Galan of 616 + Terrax.

Versus:

The Xelee
The Culture
The Forerunners
The Xel'Naga

Not all at once. 1 at a time.

RULES:

Each civilization gets basic knowledge of his abilities.

Galactus is NOT allowed to just obliterate the whole galaxy. He must consume and destroy populated worlds in his typical fashion.


Can anyone drive him off? Run away? Avoid detection? Straight up kill him?

Edit: they are all at the height of their power
