Billy's falling out with id Software left a scar of resentment. When id produced Doom II, the sequel to their ground-breaking 3d game Doom, it included a secret level in which the player must kill Commander Keen to finish the level.
August, 1994. With the toystores full of Commander Keen merchandise and kids across America leaping around on Pogo sticks, Billy's fame and celebrity status seemed under no immediate threat despite the drop in popularity of the old Commander Keen computer games.
Believing that he could "make it on his own", Billy Blaze, with the support of his parents and a fleet of lawyers, set about organising a Saturday morning television cartoon show: The Heroic Adventures of Commander Keen.
But the media is a difficult thing to work with, and soon it would turn against Billy, as disaster befell with the strength of a Quantum Explosion Dynamo.
Suddenly, a freak accident involving a pogo stick caused Commander Keen merchandise to be banned in a number of states.
With newly-emerging computer games of higher quality than that of Goodbye, Galaxy, Billy Blaze's celebrity status was fading rapidly.
As the year 1995 progressed, Billy, abandoned by id Software and forgotten by most people as if he was just a passing fad, tumbled down the slippery slope of post-stardom.
And when he finally hit post-stardom's tar-slicked bottom of unpopularity, he began to sink further, into a world of alcohol binges and petty theft.
The downfall of Commander Keen had begun in earnest.
