Byuwen (위험병기용 사이보그 뷰윈, wiheombyeong-giyong saibogeu byuwin, Dangerous Cyborg Byuwen) is an artificial robot that was brought by Ha Jinsung to intercept and block the path of Kallavan and his 3rd Division when they were headed to the Last Station. It carried the El Robina's Anti High Ranker Shinsu cannon.[1]
When Jinsung was stabbed by Khun Maschenny Zahard by lightning spear attack, he lost energy to stand and almost collapsed. He then ordered Byuwen to destroy the Kallavan Warship.[2]
