Story
From the game box:

"Break the death-grip of the ultimate computer! As Mega Man, the robot wunderkind created to save the world, match your mettle against the mind of Dr. Wily, a megalomaniac with the hardware to match his ego! Search Wily's mechano-botic complex, from it's mind-bending maze of electrified corridors, through giant whirling turbines and into paralyzing force fields. You must find the three keys into the core room! Leap pools of supercharged gunk. Pulverize ion-sucking Batimms and other insidious insectobots. Face a phalanx of slithering, seething cyborgs, all programmed to turn you into radioactive waste! At last, confront Crorq, a megacomputer revived by the psychotic calculations of Wily's mad brain. Survive and challenge the mastermind behind the superbrain, Dr. Wily himself!"

Trivia

 * Unlike other games, Mega Man only features three Robot Masters, unless one counts Buster Rod. G, Mega Water. S, and Hyper Storm. H from Mega Man: The Wily Wars's Wily Tower mode.
 * The game features no music, and uses inferior graphics and sounds compared to their NES counterparts.
 * Because the box art uses an unedited section of Mega Man 3's box art, Rush is featured in the background and Spark Man in the back of the box, but they are not in the game itself.
 * When Mega Man uses a Robot Master's weapon, he does not change color.
 * As with many other Mega Man games from when the series first began, Dr. Wily's name it misspelled.
