As Captain Hardrock
Captain Hardrock has long red hair spiked upwards, and they have golden eyes. The upper half of their face is covered with a black mark edged with dark red, and they wear a black bandana with a white spiky-haired skull on the front, along with gold circular earrings.
They wear a body suit that is red from the collar to the chest and black from the chest, the colors' separation looking like flames. The suit includes three yellow buttons vertically on the lower body, three golden spikes horizontally over each knee, and a golden patch above each hip. They have two black belts, one going around the body diagonally and the other wrapped around the waist, that have golden buckles. Over their suit, they wear a black captain jacket with golden inner lining, golden spikes on the shoulders, golden edges, and golden buckles on the sides. Black fingerless gloves with golden edges around the upper holes cover their arms up to their elbows. Their knee-high boots that end below the knees are black and red in a flame-like pattern with black soles, golden heels, black inner lining, and black stripes with golden spikes above the ankles.
For a weapon, they carry a cutlass with a black handle, three thin red stripes on and near the pommel, and a blade with jagged black edges that goes from red at the handle to white at the tip.
