Bowser

Bowser is the main antagonist of Super Mario Ultra and the King of the Koopas.

Biography
During the battle, Bowser attacks Mario with spiked balls at the beginning, with fireballs for the second portion of the area, and with barrels near the end as he makes his way along. On the bridge before the switch, Bowser's attack pattern is the same as in previous battles. After the switch that collapses the bridge is pressed, however, Bowser reemerges from below. While progressing through a second obstacle course-like area, Bowser leaps across to various platforms, shooting massive white fireballs at Mario. Bowser then chases him again upon reaching a second bridge. When the switch at the end is pressed, Bowser plummets into the lava below, being hit by falling debris. After defeating Bowser, Mario gets the Huge Grand Star.

After completing all the special worlds, it is revealed that Bowser has once again stole the Huge Grand Star.
