Bubble Bobble Wiki

Develon (デビルン Debirun?, "Devilun") is an antagonist in the Bubble Bobble series, and a recurring playable character in the Bust-A-Move games. He is Bub's self-appointed rival, and regularly attempts to sabotage his efforts whenever the two meet.



Develon is a black Bubble Dragon with red spines and wings. He has purple limbs, and has sharper claws than most other Bubble Dragons. Due to his appearance, he is believed by many to be a demon.


Develon is extremely competitive and hates to lose, often picking fights with Bub. He aspirations of becoming ruler of the universe, as shown by his ending in Bust-A-Move 4 and role in Space Bust-A-Move, but does not seem to be regarded as truly villainous, as Bub has been shown to be friendly towards him on several occasions. Despite his strong-willed personality, Develon is stated to be nothing more than a lonely coward.

Develon's catchphrase is "Payongah!" (「ぱよんがー!」 Payongā?), a nonsense word he exclaims in excitement, mirroring Bub's own catchphrase.


Develon's trademark method of attacking is by breathing fire, an ability that most Bubble Dragons lack without the use of a Cross of Fire or a Special Bubble. Unlike most Bubble Dragons in the series, he has not been shown to be able to spit bubbles, but whether or not he lacks the ability or simply has not been shown using it is unknown. Develon is one of the few Bubble Dragons with wings, which he can use to fly. He is also able to transform into a bat.
