The Convergence Brute is an engineered subspecies of Grey designed for heavy labor. Their genetic makeup shares considerable overlap with Cielioid Boxers, though any direct relation is, at this point, impossible to establish. Study of the Brute genome has consistently pointed to the likelihood that they originated in the Convergence. One distinct upgrade the Brute has over the boxer is the presence of multiple enlarged nostrils to facilitate rapid air intake during acts of extreme exertion. Brutes are rare in Grey clades outside the Convergence, but not entirely unheard of.
Standing at a towering 4 meters tall, the Brute is powerful enough to push over a tree or pick up and carry a cow.
