The Rasenrengan, is simply two Rasengan used simultaneously. Once created, both Rasengan's are used at the same time with greater force than a single, regular Rasengan. It is different than Twin Rasengan, because Twin Rasengan uses one Rasengan at a time to attack, while this technique uses both Rasengan at the same time. This, of course, requires quite a bit of chakra, likely double the amount used in a single Rasengan, which implies it might require Hermit Mode. As a result of using both this technique and the Wind Release: Rasenshuriken, Naruto used up all his senjutsu chakra, forcing him out of Hermit Mode.

Naruto used this technique against Pain's Animal Path when both were in Gamabunta's mouth.
