An history of title confusion in the Metroid series.

1980s-1990s : no, no, the main character is not called Metroid, the lifesucking reptilian jellyfish are the metroids

2000s : OK, the lifesucking jellyfish are supposed to be extinct now, but she's got some DNA of them, so technically, you know, she's kind of a metroid...?

2020s : Metroid lady's gonna eat your face.
