Riley was one of the four unique benders whom Yahshi scouted for Team Avatar. Once he had demonstrated his ability to bend cookie dough and impressed Sokka with his skills, the gang began to discuss whether or not to recruit him. However, just as they were about to announce their decision, Riley and the three other benders left to start their own group, deciding that they did not wish to be judged.[1]
Riley is a fanmade character entered in the 2006 Nick Magazine contest where readers sent in their own created characters to be featured in the comic "New Recruits".[2]
