Has anyone but me noticed the similarities between Juha Bach and Ginjo? Like how both of they both formed a sword from a medallion? Juha's star medallion came from his (drumroll please. ....) Fullbring! Yes! Juha Bach has a Fullbring! He somehow got Ginjo to turn on Soul Society and he became a Sternritter. At some point he must have left the Sternritter and started Execution. He already probably knew of Ichigo's potential and that's why he tried to take his powers. He knew that a Fullbring could protect a Bankai. The other War Potentials are probably Rukia, Toshiro and Ishida. Just my thoughts.
