Spider-Man, created in the Silver Age by Stan Lee has been written by various writers over the years. One of them was J. Michael Straczynski, who wrote over seventy issues of our favorite wall-crawler's adventures. His run was one of the most acclaimed by critics, controversial among fans and... screwed by Executive Meddling in the history of Marvel Comics publishing, despite the fact that Joe Quesada promised JMS very large creative freedom at the beginning.This run, along with Ultimate Spider-Man, helped remake Spider-Man into one of the flagship characters of Marvel Comics in the early 2000s after the confusing and turbulent storylines of the mid-to-late '90s. Until confusing and turbulent storylines overtook the title again... Roughly about half of the complete run was a retool of the traditional Spider-Man mythos and character dynamics, the other half being ever more outlandish crossover events between other titles, and gigantic wrestling matches between "new and edgy" plot developments and the status quo of earlier.Notable concepts brought about during the JMS run include: Spider-Man's (and many of his rogues') animal motif having potential supernatural origins, Spider-Man as a permanent and visible member of the Avengers (really a case of Brian Michael Bendis' New Avengers title bleeding over), organic web-shooters, "Iron Spider", and the public reveal of Spider-Man being Peter Parker.Followed by One More Day and Brand New Day.
JMS' Spider-Man provides examples of following tropes:
Animal-Themed Superbeing: One of the more notable additions to JMS' Spider-Man is the addition of possible supernatural influences on the very odd coincidence that Spidey and a lot of his enemies are themed after animals.
Author Tract: Mostly well-handled as JMS made Peter a teacher, which allowed him to introduce many social problems he wanted to talk about. Not so good during the Civil War, through. Well, the Civil War in general was full of confused Aesops, but Captain America quoting Mark Twain's "river of truth" speech to Spidey is undeniably awesome.
Bad Future: During time travel Peter saw one when his future self has been prosecuted by police (strongly hinting that he killed somebody) and shot to the death, while fighting policemen.
Spider Totem: Who could be a better hunter then one who had been prey? Someone who would be driven to fight back against the dark forces sent by the world, who would never stop, even though they were bigger and more and perhaps even stronger than he was. Because once having been prey, he would never allow himself to become such again. Would never surrender. Would take death before submission.
Canon Discontinuity: The 9/11 issue, as it happens in the middle of a different story and is never mentioned again. Justified in that Marvel wanted to address the disaster, and for obvious reasons could not have planned the issue to fit into the current storyline.
Card-Carrying Villain: Goddess of chaos. She actually wanted to ally herself with Peter, rather than Loki, because the former has chaotic character, while the latter wants to control others.
Characterization Marches On: JMS based his version of Aunt May on the more intelligent, sensible May glimpsed in stories by writers like Roger Stern and J.M. De Matteis, along with the fiery May seen in the Ultimate title. He also quietly let the "goofy old gal" characterization brought back by the Byrne run lapse into the past.
Cool Old Guy: Ezekiel. Right after they meet, Peter compares him to Uncle Ben.
Corrupt Corporate Executive: Luke Carlyle seems to be a little of a deconstruction as he found out that being one is too much effort and trouble and decided that becoming a typical supervillain is much easier.
Corrupt the Cutie: Digger was trying to convince Spider-Man that gangster he was protecting is trying to do this to him. Spidey, fortunately, is in a completely different mindset.
Crazy-Prepared: It's a bit of something superheroes don't talk about amongst each other, but apparently every time they meet up, most of them look for weaknesses the other has in case they would ever turn evil or something like that and have to be stopped.
Deadpan Snarker: JMS had a good handle on Spider-Man's well-known sense of humor.
The Dog Bites Back: After Spider-Man defeated Morlun, his servant, Dex, shot him to death as revenge for bad treatment.
Enemy Mine: Spidey and Octopus during a fight with Carlyle.
Spider-Man: Wait, you are helping me? Dr. Octopus: No. Hurting him.
I'm a Humanitarian: As noted in Eye Scream, Morlun ate one of Spider-Man's eyes during their second battle. Possessed as the eponymous creature, Spidey then repays this and the beating by eating Morlun's face.
Guile Hero: Spidey is not averse to defeating his opponents with traps and science-y stuff. When he needs to throw down though, he can.
Maybe Magic, MaybeI Love Nuclear Power: Totemic motive is written in a way that allows fans to choose their favorite from multiple interpretations of how Peter got his powers. Was it all a Red Herring and his powers are caused by radioactivity? Is Peter a Chosen One of Anansi? And if he is, do his powers come from magic or is he the first one that got them from science? Did the spider bite him because he was scared, or because he wanted to pass his power on to a human before dying from radiation? Or maybe it was Ezekiel who was the Chosen One and because he refused the call, all his duties and status passed on Peter? And if so, did Anansi give him the power or are they two completely unrelated incidents and Peter could become the Chosen One because of already having the necessary personality and powers? You decide. The end of that story arc has Peter discussing this issue with a South American shaman, who answers that none of these possibilities are mutually exclusive. He says that a scientist would say that the sun rises in the morning because the Earth spins, while a mystic would say the sun rises because it is meant to, and they're both right.
Refusal of the Call: Because Ezekiel refused the call, Peter has to fight with all the villains he was originally destined to defeat.
Self-Deprecation: One issue has two guards arguing that Babylon 5 sucks because you have to watch the last season for the previous ones to make sense. In another issue there is the annoying director of the "Lobster Man" movie, arguing that being bitten by a radioactive lobster is a lame origin and ordering the writer to change it to the main character being The Chosen One of a Lobster-God.
Survival Mantra: When Spidey faces off a few enemies who have proven to be far stronger than he is, he reminds himself that while he is a man, he is also part spider, and spiders are hunters.
Thematic Rogues Gallery: Lampshaded, when Ezekiel pointed out that Spider-Man has many more animal-themed villains than any other superhero. After a few encounters with mystical villains, Ezekiel was trying to use this trope as a proof that Peter's powers are magical though it's implied at least some of those mystical enemies were actually after Ezekiel himself.
Thou Shalt Not Kill: Spidey was very close to breaking this rule twice, with Morlun and Shathra both times he was spared from making the choice, because somebody or something else killed them. He actually killed Digger, but he was a zombie, so it doesn't count.
Tricksters: JMS pointed out in one story that both Spider-Man and Loki are different examples of tricksters and explored differences between them. Particularly since the Totem story arc set Peter up as a kind of successor to Anansi, the spider trickster from African mythology. Hence the parallel to Loki, the Norse trickster.
Villains Out Shopping: When Ezekiel tells Peter about Morlun, he talks about what "dark rituals" he's probably using to get ready. We cut to Morlun getting a new suit for two panels.
