Alien

Alien (エイリアン) is the final boss from Mega Man 2. When the player enters his room, Dr. Wily will jump from his flying saucer and turn into a green alien. Its only weakness is Bubble Lead, and all other weapons refill all its energy when used against it. The Alien shoots and flies slowly throughout the room, always in a figure eight pattern. When it's defeated, it is revealed that it was just a hologram created by Dr. Wily, and the alien was a small flying ball.

Trivia

 * The reason the Alien is only weak to Bubble Lead is that it is only a hologram - the bubbles do not actually harm the Alien itself, but instead cause the projector to short-circuit.


 * "Dr. Wily's Secret", the subtitle to Mega Man 2, refers to the scene in the game where Dr. Wily turns into the Alien.


 * In Mega Man Network Transmission, the Life Viru's embryo-like second form acts almost exactly like the Alien.
