Originally was a floating spirit called Sprout, who tried to find a body from a recently deceased person, was eventually given a body through Abby Holland having a baby, which was made through the Swamp Thing possessing John Constantine and having sex with her. Due to Constantine having the demon Nergal's blood in his veins at this time, Tefe is also part demon.
She eventually becomes the next Earth elemental, beginning a line of human earth elementals. Believing Alec Holland, the Earth Elemental known as Swamp Thing, to be dead, the collective consciousness of nature known as the Green created a new protector in the form of a young sprout.
When the Green discovered that Holland was still alive, they ordered this now-redundant Sprout executed. A reprieve came in the form of hellbound magician John Constantine. Alec inhabited his body to impregnate his human wife, Abigail Arcane Cable Holland, with the seed of this Sprout.
Cloaked in the flesh and blood of an infant child, this first human Elemental was given the name Tefe. With the ability to manipulate both vegetation and flesh on an elemental scale, she may be the most powerful creature who has ever existed.
Swamp Thing Tefe's story begins as a teenager who doesn't fit in. She realizes she doesn't fit with her peers, presumed destines, and even her own flesh. Though her parents hoped that Tefe would heal the growing rift between the plant kingdom and humanity, the Green tried to convince the girl that her actual destiny was to save their ailing planet by destroying mankind.
