He did it once in the beginning of Shippuuden when he was trying to get the bells from Kakashi the second time. But its my understanding that alot of that fight wasn't in the manga so it probably wasn't real.Originally Posted by Abdula
It would have made sense if he could do the Rasengan one handed now, but needed to use a clone to do Oodama Rasengan, but that doesn't seem to be the case, as he's had to clone it in several times recently.
