When the Bronze Saints arrive his subordinates take care of them, leaving Rhadamanthys free to descend to the underworld, where he eventually faces off against Gemini Kanon, but their fight is interrupted. He later kills Lyra Orphée when the latter tries to assassinate Hades. He later meets Kanon again and after a long battle, the Saint relinquishes his Cloth and performs a suicide attack on Rhadamanthys ending their lives.
