Read Annihilation. He manages to kill a being Galactus lost to.
Misleading!! He sacrifices himself to cause a cascade event that would end up in the destruction of two Galactus level beings.
Strange put them together to fight hugely powerful threats that no one else could handle. Which is exactly what I'm suggesting they get back together for.
I don't know why they disbanded. They were never really a team in the sense of the Avengers. Other members like Nighthawk and Valkyrie formed a more stable team, but Strange only called together the big guns like the Surfer, Hulk, and Namor when it was necessary.
See, I liked how the Defenders were like that. Each one of them were smug idiotic jerks that didn't want to deal with one another, but did by choice or by force, and ended up saving stuff. Sure, it gets old, but not in mini format!! Strange doesn't want to be on a team unless he's written by Bendis, then apparently he does this 180 degree character shift that makes him all touchy feely. "I feel bad about Civil War and not participating, and Bill Foster died. ...What do you mean I've inadvertantly caused deaths of dozens if not hundreds before, and didn't care then, because it served the universal good?"
I was a bit disappointed in that, myself. I didn't understand it at all. He spent all those years ostensibly atoning for the morally questionable stuff he'd done under Galactus, yet at the first sign of trouble he decides to hop back under Galactus' wing and agree to do all those morally questionable things again? Why? Galactus has never wanted for heralds, so it's obviously not because he thinks Galactus needs him or anything. Seemed like a reversion to the old status quo just for nostalgia's sake more than anything else.
He wasn't exactly atoning for what he did for Galactus, as much as doing what good he could for beings, as that was his nature. He constantly felt bad, but always justified it as they would've been dead if he didn't. Which is why he did it again, knowing of the Annihilation Wave, that Galactus, more than ever, needed help to survive, and the universe, in turn, would as well.
That, and Galactus told him he was like, the best herald ever.
"Lolz! Surfer, BFF!! :heart: "
Have his powers adjusted as a result of an altercation with Tenebrous and Aegis during such that his connection to the power cosmic (or ability to tap it) is greatly reduced or interferred with. The greater the exertion of his power, the more readily he is depleted and he has to seek out a more direct source of the power cosmic - this makes him almost Galactus like, whereby he depends on the power to live and must actively seek it out a lot of the time. Being on the Avengers then would make sense because he would have to restrain his abilites except in times of dire need, and would have a support network to help him come to terms with it and get him through tougher times. Plus there's the continuing sub plot of seeking to return him to his former glory because noble beings of his power level are sorely needed in the wake of the Wave etc.
Why would Galactus repower him with a problem?
Here's my suggestion, make him a Galactus herald, and attack Epoch for Galactus, reigniting Gravity.
And then just have him continue having the universe fear him, because they know the end is coming.
The end of Sakkar!! >: D They did think him the worldbreaker, originally. Would make sense he just leads Galactus there.
