Esme lost her parents and had been in a foster system until 2021. After her abusive caretaker was arrested, a family tried to take her in, but due to the chaos of the Humanity Totem, Esme didn't fit in there. A sympathetic Alex and Kelly decided to adopt her. Esme found her new family more unique and accepting than she expected; having not only Alex and Kelly, but Kara as an aunt and J'onn as a surrogate grandpa, along with Lena, William, Brainy and Nia.
Esme became the host of the Love Totem due to strong love her mothers had. This made her the target of Nyxly and Lex, who needed the totem out of her.
