You can say that Doctor Stephen Strange saw it coming, but we sure didn’t.
After Thanos destroys half the population in the universe in Avengers: Infinity War, he used the Stones again, to destroy the Stones.
That leads into the whole time travel shenanigans of Avengers: Endgame, but the one thing we do know is that at the end of the movie, the original Stones are still destroyed. This means that Doctor Strange is without his most important weapon – The Eye of Agamotto.
This already deviates from the continuity of the Marvel Comics character, where the Eye is not the Time Stone, but the point is, when Steve Rogers returns the new Infinity Stones to their proper place in the timeline, he also returns the Time Stone.
Which means that all the magical abilities that Doctor Strange displays in Avengers: Endgame, he did so without the Eye of Agamatto. And he’ll have to do the same in the upcoming sequel, Doctor Strange 2, as the Stones are still destroyed.
One does wonder though – why didn’t Doctor Stranger use the new Time Stone to reverse the effects of the damage caused to Tony Stark when Tony used the new Infinity Iron Gauntlet? Surely the localised reversal of time on Tony Stark’s body is something Stephen could pull off?
Then again, Iron Man could also have used his new Nano armour to create an artificial Nano Arm to snap the Infinity Iron Gauntlet, instead of doing it himself and damaging his human body irreparably.
The point is, will we see a newly deposited Stephen Strange in the sequel, or what will be his new source of power in the MCU?
