MEGASTAR

(literally my first time making a wiki page i am so sorry if this is bad)
MEGASTAR is a version of Mario who was addicted to superstar powerups. He liked the rush of energy the powerups gave him, so he'd continue to consume and collect them any time he could.
This leads us into the events of Super Mario Galaxy. Mario has just defeated Bowser and obtained the Grand Star. He's addicted, so (stupidly) he consumes the Grand Star as if it were a powerup. This gives him way more power than a normal superstar, but all that power unfortunately goes to his head and, upon his return to the Mushroom Kingdom, goes on a rampage, killing dozens of Toads, and even the princess. However, his brother was one of the very few survivors. But now, Mario's on the hunt for them.
