IF the Sentry is still aroung after the events of Seige...
Could he be used as like the Marvel Spectre, possessing the power of "God", bit only allowed to show up when his Boss decides to allow him to "Come out and play?"
Like if Galactus tries to devour earth, again, Beyonder shows up, Celestials return etc
Then his Boss will allow BOB to come back and clean up the mess?
Really, why not just post one thread with all of the above questions?
Anyway, the "golden guardian" might be a good argument for this kind of role, but it's not something I'm hoping for. Being the right hand of God leaves you with no idenitity of your own.
