"Spider-Man never made you special. Being Peter Parker makes you special!"
— Mary Jane Watson
Peter Parker's life has really turned a corner. He has a great new job, is a well respected super-hero, in a new relationship with Carlie Cooper and getting along well with his ex, Mary Jane Watson. Things then take a turn for the strange when Carlie reveals she has the same powers and abilities as he does. And she's not the only one. New Yorkers everywhere (except for MJ) are developing spider powers. All courtesy of The Jackal and his secret benefactor.The major Bat Family Crossover of 2011 for Spider-Man, the majority of the story was seen running primarily through the Amazing Spider-Man book with some important side chapters appearing in the recent Venom ongoing as well. There were other loosely connected tie-ins with Black Panther and Herc, as well as mini series and one-shot tie-ins created for the event in the form of the Deadly Hands of Kung Fu, Cloak & Dagger, Deadly Foes, Spider-Woman, Amazing Spider-Girl (Anya Corazon), Heroes for Hire and The Avengers.
Spider-Island provides examples of the following tropes:
Bat Family Crossover: The basic premise of the arc is that everyone in New York gets Spider-Man's powers.
Big Bad: The Queen, a semi-obscure villainess from a single storyline during Avengers Disassembled.
Big Damn Heroes: Peter Parker pulls one off early in the story. Mary Jane pulls one off towards the end of the story.
Body Horror: The eventual fate of all those with the "Spider-Flu" is to transform into a giant spider monster.
Boss Battle: The last issue is literally called "Boss Battle" as Spider-Man, the Avengers, X-Men, Future Foundation, the rest of the remaining super heroes and Mary Jane make a final stand against the villain for the fate of New York and the world.
Kaine was also brainwashed by The Jackal as his faithful servant.
Brought Down to Normal: Inverted. Everyone else in New York has all the powers Peter has. That is, until they become giant man-spider monsters.
Played straight with Eddie Brock, who gives up being Anti-Venom in order to cure those infected.
Also played straight with Mary Jane, who was cured of the infection before she mutated into a giant spider monster.
Call Back: Post-Face-Heel Turn, Kaine notes to Spider-Man that he hates wearing Peter's classic costume because the last time he wore it, he died & woke up with some weird new powers. Spidey notes that he can relate to that, that very thing having happened to him during "The Other".
After a 10-Minute Retirement in Amazing Spider-Man #50 Spider-Man tells Jonah that he was out recruiting, and that he was "gonna fill the whole city with Spider-Men!"
With The Jackal and Kaine involved in a plan to create new Spider-Men, the connections with The Clone Saga are heavily lampshaded. Among other call-backs, many of the background characters wear copies of the Ben Reiley Spider-Man and Scarlet Spider costumes instead of the classic Peter Parker costumes.
Comes Great Responsibility: After finally gaining spider powers, Mary Jane states that she understands that her powers come with a great responsibility.
Covers Always Lie: One of the covers shows Bucky in his Captain America outfit among the heroes who join Spidey in the story, but he never appears in any capacity within the comic.note Likely, because in the other big crossover event, Fear Itself, Bucky was kinda dead.
Another cover shows all the heroes in variant Spidey costumes, which never happens. It would be just about acceptable as a symbolic representation of them all gaining spider-powers, except the virus doesn't affect anyone who already has a superpower.
Dude, Where's My Respect?: At the very end, Eddie Brock, formerly Anti-Venom, is being called the true hero of Spider Island, and Spidey is rightfully peeved. This is of course before Mary Jane shows him the Empire State Building, lit up in red and blue.
Foreshadowing: Carlie reveals her powers to Peter not long after they first have sex and Peter says that this never happened with Mary Jane despite them being together for years. Reed Richards later hypothesizes that the reason MJ's contraction of the infection was so slow was because she was with Peter for years.
Giant Spider: Those infected with the Spider-Flu transform into a human sized spider. The Queen herself transforms into a 28 story tall spider monster during the final battle.
