The handle of the Selene is short and pale turquoise and has a white spike on its tip and pommel. The lower half of the main blade is pink toward the bottom, yellow toward the top, and has black edges. It also flares out slightly at its base. The upper half of the main blade is a black cross shaped like the upper half of the Nobody symbol. This cross connects to a sharp, outer blade. It is vaguely pentagonal in shape with concave sides and thin, black edges. Like the main blade, it is pink toward the bottom and yellow toward the tip.
When Saïx enters his berserker state, the top spike on the main blade's cross becomes longer. The outer blade becomes a bit shorter near its bottom and gains an additional thin, yellow edge.
Its name refers to the Titan goddess of the moon in Greek mythology.
Selene's ground combo starts with a side-stepping movement and a sideways slash, followed by a 360-degree spinning swipe and an upward diagonal slash, and ends with a near-vertical slash upward.
The aerial combo consists of a sideways slash, followed by an upward diagonal slash and a more powerful downward vertical slash. This weapon has no -Combo.
