Fan CastingX-Men Days of Future Past: Tales from The Underworld

20 years after Thanos and Doom's invasion of Earth, killing half of all life, and making Doom a God Emperor, The X-Men were forced into hiding. Now the X-Men have a chance at fixing things. They plan on taking the soul stone which they now have, give it to Cyclops, and send him and one person back to the past to give the stone to the heroes. The plan goes haywire, and Cyclops and Bishop end up having to fight a younger Magneto who is still evil and a younger Doctor Doom, when they're sent back further than they needed to go. Now they need to jumpstart a new time machine to get to the future and give the heroes the stone, but while they're doing that Magneto and Doom are still trying to get the stone from them. The movie ends with Bishop sacrifices his life to get Cyclops to the future where Cyclops give the stone to Thor, but when he gives it to them, he changes the future and disappears since that timeline will never happen. The post credits show Thanos with the Power Stone and Bruce Banner in a cage.
