Fake tank

The Fake Missile Expansion is, like its name reveals, a fake Missile Expansion. Samus encounters this thing in Sector 5 aboard the Biologic Space Laboratories research station in Metroid Fusion.

When Samus first enters the room, the creature looks like a normal Missile Expansion. However, once she gets close to it, eyes and bat-like wings appear from the item. Once Samus fires a Missile at the thing, it will transform into an X Parasite. If she bombs the wall in front of her, she will obtain a real Missile Expansion.
