Affiliations Villainy Inc.
Abilities Used a telescopic snow ray to create and reverse blizzards


Byrna Brilyant's scientist father died while working on his invention of "blue snow," a special form of precipitation that freezes everything it touches. This invention was intended to "serve humanity," although precisely how seems rather vague. Thinking to put her father's work to more profitable use, Byrna creates the masculine identity of the Blue Snow Man and unleashes the petrifying power of blue snow upon the farming community of Fair Weather Valley, demanding each farmer's "life savings" in return for the chemical antidote that will free crops, livestock, and people from the snow's effects. The Blue Snow Man is discovered in "his" mountain sanctuary by Wonder Woman, who forces "him" to defrost the valley.

The Blue Snow Man, like many of Wonder Woman's enemies, is sentenced to prison on the Amazon penal colony Transformation Island, but in 1948 she and seven other female super-villains escape and pool their talents as Villainy Inc.; led by the Saturnian slaver Eviless, the evil eight are again defeated by Wonder Woman.

Byrna, also known as the Blue Snow Man, retained her male appearance and name in this second appearance, but what if anything is to be made of her choice of criminal identities is unknown.


Blue Snowman attempted to steal a diamond, which brought her into conflict with Power Girl and Dr. Mid-Nite. She battled them, showing off her new costume and abilities, but was quickly defeated. When the alien Vartox appeared, Blue Snowman smelled his musk and fell in love with him, tearing her mask off. A creature suddenly attacked, and in order to save Vartox, Blue Snowman used her blue snow as a diversion, which caused the monster to devour her. It is unknown if she survived.

New 52[]

Blue Snowman was seen briefly battling Wonder Woman and her ally Hessia with many of her robot minions. She was quickly defeated, and presumably incarcerated.


Blue Snowman was first seen battling Wonder Woman with unclear motives. Unaware that there was actually a person within the Snowman outfit, Wonder Woman ended up accidentally putting Byrna into a coma when she defeated the Blue Snowman. Wonder Woman suspected that the Snowman had been hired by Veronica Cale to disrupt her as she had faced multiple new high-tech super villains lately but Diana had no evidence to prove Cale's involvement.

Sometime later Byrna must have awakened from her coma as she launched an attack on Valentine's Day but was stopped by Steve Trevor and Diana. Under the influence of the Lasso of Truth, Byrna let slip that the decisions to create the identity of the Blue Snowman, counter to her birth sex, was a deliberate one and that she felt insecure about her gender which had alienated her from romance that people experienced on Valentine's Day. Diana informed Byrna that they was not alone in their feelings and introduced Byrna to the concept of Genderfluidity, agreeing to let Byrna go in the hopes that their new revelation may help them find inner peace and stay away from a life of crime.

Powers and Abilities[]

The Blue Snow Man possessed no superhuman powers; she relied upon a "telescopic snow ray" which she used to create petrifying blizzards and a "defroster ray" to reverse their effect. In later appearances the Blue Snowman suit is more of a mech-like armour gaining Byrna an added amount of durability and physical strength alongside the usual snow and ice based weaponry.
