Kingdom Hearts Birth by Sleep
When Terra lands at Olympus Coliseum, he spots a Buckle Bruiser and some smaller Unversed attacking Hercules, and drives them off. When Aqua arrives later on, a Buckle Bruiser attacks. Phil offers to protect her, but immediately runs away, leaving Aqua and Hercules to fight the Unversed off by themselves.
A Buckle Bruiser is a large, bottom-heavy creature with predominantly black skin, though it is almost entirely covered in predominantly blue armor. Its feet, which are covered in gold armor, curl up at the toes and its conical arms are protected by circular, blue and gold shields that it can throw. Its head is spherical, light grey, and covered by a blue helmet with a gladiator-esque, light grey crest and two grey spikes on its sides. The armor on the Buckle Bruiser's midsection is black with gold designs decorating it, and somewhat resembles a belt. Its red eyes are set in an angry expression and the Unversed symbol is emblazoned on the center of its belt.
In Kingdom Hearts Birth by Sleep Final Mix, the Buckle Bruiser receives a palette swap which gives it a red body armor with white highlights. Its two bucklers are now white and gold, and the crest on its helmet is gold as well. Its head is now white, and covered by a red helmet. The midsection armor is gold with black designs decorating it.
Buckle Bruisers use the shields on their arms to deflect frontal attacks as well as for offensive purposes. The shields deflect nearly all frontal attacks, so that magic is the sole effective method to attack from the front. When using physical attacks or commands, it is simplest to attack either from behind, or after the Buckle Bruiser has lunged and is lying on the ground.
