The Snow Flame is a game-only Flame that made its first and only appearance in the DS game Katekyō Hitman Reborn! DS Fate of Heat III - Yuki no Shugosha Raishuu!.
Overview
The Snow Flame seems to vaguely resemble Mist Flames in appearance, though they are much lighter in color. The margins of the Flame gradually turn into a light blue color, and there are also some "sparkling" elements inside the Flame.
The Flame has the ability to freeze enemies' Flames; however, this Flame is revealed to simply be disguised Sky Flames, and thus the freezing ability was through the use of Zero Point Breakthrough: First Edition.
