Casshern Sins
Bolton was originally a Bandit looking for a way out of the Ruin, searching to join Dio's army as a way to find Luna and keep living. He and many other bots challenged Casshern as they all fell into the Valley of Ruin and were defeated, leaving Bolton the soul survivor, though he had been badly mutilated. He was greeted by a young humanoid girl named Niko who he was very irritated with due to her idiotic efforts to fix him.

When Lyuze explained that Luna died to Casshern, Bolton overheard and figured that the rumors about Luna weren't true. Lyuze assured him that Luna was dead but Bolton explained why he and his comrades fought to find Luna out of desperation for there lives. Devastated by the news of Luna's death, Bolton seemingly gave up on his life and awaited the ruin.

But too soon after the Valley where he was trapped in due to his injuries was attacked by Bandits. When he saw that Niko was introuble, it is revealed he was appreciative in her efforts to help him when he screams for her life when she was fatally stuck by a bandit. Swearing revenge Bolton was injured by the Bandit until he was able to grab hold of him with his single arm and crush him to death with the help of Casshern. after Niko passed on, Bolton was given Casshern's word that he would return with Luna in order to heal both Bolton and Niko. After they left, Bolton expressed great grief over Niko's death as he began to cry out in anguish.
