Echo was created by InGen as an attraction for the Jurassic World park. In her youth, she once battled Blue over control of the park's Velociraptor pack, but Blue was the victor and all Echo gained was a scar across her face. Her jaw became permanently offset from the battle. Due to her permanent sneer, some of the Jurassic World dinosaur handlers have nicknamed her "Elvis". 
Echo and her packmates were used to stop the genetic hybrid Indominus rex's rampage. However, Echo and her packmates were able to communicate with the hybrid, who orders them to attack the humans following them. She then attacked the driver's side window of MVU-12 while Claire Dearing was still inside the vehicle while Delta attacked the back, killing an InGen trooper. She then went to attack the mobile veterinarian vehicle MVU-12 where Echo attacked the driver's side of the vehicle, trying to kill Claire Dearing, who was driving the car.
They later caught up with Owen, Claire Dearing, Gray Mitchell, and Zach Mitchell, but when the Indominus orders them to attack again, they instead followed Owen's orders. Sadly, Echo was overpowered and thrown into one of the restaurant's burners where she was incinerated.
