Behind the scenes
Centaurs were creatures of Greek myth. Their appearance in My Little Pony media is likely a visual reference t the equine ponies, but also contain devilish or "demonic" physical characteristics, such as dark red fur and horns. The first centaur to appear in the franchise was Tirac in "Rescue at Midnight Castle", and so far, all centaurs in the series have direct connections to him and his family in some capacity. Centaurs first appeared in the series hen the series largely drew from European mythology to develop its initial setting.
