What exactly does the Power Cosmic do for you?

Typically what powers does Galan give to his herald's?

@bluejay4: MANY. From virtual immortality to energy blasts, to flight to healing powers to MORE. Galactus spares no expense when it comes to those he deems worthy to be his heralds! This might be his way of keeping them in line because if he can reward them so well then they'd better do what he wants and find more planets for him to munch on to show their gratitude! This doesn't always work of course, even Galactus sometimes makes the mistake of trusting the wrong person, But let's just say messing with someone who has the technology to give you the power cosmic is NOT a good idea...
