The Amazing Spider-Man Vol. 1 (1963-1998) #431

Plot

Cletus Kasady's been diagnosed with cancer, so now he really has nothing at all to lose and he's decided to take on the whole world! Too big a job for even that maniac, you cry? Too bad, Carnage has the stolen power of the Silver Surfer! This sounds like too big a job for our little arachnid to handle, but his name's on the masthead, so it looks like he'll have to!
