One of the many Disney Cast Members portraying Vanzell Mar-Klar at Disney's Hollywood Studios
Mar-Klar was the main character of the now defunct Disney Parks attraction Jedi Training: Trials of the Temple, found at multiple Disney theme parks. The character and his students were played by a variety of Disney Parks Cast Members of different ages and genders, with younglings portrayed by park guests. The boots worn by the Cast Members portraying the Jedi Master match those worn by Jedi Master Kelleran Beq, the host of the Star Wars: Jedi Temple Challenge game show.
