Bubble Bobble Wiki

Bub, known as Bubblun (バブルン Baburun?) in Japan, is the protagonist of the Bubble Bobble series. He is a Bubble Dragon, and the twin brother of Bob. Bub made his debut in the first Bubble Bobble game, and has appeared in nearly every game in the series since. His human form is named Bubby. He lives in Rainbow Village on Rainbow Island with his parents and brother.



Bub is a green Bubble Dragon with yellow spines. He has reddish-pink arms and feet, as well as a white stomach area. Like most Bubble Dragons, Bub has a single visible tooth in the upper middle part of his mouth.

In some titles in the series, Bub is shown wearing goggles and a satchel, a trend that started in the mobile title New Bust-A-Move.


Bub is generally portrayed as being rowdy and cheerful, always looking for adventure, as well as being very optimistic. He shares a close relationship with his brother, Bob, and the two have gone on many adventures together. Bub's catchphrase is "Payonpah!" (「ぱよんぱー!」 Payonpā?), a nonsense word that he often exclaims happily. This phrase first appeared in the Bust-A-Move series, but later made its way over to the main series of games.

Bub's favorite food is fruit, while his least favorite food is umeboshi. He once ate one, mistaking it for a cherry, but did not like the sour taste. His hobby is exploring new and unknown places, and dreams of becoming an adventurer.


Bub's trademark ability involves producing and firing bubbles from his mouth. If the bubbles make contact with an opponent, they get trapped inside, allowing Bub to pop the bubble with his spines in order to defeat them. Along with utilizing the bubbles to attack foes, Bub is also able to jump on them in order to reach new heights.

In several games in the Bubble Bobble series which feature playable characters with different stats, namely Bubble Symphony and Bubble Bobble Revolution, Bub is usually the most rounded character, bearing average jump height, speed, bubble fire rate, and range.

In addition to his normal bubbles, several games have allowed Bub to charge up his bubbles, the effect of which varies from game to game. The first game to feature this ability was Bubble Bobble Part 2, in the form of the Super Bubble (スーパーバブル Sūpā Baburu?) technique, which allows Bub to fire multiple bubbles at once. Additionally, if the player continues to hold down the button and continues to charge, Bub will inflate like a balloon, allowing him to slowly float upwards, allowing him to access previously unreachable areas. The Super Bubble returns in Bubble Bobble Junior along with the floating ability, however, Bub encases himself in a bubble instead, similar to the stage transitions in the original Bubble Bobble.

A similar mechanic is implemented in Bubble Symphony, with each of the four playable characters having a different formation of bubbles that they can fire. Bub is able to shoot three bubbles straight forward, trapping any enemies directly in front of him. Unlike Bubble Bobble Part 2, the ability to float is not present in the game.

Bub retains the ability to charge his bubbles in Bubble Memories, albeit with a new twist. By charging up his bubbles, Bub can unleash a Giant Bubble (巨大バブル Kyodai Baburu?) which can trap multiple enemies at once. This ability returns in Bubble Bobble Revolution in the form of the Charge Bubble (チャージバブル Chāji Baburu?), which in addition to trapping multiple enemies, can bounce off of walls. After bouncing off of a wall, if the Charge Bubble collides with Bub, he will enter it and perform the Rolling Bubble (ローリングバブル Rōringu Baburu?) technique, which allows him to charge into enemies and defeat them. In Bubble Bobble Double Shot, Bub gains the ability to blow Thunder Bubbles after obtaining a Crystal Ball.

Bub is also stated to possess magical abilities due to his parents being magic users; this is shown via his human form in the Rainbow Islands series being able to utilize Rainbow Magic.

Aside from his abilities as a Bubble Dragon, Bub is also skilled in sports, particularly those using a ball.


Bubble Bobble[]

Bub first appears in Bubble Bobble as the first player character. Bub, along with his brother, Bob, were turned into Bubble Dragons by Super Drunk after attempting to rescue their girlfriends, Betty and Patty, who were kidnapped after wandering into the Wizard's Forest. The duo sets out to travel through the 100 levels of the Cave of Monsters and defeat the girls' captor.

