EVA's English voice actress in Metal Gear Solid 3: Snake Eater and Metal Gear Solid: Peace Walker was credited under the name Suzetta Miñet.

Benson explained that she used the pseudonym at the recommendation of the game's English voice director Kris Zimmerman Salter, because of her association with Disney and other family-friendly roles at the time. Despite revealing her identity however, she is still credited as Suzetta Miñet in Delta: Snake Eater. The name itself was based on a pet dog Benson owned in her childhood named "Suzette Monet".
