Tommy Merlyn was the best friend of the famous Ranger of Irollan, Oliver Queen (aka, the Green Arrow). He was a spoiled rich kid from Star City, a city near the western border of the Stag Duchy.
Tommy died in a crossfire between his best friend and his father while trying to save the love of his life, an elf named Laurel. Unfortunately, he was unsuccessful and Laurel died with him. He stayed dead for 5 years until he was resurrected by his father's enemies, brainwashing him to hate his father for eternity. Though, he retained his hatred towards his father, he killed those who resurrected him, went to Heresh and slowly built an army. Now, he is one of the most notorious opponents of the Griffin Empire. He, however, only wants to destroy the Stag Duchy.
