First appearance


Jenny Quantum was born January 1, 2000 in Singapore, during the death of Jenny Sparks, where her birth mother was killed by super villains attempting to kidnap her and shape the coming century. Her biological father’s identity and whereabouts are unknown. She was rescued and cared for by the Authority and later adopted by Apollo and Midnighter shortly after their marriage. She is the current leader of superhero team, The Authority.

Jenny first appeared in The Authority #13 as a child and Authority: Revolution #7 as a teenager, although it could be inferred that Quantum is the newborn depicted in the last panel of The Authority #12 . Quantum is the corporeal spirit of the 21st century, and the youngest known Century Baby, as well as the reincarnation of the Spirit of the 20th Century, Jenny Sparks.

Quantum forced herself to age several years into her teens so that she could better fight the threat of Henry Bendix and his evil group. While fighting Bendix, Jenny was able to free the current Doctor, Habib Ben Hassan, and enlist him in the fight against Bendix.

It has been stated that Jenny Quantum's powers are far in excess of those possessed by her predecessor Jenny Sparks,("make her previous incarnation look like a spastic with a guide dog") and that she still is the most endangered of all.

Interdimensional Teleportation: She has the ability to teleport between points on Earth and also other dimensions


Dimensional Manipulation: Inspired by the Doctor's Garden of Ancestral Memory, Jenny created a dimension for all her ancestors called the Infinite City, a metropolis of assorted time-periods on the back of a giant turtle.

Appearances, Images, and QuotesEdit


  • Jenny Quantum's lineage extends to the earliest accounts of human history, which include Jenny Stone and Jenny Fire, the first two "Century Spirits". Her direct ancestors before Jenny Sparks are Jenny Steam, Jenny Revolution, Jenny Plague and Jenny Inquisition.
  • It has been suggested that, like Jenny Sparks, Jenny Quantum and the human race are linked for the current century and in Jenny Quantum's case, until the end of 2099. Meaning during a great depression, Jenny would be in a state of personal depression, though it is unknown if one causes the other or how. It has also been theorized that if she were raised with, for example, Nazi beliefs then humanity would fall under similar philosophies, though this has yet to be determined.
