S1·E15 Millenary Knights of God

Joseph and Amanda are caught and taken to the headquarters of Zwölf, a mysterious institution that meddles in forbidden science. Among its members called Apocalypse Knights are people whom Amanda knows well, and this deeply disturbs her. The Apocalypse Knights manipulate specially developed ultra-weapons and easily take down the horde of Amalgams that had previously given XAT such a hard time. Amanda is more enraged rather than stunned.
