It took almost a decade for it to be released, but Avengers: Infinity War is a huge triumph for Marvel Studios and for every comic book fan in the world. Infinity War took the build-up of over a dozen movies and delivered into one huge event. Infinity War is positive proof of how years and years of patience can pay off. The only thing more impressive than the financial success of Infinity War is its creative one. The movie is, by far, the most comic book-esque film Marvel Studios has ever produced. It’s ambitious, daring and dazzling in its scope. A movie on the scale of Infinity War has rarely, if ever, been seen before now. However for comic book fans, the events of Infinity War should be old news.

Since the company really got off the ground, Marvel has been telling stories that challenge the imagination and reach for the literal stars. They’re not all successfully told as Infinity War. In fact, the crazier the comic book event the less coherent they usually end up becoming in the end. However, the most hardcore Marvel fans know that Infinity War isn’t the culmination of everything Marvel -- it’s just one part of a very imaginative whole.

15 THE EXISTENCE WIPE THAT LASTED

The most shocking event of Avengers: Infinity War, and the reason it'll be discussed until Avengers 4 releases, is Thanos' victory. Thanos ends up doing exactly what he wants and wipes half of existence out with the Infinity Gauntlet. Half of the life in the universe, including the lives of several gigantic Marvel heroes, is snuffed out. It's a moment that will obviously be the whole crux of Avengers 4 as the remaining heroes try to find (or bring back) the souls that were lost. Yet this is far from the first time that Marvel has wiped something from existence, and that's not even including the comic basis of Infinity War,  The Infinity Gauntlet.

In the most controversial Spider-Man story ever, "One More Day", written by J. Michael Straczynski and Joe Quesada, Peter Parker makes a deal with the devil. In exchange for Aunt May’s life Peter (and Mary Jane) sacrifice their marriage. The relationship is wiped from existence, along with public knowledge of Spider-Man’s secret identity. It was a move done to bring Spider-Man back to basics. It also, rightfully, made almost all Spider-Man fans enraged. Literally rewriting years of Peter’s history to save Aunt May, who looked like a strong wind could take her out since 1962, was deemed a terrible move. However, Marvel has yet to reverse it in any meaningful way. Peter and MJ haven’t got remarried, or have even rekindled their romance since "One More Day".

14 THE SKRULL SURPRISE

With Captain Marvel, the alien race of the Skrulls is confirmed to be making a MCU appearance. So it’s very possible that Brian Michael Bendis and Leinil Francis Yu's "Secret Invasion", will make its way into the Marvel Cinematic Universe.  "Secret Invasion" being the next event of the MCU might be the best option for the universe because the story is next-level bonkers. It could easily blow viewers' minds so much more than Infinity War -- the story is like Captain America: Winter Soldier but on a galactic scale.

For the uninitiated, the Skrulls have many powers but their main skill is shapeshifting -- Skrulls can flawlessly imitate anyone. These powers are essential to the big hook of "Secret Invasion". The crossover event, which spans the entire Marvel Universe, reveals that countless Marvel heroes are aliens in disguise. The eponymous invasion has been years long process that involved Skrulls taking over the identities of several heroes and weeding their way into places of power. The Marvel Cinematic Universe that revealing one, let alone several, heroes that fans have come to know and love have been aliens the whole time would be the boldest move possible. Yet if pulled off successfully, it would wipe out all memory of anything Thanos did during Infinity War.

13 NO MORE MUTANTS

Scarlet Witch is one of the most underrated characters in the MCU. Wanda Maximoff is also one of the most powerful heroes in the Marvel Universe, if not all of comics. There’s a reason that Infinity War made a point of showing how powerful Wanda was when she finally joined the final battle in Wakanda. Though it’s never really made it into the MCU, Scarlet Witch can manipulate reality. This resulted in the event Brian Michael Bendis and Olivier Coipel's "House of M" which completely changed the fabric of the main universe. "House of M" occurred because Scarlet Witch was mourning the loss of her children and wanted to bring them to life. Instead she created a whole new reality, where mutants not humans were the dominant race.

