Master Sergeant Megan Valladao arrives at the Director's penthouse along with Airman Shan Vang to escort Garik Shayk to his quarters.

Valladao is polite and warm, in contrast to Vang's condescending manner. She tells Garik she prefers to be called Megan unless commissioned officers are present.

Valladao has light freckles, reddish-blonde hair, and a tinier waist than Vang’s diminutive frame can manage.

We first meet MSgt. Valladao in Book 5 of The Human-Hybrid Project, The Glass Siege.
