Java is the Neanderthal servant of Simon Stagg. He was first discovered by fortune hunter Rex Mason and revived by the scientific wizardry of Stagg Enterprises. Java was present when Mason discovered the Orb of Ra in the Egyptian pyramid of Ahk-Ton and was transformed into Metamorpho.[5]
For years, Java lusted after Simon's daughter Sapphire Stagg, but was unable to win her heart because she was in love with Metamorpho. This bred a bitter rivalry between the two; one that persisted for many years. Java even risked his life once to save Sapphire from a melting skyscraper, and was transformed into a petrified fossil for his actions. Stagg's scientific prowess saved his life and returned him to normal.[5]
During a time when Metamorpho was believed to be dead, Sapphire relented to Java's persistent advances and married him. Java became the father figure to Sapphire and Rex's mutant son, Joey. Java was not an inherently evil individual, but his moral base had been compromised due to his constant exposure to the unscrupulous Simon Stagg. He was also extremely selfish when it came to his wants and desires. When Rex abducted Joey from Stagg Mansion, Java flew into a rage and was determined to kill him. Frustrated by Java's defiance, Simon Stagg shot and killed him.[6] However, Java is later seen alive attending the funeral of Metamorpho, who was believed to be dead.[7]

Later that night, Java kidnaps Metamorpho and attempts to fuse him with Chemo. However, the process goes awry, forcing Java to call in Stagg's servant Freight Train to stop Chemo.[8] [9] Later, Stagg performs an unidentified experiment that enabled Java to transform into a Shaggy Man. However, he is defeated by Freight Train, who had since joined the Outsiders.[10]
