|Last appearance||The Beginning|
Naomi is Rachel's mother and works as a lawyer.
Naomi is the mother of three girls: Rachel, Jordan and Sara. She is divorced from Dan, her former husband, who works as an anchorman in another state. Dan is Steve Berenson's brother, thus making Rachel and Jake Berenson cousins.
- "My mother's a lawyer, and she brings work home a lot so she can be around me and my two little sisters. She and my dad are divorced. I only get to see my dad a few days a month, so mom feels guilty when she isn't there for us."
Naomi works as a lawyer, and tries to bring home her work in order to spend time with her kids. While Naomi loves her children, she happens to be unusually polite with Dan during the times which they meet. She was also once described as more accustomed to the 'yuppie' life, as exhibited from her experiences while hiding with the Hork-Bajir valley.
After the Yeerks discovered that Animorphs were in fact humans and not Andalite bandits, the Animorphs had to evacuate their families. After moving Cassie's parents, Rachel's family was alerted. In contrast to Jordan and Sara, who are immediately excited by the Animorphs and especially Ax, Naomi is skeptical of the Yeerk threat to Earth. Rachel begins to morph into a grizzly bear to prove their story; Naomi tries to rescue her children by lunging at Rachel with a spice rack, much to her daughter's amusement. Rachel, with Ax, Jake, and Tobias' help, ultimately manages to move Naomi and the girls.
Naomi finds herself uncomfortable with the Hork-Bajir colony, attempting several times to restore what she sees as human order to the small, hunted community. She is tasked with educating the Hork-Bajir, which becomes a source of irritation to her. She tries to escape the Hork-Bajir valley numerous times. Naomi also tries to make a Hork-Bajir Constitution, but it ends with bad results.
Out of all the parents, she is one of the most opposed to Jake as the leader of the human resistance. She disapproves of Jake and the other Animorphs fighting the war, and believes it should be handled by the authorities. Her arguments frustrate Jake and Rachel the most. Rachel eventually lashes out at her. They later reconcile.
Naomi is still unaware of Jake's crucial decision to order Rachel to kill Tom by herself on Blade Ship; a decision which resulted in the deaths of both Tom and Rachel. When the Andalites brought Rachel's remains back to Earth, Cassie accompanied Naomi to identify her body. Later, during Rachel's funeral, Naomi tearfully allows Tobias to take Rachel's ashes with him.
- Naomi is the only Animorphs' parent to have the same first name in both the book series and the television series.
- Naomi is introduced by name in Book 7. She and her ex-husband Dan get the earliest in-series mention of their names, which is likely part of the reason her name is the same in the books, tv show, and early promotional materials. Other than Marco's mother, most of the rest of the parents are introduced by name in Book 50.
- According to Rachel Naomi isn't a very good cook
