As it's Frösht. Itmight sound Russian. Actually here its story.

He has no name, he's just the result of a test which concerned Barry Allen's DNA and Zoom's DNA to create this one. He's entirely a Speedster and as he was born in the North of Russia, his metabolism is very cold. Yet he survives in cold temperatures he can also set an Ice Trail behind him upon his Lightnings, he can freeze the water beneath his feet and shoot Ice Bolts. All of his Speedster Abilities concern Ice as well. Yet he's a frozen Metahuman he can't normally survive during hot weather or warm temperatures. He needs a special Ice Suit that'll be later given by his friend Mr. Freeze. Frösht is neither a Superhero nor a Villain, but as he's a Weapon to the Russian government he's been taught how to act with seriousness and determination. That's all the story cause I'm really inspired tonight but I hope you like it !
