age her control and power increased. By 1919 Jenny stopped aging. In various comics, a number of Sparks' adventures through the early and middle part of the 20th century have been told. A common theme in these stories is her interaction with prominent historical figures. In the 1960s through 1980s Sparks is shown to have become involved with the first British bands of superheroes, but she encounters problems with some extreme personalities that disillusioned her to that role. Stormwatch and The Authority Despite those experiences, in the 1990s she agrees to join a new group called Stormwatch that has been formed by a man named Henry Bendix Against her wishes she is given command of a covert team called Stormwatch Black. When Stormwatch disbanded after the Xenomorph attack that took the lives of half the team, she created a new superhero group called The Authority alongside a number of Stormwatch Black teammates. During her leadership, Jenny and her team faced many threats, including super-powered terrorists and an invasion by an alternate reality. On 31 December 1999, Jenny Sparks knew that she would die at midnight as the 20th century ended (this date is erroneous due to the common mistake that the 21st century began on January 1, 2000 and not its actual date, January 1, 2001), a fact known only by her teammate The Doctor. She electrocuted the brain of an enormous alien creature, the "God" that had originally created Earth and which was planning to wipe the planet clean of all life. This was her final act, in her words, as humanity's defense mechanism. She died moments later in her teammates' arms. Her dying words and last will were: "Save the world. They deserve it. Be better. Or I'll come back and kick your heads in." The passing of the spirit of the 20th century heralded the arrival of a successor. At the moment Jenny Sparks died, a new entity was born: Jenny Quantum, spirit of the 21st century. During the Transfer of Power storyline, a magical version of Jenny appeared and temporarily removed all mechanical weapons from the Earth. The New 52 In the DC Comics rebooted Stormwatch series, part of their New 52 event, Jenny's shirt was seen in storage in Stormwatch's base. Jenny Sparks herself also makes an appearance in a flashback montage, projected by Adam One, in Stormwatch's "0" edition. The Wild Storm In Warren
