After work Robert Hellsgaard returned to his village to find everyone including his family has been murdered by monsters. Since then he has devoted his life to exterminating any monster he finds.
Robert Hellsgaard is a brilliant engineer who was around in 1898. He came home to his village one day to find everyone including his family murdered by a pack of werewolves. While in prison he escaped with the aid of Ulysses Bloodstone and helped him to kill monsters. While helping Bloodstone he built a suit of armor, and a portal to Limbo to serve as a dumping ground for the dead monsters. But they were attacked by Dracula and Hellsgraard was trapped in limbo. Until a team of scientists from Japan went to his old workshop, to find information to help defend Japan from monster attacks. They then opened the portal a Hellsgaard stepped out. Hellsgaard then helped the team and they became the "Hunter of Monster Special Force" who are devoted to the extermination of all monsters.
Robert Hellsgaard wears a cybernetic armor that he permanently resides in. It appears to have kept him alive from 1898 to the present. The suit uses flamethrowers fueled by holy gasoline, gatling guns loaded with silver bullets filled with acid and sunlight-infused projectile buzz saws made from the iron of a wicked pharoah's priest.
