Natalie Lee is a scientist at B.A.S.I.C.S. Labs and a former scientist at Venuna Labs.

Relatives
Natalie is the daughter of the late Stephanie and Robert Lee, the ex-wife of Cheesy Maasdam, and close friends with Shadow, B Frit, Cade Verde, Sir Benelux, Robbie Stevens, Foury Frit, and Joey the Grasshopper.

She is also the former lover of "Antonio Sea", before discovering his true identity as Sheldon Plankton, and the ex-girlfriend of Diphine, a ricebodied birdectalyte.

Biography
When B Frit was electrocuted by the debris from the exploding laboratory, she took him to her workplace, knowing he would get along just great with her friend, Shadow the Ant.

After B Frit began his crusade as "InstAnt", Natalie became a member of his team with Shadow and Dr. "Baldi Baldimore", before discovering the latter's true identity as Hornet Wings, and provided medical support for the team.

In the InstAntpoint timeline, Natalie is not a scientist but a doctor who is unwillingly brought into Ant Industries by B to help him restore the timeline.

Following B's attempt to restore the timeline, Natalie is once again a scientist at B.A.S.I.C.S. Labs, but she also has abilities similar to Anti-Natalie Lee, who she is afraid of becoming like.

However, it was later revealed that her powers were dormant all along due to her father using an experimental cancer treatment on her, when she was 10. After being taken over by her rising anger while using her powers and losing control of her emotions, Natalie briefly started going by her doppelgänger's name, Killer Silo.

After suffering a clinical death from a seizure and subsequently being revived by her regenerative powers, her biochemistry was altered, culminating in her becoming fully consumed by her anger as Killer Silo, later encountering and allying with Arunasura after the proclaimed god reveals his true identity as a future version of B Frit.

Later, between Shadow giving Natalie the choice to cure herself rather than force it on her and watching Arunasura nearly kill him, Natalie finally regained her true personality and control of her powers.

Despite this, Natalie decided not to take the cure. Feeling lost to her own identity, Natalie left Team InstAnt on good terms to rediscover herself. Six months later, having seemingly come to terms with her mistakes as Killer Silo, Natalie finally decided to re-join Team InstAnt.

Shortly after returning to Team InstAnt, Natalie once again began to struggle with her Killer Silo side and eventually lost control.

Foury convinced both Natalie and Killer Silo that they could try to be the same person instead of choosing one life or the other. As such, when preparing to serve as back up to B along with Shadow, she emphasized that both herself and Killer Silo were prepared to work together to help.

When Benelux Hitler and his army crashed B and Foury's wedding, she aided her friends in the battle that followed, earning Max the Fly's affection.

In a battle against Zavun de Fauven, she lost her Killer Silo side as a result of Zavun using Tomodachidude's powers to create a mental block. After defeating Nazi Cape, Natalie discovered that Killer Silo is still inside her. She later learns, from a suppressed memory, that Killer Silo has been with her since childhood.

After defeating Zavun and getting Joey back, she discovered that her father's death certificate was a fake and that he was actually alive.

B, Shadow, and Natalie eventually found him hiding out in an old warehouse. However, he later revealed himself to an evil alternate personality and attempted to kill the team and take over Robert's body completely.

During the fight, Natalie managed to break through the mental block that Zavun had created and regain Killer Silo. By late 2020, she'd begun referring to her alternate persona simply as "Silo".
