There are fifteen types of aliens:
* '''Lander''' - the primary enemy on every level. Landers teleport into the level in staggered waves, and attempt to capture humanoids by descending upon them and dragging them into the air; if they make it to the top of the screen with a human, the two fuse together into a more dangerous Mutant. Landers can fire projectiles at the player.
* '''Mutant''' - a mutated Lander. Mutants home in on the player at constant speed, firing projectiles. They move erratically, making them difficult to shoot.
* '''Baiter''' - a flat, iridescent spacecraft that teleports in if the player is taking too long to complete a level. Homes in on the player and attempts to match their speed, while firing accurate projectiles. A difficult opponent due to its unbeatable speed and tiny horizontal cross-section, which makes it very hard to shoot.
* '''Bomber''' - a box-shaped alien that lays stationary [[Naval mine|mine]]s in the air.
* '''Pod''' - a star-like alien that bursts into a number of Swarmers when shot.
* '''Swarmer''' - a tiny teardrop-shaped alien that moves very quickly in an undulating fashion. Difficult to shoot.
* '''Firebomber''' - a rotating variation on the Bomber, which shoots high speed '''Fireballs''' at the player.
* '''Yllabian Space Guppie''' - an undulating attacker, which attacks in swarms and homes in on the ship.
* '''Phreds''' and '''Big Reds''' - square aliens which look like they are constantly opening and closing their mouths. Similar to the Firebombers, they launch tiny versions of themselves called '''Munchies'''.
* '''Dynamos''' - diamond-shaped ships composed of clusters of '''Space Hums''', which periodically break off to attack the ship independently. Once all aliens (except Fireballs, Space Hums, Baiters, Phreds, Big Reds, and Munchies) are destroyed, the player progresses to the next level.
