Ms. Gradenko

Backstory
Not much is known of Ms. Gradenko's childhood or early life; but it is suggested she once was an agent of the Organization of Super-Spies, the OSS, referred to in the Spy Kids series. It is mentioned that the OSS were working on a project code-named the "Third Brain," which could transmit telepathic signals. The agents did not know what the Third Brain would be used for, but Floop, a comedian and former agent, turned it into a programme mission control for robot Spy Kids he was building with the help of his lieutenant and spokesman Alex Minion.

Ms. Gradenko almost certainly had a romantic relationship with Alex Minion; based on their greeting. Ms. Gradenko says "It's good to be back, Alex; let's never have children," which suggests that they know each other and were planning on making love when the Third Brain was completed. However, Ms. Gradenko's encounter with Carmen and Juni Cortez changed this view; she feared all children.

Meeting the Cortez children
Ms. Gradenko turned up unexpectedly at the OSS Safe House, her visit itself a surprise because the Safe House was designed to be undetectable. Ms. Gradenko posed as an ally, saying that she had known Ingrid and Gregorio, the Cortez parents, and she said she had met Carmen as a baby. Carmen had no recollection of Ms. Gradenko; who pushed her way inside, surrounded by her henchmen, designed to protect her. Ms. Gradenko told the Cortez children of the message the OSS had received from Gregorio, their father, which contained the letters "FLOOP." Taking this as meaning Fegan Floop, the comedian, was the villain, Juni felt betrayed and took his anger out on Ms. Gradenko. He and Carmen grabbed explosives and lobbed them at the walls, alarming Ms. Gradenko's henchmen, but Juni noticed a henchman outside destroying and sinking the craft him and Carmen had used to get to the house. Fortunately, jetpacks were available, and Carmen successfully grabbed one and flew off after a henchman Ms. Gradenko had said to give Floop the Third Brain... or so Juni thought. Carmen followed the man but failed to retrieve the Third Brain. She flew back to the safe house, where Juni had knocked out Ms. Gradenko who said that he would never see his parents again. Ms. Gradenko awoke as Juni escaped and she was in a panicked state. A jetpack flew right into her, knocking her off her feet just as she shouted "What's wrong with you? They're just children!" to her henchmen, but her dismissal of the Cortez kids was proven wrong when the jetpack shot into her hair, burning it down to the scalp. Ms. Gradenko stood up and growled in anger as her henchmen sprayed water at her burning hair.

Reunited with her boyfriend
Ms. Gradenko, now terrified of children, sought shelter in Floop's castle, which Alex Minion had just seized control of after betraying Floop and imprisoning him in the dungeons. Ms. Gradenko was now safe and protected by her true lover and ally; Alex Minion himself, who had been in love with her in the OSS and had planned to have kids with her. However, her encounter with the Cortez kids had changed her views and she now just wanted a lover. As Alex was insulted by his business employer Mr. Lisp, Ms. Gradenko put her hand on his shoulder in comfort. Ms. Gradenko was revealed to have lost all her hair, except a strand or two. Her body was also revealing in a red tube dress. Alex welcomed her with, "It's good to have you back, Ms. Gradenko," and kissed her passionately, Ms. Gradenko also said, "It's good to be back, Alex, let's never have children," and Alex slipped his arm round her and she wrapped her arm round him. The couple walked off to look out at sea and kiss.

Victory
Alex greeted Mr. Lisp's investors and Ms. Gradenko provided some eye candy for them, and the group all gathered in the main hall as Alex provided a speech where he stated he valued partnership. However, Floop's voice rang out via speakers, saying he wanted Minion at his office as there was a problem with the robots. Mr. Lisp looked confused and said he had been told Floop was away. Ms. Gradenko looked terrified and put her hands on her hips as she adjusted to the situation. Alex said he would investigate, but Floop turned him into a Fooglie, a mutated monster of his own creation. Minion returned, but he had three extra heads and hands. Ms. Gradenko thereafter seemed to lose romantic interest in Alex Minion and when she was next seen, she seemed to be flirting with Mr. Lisp instead. She had warmed up a seat for Lisp, saying it would be "more comfortable."

Ingrid and Gregorio gatecrashed the presentation, and Gregorio worked out all the individuals before him were traitors to the OSS. Gregorio said he ought to have known Lisp was in charge. Upon hearing Gregorio insult Ms. Gradenko when she told Gregorio his kids had burned off her hair and ruined her appearence, Lisp reccommended that the Cortez parents be killed. Ms. Gradenko smirked sexually and looked at Alex for his view, and Alex wholly agreed.

Just then, Carmen and Juni ran into the hall, but their parents swiftly knocked out all their attackers. Immediately afterwards, the Spy Kids, numbering fifty thousand, approached down the corridor. Lisp proclaimed it was "wonderful" to see his army, and Minion smiled eagerly, and as for Ms. Gradenko, she was hopping up and down gleefully clapping her hands and gasping in excitement.

Defeat
Just then, as Gregorio rallied his family for battle against fifty thousand androids, his brother jumped in through the glass window high above and caused havoc amongst Lisp, Ms. Gradenko and Minion. Ms. Gradenko ran away screaming to protect herself and Lisp rolled off the throne he was on. Lisp then straightened up and Ms. Gradenko brushed glass out of her dress and hair and Lisp commanded the Spy Kids to rip the Cortez family limb from limb. Ms. Gradenko notably looked shocked at this command. At that moment the Spy Kids activated to attack. However, Floop reprogrammed their minds, so they wanted to attack Lisp and his force instead of the Cortez family. The amazed Cortez family watched as the Spy Kids rushed at Lisp, Minion and Ms. Gradenko, then they began throwing the three in the air. Ms Gradenko attempted to save herself before she was seized by clinging onto part of the throne, but the robots grabbed her. Ms. Gradenko was flung like paper into the air and Lisp yelled at Minion to get the robots to let them down. Minion told him that they would no longer listen to him. Ms. Gradenko was flung about more. She died from being tossed about as she is never seen again.
