Bubble Bobble Wiki

Invader (いんべーだ Inbēda?), also known as Super Socket, is a recurring enemy in the Bubble Bobble series. Invaders are based off of the titular enemies from Taito's arcade title Space Invaders, and have made an appearance in most main series Bubble Bobble games.



Invaders are mechanical creatures with two blue antennae, and are generally shown with bodies vaguely shaped like a pentagon. Their arms and legs move in a motion reminiscent of the enemy sprites from Space Invaders, and have mechanical joints. Their bodies are colored silver, and in most appearances, the bottom half of their bodies are purple in color. In Bubble Bobble Plus!, Invaders take on a more blocky appearance reminiscent of a 3D model of their original sprite from Bubble Bobble.


Invaders' main form of attack is firing a laser downwards. The laser can travel through platforms, and will cause the player to lose a life if they make contact with it. Unlike most enemies, Invaders are only able to move left and right, and cannot jump in any way, though they move faster than most other enemies.


Bubble Bobble[]

Invaders first appear in Bubble Bobble, and are first encountered on Round 60. They move back and forth rapidly, firing lasers down at the player to attack. Invaders are the only enemy not encountered in the game's Super Mode, and are replaced by Hidegons in said mode.

Rainbow Islands[]

Invaders appear as an enemy in Rainbow Islands, and are only encountered on the game's final world, Bubble Island. They behave similarly to their appearance in Bubble Bobble, but are in a perpetually angered state, like the other enemies encountered in the world.

Parasol Stars[]

Invader returns as an enemy in Parasol Stars, appearing in the game's penultimate world, Bubble Star, a world based off of the original Bubble Bobble. The Invaders in this game have a slightly different appearance than most of their other incarnations, having a much wider body, differently shaped antennae, and having red orbs at the end of their arms, resembling the enemy sprites from the original Space Invaders. Despite this, they behave nearly identically to their original appearance in Bubble Bobble.

Bubble Bobble Part 2[]

Invaders appear as enemies in Bubble Bobble Part 2, having the same behavior as their previous appearances. In this game, they are completely yellow and lack antennae.

Bubble Bobble Junior[]

Invaders appear as an enemy in Bubble Bobble Junior, returning to their original design. A new related enemy known as an Invader Crate is introduced, resembling a large UFO. Invader Crates constantly spit out Invaders to attack the player, only stopping upon being defeated by being hit with bubbles multiple times, or being hit with a Special Bubble.

Bubble Symphony[]

Invaders appear as enemies once again in Bubble Symphony, behaving much like their previous incarnations. A Giant Invader appears as the boss of the TV Machine and Central Park worlds in a boss battle that serves as an homage to Space Invaders, summoning rows of Invaders in a manner reminiscent of the original arcade title's gameplay. Two new varieties of Invaders based off of the different enemy types in Space Invaders appear during this boss fight, one resembling the Invader design used in Parasol Stars, having flat antennae and a more box-shaped body, and another with closed eyes that lacks arms and antennae.
