History[]
Katherine was the only daughter of U.S. military scientist Dr. Wilder and Claudette.
In the years that followed Katherine eventually became a physician at the Metropolis Health Plaza.
Her father worked on a project called "Valhalla" which was the choosing of three infants being induced with a dormant synthetic mind controlling virus that gave them free will to control themselves, leaving them with only a rash as an aftereffect.
But when the subjects were induced with a particular serum, it would make them mind controlled vegetables and use them as assassins whenever they heard the word "warrior".
However Dr. Wilder had a change of heart about the project and along with his friend Dr. Golden decided to terminate it.
The secret was kept for twenty years and during that time Dr. Wilder died from unknown causes and requested that the files of the project should be destroyed.
However Katherine's greedy, sick-minded mother saw this as an excellent way to make money and persuaded her to help with this evil scheme.
Season 2[]
Katherine and Claudette stealing the Valhalla Project file after killing Dr. Golden
Katherine searched the file room for the files, but was caught by Dr. Golden who persuades her not to go through with it and that tampering with people's lives was dangerous. However Claudette appeared with her henchman Klaus and said this would be her reward for being the "dotey military wife". She persuaded Dr. Golden to be part of it, but he refused and once again tried to persuade Katherine to stop this horrible plot, but was fatally shot in the back by Claudette.
They opened the file and found three subjects: G.E. Mallow, Sarah Goodwin and Jimmy Olsen.
At the plaza, Katherine worked to make the tysion serum that would awaken the mind controlling virus deciding to test the validity of her father's work. Claudette appeared again saying she has made a deal with a client named Mr. Moonhauer She promised him great power with the serum and virus that would make his people mindless vegetables for him to control.
Claudette and Katherine were able to activate the virus in all three subjects. The first subject, G.E. Marlow, died while attacking Superman after an apparent overdose of the serum. Klaus had also been caught by the Man of Steel Meanwhile Sarah and Jimmy were given orders to take out top Daily Planet reporters Lois Lane and Clark Kent.
Sarah tried to kill Clark with a revolver, but his super speed and strength as Superman caused her to fail. Meanwhile Jimmy was making his way to Lois' apartment with Katherine, Claudette and Moonbauhen close behind. DEA investigator Dan Scardino was there to pay Lois a visit. He saw Jimmy going up and said hello, but was hurled down the stairs.
Claudette and the others caught by Dan Scardino
Jimmy entered the apartment and tried to kill Lois with a sharp cutting knife, but Superman arrived just in time and stopped him. A scared Mr. Moonbauhen fled. To keep the Man of Steel from catching them, Claudette made a diversion by ordering Jimmy to jump out of the apartment window.
While Superman was saving him, Katherine and her mother made their escape as well, only to run into Scardino who had recovered from his fall and was now in the hallway holding Moonhauen at gunpoint. He then placed the Wilders under arrest as well.
They were presumably imprisoned after this with Katherine losing her job and profession after her illegal doings at the Health Plaza while Jimmy and Sarah were cured once and for all from the virus and her late father's research was destroyed for good.
