Bangoo (バングー Bangū) is Rock's adopted son. He lost his parents in tribal warfare and was the only native to develop a relationship with the "White Giant" during his first years in the New World. Eventually Rock took Bangoo as his son and raised him. Being kidnapped by Fygul Cestemus to serve as bait to bring Rock and take his soul, he was rescued by Rock and settled in Europe. After four years, he decided to go on a journey to prove his manhood, so he embarked back to his native land.
Bangoo is a free spirt that is close to nature. He is respectful and down to earth and vary strong willed. He is a friend to all living creatures and will stop at nothing to secure the balance between man and mother earth. Bangoo would also protect himself and loved ones at all costs and is willing to stand and fight for what is right.
- In Rock's Soulcalibur ending, Bangoo appears as an adult carrying Rock's axe. This has led some fans to speculate that he may appear as a playable character in future Soul games, though this has yet to occur. Bangoo can appear in Soulcalibur IV as a created character.
- He is playable via cheat devices in Soul Blade, implying that he was originally meant to appear as a secret character. However, his name is misspelled as "Bangu", and he is called Seung Mina in battle.
- Daishi Odashima stated a few times that he would like to include this character to the roster of Soulcalibur V, though this didn't pan out in the release.
- He is voiced by Fujiko Takimoto in Japanese and Kimberly Forsythe in English for his appearance in Rock's Soul Edge ending.
