First Appearance: Wonder Woman 4 (1943)
Creators: Williams Marston and HG Peter
Abilities: Vengeful former slave and aviator with a grudge, a gun and a dagger.
Backstory: Mavis started as an innocent woman enslaved by Wonder Woman’s first recurring enemy, ruthless nazi spy, Paula von Gunther. Growing vengeful in her suffering, Mavis would ultimately prove herself a cunning adversary, determined to even the score.
After Paula von Gunther was found to be a victim of blackmail and artifice at the hands of the Nazis, she and her daughter, Gerta relocated to Themyscira to be free of the fascist regime; But without Paula having to face justice for her many war crimes, such as keeping slaves, Mavis sought revenge against her former captor and anyone who would come to her aide.
Once freed, she would ultimately side with the Nazis, and in order to gain retribution for the abuse and subjugation she had endured, Mavis (told Paula she hated her) then used Diana’s jet to sabotage Paula by kidnapping young Gerta and strapping Wonder Woman to a bomb.
Mavis was eventually caught by Wonder Woman and sent to Reformation Island to reside under the watchful eye of the Amazonian prison warden, Mala; However, she would later escape, seize control over Axis spy operations, trap Wonder Woman, and thinking it would leave Diana unprotected, remove her Bracelets of Submission. Unfortunately for Mavis, they aren’t only used to block attacks. By removing the mystical bracelets, meant to bring balance, she would unleash ALL of the mighty Amazon’s strength, sending her on a frenzied rampage. Which did not end well for Mavis.
