Secret Invasion

What if invaders in Secret Invasion were White Martians
same Marvel Earth as time of invasion
do heros win

Not a chance.

Since the skrulls were genetically enhanced with marvel heroes' powers and they still lost I believe that the Martians wouldn't have done better. It might be harder but with the God Squad Asgard and the Eternals there earth would be still safe

they die like the skrull

Heroes win again.

Heros, but it would have a tougher battle

Assuming the same general battle tactics...
I'd at heroes could eek out a victory but it wouldve still been incredibly close.

When the skrylls invaded not all skrylls had powers... Like the ones that went after wakanda...

However the supermanesque of the Martians would overwhelm most of earths heroes.... Unlike the sktulls where some were godlike and others weren't.

Yes close but the heroes eek out a few. Martians for the markority
