The Beginning


Jonathan Whittake

"He was a good guy, my dad. Not just because he was my dad. Because he was a good person. Because he did his work as well as he knew how and wasn't a jerk to the people around him. That doesn't make you a saint or anything, but I guess when I think about it, that's what I hope I'll do when I'm older: treat my family right, do my job well, not be a jerk to the people I meet."

Dr. Steve Berenson is the father of both Tom and Jake, the husband of Jean, brother of Dan and uncle to Rachel, Sara, Jordan, Saddler, Justin, Brooke, and Forrest.



"My dad's never been my doctor. I go to one of his partners. You know, it'd be creepy otherwise. I'd always thought it was pretty cool that he was a doctor. But I guess I hadn't really thought much about it. On this day, though, there wasn't much else to focus on. So I focused on my dad. Always nice. Always gentle. Joking with the kids and reassuring the moms and dads. Staying calm while the littler kids screamed bloody murder and vibrated the very walls."

To be added

Andalite-Yeerk War[]

"Jake's parents, Jean and Steve, didn't make it out in time. Their chances of escape were slim from the beginning. See, Jake's older brother, Tom, has been a human-Controller since the early days of the invasion. Even with the enemy under his own roof, Jake had managed to protect his parents from the Yeerks. And from their own son, their own first child. Because Tom wouldn't have hesitated to kill either one of his parents if the Yeerk mission required their deaths. Jake had done an almost superhuman job of protecting his parents. Both from death and a fate worse than death. Infestation. Until the last time. When the Yeerks finally took them."

After the Yeerks discovered that Animorphs were mostly humans and not all Andalite bandits, and managed to discover their identities as well, the Animorphs had to evacuate their families. While the Animorphs were collecting Cassie's and Rachel's families to relocated to the Hork-Bajir valley, the Yeerks captured and infested Jake's parents.[1]

It is revealed Jean and Steve survive the war in The Beginning, as Jake lives with them temporarily. 


  • On the Animorphs television series, Steve is named Greg.
  • Steve is also called Greg in earlier promotional items, such as the Animorphs Alliance handbook, and Jake's Animorphs ID card.
  • Jake's father is mentioned many times in the series, but he is not called by name until The Ultimate.
  • In Elfangor's Secret, Rachel mentions that her father Dan is Jewish, and in The Conspiracy, it is mentioned that Rachel's father and Jake's father are brothers, therefore making Steve Jewish as well.