A few mutants and other heroes end up remembering the life they had before the universe was recreated. They storm the complex that Wanda is living in with her father, Magento, and brother, Quicksilver and reality is restored … mostly. Wanda, horrified, at her actions restores reality but with “no more mutants,” stripping thousands of their powers. It’s an event that the MCU would never be able to pull off completely, due to the lack of X-Men. Still it’s probably a good thing for everyone that Wanda was killed in Infinity War, because Scarlet Witch’s grief over Vision could’ve changed everything.

12 THE BIGGER (AND BADDER) CIVIL WAR

The MCU version of "Civil War" was not a perfect recreation but it hits on most of the big moments. It just so happens that the comic book sequel, Brian Michael Bendis and David Marquez' "Civil War II", is even nuttier than the events movie fans saw in Captain America: Civl War or Infinity War. This doesn’t mean that "Civil War II" is better than the original. In fact, it’s the exact opposite. "Civil War II" is a bit of a mess and was clearly done to capitalize on the popularity of the movie. There are some good bones to the conflict -- it has some moments that would make even Thanos blush.

The conflict of "Civil War II" begins due to an Inhuman, Ulysses, who has a nightmarish vision of the future. Ulysses’ visions become the flashpoint for a conflict between Captain Marvel and Iron Man. The two respond in two very different ways for how to deal with the visions. Captain Marvel is obsessed with changing the future, while Iron Man doesn’t even believe that Ulysses’ visions are accurate. It’s an unnecessary complicated tale but the events themselves are pure insanity. Bruce Banner is murdered by, of all people, Hawkeye -- who is acquitted of the crime. Miles Morales is arrested for a crime he will commit. Lastly Iron Man dies a metaphorical death being put into a serious comatose state. "Civil War II" does lack emotion but not dramatic moments.

11 THE REAL MOST AMBITIOUS CROSSOVER EVENT OF ALL TIME

Infinity War was marketed as “the most ambitious crossover event in history.” This led to a ton of internet mocking and some fantastic memes. Infinity War is a huge event but there’s other crossover events that fans would like to see too, like the MCU and the DCEU crossing over. Stragnely, the Marvel and DC Universes have already interacted in the comics.

The '90s were a rough time for comics in general but especially with DC and Marvel. To help fight flagging sales, the companies staged a crossover that saw their universe get all mashed together. The 1996 series called simply titled, DC vs. Marvel did exactly what it claimed to do. Heroes and villains across both universes ended up facing off. Storm faced off against Wonder Woman, Superman fought The Hulk and, for whatever reason, Robin faced off against The X-Men’s Jubilee. DC vs. Marvel was shameless fan service. It wasn’t particularly that well-written or drawn. All the outcomes of each match was decided by fans, which resulted in some very strange victors. The notable thing about DC vs. Marvel is how singular it is in history. A crossover like it hadn’t happened before and likely never will happen again. However if, by some miracle, Superman and Iron Man interacted on the big screen it would blow the box office of Infinity War so far out of the water.

10 THE WALKING MARVEL DEAD

When The Walking Dead TV series launched in 2010, zombies were at the height of their monster popularity. Since the premiere of The Walking Dead, zombies have since fallen in terms of their pop culture footprint (along with The Walking Dead) itself. This is because the premiere of The Walking Dead really represents the climax of zombie popularity than the launch of a new era. For years before The Walking Dead TV series showed up, zombies were popping up all over in pop culture, especially in comics. The comic series for The Walking Dead began in 2003 and quickly grew in esteem. This resulted in Marvel trying to cash on the craze by hiring the series’ scribe, Robert Kirkman, to bring zombies to the Marvel Universe.

