Harvey Osborn is the Amalgam combination of Two-Face and the Green Goblin. He is an insane criminal and former member of the Terrible Three, alongside the Scarecrow and Siliconman.
He was sought out by the Night Spectre, for he was the last of the Souls of Power that he required. He first used the other members of the Terrible Three to try to capture him, but they failed. When Speed Demon interfered, the Goblin was able to temporarily escape. But Night Spectre was able to capture him and bring him to his Sanctum of Lost Souls.
The Night Spectre was able to take Harvey's soul and possess him. After the Night Spectre's defeat, it is uncertain what became of the Goblin, possibly being one of the many souls that were set free to the afterlife.
