Many writers have referenced Midnighter's trademark ability to predict the unfolding of a battle before it starts. Early in Ellis's run on The Authority, the character was described as having a mental combat computer, with neural-inductive implants, which he uses to run through a given combat situation millions of times in his mind, almost instantly covering nearly every possible result before the first punch is even thrown. This allows for the perfect response and counterattack, such that if Midnighter can possibly win a battle, he will. Ellis portrayed the Midnighter delivering a monologue on this ability to intimidate opponents; Keith Giffen later had the character distribute a business card to this effect, to save time. Issue No. 7 of the Midnighter solo series, written by Brian K. Vaughan, showed the character using this ability regressively, to visualise the desired outcome of a battle and work backwards logically to achieve it. The stand-alone Authority graphic novel Human on the Inside, by John Ridley, suggested the ability was reactive, and required an opponent to make a first move to define the possibilities for a response. Though this is contradicted by numerous earlier, and later comics. Midnighter was also unable to use this ability against the Joker due to the latter's extreme insanity.