The collaboration was simply christened "Marvel Zombies". The goals of the miniseries were just as straight-forward as the name. An unknown hero crashes to Earth and slowly infects the entire world with a zombie like disease. The slight twist that the zombie versions of the Marvel heroes retain their intelligence. They still look and sound like themselves, they just desire human flesh. It’s all very silly and disposable. The comic lacks almost all of the depth of Kirkman’s other zombie epic. It would also never work on the big screen but it’s fun to imagine a world where Marvel Studios loses its mind and decides "Marvel Zombies" needs to be made.

9 THE NOT SO SECRET WARS

Avengers: Infinity War brings together (nearly) every hero in the Marvel Cinematic Universe for the big event. Even though Hawkeye, Ant-Man and every superhero from every Marvel TV series is largely ignored, Infinity War is still huge. However, Infinity War is just bringing together one universe under a single banner. The 2015 comic event, "Secret Wars", by  Jonathan Hickman and Esad Ribić brrought together (nearly) every universe that Marvel had ever created for one big event. "Secret Wars" is based on the mid '80s event of the same name but manages to be far ambitious. The aim of "Secret Wars" was to  clean up the continuity Marvel Comics and have them appeal to a newer audience. Although the story itself is so bananas, "Secret Wars" only works for the most hardcore fans.

The premise of Secret Wars is that all the various versions of the main Marvel Universe (Earth-616) are gathered together to one world, the Battleworld. The main heroes of Marvel fight with the heroes of the Ultimate Universe. The Marvel Zombies face off against the world of Age of Ultron. It’s a crossover of epic proportions and did end up changing the Marvel Universe forever by the end.Miles Morales was integrated into the world of Earth-616. Ultimate Thor met The Unworthy Thor and Jane Foster Thor and Doctor Doom did a lot of monologuing.

8 THE INFAMOUS HYDRA CAP

Captain America doesn’t give much screen time in Avengers: Infinity War. Steve Rogers gets to go head-to-head with a fully powered Thanos and he almost wins. Yet the main original Avenger of Infinity War is still Tony Stark, with an intergalactic assist from Thor. However at least the Cap in Infinity War is recognizably Cap. He’s still the purest example of a true hero. The same can’t be same of Captain America in the comics, at least in recent memory. It’s now, mercifully, over but for nearly a year the main version of Captain America in the Marvel Universe was a secret Hydra agent. This Captain America, due to some comic book weirdness, was evil and had always been evil. Every heroic thing Hydra Cap did was just a cover for Hydra. The actions of Hydra Cap came to a head in Nick Spencer's "Secret Empire", which saw Hydra Cap rule America with an iron fist.

"Secret Empire" angered a lot of fans. Not just for how it twisted Captain America’s mythology but for its lack of consequences. The “real” Captain America eventually came back to defeat Hydra Cap and the one major death, of Black Widow, has since been reversed. However, the outrage that "Secret Empire" caused in the comic community would be nothing compared to how mainstream audiences would react if the MCU Steve Rogers was suddenly a Hydra agent.

7 THE MIGRAINE INDUCING CLONE SAGA

One of the most appealing factors of Spider-Man in the Marvel Cinematic Universe is his relatibility. Peter Parker is simple and approachable -- he’s just a kid with superpowers. It’s almost impossible to not empathize or connect with him, whether it’s in Spider-Man: Homecoming or Infinity War. "The Clone Saga", the infamous story arc that ran from 1994 to 1996, is the opposite of Peter’s humble MCU status. Weirdly, like some of the other most disastrous Spider-Man stories, "The Clone Saga" was supposed to make the character more streamlined. Spider-Man’s first clone, Ben Reilly, was introduced to give the original Peter a chance to retire and live a peaceful life. This would’ve been fine if Marvel had stopped right there.

