Rikki Kixx (most likely a parody of Mötley Crüe bassist Nikki Sixx and glam rock band Kix) is Pickles' replacement in the band in Snakes 'n' Barrels II and is the de facto leader as well as the episode's villain. It's revealed during a conversation with his aide that he hates the "living hell" that is sobriety due to health and legal reasons, and that if he can't do drugs and alcohol then he'll do anything in his power to make it so that nobody can. He then kills the aide by strangling him, to ensure that nobody knows his ulterior motive for endorsing sobriety. During the opening act of the SOBERTOWN USA concert, Kixx has Pickles detained by security. Pickles later escapes the guard and rushes Kixx on stage. Kixx was then brutally beaten by Pickles as the concert degenerates into chaos. It is not yet known whether he survived the beating.
Unlike Pickles, who did both lead vocals and lead guitar, Kixx only does lead vocals. However, during Snakes 'N' Barrels' performance, he only shouts out "yeah" and "woo hoo", indicating he was not as talented of a signer as he is built up to be nor he did not know the lyrics.
Rikki's dancing style during concerts is most likely a parody of Axl Rose, the lead singer of Guns N' Roses, the band on which Snakes 'N' Barrels was largely based. Based on the name alone, plus his time in rehab and newfound sobriety, it's more likely that Rikki Kixx is based on Nikki Sixx of Mötley Crüe.
Rikki Kixx has a liver problem, preventing him from drinking.
