They're all pretty bland to me, the most bland being "I'm awesome without powers" and "I am a part time detective", the latter doesn't even sound like a title, just a statement in a casual conversation...
15 seconds to Mars sounds the best but is also what everyone thinks that creep Jared Leto's band is called (it's actually "30 seconds to Mars"), so it feels like you just ripped that off, kind of like those Wattpad fanfics with titles that are 1D lyrics.
I think you should go back to the drawing board and come up with some new options. No worries, our first ideas are rarely the best ones nor are they the ones we end up going with, but right now none of those are it.
