Speaking of precog. Dune has biological mutation that Leto II (the most powerful precog in that universe) purposefully engineered to be invisible to precognition (part and parcel of his plan to prevent anyone in the future emulating him and destroying the human race).
It should be 'easy' to acquire this because after a certain point in the books, basically everyone has this (or you can go for the original, which was Siona in God Emperor of Dune). It should be pretty effective (although it works better in herds of course, so there could be a comic book or novel that i haven't read/forgot that would be better). Any suggestion besides Zero (which i'd still vote for if he's not obviously insane/tortured since he seems to have only one power).
I'd generally prefer books over comics myself, because comics run forever in place and if it goes wrong she might be there for relative decades and not get the right power from dozens of power retcons that characters in comics go over time.
