Riki is one of the seven protagonists and playable characters in the video game Xenoblade Chonicles. He is a member of the mercantile Nopon race and the latest chosen Heropon. Although he looks like a child, he is actually 40 years old and has a wife and at least six children. A natural story-teller, he will go on at length about how he is actually a legendary hero spoken of in Nopon prophecy. He seems to eat a lot despite his small size, a trait shared by his children, and he accompanies Shulk and the group as a way to pay off the heavy debts that have arisen from this. Ironically, despite being the 'mascot' of the group, he considers the others his sidekicks.
He is voiced by Yuki Kaida in the Japanese version and Wayne Forrester in the English version.
Riki, despite being 40 years old, is still a child at heart. He is always cheerful even during tough battles and will encourage his friends to keep on fighting. Riki is egotistical, always taking credit for major battles despite his friends mostly doing the hard work for him.
- Riki reappears in Super Smash Bros. for 3DS / Wii U as an Assist Trophy character and part of Shulk's Final Smash Chain Attack; in the former, Riki uses various Arts that cause random effects.
