Appearance

Personality
Judy is normally and upbeat, affectionate and friendly individual. She has a fairly blunt, straightforward personality.

However, when acting as a Durpa agent, Judy is shown to be emotional, cruel and violent.

Stray Sheep
Judy is implied to the the one responsible for attacking the lab on New Years. She storms the lab with DURPA agents and breifly captures Kagari. After Yugo arrive and takes down several agents, she is attacked by Suzuha, allowing Kagari to go free. She then retreats.

Orbital Eclipse
She first appears when she follows Maho, suddenly hugging her from being and scaring her. When Okabe arrives, believing Maho to be in danger, Maho explains who Judy is. Later, during New Years, her and Leskinin arrive at the shrine in order to participate in the festival, however, because they got distracted while shopping, they end up arriving after everything had ended.

Twin Automata
Judy along with DURPA agents attempt to Capture Maho, but are stopped by the intervention of Okabe and Yugo. After Maho makes it back to the Tokyo Denki with Leskinin, Judy corners them, immediately killing Leskinin and threatening Maho to transfer control of Amadeus over to her. Maho ends up doing so, but before Judy can kill her, Moeka arrives and her and Maho retreat. Judy then waits for Amadeus to reboot only for it to be revealed that Control of Amadeus didn't actually transfer and both [Kurisu] and Maho were just buying time. Judy is then held at gunpoint by Maho while Moeka watches the door. Judy manages to trick Maho and take the gun from her, one again threatening to kill her and shooting Moeka for good measure. Maho seemingly agrees to transfer control over, but instead deletes Amadeus entirely, revealing that transferring control over Amadeus was actually impossible from the start. Judy is then shot by a still alive Moeka and falls unconscious. Because Moeka shot her in a non-vital area, Judy survived, but Mahao doesn't know what happened to her, suspecting that the CIA of FBI may have intervenes.
