It’s a Radio Play- by Greg Weissman, the guy who CREATED Disney’s Gargoyles!! He worked on The Sensational Spider-Man cartoon (and that’s the version used here) so he knows those characters too. This is not canonical to either series -not yet,anyway, though now that Disney owns Marvel, they’d be dumb if they didn’t do something like this sooner or later.
Anyway, I read this and It Rocks!! Really, if you love either series, give this a try. Here are the links to the script (no voicing, sadly):

Minor warnings: there is some swearing and some Christian references- nothing really bad, but, gotta give fair warning. Also, you may want to save these links, as this makes for LONG reading. 
Enjoy!
