Frost Moth is the Omnitrix's sample of a Necrofriggian from the planet Kylmyss.
| name = Frost Moth | backcolor = green | textcolor = black | image = | species = Necrofriggian | home planet = Kylmyss | body = Moth/Butterfly | power = Ice breath and flight. | voice = Dwayne Johnson | 1st-appearance = Washington B.C (Chris 10)He looks like Big Chill in OV, but he is a lighter blue. And he has frost come out of his mouth whenever he talks. Unlike Big Chill, he doesn't have a cloak. He still has his mask from OV, and he has a German accent. He wears the Omnitrix on his chest, and he doesn't have a belt. And his spots are now, and forever white.
He can fire ice from his hands and mouth, and he can also fly, like regular moths do.
He can be weakened from fire and lava. He isn't finger strong, so he can't climb anything.
- Washington B.C (Chris 10) (first appearance) (accidental transformation; selected alien was Block Buster)
- He is based off of Big Chill. (duh)
- He is Chris' favorite flying alien.
