SPARTAN-1337 is the main character in Odd One Out. He falls out a Pelican ship onto a planet where three children and two teenagers find him. During this incident, his general mood was, "Not again." He is very self-centered and incredibly egotistical to the point of almost being megalomaniacal about it. He seems to be very powerful in hand-to-hand combat possibly the strongest, but seems to be average at weapon use. Against the assault of the "ultimate weapon," he had to use several shield grenades. He also seems to be kind to people only to get their attention and admiration.
