The Alien Intruder is the main antagonist of the Popcap Game, Feeding Frenzy 2: Shipwreck Showdown, the sequel to the original game, Feeding Frenzy. It was first encountered by Boris the Butterfly Fish and then later became a threat of Shady Shoals, destroying undersea labs in Sharktooth Ridge and as well as causing shipwrecks, changing the color of the fish, making them toxic and sick, and causing the marine life to go havoc, making them move far from their habitats. It was later fought by Goliath the Great White Shark, and defeated it by shrinking down to a small size. Then comes the sequence of the fish heroes to shrink and defeat the Alien Intruder until it has come up with a plan to release millions of microspores all over the world's oceans, becoming a world-wide threat. Eventually, it was defeated by Boris after he shrunk it down to a size small enough for him to eat.

The Alien Intruder later becomes a playable character, letting the player play through the entire game's story as the Alien Intruder.
