Synopsis for "Mind Slam"
- Synopsis not yet written
A Marvel Masterpiece from deep inside the treasure vaults can now be told! The original team of Doctor Strange, The Hulk, Silver Surfer and Namor are together again for a hidden adventure! But why was this tale lost? What happens in other dimensions stays in other dimensions, so what unspeakable secrets of the The Defenders are to be revealed? Find out at last in these pages with the illustrious words of Kurt Busiek (THE DEFENDERS, MARVELS) and the incomparable artwork of artist Mark Bagley (ULTIMATE SPIDER-MAN)!
- Morgan Nicholls, Jerry, Tyler, and Ramona are never seen, and only speak through the voices of the Defenders for part of the issue.
- Includes a letter from Kurt Busiek detailing how the issue was originally plotted by Fabian Nicieza then given to Mark Bagley to draw as a potential fill-in issue for Defenders Vol 2, but was never needed. Due to Nicieza's exclusive contract with DC at the time of this publishing, he was unable to return and script it, and since both he and Bagley had lost their original plots, Busiek was forced to create a completely new script for it using the completed artwork.
