all options are interesting, 1 she would have to limit herself to, 2 i'm sure if he advances far enough she can deal with the martian, and how much super man could use something like portal to get rid of him after all he can't cross dimensions, 3 not very detailed to really form an opinion, 4 would be very interesting but again I doubt they would leave it alone if they find out (it would be nice if there were different types for each thing),5 needs more detail as this path has many possibilities (like the most common way to gain powers is the skills of whoever she parasites ),6 this one I can't imagine how it would fit, 7 if it's just body strength it would basically be the same as leveling up in an rpg,8 it has potential but at the same time seems to me the biggest chance of screwing everything up (mainly by the workings of the dc world)
Well the best one's I think are 1, 2, 4, 5, and 6 from what I have heard and thought, 1 and 2 are easy to know why, 4 you could end up making it so they can improve herself as well and did you get inspiration from 'Her Majesty's Swarm' for this? and if not read it because it could help like having a hive mind to be able to see and control them from large distances, 5 from what you said is upper good but would take time and like 4 can use it to improve herself by maybe stealing other's DNA like supper boy and the martian while being able to learn what other's know and monitor them without them knowing like potentially the batfamily, and 6 I do not know but sounds op, while 3 is a nono because you mess with one of the most powerful existences in existence, and finally 7 would only work well (aka at full potential) in the apocalypse reality that I recently heard about
