Not quite, I'm asking what "you" think the zanpakuto spirit should be. And the "baboon with the snake tail" is his zanpakuto's spirit not bankai. So far (well as far as the anime went) we have seen the ice dragon: hyorinmaru, and the baboon with a snake tail: zabimaru, those are the true forms that reside in their respective shinigami's inner world. It's that spirit that a shinigami has to learn the name of to use shikai (and a "true" name to use bankai)