Yet "The Clone Saga" dragged on and on, with more and more Peter Parker clones showing up. To keep track of all the plots in "The Clone Saga" requires a detail chart, if not a PhD. The Clone Saga threw out so many twists at the audiences all of them seemed to contradict the last. Everything crazy that could’ve happened Spider-Man did. There was no through line. There were way too many creative cooks in the kitchen Obviously, Avengers 4 will find a way to bring Peter back to life. If that resurrection method is a clone, everyone should start getting very, very nervous,

6 THE ONLY THING TO FEAR

Avengers: Infinity War was kind to the original Avengers line-up. Captain America, Thor and Iron Man all survived. They will, most likely, be crucial to saving the day and putting the world back to rights in Avengers 4. The comic arc, "Fear Itself" wasn’t nearly as kind to heavy hitters of the Marvel Universe, especially Cap and Thor.

Captain America and Thor feature heavily in the crossover event written by Matt Fraction and illustrated by Stuart Immonen, Wade Von Grawbadger, and Laura Martin. Ultimately "Fear Itself" is more of a Thor story that ties into Cap. Before Fear Itself begins Asgard has been destroyed, similar to Thor: Ragnarok. The Asgardians are trying to find a new home on Earth. However, a little bit too of Asgard comes to Earth, as the planet quickly becomes under siege from powerful god like beings. In a situation reminiscence to Infinity War, after an initial defeat, Thor rallies and saves the day. Yet the effort causes him his life and for years to come Thor would stay deceased. During the arc it also appears that Captain America, who was Bucky Barnes at the time, dies. However, it was revealed that Bucky’s LMD was the one that died. The real Bucky went back underground and became the Winter Solider once again. Infinity War’s ending is a downer but it would be so much more depressing if Thor and Cap both died.

5 THE MOST DRAMATIC MURDER INVESTIGATION EVER

Avengers: Infinity War begins with destruction and doesn’t let up. It’s a thrill ride from the beginning, which opens on Thanos murdering Asgardians and doesn’t slow down till it’s very final moments. The Jason Aaron's "Original Sin" has a rather simple start. It begins with a murder investigation and then throws everything but the kitchen sink at its heroes. The inciting death of Original Sin is a big one. Uatu the Watcher, who seemed truly immortal, is mysteriously butchered. Various teams of heroes try to search for the culprit and they uncover some shocking truths. Little of which has to do with Uatu’s death.

Uatu’s name of The Watcher is litera. He has observed everything throughout time. Uatu, or more accurately his eyes, contain all knowledge in the world. Uatu’s eyes are stolen after his death and that results in pretty much everyone’s secrets coming out and chaos reigning. Thor loses the worthiness to wield his hammer, Professor X’s will was discovered and that's are just the beginning.By the end of "Original Sin" it’s revealed that a much older version of Nick Fury is behind all the madness. He killed Uatu for his knowledge and he’s been pulling strings in the universe for years, using LMDs to appear much younger. Samuel L. Jackson’s Nick Fury has shied away from the spotlight Infinity War would’ve been much more insane if the man with the eyepatch was revealed to be some evil mastermind

4 THE THANOS COPTER

Infinity War isn’t Thanos’ first appearance in the MCU. He popped up at the end of the first Avengers, played a semi-significant role in Guardians of the Galaxy Vol. 1 and appeared, once again, in the credits during Age of Ultron. However, Infinity War might as well be treated as Thanos first official appearance. The movie does almost all the heavy lifting in introducing Thanos and establishing his character. It’s a tremendous first effort as Thanos is the undeniable star of Infinity War. It might sound impossible but one of Thanos’ earliest appearances is even more outlandish than Infinity War. However, that isn’t exactly positive. Thanos appearance in the 1979 Spider Super Stories #39 is iconic but for all the most laughable reasons. The story sees Thanos invade New York City just like in the opening of Infinity War. However, Thanos’ invasion vehicle isn’t controlled by the Black Order and isn’t a terrifying space ship in the shape of a wheel. No, Thanos comes to Earth in a dinky helicopter.

From the unwieldly helicopter, which bares Thanos’ own name, The Mad Titan faces off against Spider-Man and The Cat (otherwise known as Hellcat AKA Patsy Walker). Thanos is laughably inept. He ends up being apprehended by, not a small army of supeheroes, but regular NYC police officers. Evidently, Iron Man didn’t need Dr. Strange, Star-Lord or anyone else in Infinity War. He just needed some of New York’s finest.

