"The MARVEL-Phile" column in Dragon magazine complemented the Marvel Super Heroes role-playing game from the 1980s by providing ability ranks and power descriptions for comic book heroes and villains. Dragon #163 included a game conversion for Nebulon, a quintessential foe of the Defenders.
The well-researched column noted how Nebulon jumped from a modest Popularity score to Monstrous worldwide popularity as head of the Celestial Mind Control Movement).
The section on Nebulon's powers detailed the game mechanics that might cause the shape-shifting Nebulon to revert back into his six-tentacled true form.
Lastly, the section on the character's history alerted readers that including Nebulon in a game adventure would require explaining how the would-be world conquerer survived his apparent death (Avengers Annual #11).
