From the Super Mario Wiki
Rage is one of the Vibes that Princess Peach could use during the events of Super Princess Peach. It is used by touching the red Heart Panel. Fire would appear all over the princess, and destroy anything that she touches. It would also light up dark areas. However, Peach would not be able to jump very high but when touches back to the ground she will stomp. Also, the music gets 4 times slower when Princess Peach uses this vibe.
Along with Princess Peach, several enemies throughout the game, such as the Army Hammer Bro, can utilize the Rage vibe.
