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 and its Chinese version, Just Dance 2016, Just Dance 2017 and its Chinese version, Just Dance 2018, Just Dance 2019, Just Dance 2020 and its Chinese version, Just Dance 2021, and Just Dance 2022.
The avatars in Just Dance did not represent any song and were instead unrelated pictures.
Starting from Just Dance 4, avatars have a 2D white and transparent appearance. They represent coaches from the game itself or from past games. They can be unlocked through the Wheel of Gifts.
Starting from Just Dance 2014, avatars are in color and have a much wider selection. Most avatars for Just Dance 2014 coaches can be unlocked by playing their respective routine, whereas most other avatars are either purchasable through the Avatar Shop or unlockable through different means (such as achieving a certain level on World Dance Floor or unlocking a monthly Mashup).
From this game onwards, specific animations are triggered when pressing some buttons: they can smile, wink, blow a kiss, growl, laugh, stick out the tongue, or blow a bubble using bubblegum.
Starting from Just Dance Wii U, avatars are more detailed.
In Just Dance Now, avatars are also unlocked by playing their respective map; however, each of them only has one avatar (even though some multiplayer maps might have additional avatars that are available for purchase in the Shop).
From the major update made on October 22, 2015 to the other update made in June 2017, each main avatar also had golden and diamond counterparts, which could be respectively unlocked by reaching Level 3 and 6 in their respective maps.
Starting from Just Dance 2015, avatars have a sticker-like appearance. Coaches for Alternate Routines can also have their own avatar. Like in the previous title, avatars have animations, even though they cannot be triggered while playing World Dance Floor; however, written messages (such as "Lol!" or "Oh no!") can pop up depending on which button one presses. Some of these messages can also be caused by certain events: for example, when an opponent beats the player, they say "Grrr". These mechanics return in the 7th-generation version of every following game, up to Just Dance 2020.
In 舞力全开2015, it is similar to Just Dance 2015. However, selected avatars from the previous games will be unlock based on Game Level (instead of Online Level, since there is no World Dance Floor existing to unlock the avatar) to be followed by current avatars of the song's choice.
From Just Dance 2016, avatars no longer blink nor express emotions (except on 7th-generation consoles). On 8th-generation consoles, many avatars can be unlocked by playing their respective map via Just Dance Unlimited.
In Just Dance 2017 and 舞力全开2017, each avatars has its own sound effects. They can also perform some actions when pressing certain buttons, such as spinning, zooming in quickly, and shake (except on 7th-generation consoles).
In Just Dance 2019, in a similar way to its predecessor, avatars can be unlocked by paying 100 Mojos to start the Gift Machine up (excluding those that have to be purchased by registering in Ubisoft Club).
The avatars in Just Dance 2020 can be unlocked in two ways: either by playing any map in Just Dance 2020 or through the Gift Machine, which gives Just Dance 2020 Kids Mode avatars or avatars from previous games. A golden version of every Just Dance 2020 avatar can be unlocked by earning Megastar or higher on its related map.
In 舞力全开, avatars are also similar to Just Dance 2020, but avatars from World Dance Floor, Ubisoft games and All Stars Mode are removed since they are not in the game. More avatars are added through 舞力无限 seasons, including a 1 year anniversary avatar, avatars of 舞力全开 (Wu Li Quan Kai) (Alternate) and avatars of Just Dance 2021, they are unlockable by dancing to the respective maps on 舞力无限.
The same mechanics are applied to Just Dance 2021; however, avatars from previous games are no longer available, and avatars based on coaches from non-solo routines are unlocked via the Gift Machine.
The same mechanics are applied to Just Dance 2022; however, unlike previous games, playing songs on the World Dance Floor counts towards unlocking avatars. Additionally, Kids Mode avatars from previous games are unlocked from the start instead of needing to be unlocked via the Gift Machine.
