No need to get worried, really. Right now it is just a proposal.
As H4H said, if there are other characters, whose niche are - for example - the whole techy stuff, then I can easily narrow it down some (i.e. dropping the whole Inventor / Engineering stuff would be no problem, if someone else wants to play a character with that shtick, but if noone does, I see no harm in her being able to be useful in that field).
That really depends a lot on what other characters are there...
BTW, Fusion isn't particularily good at combat. She only has straightforward damage attacks (there are a lot more options than just that) and only few combat-related Advantages. I would consider her combat-abilities pretty average for the PL.
As for the skills... those are quite average, too. Only Technology and Vehicles are very good. +10 is useful, but not that much, when the maximum at the PL is +20.
Benefit: Wealth is mostly just fluff... it is the most useless Advantage, ever (because there is nothing useful in the game, that you can buy with money... everything costs PP
