In the manga only two attack happened with the kyuubi before pain ran to get closer to nagato to do chibaku tensai. First was the kyuubi sprinted/dived at him, pain tryied to push back but the kyuubi redireceted the energy back at pain sending him flying. Then the kyuubi started gather bubble chakra for the attack that was also used on ochimaru, and pain dropped a block on him, diverting the attack away. Then pain ran, generally speaking pain was completely overwhelmed and knew it and retreated.
In the anime he had his head being grabbed by the kyuubi directly and created shields and water, just so they could have running on water.... AGAIN, even when it's been done in many many scenes in the show, and didn't need to be added to another scene that it didn't happen in. The episode was lame against all my expectations.
But whatever like I said before I personally put more emphasis on the manga then the anime.
Link to the chapter if you would like to reread.

edit: I guess my point int he manga he didn't fight the kyuubi just avoided his attacks as best he could before doing Chibaku Tansai, and I think that says something about pain's strategy and how he goes about doing things, thus says something about his character.
In the anime he was just AnimeBadAssBadGuyNumber6 who charges into direct head on combat until beaten into the ground like a nail, instead of a cool a calculating battle pragmatist, who retreats from the get go to set up a trap/attack.
And yes anime pain did retreat, but only after RoadRunner Legs, Rollypolly face, and Nailman, I guess he ran out of loonytunes jokes so had to return to canon.
