For what seems like eternity Marvel has been teasing a massive conflict between the Avengers and the Mad Titan, Thanos. Finally, we have the first look at the upcoming film with a bombastic trailer. Teasing all of the powerful characters we've grown to love over the past decade, Avengers: Infinity War has a lot to live up to. In those few short minutes, there was a lot we were told about the movie. Spider-Man will be getting the Iron Spider suit shown at the end of Spider-Man: Homecoming, Loki did steal the Tesseract at the end of Thor: Ragnarok, and Vision is indeed one of the targets for the Black Order -- that's just scratching the surface.

Because of how many years this film has been set up, there's still so many more details hidden in the trailer. Coupling what we've seen with the rumors we've heard, there are eight big ones that we can practically expect to be in the film. It's easy to tell just by the clues gathered by watching the footage and coupling that with what we know about the MCU (and where the Infinity Stones are). On the other hand, there are seven other rumors that are a bit too crazy to get behind.

15 LIKELY TO HAPPEN: DEATH OF THE VISION

We'll get the easy one out of the way first. Since Vision was created with the Mind Gem and it sits in his forehead, we knew from the very beginning that Thanos would be coming to collect at some point. There's even a shot in the trailer where a member (or two) of the Black Order are trying to remove the stone from his head.

Whether they'll get it in Avengers: Infinity War or the fourth Avengers movie is up in the air at this point. Either way, we can expect to see Thanos get all six Infinity Stones at some point, meaning that Vision will lose his. What effect that will have on the robot Avenger remains to be seen, but we're betting on his death.

14 TOO CRAZY: QUICKSILVER'S RETURN

Quicksilver dead in Age of Ultron

Due to the presence of the six Infinity Stones, there has been a lot of speculation surrounding the deceased characters of the MCU; the three biggest ones being Quicksilver, Peggy Carter, and Yondu Udonta. Of the three, many people have stated that Quicksilver will probably return, whether it be from some sort of weird resurrection, or Doctor Strange traveling back in time to save him from Ultron.

We don't think this will happen because the time spent resurrecting characters could be used to focus more on the conflict of Thanos. On top of that, it would be a little ridiculous to add more members to an already impressive cast. Besides, Quicksilver probably wouldn't have much to do in the movie even if he were brought back. Maybe one heartfelt scene with Scarlet Witch would appear, but that's it.

13 LIKELY TO HAPPEN: ASGARD'S MASSACRE

At the end of Thor: Ragnarok, Asgard was destroyed by the Fire Demon Surtur and the entire planet was evacuating on a ship taken from Sakaar. However, the end credits scene showed that Asgard was not yet out of danger, as Thanos's ship loomed over them. This is apparently because Loki retrieved the Tesseract from Odin's Vault and now the Mad Titan wants it.

One shot in the trailer shows Loki holding out the Tesseract on top of dead bodies. We're betting that this means that Thanos kills the remaining Asgardians, gets the Space Stone from the God of Mischief, and sends Thor careening among the stars. For those familiar with the comic-con trailer, that's probably how Thor will end up in the Milano with the Guardians of the Galaxy.

12 TOO CRAZY: OLD VILLAINS COMING BACK

Due to how careful Thanos has been in orchestrating many of the MCU's events and conflicts, many people have speculated that all of the deceased villains we've seen over the years could be making a return for either Infinity War or Avengers 4. This idea has been somewhat supported by some of the stuff that actors and producers have said in the past.

While maybe one or two coming back (like Red Skull and Ronan) isn't completely out of the picture, bringing back all of them seems like too ambitious of a move. Not only would Marvel have to reach out to every single one of their old villain actors, inserting them in one movie that's focused on a star-studded cast of heroes would no doubt make the movie bloated in the long run.

