Battle B-Daman

Sigma is a recurring character in Battle B-Daman. His B-Daman is Scope General.


Sigma first appears in a mask and a matching red uniform. Sigma has dark blonde hair with dark gray eyes and appears to be either Caucasian or Asian. Sigma is a skilled but cocky B-DaPlayer who claims to have never lost a B-DaBattle. Back at his home he is known as the Tiger of the South Sea.


  • The word Sigma is the 18th letter of the Greek alphabet.
  • In the anime Ababa is the one who knocks him out, while in the manga Castieo under Ababa's control is the one who knocks him out instead.
  • His B-DaBalls are medium blue - the generic B-DaBall color used by B-DaPlayers.

Battle B-Daman

Sigma is first seen masked defeating a B-DaPlayer Green Bug Man. He is next seen as a member of the Elite Eight, the top eight B-DaPlayers of the IBA Winners Tournament. He is scheduled to face Terry McScotty in his Elite Eight match but is confronted by Ababa who knocks him out and replaces him with Liena Grace Vincent. Sigma returns at Cain McDonnell's celebration and begins to rant at Liena who has stolen his identity. He is calmed down by Cain and decides to forgive Liena and leave the party. He is later seen in the crowd cheering Liena on. Sigma returns with Berkhart to help Yamato and Gray defeat News and Salz with his rebuilt Scope General.

B-Daman: Scope General

Scope General is Sigma's true B-Daman. But after Sigma was knocked unconscious by Ababa, Scope General is stolen by Liena. Scope General is dropped into the infested waters of the special stage set for Sigma (Liena) and Terry's battle by Liena to debut her own B-Daman "Garnet Wind".


Sigma makes his appearance in the manga where he is on his way to battle Terry McScotty.
