Bang-Boo is a character in the Battle Arena Toshinden series. He made his first and only appearance in Toshinden 4, as an initially playable character.
Bang-Boo is a cyborg and one of the Gerard Foundation's finest creations, with nothing other than a brain and fighting instinct. Wielding two huge cannons, he is an almost flawless warrior. Conscienceless and emotionless, he was designed to be a machine of war, but was instead used as a pilot in the army.
One day, he was given orders by a mysterious individual to obey the Chinese sorcerer Genma and enter the fourth Toshindaibukai as a part of his team. He was also commanded that if Genma had managed to gather all of the Four Sacred Arms, he would then have to eliminate him and his threat. Having no will of his own, he began to follow these direct orders without question.
