Legendary hero

"Behold the Trial of Timing. You must wield Duff Shots and deflect three of my lightning attacks before time runs out. En garde!"

- Legendary hero

The legendary hero is an unseen entity in Mario Golf: Super Rush, and one of the three bosses in the Story Mode. It has electric powers. In the Wildweather Woods, the legendary hero talks to the Mii, and has them complete three trails in said area, with the third trial being a battle against the legendary hero, in the form of a suit of armor. The Mii must use Duff Shots to reflect 3 of its lightning spheres back at it, causing the trail to be complete.

The legendary hero also talks to the Mii to offer advice during the Sacred Flamebeast battle, as well as providing helpful information during their adventure. It is not fond of Wario and Waluigi, having shocked them with lightning for their greed. Although during the Sacred Flamebeast battle, it used the energy of both of them into lightning orbs to defeat the Sacred Flambeast.

It also helps the Mii against the Snow King, who has frozen Bowser's Castle.
