The Demon (Vol.3) #9 - March 1991

"Signs and Portents" by Alan Grant, Val Semeiks, and Denis Rodier.

With Etrigan The Demon around every single month in his own book, it was only a matter of time until The Phantom Stranger showed up:

The Stranger shows up in the padded cell of a guy named Tenzin Wyatt, who is a foe of Etrigan's. He tries to reach into Wyatt's mind, but he is hopelessly lost in his own violent fantasies.

Next month, the Stranger and Etrigan face off!
