The original story outline that I wrote for the Fall of Superior Girl story.

Where does it begin?

Superior Girl begins shortly after JulieVelor's original story stopped being updated.  Jessie has resolved the issue at the ranch that Lex Luther had assigned to her, and has since returned to Metropolis.  She ultimately chose not to enhance the two girls out in the ranch, even if she did eventually have her fun with them.  Jessie has decided to return to Metropolis in order to get Michelle fully activated.

Initial Story Outline

Superior Girl is able to convince Michelle to take the ambrosia in order to become an Ambrosia Amazon. However, Michelle refuses to take it in the same method that the other girls did, and simply drinks an accumulation of it from a glass.  The ambrosia immediately causes her Kryptonian genes to begin activating, which results in a tremendous explosion of energy that destroys both lab and knocks Jessie unconscious.  When she comes to, Michelle is nowhere to be found beyond scorch marks on the floor where she was standing.  Jessie sadly assumes that something went wrong with Michelle's mutant genes, which resulted in her death.

Michelle wakes up miles outside of Metropolis in a heavily wooded rural area somewhere near Smallville. Devastation is all around her from where she crashed.  She begins to explore her new found Kryptonian powers that have now fully manifested.  Michelle goes into town to steal clothes and get back home.  While there, she is found and approached by Superman in the guise of Clark Kent.  Clark reveals to Michelle that he is actually Superman, and that he needs her help.

Clark explains to Michelle everything that Jessie has done with the powers that she got from Supergirl, whom he presumed she killed.  Michelle comes to realize that Jessie truly is a villain, and more monstrous that the press had made her out to be.  She flies with Clark back to the Fortress of Solitude to research her powers and begin training her in their use.  While at the Fortress, they both learn that she is half-Kryptonian through her father.  She also quickly becomes adept at using her powers, and finds that she too is much stronger than Clark.  Ready to face Jessie with the help of Superman, Michelle takes on the name and costume of Power Girl.

Taking down the Amazons

Michelle begins her campaign to take down Jessie by going after Terri Suzuki, one of the Ambrosia Amazons.  Michelle dons the Power Girl costume, and confronts Terri at a nightclub in Singapore that Terri is visiting while on business for Lex.  Power Girl is able to subdue Terri, but not before a fight erupts in the club that is posted online by partiers.  Michelle flies Terri back to the Fortress of Solitude in order to run tests with Superman.

After seeing the video, Jessie goes on a hunt for the mysterious woman that kidnapped Terri.  She is unable to find any trace of Michelle in Singapore, and decides to investigate Superman at the Daily Planet. Monica and Caroline are able to confirm that Clark Kent has been a regular at the Daily Planet with regularly written stories, and his alter ego Superman has been seen around the world stopping disasters.  What she does not realize is that Superman has been holding off sleep for days, and both Lois Lane and Lana Lang have been helping him write stories to make it appear that he is working.

Back in the Fortress of Solitude, Michelle finds that the Ambrosia permanently altered Terri's DNA so that it is impossible to reverse the process.  Michelle has Terri locked up in the Fortress so she can be kept out of sight until she can be turned over to the authorities.  She then has the computer provide information about Caroline and Monica who are working with Jessie.

Power Girl flies out once again in order to take down Caroline.  Power Girl flies to a known safe house used by Lex Luthor's more nefarious underlings in India.  She assaults the safe house, and quickly demolishes the entire building.  She then flies towards another safe house in India, and performs the same action.  However, at the second location, she tells a survivor that she is going to shut down each safe house in India in the next 48 hours and dares Lex's pet to stop her.  Upon hearing the news, Jessie immediately flies to India to confront Power Girl, who has quietly slipped out of the country.

While Jessie searches for Power Girl in India, Michelle doubles back to Metropolis during the night while Caroline is working late.  Power Girl confronts Caroline who is joined by Monica.  A fight breaks out that trashes an entire floor of Lexcorp offices.  Power Girl uses her heat vision to burn off one of Monica's arms, and Caroline is left bloodied and unconscious.  Power Girl breaks into Lex's secret data center under the building, and steals as many hard drives that she can carry.  Jessie returns too late to find a battered Caroline and maimed Monica.

Power Girl returns to the Fortress of Solitude where she has the computers examine the hard drives.  Using information provided by Caroline, the computers are able to decrypt the hard drives and learn that Lex Luthor was behind the plots to kidnap Caroline and Jessie.  The goal had been to discover any weakness while also using the situation to keep them close to him.  Determined to bring Superior Girl down at any cost, Power Girl convinces Clark Kent to have the Daily Planet publish the data that Superior Girl works for Lex Luthor and that he was also working against her.

The Final Confrontation

With the news being broadcast around the world that Lex had his own employees kidnapped and hired a supervillain, the police surround LexCorp headquarters in order to arrest him.  Jessie flies to LexCorp offices and confronts Lex herself with both Caroline and Monica.  In a fit of rage, Jessie kills Lex Luthor.  She then flies down to the police waiting outside and declares herself Superior Girl, new ruler of Metropolis.  The police open fire on her, and she begins demolishing them.  Superman arrives to try and stop her, but is quickly defeated through Jessie's rage-filled strength.

Jessie returns to LexCorp offices, and has every female employee brought to her.  She reveals stores of ambrosia that she kept hidden.  She then offers to enhance any woman that will follow her, and selects some of the more beautiful women for personal enhancements.  Soon Jessie has a small army of super-powered females that she unleashes upon Metropolis in order to take control.  While this happens, the National Guard is brought in to fight them.

As chaos enveloped the city, Power Girl and Superman arrive and begin to confront the super-powered followers of Jessie.  Multiple battles begin at Power Girl and Superman are able to fight and subdue many members of Jessie's new army.  Deciding that they need to stop the problem at the source, Power Girl flies off to LexCorp to confront Jessie while Superman works to stop the superwomen in the streets.

Power Girl arrives to find Jessie with Caroline, Monica, and two other enhanced women.  An epic battle breaks out between each of them that completely devastates and demolishes the LexCorp building.  Havoc is wrecked throughout the city as Jessie and Michelle fight each other.  Caroline and Monica are both killed during the fighting.  Power Girl proves herself to be stronger than Jessie due to her years of weight lifting while her Kryptonian genes were suppressed.  Jessie is finally knocked unconscious, and Superman is able to quell the remaining chaos.

Aftermath

Power Girl, Superman, and Jessie travel to the Fortress of Solitude.  Using the data stored in Lex's hard drives, the computers at the Fortress are able to reverse engineer the process that was used to steal Supergirl's powers and give them to Jessie.  Superman is able to determine that a transfer between Kryptonian to Human would be fatal, but a transfer from Human to Human could be done safely.

Superman brings Lois Lane to the Fortress of Solitude, and uses a replica of Dr. Mendenhall's machine to transfer the Jessie's superpowers over to Lois Lane.  Lois emerges from machine totally invigorated with the full powers of a Kryptonian.  After testing her powers, Superman, Power Girl, and Super Lois decide to experiment with their powers in other ways while having a threesome.  Afterwards, Super Lois takes on the identity of Superwoman and become a superhero herself.  A now normal Jessie is then taken to the authorities in order to face judgement for her crimes, which Lex had kept explicit and detailed records on.
