Episodes were written or co-written by a team of writers, which included Nick Malis, John O'Bryan, Matthew Hubbard, James Eagan, Ian Wilcox, Tim Hedrick and Elizabeth Welch.[9] All of the show's music was composed by "The Track Team", which consists of Jeremy Zuckerman and Benjamin Wynn,[2] who were known to the producers because Zuckerman was Konietzko's roommate.[10] Two alternating Korean studios[4] were enlisted to provide animation production support for the series, DR Movie and JM Animation Co.[11]
