Xaku is a fragmented and spectral Warframe with a hauntingly elegant design, featuring a skeletal structure that appears both ancient and otherworldly. Its body is composed of floating, disjointed parts that hover around a central core, creating a ghostly silhouette. The surface is smooth with a matte finish, adorned with glowing, ethereal energy lines that pulse with a faint, eerie light. The color palette is typically muted, with shades of dark purples, blues, and blacks, accented by the luminous energy that courses through its form. Distinctive design elements include a hollow, mask-like face and elongated, claw-like fingers, enhancing its spectral and menacing appearance.