11 LIKELY TO HAPPEN: NO BIG THANOS BATTLE

Before you start calling us dim-witted, we'll have to clarify what we mean here. Clearly, Thanos is going to come to Earth and is going to fight the Avengers. What we don't think is going to happen is that all of Earth's Mightiest Heroes will fight him at once. The reason for this is that we see multiple groups of Avengers working together in different parts of the world. Furthermore, Thanos is never shown with the completed Infinity Gauntlet.

We'd wager that all of the Avengers fighting Thanos won't be a part of the MCU until the fourth Avengers film, where the Mad Titan will have gathered all of the stones. Infinity War will probably be focused more on the Thanos Quest storyline from the comics where the villain is simply gathering the stones. The movie after that will then take a few notes from Infinity Gauntlet.

10 TOO CRAZY: SCARLET WITCH TURNS HEEL

Scarlet Witch in Age of Ultron

Scarlet Witch was introduced to the MCU as a villain. After getting powers from the Mind Gem, she and her brother Quicksilver were employed by HYDRA and Ultron to later combat the Avengers. Once it all really went bad, she eventually joined the Avengers and is a current member of the team.

One rumor suggests that it was all a ruse, and that Scarlet Witch has been a villain the entire time. This would mean that she ends up working with Thanos to get all of the Infinity Stones (perhaps it means that she's the one who gets the Mind Gem from Vision). We think it's a little ridiculous, as the movie is putting so much effort into Thanos and the Black Order as the main villains. Furthermore, there are several shots of her fighting her hardest to save Vision from the Black Order.

9 LIKELY TO HAPPEN: AN INCOMPLETE GAUNTLET

If we didn't already know that there was going to be a fourth Avengers movie, we'd definitely believe that Thanos would get all of the Infinity Stones. Because of how things are playing out, we think one of two things will happen: Thanos won't get all of the Infinity Stones right now or the movie will end with him having them all in the Gauntlet.

The reason for this is that Marvel isn't going to give us the massive battle with the Mad Titan when there's still one more film for us to see after it. This would also give an opportunity for the writers to make sure that Vision survives until the final act before he inevitably gets that stone ripped out of his forehead.

8 TOO CRAZY: HELA'S RETURN

One of Thanos's defining character aspects is that he's in love with Lady Death. This is the reason he gets the Infinity Gauntlet and goes to town on the universe -- it's all to impress her. While Lady Death hasn't been confirmed for Avengers: Infinity War, some rumors have suggested that Cate Blanchett's Hela from Thor: Ragnarok could end up being the MCU's version of Death -- she is the Goddess of Death, after all.

Why we don't think this will happen is because of the end of Thor: Ragnarok. Hela is utterly destroyed by Surtur and is on Asgard when it's blown up. There is almost no way she could've survived that. It would also make Thor's entire crusade to save Asgard entirely pointless, as she ended up surviving all of it.

7 LIKELY TO HAPPEN: THE END OF THE OLD TEAM

Black Widow, Hawkeye, Thor, Captain America, Iron Man, and Hulk have all been with the MCU for several years and longer than anyone else in the franchise. Because of this, there have been many rumors about their contracts ending and what that means for their characters during Avengers: Infinity War.

Once Phase 4 comes to fruition, it's going to signal a shift for the MCU in terms of the characters they can use -- there's no doubt about that. We'd be fairly shocked if, at least by the end of Avengers 4, that some members of the old team were no longer alive. On that note, we're expecting one death for Infinity War. In regards to whom, anyone who appeared in The Avengers is on the cutting room floor.

6 TOO CRAZY: A NEW CAPTAIN AMERICA

At the end of Captain America: Civil War, the Captain ditches his Vibranium shield and goes to Wakanda away from the U.S. government and United Nations. Many people have taken this to mean that he is no longer Captain America, and they are right. The Infinity War trailer shows us Steve Rogers seemingly looking like Nomad from the comics -- no star-spangled shield at all.

Some people have theorized that this means a new hero will take up the mantle of Captain America like in the comics (Falcon and Winter Soldier being the two primary candidates). We don't think this will happen as Marvel will want to honor the memory of Captain America and let him and the mantle itself go out in glory. Furthermore, Falcon and Bucky are still fugitives.

