Special Attack (Bowser)

Ads keep the MarioWiki independent and free :)
Special Attacks first appear in the game Mario & Luigi: Bowser's Inside Story. Bowser is able to use these, with each special attack using a certain amount of Special Points, or SP. Special Attacks even have a menu section in the Star Menu, where the player can watch demos and practice the attacks.
Bowser has a total of six Special Attacks that he gathers throughout the game. Like Mario & Luigi, Bowser has to unlock them in many areas of the game. To unlock these type of attacks for Bowser to use, the player must liberate Bowser's loyal, non-brainwashed troops. The player finds them in cages all around the Mushroom Kingdom. Out of the six, five of them would be found inside one of the cages. The last one is when the player collects all fifteen Blitties through the vacuum ability. Unlike Mario & Luigi's attacks, which use the buttons, Bowser's attacks use the touch screen. All six of Bowser's Special Attacks are shown in the table below (note: When using an attack with an Economy Ring, the SP cost is halved):
