Spider Island (Spider Transformations)

Spider Island was a Marvel comics crossover that primarily ran in the Spider-Man titles. The premise involved the residents of Manhattan developing the same powers as Spider-Man. Their excitement proved short-lived when shortly afterward began turning into man-spiders. Almost everyone in Manhattan was afflicted by the transformation.

The fun really starts in Cloak & Dagger, issue 2. Dagger is busy studying political science with her friend Patrick when he begins feeling weird...

We move on to Amazing Spider-Man 670, which shows Spidey's boss J. Jonah Jameson succumbing to spiderhood:

In Heroes For Hire issue 1, we see a minor-league hero named Paladin mutate throughout the comic:

Lastly, we witness the transformation and reversion of Shang-Chi, star of The Deadly Hands of Kung Fu. The first three images are from issue 2; the rest are from #3. The images are taken from various parts of the story, so they will feel disjointed. To avoid confusion, I should also point out that in several images, Shang-Chi is fighting a villain who has the bottom half of spider.
