Avatars were added in Beta 18.1 to promote Undercards' new UCP Currency, as these are only able to be bought with UCP.
Avatars are just for show, able to be seen next to your name anywhere: In the Home Menu, on your profile page, your profile page in the chat and in battle. Various items and characters from Undertale are shown on these, most of which look slightly or completely different from their card counterpart. Some also just have their head shown, like the face images main characters have in their dialogue box in Undertale.
There are quite a few similarities between Avatars and Cards:
- There are the 5 Rarities of Common, Rare, Epic, Legend and Determination.
- Note: There were no Determination Avatars on release.
- Each Avatar of the same Rarity costs the same amount of UCP.
- The higher the Rarity, the more UCP they cost to get.
- Common: 0 UCP
- Rare: 100 UCP
- Epic: 200 UCP
- Legend: 300 UCP
- Determination: 500 UCP
- The original Common, Rare and Epic Avatars were colourless.
