Roger was discovered in 1997 in a medieval alchemist's lab beneath the ruins of Czege Castle, Romania by B.P.R.D. agents Liz Sherman, Bud Waller, and Sidney Leach in Hellboy: Wake the Devil. Waller explained that a homunculus is created from blood and herbs, stewed in a jar, and then incubated in horse manure. Although lifeless upon discovery, the as-yet nameless Roger was activated when Liz touched the socket on his chest, absorbing her pyrokinesis as she was subconsciously looking to rid herself of it. As Liz entered a coma, Roger sprang to life in a violent rage, killing Waller before fleeing the castle into the countryside. After Liz was rushed to the hospital under the supervision of B.P.R.D. doctors, Hellboy and Kate Corrigan arrived to find the homunculus in the hope that Liz's power could be restored to her. Meanwhile, the homunculus was wracked by guilt and prayed for God to kill him. However, he soon encountered his "elder brother", a more crude homunculus created before himself.
The brother sought to take revenge on humanity using a colossal homunculus that he created from human fat. The sinister homunculus captured Kate and planned to sacrifice her for use in the giant homunculus. Roger saved her, but his brother entered the body of the gigantic colossus and began to rampage. While Hellboy struggled against the colossal homunculus, Roger intervened by asking his brother to forgive him. His brother forgave him, and Roger was allowed to join the colossus. Roger then used Liz's power over fire to melt the giant body and slay his brother. Roger returned to base with Hellboy and Kate, and restored Liz's pyrokinesis. Roger, now without a source of energy, returned to his comatose state.
Three years later, B.P.R.D. scientists were stopped from dissecting Roger's comatose body by Abe Sapien, who used an overdose of electricity to awaken the dormant homunculus. The B.P.R.D. fitted Roger with a mobile generator and made him an agent. At the same time, they planted a bomb within him to prevent any uncontrolled outbursts. This decision would later be a factor in Hellboy leaving the Bureau. However, during the Hunte Castle affair in 2001, Roger proved himself as an agent at last when he managed to contain the Conqueror Worm (an energy-based monster from space) within himself, which nearly subsumed his psyche as he managed to destroy Herman von Klempt by throwing them both off a mountain. Roger was saved by the ghost of Lobster Johnson, who used a lightning rod to shock the Worm out of Roger.
Roger returned to work with the Bureau, fitted with a new generator. During the invasion of America by frog monsters, Roger proved to be very effective in wiping them out and eventually got promoted to a leadership role and led his own squadron of agents. However, his new-found cockiness proved to be his undoing. Surprised by the villainous Black Flame, who was leading the frog monsters, Roger and his team were blown to pieces.
Kate Corrigan went to France to secure the book that could restore Roger to full health. However, the ageless marquis who held the book attempted to bargain for Roger's corpse, using Kate as collateral. Kate managed to overpower the marquis by releasing the demon Marchosias, but in the ensuing carnage the book was lost and Roger's fate was sealed. As of the end of B.P.R.D.: The Universal Machine, Roger's body remained destroyed. When Johann Kraus communicated with Roger's spirit and asked him why he had not "gone on," Roger explained that because he is not human, there is no place for his spirit to go, so it simply remains within his body. Roger's spirit exists in a peaceful dream-world resembling an Etruscan shrine.
Roger told Johann that he was finally at peace and would prefer to stay "dead," but told Johann that he would like his body to be buried in the ground, "like a man." Roger's grave, marked with a false identity "Archie Stanton" (a reference to the 1966 film The Good, the Bad and the Ugly), was shown in the first issue of B.P.R.D.: Garden of Souls. It is engraved with a quotation from the King James Version of Job Chapter 32, Verse 9: "Great men are not always wise."
Roger appeared fleetingly in Guillermo del Toro's film version of Hellboy and its sequel, although only in his dormant state. When Trevor Bruttenholm first showed Agent Myers around the B.P.R.D., a large glass display case with Roger inside was visible in the background of a hall of artifacts, albeit only for one brief scene. In 2006, Roger made his debut as an action figure; he was part of the Hellboy Comic line (Series 2) from Mezco Toyz. Roger was one of four figures; the others included Rocket-pack Hellboy, Johann, and the Alien from Seed of Destruction and Conqueror Worm. Roger was also made into a Heroclix figure.
