The final trailer for X-Men: Apocalypse debuted with a bang - it revealed the reason for Mystique’s (yet again) prominent role in the movie; it revealed that a certain speedster has become aware of his heritage; AND it revealed that a certain fan-favorite mutant will return.

However, despite its being the final trailer, we still have quite a few unanswered questions. For example, even if we know what kind of powers Apocalypse possesses, we still have no clue why he lay dormant for all those consecutive millennia.

And don't get us wrong - that is a good thing. Sure enough, this latest trailer might have revealed a bit too much (that returning character). However, other than that, it still kept quite a few surprises for us to enjoy when X-Men: Apocalypse arrives on the big screen.

All of that being said, this list is all about the unanswered questions, the things that we already know, as well as how everything might unfold. So beware - there could be quite a few spoilers here!

Wolverine

Let's get this out of the way - Wolverine was rumored to be appearing in X-Men: Apocalypse well before the movie started shooting. And that’s because Bryan Singer released a piece of concept art showing a character assuming the mutant's posture in front of what seemed to be a giant spaceship.

But, until now, that was just a rumor. Now we know for sure that Wolverine will at least cameo in the movie.

When Days of Future Past ended, Wolverine still had his bone claws. As it was revealed at the end of the movie, he was captured by Mystique, who was disguised as William Stryker. The final X-Men: Apocalypse trailer revealed that he had already received his adamantium claws.

After the release of the final trailer, Bryan Singer said that the Wolverine scene is a pivotal one, and it isn't the only one to feature the no-nonsense mutant. So we can assume that the character's origin story won't be told on the big screen once again.

But this statement sparked some other rumors, namely that the clawed hand we see in the trailer doesn't belong to Hugh Jackman, but rather to a new Wolverine. If it is so, then we don’t know what to believe. This could be a genius move, nonetheless, since it would separate the pre-Days of Future Past timeline even more from the post-Apocalypse one.

And it would be the premise of one helluva final Wolverine movie starring Hugh Jackman!

Professor X

Like many times before in the original trilogy (perhaps too many times), Professor X seems to be taken out of the equation pretty early in the movie. Which leaves a vacant spot - who will lead the X-Men against Apocalypse and his horsemen?

But let's not get ahead of ourselves just yet. James McAvoy returns for another X-Men movie, which won't be his last - though we expect his role to diminish.

In the trailers, he is depicted as being both fascinated and fearful at the power Apocalypse possesses. And he should be - in one of the scenes, he is bashed like a rag-doll by the uber-powerful mutant. Is that a scene taking place in reality, or is that a battle of the psyches?

We're inclined to believe that the attack by Apocalypse all happens in his mind. And it isn't just the fact that he can walk that gives it away - it is also Mystique's scream that acts as a hint, since she’s nowhere to be seen.

We can also assume that this scene will be followed by the destruction of the mansion. As seen in the trailers, Havok will project quite a blast while in Cerebro, most likely trying to free Professor X from Apocalypse's grasp. And this won't end too well, for the mansion and for Havok himself (Beast looks pretty upset at one point on the trailer).

And this is when all of the students are in immediate, grave danger.

Enter Quicksilver

Quicksilver was the highlight of Days of Future Past, even if he was underused - once scene was all that was needed to make him a fan favorite. Apparently, as Bryan Singer teased, a scene with him in X-Men: Apocalypse will top the kitchen scene from the previous X-Men installment.

And this is the one, as seen in the trailers: when the mansion explodes, Quicksilver can be seen running as if stepping on the flames. We can assume that he’s doing this to save the students.

There is one other big reveal in this final trailer - Quicksilver already knows who his father is. The promotional interviews said that he is in the search of his father and we all assumed that he is searching for his father’s identity. It is pretty clear that he is actually looking for Magneto.

And here comes another parent-offspring relationship from the comics"¦

Mystique

As we mentioned, after Apocalypse disables Professor X (we don't know if it’s a physical or mental disability), Beast asks Mystique to fill in as the leader of the X-Men. To be noted: She is one of the few mutants seen by the entire world during the Days of Future Past events.

And that has transformed her into a living legend. Which is best showcased when she rescues Nightcrawler from the undergrown battling ring.

But that scene, in which Nightcrawler exclaims, “You're her!”, can be seen from a different perspective, as well. In the comics, Nightcrawler is the son of Mystique. So what if he is surprised to see his own mother? After all, between the events of First Class and Days of Future Past, Mystique spent quite a lot of time alone with Azazel.

Do you think X-Men: Apocalypse will go in this direction with the Mystique/Nightcrawler story?

Apocalypse

Trailer by trailer, the backstory of Apocalypse becomes a bit clearer. We already knew that he is an ancient mutant who has the ability to steal powers from other mutants. And now we’ve seen how he does it.

Nonetheless, we still don't know quite a bit. For example, is the Oscar Isaac form his initial form? Why did he lay dormant for so long, and why didn't he just switch to another form? So there is still this big mystery that needs to be solved - when X-Men: Apocalypse is released, of course.

