Killer Ball

Killer Ball is the Star Skill used by Bowser in Mario Superstar Baseball and his Star Pitch in Mario Super Sluggers.

When Bowser uses the move, the baseball turns into a Bullet Bill. If Killer Ball is used while pitching, the Bullet Bill slowly moves toward the home plate, does a loop, then zooms by the batter. If Killer Ball is used while batting, the Bullet Bill dashes across the field. If a fielder catches the ball, they are pushed a distance back.

In Mario Superstar Baseball

In Challenge mode, Bowser can only start using Killer Ball once the Bullet Bill item has been purchased. His son, Bowser Jr., has a Star Skill that is a variation of the Killer Ball, named the Killer Jr. Ball. It is the same as the Killer Ball except Bowser Jr.'s Bullet Bill is shown wearing his bib.
