X-Cutioner's Song - Stryfe's Strike File

Stryfe's Strike File was the name of a 1993 X-Men one-shot written by Fabian Nicieza and Scott Lobdell. It included several years worth of foreshadowing of Lobdell and Nicieza's X-Men plotlines, most notably the Legacy Virus plotline. The comic framing device was that the files in the one-shot were on a CD-ROM found at Stryfe's base by Bishop and handed over to Xavier without telling anyone else about it. After nearly two dozen pages of text and picture files, most of which were taken from the trading card inserts included in the individual issues of the crossover, the book ended with a closing sequence where Xavier destroys the disk rather than showing it to Cyclops and Jean Grey.

The book contained entries for Graydon Creed, Threnody, and Holocaust prior to their first appearances elsewhere. Graydon Creed would appear as a villain two months later, Threnody would appear eleven months late, yet Holocaust would not appear in the X-Men comics until the alternate reality Age of Apocalypse storyline. The version found in that storyline differs from the one found in Stryfe's Strike File in that the Age of Apocalypse Holocaust requires a containment suit and is very talkative while the Holocaust in the files does not need a containment suit and is a silent killer.
