Red-eyed Watcher



"Red-eyed Watcher" is a conjectural name for a mysterious, unseen creature in Metroid: Samus Returns. The creature's body is not seen, apart from its menacing, glowing red eyes. It is located in Area 4. Its eyes periodically appear seemingly out of nowhere in the background and blink once, before breathing heavily through its nostrils. It then disappears. This creature is the only background specimen in Samus Returns that does not have an internal filename, suggesting that it may be a particle effect or something similar. None of these creatures existed in the original Metroid II: Return of Samus, which featured minimal backgrounds.
