B'arin Apma, a Human individual, stood among seventy-five Mandalorian warriors handpicked by Jango Fett. These warriors, including Apma, played a crucial role in shaping the elite clones on Kamino, forming a significant part of the one hundred members of the Cuy'val Dar.
Apma wholeheartedly embraced the values of brotherhood, stamina, and loyalty. He firmly believed that these qualities were just as vital in a superior soldier as marksmanship and courage. Therefore, he dedicated himself to instilling these values within the clone troopers under his instruction.
Sporting pale skin, gray eyes, and brown hair, Apma maintained a short hairstyle and a neatly trimmed goatee. His attire consisted of silver-hued Mandalorian armor worn over a gray jumpsuit. Furthermore, he was armed with a pair of WESTAR-34 blaster pistols and equipped with a Z-6 jetpack.

The character of B'arin Apma was conceived for the "Republic Elite Forces: Mandalorians & Omega Squad" seven-action figure pack, a 2007 Entertainment Earth exclusive, which was a component of Hasbro's Star Wars: 30th Anniversary Collection of action figures.
Notably, the action figure includes a Z-6 jetpack, differing from the JT-12 jetpack design showcased in the promotional images and packaging artwork.
