If sasuke didn't have fire release

[Soloist]

What other element apart from lightning would suit him

 

[BlacLord™]

You could say Wind because of his suitability to precision and blast-type attacks.

Or Water according to Ba Zi.

 

[V h o]

Water release for hebi Sasuke, he seemed the most cool headed of all his versions.

 

[Im Still Robin]

Water release for Hebi

For the rest Idk, lightning and fire pretty much suits him.

 

[Sugiyama]

Water release, so he would be able master storm release by combining it with lightening, it would suit him imo. U_U
