Blue Thunder is Hwang's weapon in Soulcalibur, but in Soulcalibur II, it appeared as one of Yun-seong's weapons, despite Hwang's absence, and then in Soulcalibur III, the weapon was available for Hwang. However it does not have any special effects.

A sword that Korean Admiral Lee Sun Shin received in his younger days from his closest friend, Seong Han-myeong. When the Korean national hero, Hwang, went out on his second quest for the Sword of Salvation, the Admiral himself presented this sword to him. It does not do much damage with each hit, but its weight breaks the opponent's stance.
