- “I'm one heck of a Mama myself!”— SPARTAN-1337 as he's about to face Pluton
SPARTAN-1337 is a SPARTAN-II Commando of the UNSC Naval Special Warfare Command. He is the main character of Odd One Out, the non-canon and satirical interpretation of the Halo universe produced by Toei Animation for Halo Legends.
- Main article: Odd One Out
SPARTAN-1337 is depicted as being extremely accident-prone and clumsy. All throughout Odd One Out, Spartan 1337 is quite cocky and confident in his abilities despite his comical blundering. None of the inhabitants of planet Cronky are aware of his status as a SPARTAN-II: he introduces himself with great gusto, which does nothing to clarify his self-proclaimed status as one of the "strongest warriors in space."
- His SPARTAN tag, 1337, is a reference to the internet meme known as "Leet Speak," which uses numbers and symbols as letters. 1337 is a hint towards his elite status as a SPARTAN as "1337" translates to "leet" as in "elite."
- He is referred to as "Big Robot Man" by the inhabitants of the planet due to his bulky armor, which is a reference to the fact that some players new to Halo often see SPARTANs as robots instead of augmented humans.
