It would seem that the Bijuu would have some sort of chakra element affinity based on their animal type; however, I have yet to see (or have forgotten about) any elemental attacks made by the bijuu.
Some things to note:
1) The Bijuu Dama is just positive and negative chakra, so that doesn't offer any insight.
2) The anime has taken some liberties with the manga, especially with Kurama (breathing fire when he breaks out of Pein's big rock), that suggest different elements. Also, filler anime has shown the Sanbi use water-based chakra blasts - but that is filler, so idk ...
Thoughts?
