Nadare Rōga

is a Snow ninja who works for Doto Kazahana alongside Fubuki Kakuyoku and Mizore Fuyukuma. He seemed to have previously met and fought Kakashi Hatake. At that previous time, Kakashi was forced to retreat since he could not defeat all the Snow ninja alone. Nadare frequently mocks Kakashi because of this years later. Due to his chakra armor, he was able to counter Kakashi's Lightning Blade. However, Kakashi seems to kill him in battle through taijutsu, crashing him into the rocks underneath. But since it wasn't confirmed, we can't be sure that he died.

He seemed to be overly arrogant, even naming one of his jutsu after himself, however, his name does describe the technique rather accurately. "Nadare" (雪崩) means "avalanche" while "Roga" (狼牙) means "wolf's fang".

Trivia

 * He bears a superfacial resemblance to Akahoshi, the main villian of the Star Village Saga which is exclusive to the anime.
