Kakuzu and Hidan were the Maniacs.
Itachi and Kisame were the Romantics.
Sasori and Deidara the Artists.
Konan and Nagato the "god complex" friendzone.
Obito and Zetsu were the trolls.
deidera and tobi they actually worked together then the other akatsuki members not to mention they where my faves always threatening to blow up tobi lmfao
i think itachi and kisame were the strongest and actually enjoyed each others presence, they kinda seemed like friends.
but my fav is deidara and sasori that was just bad ass
