MCU: What Happened To Everyone Who Held The Mind Stone?

Once the Mind Stone and the rest of the Infinity Stones were brought back to the present, they were laid out in a special glove built by Tony Stark so they could be used. This was done due to their lack of an Infinity Gauntlet of their own, but it gets the job done.

After some discussion, it is agreed that there really is only one person who is strong enough to wield it, and that person is the Incredible Hulk! Granted, he's going by the name Professor Hulk at this point in the film, but his intellect doesn't undo his immense strength, and he is chosen to wield the glove.

When he puts it on, it clearly begins to cause serious harm, but that doesn't stop him from moving forward as planned. With some concentration and a snap of his fingers, the Hulk returned everyone who was killed in Thanos' culling to the present, albeit, five years after their initial demise.

Using the glove in this fashion nearly killed the Hulk, and it also permanently withered his arm in much the same way Thanos' was damaged. Thanos then emerged from the past thanks to some stolen Pym Particles, and he launched a new battle against the Avengers to recover the Stones. He does get a hold of them briefly, but not long enough to use the Mind Stone again.
