Aeryn's is more tricky. Especially as she's super logic, super direct, built to adapt, and not given to any flights of fantasy at all (See: John Crichton). Problematic, especially, is that what she would do with that kind of power or ability changes all throughout her canon, because who she is/can be/what she believes(/knows) changes a lot.

But you know, at her base, the main urges still stays the same, too -- a) to be able to protect her friends from the lions and tigers and bears, as John puts it from all the things/people/places that do any number of truly horrifying things to them and b) to find a place where she can belong, now that there isn't one.
