With the exception of Chiron, the centaurs in Rick Riordan's Percy Jackson & the Olympians are seen as wild party-goers who use a lot of American slang. Chiron retains his mythological role as a trainer of heroes and is skilled in archery. In Riordan's subsequent series, Heroes of Olympus, another group of centaurs are depicted with more animalistic features (such as horns) and appear as villains, serving the Gigantes.
