Akiko Glitter is a character in the film The Emoji Movie. She is voiced by Christina Aguilera. She was designed by Andy Bialk and has a strong resemblance to the characters he designed for the Nick TV show Shimmer and Shine.
Akiko Glitter is the host of the Just Dance app. She is one of the few characters in the Smartphone who is not an emoji.
When Gene, Jailbreak, and Hi-5 stumble upon the Just Dance app, Hi-5 turns on the game and Akiko appears. In order for them to escape, they have to follow her dance moves to move forward.
