The handle of a Tempête Knife is shaped like a four-pointed, sky blue star, and the blade fans outward into a hammerhead-like shape. The shaft of the blade is yellow while the blade itself is sky blue like the handle and studded with five spikes. These spikes are all silver and the middle one is twice as long as the other four.4
Tempête is French for "tempest", which means a violent, windy storm.
The ground combo of Tempête begins with a quick, upward slash, followed by two extremely fast swipes in turn, in which Larxene swipes up with one set and down with another. It finishes with an agile lunge forward, in which Larxene points her knives in front of her and spins, ending in a flip and a downward slash with both sets of knives.
Much like many of Larxene's aerial combos, it begins with one simple swipe upward, followed by a swipe down with both sets of knives. It finishes with a mid-air flip, arms wildly waving the two sets of knives about.
