From Rob Liefeld's blog:
"...I was given an inventory story written by Howard Mackie featuring X-Factor and the New Mutants. This is well before I would introduce Cable or Deadpool in New Mutants, this was the pre-Cable cast of characters. The idea was that it could be scheduled a either an X-Factor or a New Mutants fill-in story. The focus of the issue is heavily trained on the character of Warlock and his fascination with a character named Madcap. I drew it and presumably, shortly after taking over the regular New Mutants title, the book went in such a different direction that this book was viewed as obsolete."
