  • Ryu has been credited by Bryan Konietzko as the one who conceived fartbending, an airbending technique employed by Tenzin and Pema's son, Meelo.[1]
  • Ryu's creative insight has been influencing the Avatar franchise for far longer than the beginning of The Legend of Korra: he created the original character design of Jet,[2] suggesting that he has had a part in the show since quite early in production.
  • Interestingly, Ryu's name has been worded as "Ryu Ki Hyun" by Konietzko on occasion,[1] likely in concern to Ryu's Korean origin; Korean names are spoken in a format that starts with a surname, followed by the given name.
  • The design of the character Ryu was based on Ki Hyun Ryu.[3]
