Eternity, Death...
If I can't choose them, I'll pick Thanos, Odin, Reed Richards, Doctor Doom, and Mary-Jane.
Odin would be my (useless) bodygard, Thanos would supervise a project he would made with Doom and Richard that will help saving my ass, and Mary-Jane is in the case that the three boys come with nothing.
Hmm, I would select Mystique who I would ask to disguise as myself. Then I would let Galactus kill him ... If he somehow found out it was me, I would throw Skrull at him ... which is also disguised as me.
If this did not work, then I would run to Access who would teleport me to DC universe, and hide there like a *****.
Uncle Sam to teleport me to The Heartland
Ask for Tiamut's help
Doorman to teleport me to Oblivion's realm temporarily
Summon the Phoenix Force.. if Galactus still wins, at least I get to see one of the most epic fights between two legendary pokem... I mean abstracts before I die
Or I can just ask for Spectre's help
