Mine would be Rain, or Sun. Rain because i like peace and tranquility, and I would use a sword, Sun because its properties are cool.

Color: Green Characteristic: Solidification (Indurimento) Purpose: "The lightning; one that harshly strikes everything" Known Users: Lambo, Gokudera, Gamma, Leviathan, Verde, Dendro Chilum, Ghost, Torikabuto Description: These flames are the most solid flames and have the ability to harden anything infused with the flames, increasing their offensive and defensive properties. This flame is very unique as it has more of an electrical quality than actual flame, as it is used to electricute opponents rather than burn them. Appearance: Lightning Flames have the appearance of Lightning. The center in an off-white green, and the extremely sharp "spikes" of Flame are a neon dark green in color. They have a tendency to form round shapes with the sharper part flailing around.
