Brassius is a man with green hair resembling thorny vines and gray eyes with bags under them. He wears a red long-sleeved shirt with a yellow collar, black pants and green shoes. On his waist is a gray vine whip. His Grass type preference is reflected in his thorny hair resembling spiny vines and his shirt having a thorny rose bud motif. His gray vine whip is often held like a portable garden hose, but likely has a dark thorny appearance to reflect his theme of "Every rose has its thorns" taken
