Samus Aran was sent to the lab on planet SR388 to find out what happened to the biological research team (BSL) after losing contact with them over a period of time. Upon arrival, the first thing he saw was a desolate space, and everyone seemed to have gone missing. He was about to search for clues, but suddenly a Hornoad appeared and tried to kill him with a weapon. Failed, Samus promptly reacted and destroyed him. Soon after, an amorphous creature called X Parasite invaded Samus’s body. His nervous system has been compromised, which results in loss of memory as well as loss control of many body organs. Luckily, he was able to endure. He returned home, had surgery and an immunization vaccine. The mystery going on at SR388 has not been revealed yet, where does the appearance of X Parasite come from? What is the purpose of the person behind this plot?
