SPOILER WARNING FOR THE ENTIRE X-MEN FILM FRANCHISE
While the X-Men film franchise is a lot of fun to watch, there are a vast number of plot holes in X-Men movies. Even after X-Men: Days of Future Past tried to salvage the franchise and merge both the original and First Class timelines, it somehow created even more X-Men movie plot holes, tangling the timeline to an even greater extent.
While most X-Men film plot holes don't detract from the enjoyment of the movies themselves, some of the holes are too big to ignore. Here's a list of the worst plot holes in X-Men movies.
Mystique's DNA would be useless for Sentinels.Trask's plan in X-Men: Days of Future Past is to use the mutants' own powers against them by having Mystique's DNA give the Sentinels the ability to mimic a mutant's power. However, it is long established that Mystique can only shapeshift physical forms, not copy a mutant's attributes.
Sure, the Sentinels could possibly shapeshift if Trask was successful, but they can't outright mimic other mutant abilities. Want proof? When Mystique copies and fights Wolverine in the first X-Men, the real Logan was able to chop off Mystique's claws. To make his Sentinels truly have mutant powers, Trask would need to muck about with Rogue's DNA, since she can absorb the actual abilities of any and all mutants.Is this plot hole unforgivable?
When did Mystique stop impersonating Stryker?
At the end of X-Men: Days of Future Past, Wolverine is captured by a person who appears to be William Stryker in order to undergo the Weapon X program. One brief glimpse of yellow in Stryker's eyes reveals that it is Mystique posing as Stryker.However, in X-Men: Apocalypse, Mystique is an underground mutant freedom fighter and Stryker, the real one, is back in charge of the Weapon X program, which includes Wolverine. When did this happen? Was Mystique discovered? What was Mystique's plan in the first place?Is this plot hole unforgivable?
The mystery of multiple Emma Frosts
In X-Men Origins: Wolverine, sets in the '70s or '80s, there's a young girl named Emma who can turn her skin into diamonds. In X-Men: First Class, one of the main villains is Emma Frost, a telepath who can also turn her skin into diamonds in the 1960s. This can't be possible given the timing and place.While Bryan Singer and other producers can deny the plot hole and say that the two characters are different people altogether, it's incredibly coincidental that they both have the same ability and are named "Emma." The X-Men franchise has hundreds and hundreds of characters to choose from, so why even invite comparison?Is this plot hole unforgivable?
Hank McCoy built Cerebro but Xavier claims he and Magneto built it.Prior to First Class, both Xavier and Magneto claim to have built Cerebro, the machine that allows Xavier to monitor and find mutants anywhere on Earth. Yet in First Class, Hank McCoy originally builds Cerebro without the involvement of either mutant.Is this plot hole unforgivable?
