The day of the Defenders has come! Roy Thomas joined his Titans Three of the Incredible Hulk, the Sub-Mariner and the Silver Surfer together with Doctor Strange to create comics' greatest "non-team," the Defenders!

But when they encounter heroes of a more conventional stripe, it's war - the watershed hero vs. hero Avengers/Defenders War, no less!
