 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.
