Fukai or Blue Bee is the Jinchuriki of Eight Tails before Killer Bee .. He's the Jinchuriki of the Eight Tails when Orochimaru Tried to steal it and made it to rampage in the Land of the Hidden Clouds and that's the time where Orochimaru obtained the Half-part of Gyuki's Horn

Ah yes..."Blue Bee"

*sigh* I'm just gonna go back to the waiting room for the other Edo characters like Kimimaro or Chiyo. Or Kakuzu. (I would say Edo Itachi, but thankfully, he's here now.)
