Mega Man 4, known in Japan as Rockman 4: A New Evil Ambition!, is the fourth game in the Mega Man series released for the Famicom and NES late in the console's life (1991-93). The game introduced the Mega Buster as well as the concept of a "fake" villain (in this case- Dr. Cossack).

Overview
Many thought Dr. Wily was dead after he was crushed in the last game. When they thought their troubles were over, a scientist named Dr. Cossack claimed that Mega Man and Dr. Light were creating better robots than he, and wanted to put them out of business. He sends 8 robots to destroy Mega Man.

Later, Mega Man realizes Dr. Wily is still alive, and has held Dr. Cossack's daughter Kalinka hostage. Dr. Cossack was forced to destroy Mega Man. Proto Man frees Kalinka, and Mega Man enters Dr. Wily's castle to defeat Dr. Wily (for the fourth time).

As a side note, Mega Man's item-giving friend, Eddie, makes his debut.

Story
A year after the destruction of Gamma, a mysterious message arrives at Dr. Light's Lab...

Good Evening, Dr. Light: ''Allow me to introduce myself - I am Dr. Cossack. You may not have heard of me, but soon the world will know my name.''

''Over the years, you have been hailed as the greatest robot designer in the world, while my robotic creations have been totally ignored. I cannot allow this to continue. The world must be made aware of my genius!''

''From my Siberian citadel, I've sent eight of my most powerful robots to destroy the titanium troublemaker, Mega Man. Once they have obliterated him, I will place his broken body on display for the entire world to see. Only then will I be allowed to take my place as the greatest robot designer of all time!''

Dr. Cossack

Actual Story
A year after the Gamma Incident (2010), the world had been living in peace and thought that Wily was gone for good. However, Dr. Light received a letter from a mysterious Russian scientist named Dr. Cossack, claiming to be the greatest scientific genius in the world and having been far too long overlooked, challenging Light and Mega Man to a "contest" of sorts. Cossack's new army of Robot Masters began to make their move, so Mega Man, with his newly equipped Mega Buster went after Cossack. In the end, it turned out that Cossack's daughter Kalinka had been kidnapped by Wily (who was very much alive and, it appears, hiding in Russia), but luckily Proto Man "betrays" Wily and rescues her. Mega Man heads to Wily's citadel and defeats him once more.

Trivia

 * The opening scene of the game shows Mega Man with blue hair, while the ending scene shows him with black hair.


 * It should be noted that this is the first Mega Man game with the Wily Capsule (teleporting saucer) as the final Wily boss, which will torment Mega Man for the rest of the classic series.


 * Coincidentally, the Wily Machine in this game is also the first of many to have the skull motif, a trend that is followed by all succeeding games' Wily machines.


 * This is also the first game to feature a unique music track for the game's last boss.


 * Of all the classic Mega Man games, Mega Man 4 takes the longest time to fill the health meters for Mega Man and his enemies.


 * This is the first time Mega Man can charge his buster due to the addition of the New Mega Buster.


 * This is the first game where Dr. Wily tried disguising his intentions by making it seem as if someone else is behind everything.


 * This game's second song for the Wily stages bears a heavy resemblance to the Wily theme from Mega Man 5.
 * This is the only game in the series to feature two water-themed Robot Masters: Dive Man and Toad Man.


 * It is possible for Mega Man to "kill" Dr. Wily after Wily escapes from his Wily Machine No. 4 in his escape pod by using the Rain Flush as seen in the video below. However, doing this will result in Rock getting stuck in Wily's chamber and the player having to reset the game.
