In the Pop!Inktale were is not only Papyrus and Sans, but also Frisk - A piece from the memories of both skeletons, revived in the form of a girl. However, before Frisk, there was a Chara in this universe. It is already the responsibility of Only Sans, since it was recreated from his memories from the previous AU that was never completed. After meeting EDM! Underswap, Sans was inspired by the idea of making a Pop symbol of His AU is exactly Charu. He attached a lot of stereotypical pink hearts to his memories, showing that pop music is love.

Unfortunately, Chara wasn't as enthusiastic as Sans. She thought that what she was created for was stupidity. Later, Sans recreated Frisk with the help of Papyrus, without giving her such a stereotypical look this time. The charm, now because of its uselessness, was removed from the Pop!InkTale.
