His name is echo. Well, that's not his actual name, but it's the name everyone calls him. Some call him this because that was his code name In his last, and first mission. That mission was to plant a bomb in a section of the hellhole to cave that part in. Others call him that because of the fact that he can still hear the screams of his friends as he escaped the hellhole, leaving them with the gas. He didn't have much of a luxurious childhood. He grew up In the ship building factory, where his dad died in a freak accident with a jet engine. After that, he had no adult to help him and sponsor him with his job. So he chose his only option. To become a guardian.
