As we all know that Kurama's chakra is of the healing nature type. This is known from many mentions about it in the wiki page of Naruto Uzumaki.
My question is, what is the nature type of the chakra of the other Tailed beasts?
Note: This is my thinking why there should have been a nature type to each of the tailed beasts.
As we all know that when Rikudō Sennin was about to die, he split his powers among his two sons (the older son inherited his powerful chakra and spiritual energy, and the younger son inherited his powerful life force and physical energy). Similarly, when creating the nine tailed beasts from the Shinju, he must have split the chakra based on their nature so that each tailed beast had a unique natured chakra.
Any insight on this would be very much welcomed.
