I'll describe him in a fast way, he's crazy,insane,evil but has a small good side. He looks insane/evil because of Nightmare. He was the first to be injected with nightmare venom. Nightmare told him nobody loved him nor his parents.The venom gave Echo a fake childhood about him in his mind. Hours later he came back to his house and his parents were worry about him. Echo didnt care and kil*ed them. And became insane...! U can request in my request pic! #Stark
