Blue Snowman (a.k.a., Blue Snow Man) is a fictional super-villain who appeared in the DC Comics adventures of Wonder Woman as a woman disguised as a man who uses the invention of "blue snow," a special form of precipitation that freezes everything it touches.

He battled Wonder Woman and was a member of Villainy Inc.

Fictional character biography
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.

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.
