Invisibility, or Cloak is a power-up in the multiplayer modes of Metroid Prime 2: Echoes and Metroid Prime Hunters. When collected, it renders the user nearly undetectable for a short period of time. In Echoes, players are completely invisible, while in Hunters they are only highly transparent. When players view themselves (either by seeing their arms in first-person, or their Alt-Form in third-person) they will see themselves as mostly transparent (with a blue tint in Echoes). While cloaked players are visible on the radar in Hunters, they are not displayed in Echoes. In Echoes, the effect can be countered by using the Dark Visor.
- Certain enemies in the Metroid series, such as Reptilicus, Dark Samus and Gorea, are able to cloak themselves as a combat tactic.
- Trace is able to cloak himself when using the Imperialist, but only if he is stationary.
- Sylux is erroneously said in the Metroid Prime Hunters Official Nintendo Player's Guide to have this trait.
- Samus Aran's Gunship is implied in a Space Pirate scan in Metroid Prime to have a cloaking device, as they were unable to locate it. The ship is depicted as having a camoflauge device in Metroid: Zebes Invasion Order.
