!!Tropes common in his works:
* AlliterativeName: His full name, too; it's Richard Russell Riordan, Jr.
* AllMythsAreTrue: In the case of his books, Greek, Roman, Egyptian and Norse mythology co-exist in the same universe. There is also a mention of Jesus and Moses is confirmed to exist, though his characters remain officially agnostic on the existence of a "Capital-G God."
** Apollo references the Aztec gods during his own series, as well as the Chinese. An African Pantheon Demigod also appears in Book 2.
* {{Cliffhanger}}: Has a reputation for these (though more often he simply leaves some plot threads unresolved to be built on in later books, which some confuse for this trope).
* DeadpanSnarker: He writes ''a lot'' of these. He's also quite the snarker himself, if [[https://twitter.com/camphalfblood?ref_src=twsrc%5Egoogle%7Ctwcamp%5Eserp%7Ctwgr%5Eauthor his Twitter account]] is anything to go by.
* FirstPersonSmartAss: He likes this trope and uses it semi-frequently
* LoadsAndLoadsOfCharacters: Oh yes. With four distinct groups of heroes and their respective villains, this is to be expected.
* RecycledInSpace: Though he's pretty clever at it, making the blend of ancient mythology and the modern world complex and entertaining.
* ShownTheirWork: Riordan certainly does his research, though he sometimes juggles things around for ArtisticLicense, and the fact that many of the myths have different variations and are often open to interpretations.
* SignatureStyle: His best known books often put mythological figures in a modern day setting and have a lot of humor to them while still making it a fantasy adventure.
* SlidingScaleOfIdealismVsCynicism: His books are on the idealistic end of the scale.
* {{Troll}}: The fandom is fond of calling him one, due to his penchant for cliffhangers. He takes it well, though.
-->'''''House of Hades'' dedication page:''' To my wonderful readers: Sorry about that last [[IncrediblyLamePun cliffhanger]]. Well, no, not really. HAHAHAHA. But seriously, I love you guys.
* WorldOfBadass: To be expected when the world has four distinct groups of heroes who get involved in epic battles with their respective villains. And that's not even counting the gods, monsters or other creatures, heroes of the past, and [[HeroesOfAnotherStory non-protagonist characters]] all with their own (albeit not always as interesting) adventures and abilities.
* WorldOfSnark: Contributing to plenty a CrowningMomentOfFunny.
