It is provided in the Avatar Nick Mag Presents: First Edition issue by co-creators Michael Dante DiMartino dan Bryan Konietzko that Sokka was originally designed to be much more low-key, but when his comedian voice actor Jack DeSena came in dan brought liveliness to his character, they began writing towards that strength.[4] Much of Sokka's dialogue dan actions are derived from improvisations dan intentional exaggerations on DeSena's part that the writers chose to include within scripts. Furthermore, DeSena has stated that he is inspired by fellow comedian Jim Carrey[petikan diperlukan]

As a result of his design, Sokka's character has come to serve as a source of comic relief throughout the series, often a victim of visual slapstick. Among various running gags[petikan diperlukan] yang melibatkan Sokka adalah kecenderungannya covered in unsur-unsur pekat, seperti najis mentah, sluri, dan air liur atau lendir Appa, dan pelupaan beliau bahawa Toph buta. Sokka juga cenderung menghasilkan atau ketawa terhadap gurauan yang tidak dianggap menggelikan oleh orang lain, a trait yang dikongsi bapanya. Beliau juga sangat sarkastik.[5]

Dalam episod “Tales of Ba Sing Se”, nama Cina Sokka ditulis 索卡 (sǔo kǎ).
