Trivia

 * Had this been completed and released, this would have been Mario Obsessed's:
 * First MO fan game based on Mega Man.
 * The first crossover fan game by MO.
 * Had Kirby's Crossover RPG' and Kirby's Fruit Fury' not been released prior it would have been:
 * The first appearance of Miyuki Takara (from Lucky Star) in an MO game.
 * Otherwise:
 * This would have been the third MO fan game released.
 * The project was cancelled due to MO's dislike towards it's current state. When development was discontinued, Mega Man OP was very early in development.
 * The graphics aren't 8-bit styled, unlike Mega Man OP.
 * Despite this, the screen resolution is still 256x224.
 * The game was going to have started a series, and it's sequel was in development. It would have featured Zero as a playable character (the first instance of two playable characters in a MO fan game) and Lex Luthur from Superman would have been the villain. It was cancelled.
