Resembling a Yellow Opera, the Gold Beat has intricate gold markings on its body and its hat is black with gold trim.
Like other Heartless of its family, this one comes from the color gold and the music rhythm "beat".
Kingdom Hearts III
Because Gold Beats must summon their sigil before they can perform any attacks, they never cause an immediate threat. That, combined with their low HP and defenses, and relative infrequency of attacks, makes them fairly easy to deal with if done quickly.
Their movement can be erratic, making them somewhat difficult to hit while moving without Combo Master. This can be remedied by using aero magic since it pins them in place, causes extra damage, and will never miss (unlike fire or blizzard magic).
