Biography:
Bismarck Waldstein is the man you bears the title of the Knight of One under Charles, the strongest
amongst the Knights of the Round. But before he bears the title of Knight of One he was the Knight
of Five. Despite his status and combat abilities, he believes war should be used as a last resort,
and also sees strength without restraint as needless violence. His left eye is shut be stitches and
he pilots the Knightmare Frame Galahad.
During the second battle of Tokyo he leads the Britannian forces guarding the shore against Li Xinkge
invasion force. As Li and Bismarck battle, Bismarck complements Li on his skill when he purposefully
takes a hit to move into position to rescue the Chinese command vessel.
During Schneizel's attempt to Kill Emperor Charles, he intervenes to stop Suzaku's assassination attempt.
The live command on Suzaku, causes him to flee before they even begin fighting, meaning that Bismarck was
very dangerous. When Lelouch kills the emperor and becomes Emperor, Bismarck leads the three remaining Knights
of the Rounds and a squadron of Knightmares in an attempt to remove Lelouch from power. But Suzaku kills all
but Bismarck who reveals that he has geass in his left eye, which allows him to see a few seconds in the
future. The only person he had ever needed to use it on was Marianne, and now Suzaku. Suzaku used his
live command to stall Bismarck's geass. Suzaku then sliced Galahad in half gasping Marianne's name.
