Roger the Homunculus is a fictional character featured in the Hellboy and B.P.R.D. comic books published by Dark Horse Comics. He is an unusually large homunculus, a humanoid being said to be created by means of alchemy. Initially revived by Liz Sherman, Roger is one of the early supporting characters of the "Mignola-verse", appearing alongside other "enhanced" B.P.R.D. agents including Sherman, Abe Sapien and Johann Kraus under Dr. Kate Corrigan. Fictional character biography Roger was discovered in 1996 in a medieval alchemist's lab beneath the ruins of Czege Castle, Romania by BPRD agents Liz Sherman, Bud Waller, and Sidney Leach during the Wake the Devil affair. 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 enters a coma, Roger springs to life in a violent rage, killing Waller before fleeing the castle into the countryside. After Liz is rushed to the hospital under the supervision of BPRD doctors, Hellboy and Kate Corrigan arrive to find the homunculus in the hope that Liz's power could be restored to her. Meanwhile, the homunculus was racked by guilt and prayed for God to kill him. However, he soon encountered his '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 is 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, BPRD scientists were stopped from dissecting Roger's comatose body by Abe Sapien, who used an overdose of electricity to awaken the dormant homunculus. The BPRD fitted Roger with a mobile generator and made him an agent. At the
