Powers, abilities, and weapons Each Silver Swan has the ability to create powerful sound waves with her voice. Their "swan songs" are capable of devastating a small area of land with their destructive force. By creating a low-level humming, the Silver Swan can form a protective shield around herself that can deflect bullets and projectiles. Unlike the Pre-Crisis version, whose abilities were acquired supernaturally through the god Mars, the two Post-Crisis Silver Swans need their artificial wings to control their flight motion. Each version also possesses an additional ability which makes her unique from the other Silver Swans. Helen Alexandros has superhuman strength. It was speculated that Valerie Beaudry had the ability to rearrange matter with her voice (but she never had a chance to be trained in doing so). Vanessa Kapatelis has sharpened nails and the telepathic ability to control birds. In the DC Rebirth continuity, Vanessa's powers stem from an experimental nanite treatment she received that was supposed to allow her to walk again. Once her mind snaps, the nanites alter her physiology and transform her into the Silver Swan, a cybernetic alter ego. In this form Vanessa can easily match Wonder Woman in a fight and is equipped with a pair of bionic wings which allow her to fly or use their razor sharp edges to slice through targets. She can also project devastating sonic blasts with her voice and has knife edged claws at the ends of her fingertips. The post-Rebirth iterations Nanites can also be used to hack any and every computerized mainframe in the world, Diana commenting her technological interfacing potentially could rival Cyborg of the Justice League. Other versions JLA/Avengers Silver Swan appeared in the JLA/Avengers miniseries as a villain under Krona's control. She attacked the Vision and helped take him down with her magic attacks. After other heroes intervened, the Vision phased his arm through her chest, defeating her. She is then shown bound and gagged by Green Lantern in an emerald energy cell with the other villains, save Sonar who is caught in Wonder Woman's lasso. Flashpoint In the Flashpoint universe, Silver Swan joined with the Amazons' Furies. Sensational Wonder Woman In the digital-first anthology series Sensational Wonder Woman, Silver Swan appears in the story "The Queen's Hive", where she, Blue Snowman, Doctor Poison, and Giganta serve as Queen Bee's generals.
