The Mechanical Prototype Bub (バブルンプロトタイプ Baburun Purototaipu?, "Bubblun Prototype"), serial number Code No. CR20 - 100190 is a character that appears in Bust-A-Move 2. It is the eleventh opponent in Story Mode.
The Mechanical Prototype Bub is a large robot modeled after Bub. It has two jet boosters in place of its feet, a small tail, and a bluish-green body. It has two maroon pauldrons on either shoulder which connect to two extendable silver arms with red, ball-like hands featuring three claws on each. It has a yellow spike on top of its head mimicking Bub's spines, and a single red eye in the center of its face. Its stomach area is a gray hatch that serves as the cockpit.
The Mechanical Prototype Bub is the eleventh opponent in the Story Mode of Bust-A-Move 2, fought in Castle Drunk. As Bub enters the castle, an alarm blares, and text appears on the screen reading "WARNING!! A HUGE BATTLE SHIP CODE NO. CR20 - 100190 MECHANICAL PROTOTYPE BUBBLEN IS APPROACHING FAST." The Mechanical Prototype Bub uses a unique, metallic version of the Bubble Launcher, though it is only different in appearance, and functions the same as the player's. After the match, the Mechanical Prototype Bub crashes and explodes, revealing it to be piloted by Dreg.

- The Mechanical Prototype Bub's stage intro is a reference to the boss introductions from Taito's Darius series of games, which display text on the screen reading "WARNING! A HUGE BATTLESHIP [boss name] IS APPROACHING FAST" as an alarm blares.
