Sigma (Digimon)

Sigma is a mysterious and masked character from the Digimon V-Tamer series.

He is a member of the Alias III and is the first member to fight Taichi Yagami and Zeromaru for Neo Saiba. His Digimon is Pie the Piedmon and their feelings are connected to each other. When Zeromaru was fighting Piedmon, part of his mask breaks off the same time as part of Sigma's mask. Taichi give Sigma the opportunity to quit the battle for Piedmon to be spared which Sigma is grateful for. When Neo found out, he ordered Arcadimon to fight Piedmon. Sigma is right behind a glass window with Neo unable to do anything. At the point of Piedmon's death, both Sigma and Piedmon screamed. Arcadimon absorbs Piedmon's data and Digivolves to Rookie as Sigma is imprisoned in the dungeon. He later escaped with Rei Saiba and Mari Goutokuji and sides with Taichi to stop Arcadimon. He keeps his friendship with them.
