Avatars were first introduced in Just Dance as random icons, and they returned in Just Dance 4 as mono-color circles. They made a colored and shaped re-appearance in Just Dance 2014 and a colored sticker appearance in Just Dance 2015, Just Dance 2016, Just Dance 2017, Just Dance 2018, Just Dance 2019, Just Dance 2020, and Just Dance 2021.
The avatars in Just Dance did not represent any song and were instead unrelated pictures.
The avatars on Just Dance 2014, Just Dance 2015, and Just Dance 2016 have a wider selection and are in color. One can select an avatar that represents his/her favorite routines.
The avatars in Just Dance 2014 can also express emotions when pressing some buttons. They can smile, wink, blow a kiss, growl, laugh, stick out the tongue, and blow a bubble using bubblegum. Avatars can be unlocked by playing their respective songs, month-unlocked Mashups and the World Dance Floor.
The avatars in Just Dance 2015 can do the same things. In the World Dance Floor however, they are unable to perform those actions, but are instead able to verbally express themselves depending on which button you press. Expressions range from "Lol!" to "Oh no!". They can also say things without you pressing any buttons, such as "Grrr" when you are overtaken by an opponent. They share similar ways of unlocking avatars with Just Dance 2014, but now gives only one avatar per song. Alternate routines also have their own avatars.
In Just Dance 2016, the avatars are the same as the ones in Just Dance 2015. However, the avatars no longer blink nor express emotions (except on 7th-generation consoles).
In Just Dance 2017, the avatars are similar to Just Dance 2015 and Just Dance 2016. Similar to Just Dance 2016, they can be unlocked after playing a song. Now they can make sounds and do some actions like spinning, zooming in quickly, and shake.
The avatars in Just Dance 2018 similar to its predecessor Just Dance 2017, do the same actions and sound effects, however, now they have to be unlocked via the Gift Machine.
The avatars in Just Dance 2020 can be unlocked in two ways, either by the gift machine, which gives you the Just Dance 2020 kids mode avatars or avatars from previous games or by dancing to any song in Just Dance 2020. A gold version of the avatar can be unlocked by getting a Megastar or higher on that song.
