Rothion Alexander (ロティオン・アレクサンドル Rotion Arekusandoru) (born in 1564, died in 1604) is Sophitia Alexandra's husband, Cassandra Alexandra and Lucius' brother-in-law, and a blacksmith. Rothion and Sophitia's first encounter happened when Sophitia collapsed after a vision of Soul Edge. They were married after Sophitia returned from her second search for Soul Edge and they had two children, Pyrrha and Patroklos.
It was Rothion who forged the Omega Sword & Elk Shield used by Sophitia from holy ore given to him by Hephaestus. He also forged another sword and shield for Sophitia to use when Cassandra stole the originals. He also forged Cassandra's Digamma Sword, and reforged the Nemea Shield, which was damaged.
During and after the events of Soulcalibur IV
Rothion had begun to be looked upon with scorn, due to his inability to protect his wife and daughter. Fewer people begun to buy his weapons. Rothion became a tool maker because he felt the weapons he created as a blacksmith didn't protect anyone. He went to search for Sophitia, under the guise of trips with Patroklos, but he couldn't find a way into the Holy Roman Empire.
He told his son stories about Sophitia's journeys as a holy warrior, inspiring the young boy to become a holy warrior too. When Patroklos turned fifteen years old, Rothion died due to illness. Before his last breath, he told his son about Sophitia's death at the hands of the malfested, and that Pyrrha was kidnapped by a girl wielding a ring blade.