And there is one more interesting thing about this character. In the comics, Apocalypse becomes even more powerful by using Celestial technology. Will this aspect be explored in the movie as well? We believe that it will - first of all, we have that piece of concept art showcasing Wolverine. And then there is also this scene from the trailer, in which a giant dome can be seen in the background (built, most likely, by Apocalypse himself, from the molecules of everything he has destroyed).

Magneto

We’ve said that Apocalypse gathers followers by exploiting the mutants' weaknesses - Storm was an orphan raised on the streets; Angel had to fight in illegal underground clubs; while Psylocke sees the powerful villain as a means to an end (she is the hedonistic member of the group).

As far as Magneto was concerned, the promotional interviews revealed that he went into hiding after the events of Days of Future Past, and that he even found someone to love. The final trailer reveals that it was more than that, since Magneto says that he lost his entire family - we assume that some kids were also involved.

And this opens up a possibility. We do know that this is yet another turning point for the character - if he had been left in peace, he wouldn't have joined Apocalypse. So the reason he forgot all about his friendship is because his family has died.

But what about Quicksilver? He’s family,too. Can Magneto leave Apocalypse after finding out that he still has a family? It’s pretty predictable, and that’s why it could be disappointing if that happens.

The trailers also suggest that he has evolved his powers even further than before. The scenes of destruction can his doing, since now he can control even the tiniest metal atoms. But there is a particular scene in which he stars, and of which we can make no sense.

Check out the two pics below, and you will also see that he is trying to contain an explosion and not defend himself from it.

What do you think?

Jean Grey

The first X-Men trilogy can be said to have been built around Jean Grey's transformation into the Phoenix. Is this the beginning of a new (and proper, this time) adaptation of the beloved X-Men story arc?

Bryan Singer has teased this possibility on several occasions, even if he said that he'd be interested in bringing other powerful villains to the big screen, as well (namely Proteus). But, most recently, he did say that some scenes in X-Men: Apocalypse will show that there is a hidden power inside Jean Grey, a power that always tries to break loose.

Did we just see that in the final X-Men: Apocalypse trailer?

We believe we did. While attention is stolen by other newcomers (Psylocke, Storm, and Cyclops), there is a particular scene in which Jean Grey looks fierce, as if realizing that she is the only one that can put a stop to it all. And if her story does lead into the Dark Phoenix Saga, she is, indeed, the only one among the X-Men who can defeat him.

While seeing villains like Proteus on the big screens is a must, seeing the Dark Phoenix Saga done right is a muster (if we may say so).

Global destruction

In the beginning of the final trailer, Xavier says that things have been better. But that doesn't necessarily equate with having peace - the mutants are still in hiding and are still being exploited (case in point, Angel being forced to fight for his survival) and we can presume that the human population isn't too keen on sharing the planet (after all, this has been a central point of all of the X-Men movies thus far).

But this apparent peace is revealed in its true nature by the arrival of Apocalypse. And there are the shots in which we see the nukes flying - are they reality, or is it just a bad dream waiting to happen (as suggest by the trailers)?

And there is global destruction. And just like with any movie, the biggest of all landmarks are being destroyed - in this case, Sidney's Opera House. While we are glad the Golden Gate Bridge is finally taking a break from being destroyed, we are wondering what in the world Apocalypse is doing down under, when there are plenty of other (more famous) landmarks in the world.

Do you have any idea?

The other X-Men: Apocalypse mutants

Back when X-Men: Apocalypse started filming, quite a few mutants were revealed to be in the film. This trend has continued up until the past few days, when Bryan Singer revealed that even Blob will make an appearance (we last saw him in X-Men Origins: Wolverine).

It is safe to say that, other than the X-Men featured in the trailers and the horsemen, all the other mutants announced (for example, Jubilee) will have minor roles. Obviously, this is fan service, pretty much like in Days of Future Past, with all those mutants killed at both the beginning and end of the movie.

Which is a good thing, since the movie won't be overstuffed with characters.

Obviously, naysayers already believe that it is overstuffed. But it’s pretty clear that some of the characters have main roles (Magneto and Mystique, for example), while the others are in supporting roles.

Theory

There is a particular scene that may suggest that this is the last time we see a certain mutant (at least until the inevitable reboot) on the big screen. This has actually been corroborated by the actress who plays the mutant, who happens to be Mystique.

As seen in one of the clips released, she will engage Apocalypse in close quarters. And that is obviously a bad idea, since she isn't overly superhuman, especially for a superhuman character - at least, we can say that she is not in the same league with Apocalypse. And Jennifer Lawrence did say, at one time, that she may be done with the X-Men after X-men: Apocalypse (yes, she said differently after some time passed, but still…).

So, could this be her swan song? We believe it is, especially since she has a much more prominent role than ever before (even bigger than in Days of Future Past, when she actually fueled the entire plot). So we may see her heroically perish at the hands of Apocalypse.

Furthermore, given her past relationship with Magneto, her death will also convince him that Apoc is as bad for the mutants as he is for the humans - so, he will rebel. Because, let's face it, Magneto AND Apocalypse are just too much to handle for a team of inexperienced X-Men.
