Information on the cameo
Avatar Roku is the immediate previous incarnation of the Avatar during Avatar: The Last Airbender, whose spirit speaks to Aang on several occasions. He was a noble and moral member of the Fire Nation who was friends with the evil Fire Lord Sozin, the one responsible for wiping out the Airbenders and starting the Hundred Year War, witnessing his rise to power and eventually being killed by him. Roku's spirit regrets not doing what needed to be done about Sozin while he was alive, and encourages Aang to avoid the same mistake by showing no mercy to Fire Lord Ozai, though ultimately Aang finds a way to spare him while still decisively defeating him.
Ditch this brat, and fight someone worthy like Kid Goku!
- He is the second cameo to finish a line for a rapper, after Mr. DeMartino.
