Rex

Rex is a spider tank that was built in the war to help with the war but when Rex was in the hanger being repaired the hanger was attacked and he was left deactivated and alone for a long time until you came along and repaired him back in a working condition. You are a computer genius you found Rex while you are being hunted by someone or something because you stole some important information from a military base you are now on the from it and you know that it is close and you designed Rex to protect you (pick all of your characteristics) ( I was too lazy to make the character myself. Good luck,)
