A Sky Grappler is a vaguely humanoid Heartless with navy blue skin and two large, blue, curled wings. Its head is spherical with a jagged mouth and glowing yellow eyes, and it is mostly covered by a white helmet. This helmet is adorned with two conical, red spikes on either side, two angular, black and red spirals on its front, and a curled, blue antenna on its top. Most of its body is also covered by white and grey armor, with its Heartless emblem emblazoned on its abdomen. The Sky Grappler's legs end in small, red spikes and it holds a gold punching weapon lined by red spikes in each hand.
