Talk:Bowser Jr. VS Metal Sonic/@comment-32765736-20180314013620/@comment-32765736-20180323060533

The Grand Star range from Galaxy to Universe. The Grand Stars are more powerful than the Power Stars which the Lumas are capable of turning into and Lumas are capable of turning into Galaxies. The Grand Star also is possibly Universal due to having the power to collapse a universe and recreate new ones. Bowser Junior's Megahammer is powered by this.

So in short.....

Bowser Junior stomps ;-)
