Bertilak is a tall, broad, and muscular man standing at 6 foot and 6 inches in height. He is described as having a green mohawk and matching goatee. He wears a brown, hooded cloak, a green chest plate over a black tunic. Bertilak has a long scar along his right forearm.
Bertilak's personality is that of a bully - he is shown to be confrontational and hostile towards others, such as Team CFVY, and is easily angered due to his impatience and temperament. Bertilak is arrogant and demeaning of others, as well as someone who is racist towards the Faunus. Additionally, he appears to be quick to hold grudges.
Bertilak enlisted to train at Shade Academy, in Vacuo. There, he and his partner, Carmine, graduated and became fully fledged Huntsmen.
At some point, an unknown hirer approached the two with a job offer involving trafficking people with highly potent Semblances for an as of yet unknown reason. The two of them accepted and targeted Edward and August Caspian, eventually encountering the two in the settlement of Sumire in Vale. Bertilak and Carmine feigned friendship with the two and followed them into the Vacuan settlement of Feldspar, where the Huntsmen encountered Team CFVY.
Carmine and Bertilak aided the Huntsmen-in-training lead the nomadic tribes to the settlement of Coquina, but turned on them when a sandstorm blew over, allowing for an opportunity to complete their original objective. Bertilak attempted to kidnap Edward but was then defeated and arrested by Fox Alistair in a battle inside the sandstorm. His weapon was destroyed in the process.