5 LIKELY TO HAPPEN: TWO AVENGER TEAMS

When the Russo Brothers were considering how they were going to start Avengers: Infinity War, they said that they were going to do it by splitting the team. They did this early on in Phase 3 in Captain America: Civil War. In the end of that movie, Captain America and Iron Man went their separate ways, taking specific teams with them as well.

Iron Man and his comrades operated as government-registered superheroes while Cap and his Secret Avengers went to Wakanda for sanctuary. When Infinity War takes place, we'd bet that Iron Man will be primarily leading one team while Cap and Black Panther will lead the other. Keep in mind that we don't see any of Cap's Secret Avengers interacting with Iron Man's team (save for that Scarlet Witch and Vision romance). This would also lead to them getting their butts kicked by Thanos, because they're fighting him while divided.

4 TOO CRAZY: THE CANCERVERSE IN THE MCU

The Cancerverse was an interesting part of the Multiverse in the comics. Featuring darker versions of our classic heroes, it played a major role in the "Thanos Imperative" storyline, where the Mad Titan had to work alongside a group of heroes that despise him: The Guardians of the Galaxy.

The reason we highly doubt the Cancerverse will make an appearance in the MCU is that it will be a concept admittedly difficult for general audiences to understand. On top of that, it would unnecessarily complicate an already big film. With all those characters, Marvel has to keep Avengers: Infinity War as simple as possible to allow every hero the right time to shine on the big screen. That alone will take up a lot of the movie.

3 LIKELY TO HAPPEN: XANDAR'S DESTRUCTION

Xandar Guardians of the Galaxy

If you remember back to Guardians of the Galaxy, the central conflict of that film involved the Orb which was actually the Power Gem. After the Guardians managed to get it back from Ronan the Accuser, it was given to the Nova Corps to be faithfully protected deep within the vault of Xandar.

In the Infinity War trailer, we see a shot of Thanos having both the Space and Power Gems in the Infinity Gauntlet. This means that he had to have gone to Xandar to steal the Gem from the Nova Corps. Considering the fact that Thanos isn't exactly a diplomatic guy, he went into the planet guns blazing and burnt it to a crisp just to get his precious Infinity Stone. That may even be the event that tips off the Guardians to join the fight.

2 TOO CRAZY: HEIMDALL WITH THE SOUL STONE

Heimdal Thor

There was a big theory going around regarding the MCU and the Infinity Stones. Each letter of "Thanos" stood for what contained each stone. T-Tesseract, A-Aether, N-Necklace, O-Orb, S-Scepter. You might notice that the "H" is undetermined at this point. Many people have speculated that the "H" stands for Heimdall and that he contains the last stone.

Why we're not on board with this one is that there's never been a whole lot of evidence to support this, including the Infinity War trailer. Instead, we think that the last stone is hidden in Wakanda somewhere. Why else would Black Panther have to engage all defenses and fight against the Mad Titan's army of monsters? To be fair, we also haven't had the Black Panther movie come out yet, so there's still time for the MCU to reveal a stone hiding in Wakanda.

1 LIKELY TO HAPPEN: SCARLET WITCH TRAINED BY DOCTOR STRANGE

Scarlet Witch mcu

Doctor Strange, as the Sorcerer Supreme and the omnipotent guardian of Earth, has been rumored to be the one that brings the Avengers together to fight Thanos. There are a lot of shots of him in the trailer to support this theory. However, that's not the only contribution he is said to have among the team.

There is a rumor floating around that he will meet Scarlet Witch. After seeing her instability and how that translates into her powers, he will train her to control her abilities and master them. While they're not exactly the same kind of magic-users, it'd be a great scene of pure comic book fun to see these two interacting and learning from each other. It's funny to think that Strange would be training Scarlet Witch considering that she got her powers before he did.

Which of these do you hope actually happens? Let us know in the comments!
