Nickelodeon All-Star Brawl 2 was the first Nickelodeon product where Korra from The Legend of Korra isn't voiced as an adult by Janet Varney, instead being voiced by Jacqueline Grace Lopez, while Nickelodeon Kart Racers 3: Slime Speedway was the last time Varney portrayed the character. The reason for this is that in 2022, a year before All-Star Brawl 2 was released and the same year as Kart Racers 3, Varney announced that she was stepping down from the role because she wanted Korra to be voiced by a person of color, much as Korra herself is, following the announcement of a new Avatar: The Last Airbender movie starring Korra to be released in 2025.
