Along with Monster of the Aesop there's a tendency for all the monsters in a given show to be male or female; rarely will there be a mixed bag. The exception is if the The Dragon or the Big Bad are a different gender and deign to fight the heroes. And much like Monster Misogyny applied in reverse, guy heroes will only fight guy monsters, and girl heroines will only fight girl monsters. Though girl heroes fighting male monsters is not uncommon either, male is kinda of the default gender for Mooks if not the default gender in fiction. This also tends to follow the predominant gender among the cast. Mostly girl heroines? Then it's female monsters. Mostly guy heroes? Then it's male monsters. Subtrope of One-Gender Race.

Centorea's Mother is a rather youthful-looking centauride with fair-skin, yellow hair, horse ears, large breasts and a lower horse-half body. Her hair is tied back in a bun with three locks of hair loose in the front, her left lock is the longest, her right is middle length and the center lock is shortest of the three. Like her daughter, Centorea's mother disliked the tradition of breeding with the strongest males. She fell in love with a human male that had been brought to her home as a 'teaser' a handsome human male that was used to make centaur females willing to mate with the less than attractive male members of their own race and chose to breed with him over her own kind. This resulted in Centorea's birth. She is introduced when she attempts to enter the Kurusu household to see her daughter, Kimihito and Centorea meet her outside. She thanks Kimihito for looking after her daughter but becomes angry when she finds out that Centorea hasn't found a teaser yet and that she made Kimihito her master. She and Centorea get into a fight to which ends with Centorea challenging her mother to a duel.

From giving each other rocks and not the sparkly kind to singing heartfelt songs, these animals prove that there are lots of ways to go courting. But for Adelie and Gentoo penguins, they also need the perfect pebble to seal the deal. These penguins live on rocky shores and prize these small stones to build their nests during mating season. During courtship, a male penguin will find the smoothest pebble to give to a female as a gift. Instead, they will steal the best-looking pebbles from another penguin and pawn them off as their own. For some species of whale, songs are their romantic gesture of choice. Whales rely heavily on sound to communicate in the water. And when mating season rolls around, male humpback whales will belt out amorous tunes to woo a female. Some research even suggests that males will start to weave complex syntax into songs to convey more information to a potential mate.
They colonize mountainsides and similar places. A pure and cheerful race that loves the blue sky and singing. Unfortunately, most of the time, they only sing for other harpies. Harpies are migratory beings and a race that embodies the notion of freedom, going where they please, when they please. However, due to their air-headed personalities they more often then not forget about their "rules" and just do what they please, with that rule being: "Harpies are not allowed to stay a long time in a place. Harpies have a clawed, opposable digit on the joint of each wing, and the wing at the joint has a "palm" which can curl to some small degree.
