- ONI Operative (Custom): Someone dark, broody, lots of secrets, equal footing with Rook rankwise, but a bit of a rabble rouser. This character will introduce The Rookie to deep cover ONI work. As I may mention elsewhere in this casting call, the book Halo New Blood sees Alpha-Nine undergo one final mission as a full team, to the planet Draco III. Their task was to disperse the rebel insurgence there led by CPT Ingridson. During it, The Rookie was ordered by Buck to secure their exit, and in doing so got himself captured by the rebels. SPOILERS AHEAD: As a result, in a brash final action Ingridson takes the Rookie with her. To a great number of fans, and after reading it; myself included, this was an unsavoury action by the writers particularly due to the methods used to do it. Ultimately, this film will aim to serve as not only a second wind for a game that stood out to a lot of fans as the best in the franchise but also bring back a beloved character which to most actually served as a blank slate and a pair of boots to fill, a ”john doe” if you will (which is literally his name btw) that could be any one of us. To cut this tangent short, this ONI operative plans to undo this event without unwriting that book, by using CPT Ingridson to fake The Rookie’s passing, in order to use him for a deep cover and highly confidential ONI mission. One that will link all of the unanswered questions of Halo 3 ODST.
