Bombshell Bill

Bombshell Bills are the golden relatives of the Bullet Bill. Bombshell Bills are much stronger than Bullet Bills, and are positioned so as to guard extremely important areas, such as Bowser's Castle and the Palace of Shadow. However, they are instantly killed when they attack like a regular Bullet Bill even if they miss or are Superguarded. Bombshell Bills are fired by B. Bill Blasters. Bombshell Bills appear in Paper Mario and Paper Mario: The Thousand-Year Door.

Like a Bullet Bill, touching a Bombshell Bill outside battle will cause Mario to get hit by the First Strike.

Trivia

 * Unused sprites for a similar golden Bullet Bill are present in Mario & Luigi: Superstar Saga. Its Bill Blaster would have been raised compared to its normal variant and have a longer attack charge animation.
