Odd One Out is a parody story of Halo universe and is not canon. It follows the adventures of Spartan 1337, a member of Master Chief's unit who suffers both from a severe ego and horrendous bad luck, although still a fairly competent fighter in his own right.
This sweeping science-fiction saga delves into the rich “Halo” universe with seven exciting stories (told in eight parts) focused on Master Chief’s mysterious origins, the Spartans’ advanced combat capabilities, and the tense rivalry between Spartans and Orbital Drop Shock Troopers (ODSTs).
