh, I could go on forever.
Ladies, and gentlemen, If you don't know who I am talking about, oh well. But here is Kabuto.
