Also known as: 仮面ライダーガタック, ガタック
Kamen Rider Gatack - Arata Kagami - is the fifth Rider in Kamen Rider Kabuto, as well as the second Rider (besides Kabuto) to transform with a belt. Gatack has a black-and-blue color scheme, a red visor, and is patterned after a stag beetle, as evidenced by a pair of stag beetle horns on the sides of his helmet.
