While Dark Samus is only teased in the firstMetroid Prime, it turns into the final antagonist of the other twoMetroid Primetitles. It was clear that the developers loved their fair share of sci-fi films, and this can be seen during a particular moment inMetroid Prime 2: Echoes.

During their first encounter, Dark Samus points its Arm Cannon at Samus and fires a Phazon attack.
