Why do people so strongly believe that water and lightning have an extreme advantage over Gaara’s sand when the manga hasn’t shown such a thing?
-SAND IS NOT DOTON. Jeez, what is so hard to understand? Sand is not an element and even if it has some kind of elemental affinity, it would be wind...
not once has it been shown in the manga that Gaara's sand is weak against water. What you are all thinking of is oil.OIL. In the fight against Madara, he had no problem controlling it even after the sand was inside Mei's water dragon tech.
