Wendy has curly blonde hair, and sports a black shirt with the Team Rocket logo. She wears a white skirt as well as tall white boots and white gloves.
Domino is highly manipulative and a master of disguise. She can take on any persona needed for a job, with her true personality being sadistical. She relishes in the torment people experience when she reveals everything they knew was a lie.
She is also highly tactical, covering every possible way to be identified. She mimicked Elise's behavior to convince Ian to allow her to travel with them, and targeted Brendan due to his desire for approval.
Domino originally appeared as a silhouette, recruiting Brodie to join Team Rocket. Sometime before or after this, she disguised herself as a news reporter to interview Elise.
Domino disguised herself as a girl named Wendy, who was a fangirl of Brendan's. She convinces the group to allow her to travel with them. She is constantly at odds with Ian, but eventually manages to get his approval.
After an encounter with Cobalt, Ian attacked Wendy to reveal that she was a member of Team Rocket. When he stated that Silver told him about her, Domino broke her disguise, and used her originally timid Roselia to viciously battle Ian. She then disappears after breaking Brendan's heart.
She reappears later with Team Rocket attacking Ian. She is defeated by Crystal, forced to retreat. She then goes on a mission with Brodie to the Sinnoh region. She meets up with Silver, her "master's" little brother, trying to convince him to join Team Rocket. Silver refuses as she leaves.
Domino is later revealed to be Team Galactic agent Sird in disguise.
