Not to be a sour goose, but problem is here that you aren't exactly selling it, duderino.
I'm sure you have more original ideas in your head, but the super people thing on it's own is just pretty much every comic book and manga out there. So it's best to name it after something which is entirely unique to your series, otherwise it will never stand out. I can't be more specific if you aren't sharing anything else, sorry.
No rush, through. Make a couple of pages first, and then try and think of something apt, that's what I generally do. If you have a naming theme for your characters, something to do with that can work, also. I find that 'word salad' or intentionally weird word combos can also be fun, but it's best left to series that are supposed to be extremely deranged.
