I just read the The Mighty Thor Annual http://www.comicvine.com/the-mighty-thor-annual-thor-scriers-game/37-338511/staff-review/
Who or what is the Scrier? Is he a cosmic entity or just a really ancient being? Is he on a level with someone like the Stranger? He seemed to be able to fight Galactus, even though Big G was fighting another foe at the time as well.