3 THE INVINCIBLE IRON BOY

Iron Man is complicated figure in the MCU. Thanks to Robert Downey Jr.’s amazing performance, Tony has always been watchable. The story of the MCU is one of redemption for Iron Man as Tony’s been selfish, arrogant and just a plain jerk. Yet MCU Tony’s never been quite evil. Tony flirts at the edge of the morality but never quite goes over it. In mid-'90s the main Tony Stark of Earth-616 did cross the line. Similar to the Hydra Cap story, it was revealed that Iron Man had always been an evil double agent. As a result, he went on a path of destruction and The Avengers were at a loss at what to do. They did the only sensible thing available to superheroes. They went into an alternate universe and plucked out a younger Tony Stark who was never corrupted (no, wait that's insane).

The ridiculous hope was that this young Tony would remind older, eviler Tony of his humanity. It didn’t work. The evil Tony went too far and had to be neutralized. Rather than just put the teenage Tony back into his time, teen Tony stuck around. He became the Iron Man of Earth-616 for an extended period of time. The clock is ticking on Robert Downey Jr. playing Iron Man. However, the MCU will probably never do something as insane as replace Tony with a younger, hipper version. At least that’s the hope.

2 MS. MARVEL GIVES BIRTH TO HER OWN SON

Captain Marvel was finally teased at the end of Infinity War. Carol Danvers will get her long overdue solo movie in 2019’s Captain Marvel and be the first female-led superhero movie for the MCU. Sadly, the existence of Captain Marvel's movie alone is unbelievable given how male dominated the Marvel Cinematic Universe has been. However, it’s highly unlikely that the movies will ever take Carol to as ridiculous and gross a place as the comics. In Avengers #200, Marvel decided to tell a big story for the landmark issue. The story, written by James Shooter, George Pérez, Bob Layton and David Micheline with art by Pérez succeeded in being memorable. Yet not much else can be said of it in a kind light.

The story sees Ms. Marvel, who would one day become Captain Marvel, become mysteriously pregnant and give birth to a full-grown adult son in a matter of days. It’s eventually revealed that the father of the baby is the baby itself. Marcus Immortus, was a powerful entity who existed in a state of limbo. He ensnared Carol Danvers. Then without her consent or knowledge, Marcus impregnated Carol with his own essence so he could escape limbo. The story is one of the most controversial and reviled tales in Marvel history. It’s as crazy and it is disgusting.  The only good thing about is that everyone seems to agree it was a terrible mistake and has ignored it.

1 GWEN AND GOBLIN SPAWN

The Marvel Cinematic Universe’s Peter Parker is at the start of his superhero career. There’s still so much more for Tom Holland’s Spider-Man to do (at least as long as Sony and Marvel play nice with the character). The obvious future of Spider-Man is what makes Peter’s death in Infinity War so unbelievable, even if it was heartbreakingly rendered by everyone involved. Yet if MCU’s Peter is anything like the comic Peter, he might be better off staying dead. A lot of Spider-Man fans know that Gwen Stacy was Peter Parker’s first love. Gwen died when the Green Goblin, aka Norma Osborn, attacked her and Peter (failed) to save her. Few know that Gwen and Norman Osborn have a more complicated and disturbing history.

In the 2004 story arc, again written by J. Michael Straczynski, it was retconned that before Gwen was killed, she had an affair with Norman Osborn. It was creepy, as everything with Norman is, but completely consensual. The affair produced two twins. Gwen didn’t want Norman to have anything with their children but that didn’t change the fact that they, for no apparent reason, had slept together. Through all manner of comic book weirdness, the kids grew to the age of young adults in no time and the son, Gabriel Stacy, became the Grey Goblin. Thankfully both children have seemingly disappeared from canon. Neither Gabriel or his sister Sarah have been seen since 2010. Yet they are still terrible, illogical comic canon.
