A female Judomaster, Sonia Sato, appears in Birds of Prey #100 (2007), along with Big Barda and Manhunter who are all recruited by Oracle to break into a Mexican prison. In keeping with the theme of the Birds of Prey group, this Judomaster—unlike the others—is female, which means that a more precise, if not correct name would be "Judomistress" considering the fact that the term "master" is normally limited to men.
In 2008, Sonia returned in Justice Society of America #11 the issue in which her name, origin and powers were revealed. Sonia's metahuman talent allows her to project an "aversion field" which prevents her from being hit by attacks specifically aimed at her. This does not include attacks that have no aim, such as random projectiles and explosions. With the help of the JSA, she stops Yakuza assassins led by Tiger. In her earlier Birds of Prey appearance, Sonia Sato is shown having an above-average mastery of English, allowing her to communicate effortlessy. During her JSA tenure she's shown as unable to speak English, learning only with great difficulties to master a stilted, somewhat impaired command on the language. She is shown in a relationship with Damage, kissing him even after his temporarily healed face was reverted to his heavily scarred one
Sonia's romance with Damage is tragically cut short when he is killed by the reanimated Jean Loring during Blackest Night. Now part of Magog's All-Star JSA squadron, Sonia assists her teammates in repelling the Black Lantern invasion of Manhattan. Sonia and Damage's older brother Atom Smasher search the city for survivors, only to stumble upon Damage, now a member of the Black Lantern Corps, tearing the heart out of a police officer.
After the end of the Blackest Night a greatly distraught and grieving Judomaster plans to revert to her earlier plan of vengeance against Tiger, her father's killer, feeling that without Damage's love she has nothing else to anchor to a happier life. However, she's stopped by King Chimera, who relays her the missing half of Damage's last message to her, recorded before the Blackest Night, in which Grant shares with Sonia his wish to have corrective surgery on his face and build a simpler, happier life with her, wishing Sonia, in the event of his death, a better life. Thus King Chimera is able to convince Sonia to enact Grant's last wishes by leaving Tiger alive (albeit with a severe beating). Furthermore, Sonia decides to improve her English (reasoning that only Damage was kind enough to bear her stilted, slow grasp of language), and after giving her lover a tearful eulogy, she begins to finance several relief funds for the people Damage has unwillingly hurt in the years, attempting to give him closure, using money she "requisitioned" from Tiger before having him incarcerated
