Here is my back story for Specter:
Specter. His name was Zackary. When he was taken from his home on Jerusalem VII, he was taken while walking through the woods with his parents. One of the few Spartans that saw their parents faces before they were taken. It happened so fast, that by the time he got his "bearings" he was on a Pelican flying to a military planet called Reach. He was a great trainee, always obeyed and listened to orders. Although, when his fellow trainees were being mistreated, he stepped in to help them, even though he may have gotten hurt. He became buddies with Michael and Lachlan, two of the only friends that he had. Those three would always practice fighting together,they would all train together. He was a listener more than a talker, but when he talks, everyone hears it. He was called Horse Head (even though he had no hair) but later in life, he earned a new name, on that stuck with him till the end.There was one thing that changed his life forever. The reason he got his name, is because he took a team of Marines and 2 Spartans, and 4 ODST's with him on a special mission. While they were trekking through the woods of this mysterious planet that was just recently discovered, they were ambushed by that slimy species called "The Covenant. It was a vigorous battle, bodies flying everywhere, cries of pain from both man and alien. In the end, the humans won. With only Specter and a dying Spartan alive. As the dying Spartan, also called Emily by her fellow Spartans, was lying in Specters arms, slowly drifting away. The last few words that she ever spoke were to Specter, and they were this, "Try to live". From that day on, Specter lost all feelings. Whenever he killed something, feelings passed right through him like a ghost. He talks, but with a voice that even Death is afraid of. Stationed under the command of Reaper, Specter was happy to serve such a great officer. Especially being posted with his two best friends.