Upon reaching the bottom of the cave and defeating Super Drunk, Bub and Bob manage to rescue their girlfriends, as well as their parents, who were under the control of an unknown figure who had been giving orders to Super Drunk.

Rainbow Islands[]

Bub appears in human form as Bubby, who acts as the main character of Rainbow Islands. Bubby is shown being transformed into Bub by the Boss of Shadow's magic and thrust into a cage along with the transformed villagers of the Rainbow Islands if the player gets a Game Over while fighting the game's final boss.

Bubble Bobble Part 2[]

After his adventures in human form during both Rainbow Islands and Parasol Stars, Bub returns to his Bubble Dragon form in Bubble Bobble Part 2 to rescue his friend Judy, who has been kidnapped by the Skull Brothers. Bub and Bob set out to defeat the evildoers and rescue Judy, traveling to their lair and defeating the various monsters that await them along the way. After defeating the Skull Brothers, a Fairy returns Bub to his human form, and he and Judy reconcile.

In the original Japanese story (which was also used on the back of the game's box in North America), the characters in Bubble Bobble Part 2 are actually named Cubby (カビー Kabī?) and Rubby (ルビー Rubī?), and are the descendants of Bub and Bob. This is ignored in the North American manual, and most supplementary material for the game presents the two as simply being the same Bub and Bob as the original Bubble Bobble, though the back of the box still refers to the two characters as Cubby and Rubby. Judy was also Cubby's girlfriend in the original story, but she is mentioned to just be a friend of the duo in the American version.

Bubble Bobble Junior[]

After being away from his village in order to train, Bub returns one day to find his home in crisis. The inhabitants of the village have been abducted by the newly revived demon king, Great Skel, who has unleashed his army of monsters upon the land. Upon seeing this, Bub sets out to rescue the villagers and defeat the demon king.

Much like Bubble Bobble Part 2, the main character in the original Japanese story was known as Robby (ロビー Robī?), also known by the nickname Bubblun Jr. (ばぶるんJr.ジュニア Baburun Junia?).

Bubble Symphony[]

Bub appears once again in Bubble Symphony, joined by Bob and new playable characters Peb and Pab (referred to by their Japanese names, Kululun and Cororon in-game). The game begins with the four reading a book, when Hyper Drunk emerges from within, transforming the four into Bubble Dragons and banishing them to the Storybook World. The four must find the four keys hidden throughout the Storybook World, and defeat Hyper Drunk to return home. If Bub collects three bubbles, each with the letters 'R', 'O', and 'D' on them, he can transform into Bubby, attacking instead by blowing bubbles through a bubble pipe. After defeating Hyper Drunk, the four become the kings and queens of the Storybook World, and return back home.

Bubble Symphony's intro states that the four characters in the game are the children of Bub and Bob from the original Bubble Bobble, but several sources contradict this, namely the game's promotional flyer, as well as later games featuring Cororon and Kululun that simply refer to them as Bub and Bob's girlfriends.


Bub is the main playable character in Bust-A-Move. In this game, he must shoot bubbles out of a Bubble Launcher in order to pop the bubbles of a matching color at the top of the stage.

After reaching Castle Drunk and defeating Drunk and his mech, the Mechanical Prototype Bubblen, Bub returns the stars back into the sky where they belong. Bub is also the playable character in the game's Puzzle Mode, but a different character can be selected in the console version if the player inputs a code.

In Bubble Memories, Bub and Bob act as the only two playable characters once again. The two now have the ability charge up their bubbles to create a giant bubble in order to capture multiple enemies at once.

  • Bub's status as a human transformed into a Bubble Dragon has been portrayed inconsistently across the Bubble Bobble series. In most of the mainline games of the series, Bub is usually shown transforming back into a human at the end of the game, but in most spin-off titles, he is implied to be stuck as a Bubble Dragon, or his status as a human is completely ignored. In Bubble Bobble Double Shot, both Bub and Bob's cousin Bubu and their Grandfather are shown as Bubble Dragons, and no reference is made to the brothers being human at all.
  • Despite being stuck as a Bubble Dragon, Bub does not mind the transformation because people say he is cute.
  • Bub's birthday is on August 28.