Genki Girl: Carlie is VERY excited to have spider-powers.
Getting Crap Past the Radar: Reed Richards hypothesizes that the reason Mary Jane's infection was so slow was because she was "so... close..." to Peter for years. Once Peter and MJ encounter each other during the final battle, MJ starts to explain Reed's theory when Peter summarizes it as because they "shared a toothbrush."
A God Am I: The Queen, once she achieves her full power. Completely justified considering she takes out (and by "take out" we mean half-vaporized) the Red Hulk & Wolverine in one move.
God Save Us from the Queen!: Adriana "The Queen" Soria from 2004's The Spectacular Spider-Man Vol 2'' makes a comeback, this time teamed with the Jackel to infect all of New York with her spider-virus.
Gondor Calls for Aid: Peter publicly calls out to the good New Yorkers for help against the evil spider powered New Yorkers.
He's Back: Fans of the classic Eddie Brock version of Venom were thrown a bone when the symbiote happily ditched Flash Thomson to reunite with its second host... for three panels, during which Flash pleaded with the symbiote to return to him and reminded it that Eddie would constantly resist its control. On a more permeant, Kaine came Back from the Dead and eventually wound up inheriting the title of the Scarlet Spider.
Hive Queen: The Queen hijacks the Web of Life to turn all of New York into her spidery minions.
Infant Immortality: Several children are shown getting spider powers before - usually played for laughs, and at one point for a heartwarming story. When the people infected start turning into monsters and fighting the heroes, no children are to be seen. Several children are shown starting to turn, but are all cured in some way or another before they can do so completely.
Inferred Holocaust: When people start turning into spider monsters and going berserk, it's constantly brought up by the characters that these are still innocent people and that they should be treated with non-lethal force. Spider-Girl, in particular, encounters The Hand, The Hobgoblin and a whole slew of anti-Spider cultists killing scores of people-turned-monsters indiscriminately, and throughout the entire arc it's implied several times that a lot of innocents were killed while under the control of the Queen.
Magic Pants: Lampshaded in "The Naked City". As the superheroes spend so much time in skintight outfits they no longer have any real body shame, they instead comment on things like Misty Knight still having her headband and T'Challa's beard vanishing but his hair staying the same length. Hawkeye cites Hulk's famous pants and actually tells them to Hand Wave it.
Nice Job Breaking It, Hero: Peter Parker "outing" himself as having spider powers to rally the civilians broke a spell placed by Doctor Strange that would prevent anyone from figuring out he's Spider-Man. To clarify, people can now learn who Spider-Man is, but they haven't remembered who it is following Peter unmasking during Civil War.
Peter's extensive use of Doctor Octopus's technology near the end is what allowed Doc Ock to later swap minds with him.
Prophecy Twist: Peter Parker is prophesied to kill The Queen... but the prophecy didn't say anything about which Peter Parker, now did it?
Rousing Speech: The page quote is part of a rousing speech Mary Jane gives to Peter. He actually thinks the speech was pretty terrible but it still did its job.
Peter also gives one to all of New York, calling upon the people of the city to band together and help fight the villains.
Ship Tease: Between Peter and Mary Jane, as MJ declares her love for Peter in the final battle, though she makes sure Peter doesn't hear her out of respect for his relationship with Carlie. Considering Carlie breaks up with Peter a few hours later, hindsight is not her strong point
Took a Level in Badass: Spider-Man, having lost his Spider Sense a few months earlier, is shown training with Shang Chi at the start of the series, since he could no longer rely on Spider Sense & his agility to win fights, and now had to actually learn how to do so. During the final act of the story, Horizon Labs manage to find a way to restore his Spider Sense, meaning that Spider-Man now has actual martial arts expertise to back up his powers, and swiftly turned the tables in his fight with the now outmatched Kaine.
What the Hell, Hero?: Carlie breaks up with Peter when she realizes he is Spider-Man and their whole relationship was a lie.
