Originally posted by zopzop Rachel was holding back though, by her own admission and so, in a way, was Necrom. He didn't want to kill her because he wanted the PF from her. So he was slowly escalating his attacks in order for her to keep tapping into the PF. He couldn't access the PF without her.
Give the Silver Surfer enough time and he can destroy the contents of the universe too.
Well, might be stretching a bit but my point is, that's something they "may have" accomplished with time,
but Rachel also literally stated:
that neither herself or Necrom had the power out-put to take out the Solar System,
which is why Necrom had to use his surroundings to do it.
(a couple moons, a planet or two, and finally the gas giant to finish the job)
So whatever her "not holding back" potential is ... it's below Solar System buster.
They weren't destroying solar systems good friend, not even one outright.
Necrom took chunks out first then ignited a gas giant to finalize the destruction,
that's as far as they were going according to Rachel's own words.
Imo, Rachel would've helped destroy solar systems faster if she had joined Necrom's maneuvers,
but I also think that statement is hyperbolic, cause the circumstances
would've had to been them fighting without interruption for a very long time, (many solar systems in a galaxy)
before taking out the universe imo.
