Jim Shooter, from sometime during his reign as Editor-in-Chief at Marvel (Jan 1978-Feb 1987)

He seemed to deliberately cultivate an image of himself as an imperious boss. But as demonstrated by many of the fun projects he oversaw (FANTASTIC FOUR ROAST, MARVEL FUMETTI book, HOWARD THE DUCK magazine 5 that portrays him firing Marv Wolfman, similar photos and behind-the-scenes in HULK magazine and Marvel Bullpen bulletin pages) it seems like he had a fun side too.
