The Impending Collection consists of eight Comic Book Covers found in Impending Lockboxes. Completing the collection results in the recruitment of Doctor Doom. The daily task for Impending Lockboxes starting from December 7, 2013 to January 8, 2014. Though the lockboxes are obtainable, this is the first case of the lockboxes not being able to be opened, as they can not be opened prior to December 25th, 2013.
No, my greatest foe is the phenomena you know of as "Incursions". Collisions between worlds which threaten not just Earth, but the entirety of reality.
I created the Syndicate to distract S.H.I.E.L.D. and give them an effigy to burn, while I seized control and steered this world towards salvation. But somehow, you dared to resist me.
Since that time I have pitted my genius against the Incursion events alone. While you have done naught but hide here and mount a pitful defense, Doom has gone through to the other worlds!
I have beheld the structure of the multiverse, and found it ROTTING. Can you even conceive of the catastrophe that bears down upon us? Would I deign to speak to you if it meant less than the annihilation of all?!
I can no longer afford to waste time on S.H.I.E.L.D.'s petty resistance. You will join me, and we will bring about an end to this disaster. Continue your impudence, and I will crush you.
Whatever you choose, know this. There is nothing in all of creation that can stand against my will. Not Incursions, not S.H.I.E.L.D., not you! Doom is SUPREME OVER ALL!
