Destiny (Tiffany Mack) is the villainess of "Pour Some Sugar, Zombie", episode 2.16 of iZombie (airdate March 29, 2016). She was the lover of Pablo Balaban, a serial credit card thief and the best friend of Nick "Nick The Stick" Costas, a career criminal who worked alongside Mr. Boss. She worked as a stripper at a club along with Cassidy Kozlowski, Nick's girlfriend. Cassidy was approached by ADA Peyton Charles to testify against Nick, and she loudly proclaimed that she would accept her offer after learning that Nick was cheating on her with fellow stripper Lorelei. Knowing that Pablo would also be sent to prison if Cassidy went through with her plan, the evil Destiny decided to kill her.
After having Lorelei drive her and an intoxicated Nick in her car (which Pablo had bought with the stolen credit card of weatherman Johnny Frost), Destiny saw Cassidy walking down the street while on the phone with Peyton. She then had Lorelei pull over, claiming that she was just going to scare Cassidy, before hitting her over the head with a tire iron.
When Destiny and Pablo were arrested for credit card theft (having been tracked down through their purchase of Pablo's new car), Clive investigated the couple's garage and found various electronic goods the couple bought with other stolen credit cards. Under interrogation, Destiny tried to finger Lorelei and Nick as Cassidy's killers by claiming she had seen them get into the hatchback seen during the attack. But Lorelei, under interrogation, revealed Destiny as the real killer and showed Liv and Clive where she had disposed of the tire iron. Destiny is brought back into the interrogation room, where Clive has the tire iron, having found her fingerprints on it. Realizing she was caught, Destiny confessed, stating that she killed Cassidy to keep Pablo for being sent to prison and that he had no knowledge of her evil plan. Destiny was then arrested offscreen.
