The last Metroid is in captivity. The Galaxy is at peace...
Samus Aran logs:
"I first battled the Metroids on planet Zebes. It was there that I foiled the plans of the space pirate leader Mother Brain to use the creatures to attack galactic civilization..._"
"I next fought the Metroids on their homeworld, SR388. I completely eradicated them except for a larva, which after hatching followed me like a confused child..._"
"I personally delivered it to the Galactic Research Station on Ceres so scientists could study its energy producing qualities..._"
"The scientists' findings were astounding! They discovered that the powers of Metroid might be harnessed for the good of civilization!_"
"Satisfied that all was well, I left the station to seek a new bounty to hunt. But, I had hardly gone beyond the asteroid belt when I picked up a distress signal!_"
