The figure’s gender was not known

Harry had taken one step toward it when a slithering sound made him freeze where he stood. A bush on the edge of the clearing quivered.... Then, out of the shadows, a hooded figure came crawling across the ground like some stalking beast. Harry, Malfoy, and Fang stood transfixed. The cloaked figure reached the unicorn, lowered its head over the wound in the animal's side, and began to drink its blood.
"AAAAAAAAAARGH!"
Malfoy let out a terrible scream and bolted -- so did Fang. The hooded figure raised its head and looked right at Harry -- unicorn blood was dribbling down its front. It got to its feet and came swiftly toward Harry -- he couldn't move for fear.
Then a pain like he'd never felt before pierced his head; it was as though his scar were on fire. Half blinded, he staggered backward. He heard hooves behind him, galloping, and something jumped clean over Harry, charging at the figure.

The figure’s gender was not known, so the four of the highlighted were used in the sentences, weren’t they?
