Fight takes place in a neutral reality limited to one universe, existing outside of the multiverse that encompasses 616.
Jaspers for the easy win.
Nullification is useless against Jaspers.
And that's the only option Galactus would have (shoot Jaspers with the UN)
If Galactus nullifies the Universe Galactus is in, Galactus nullfies himself,
while Jaspers survives. (MJJ ftw by default)
On the other hand, since this a merged Jaspers/Fury,
even if it was plausible for Galactus to survive the nullification of said Universe,
(which he cannot, according to the History of the UN then and Now)
Jaspers would still have Fury's abilities,

And Fury is more durable than Galactus, (including complete immunity to nullification)
so Jaspers can withstand anything Galactus hits him with other than the UN,
plus Warp him into anything he wishes. (since Galactus is Reality)
The reason Jaspers couldn't Warp Fury in Un-Space,
is because Fury was basically immune to Reality manipulation.
Why Jaspers couldn't use his own body though as Reality is a mystery (maybe PIS)
Or perhaps there wasn't enough substance to work with in his single body,
or perhaps he can only use outside material (other than his body I mean)
to Warp Reality.
I'm not too sure, but I'm reviewing my comics as we speak.
