Zelda is the main antagonist of the 2013 live-action/animated film, Okidooge Island 2. She's the ruler of Eagle Island, and Mighty Eagle's ex-wife. She becomes increasing frustrated with the frozen environment living on her polar island. She plans on turning both Okidooge Island and Baboon Island into her own resorts, full of summer fun.
In the 90s, Might Eagle and Zeta met each other in high school and they both started dating. They enjoyed each others company until one day Zeta proposed to him. After married at the altar, Mighty Eagle, in his cowardice, saw darkness in her heart, so he fled and left her. After the divorce, she gave birth to to their daughter, Debbie afterwards. Later, Zeta's pride dissolved into rage, and she rampaged through the Lemur Island, laying it to waste, and thus killing Lemur's parents, but their son escapes and is washed away to Okidooge Island.
Being fed up with her cold upbringing, Zelda shoots ice balls at Okidooge Island and Monkey Island to force their inhabitants to evacuate.
Chuck and Bomb ask Red to speed date, where he meets Chuck's sister Silver and an excellent engineering student, but she deems him incompatible. Red quits the meeting and finds Leonard, the king of Piggy Island, comes to his house to negotiate. Red reluctantly agrees to build an alliance with the pigs and they recruit Chuck, Bomb, Silver and Mighty Eagle. They hold a special meeting in Mighty Eagle’s cave. When Red shows a photo of Zeta, Mighty Eagle behaves abnormally. The meeting is disrupted when Zeta's ice ball hits Eagle Mountain and destroys it, but they escape just in time.
Later on, the team travels to Eagle Island via submarine. Once there, Mighty Eagle reveals that Zeta is his ex-fiancée that he abandoned due to his cowardice, retreating to Bird Island. Red insists on fighting alone and Silver decides to follow him. They intrude the base from the mouth of the weapon only to be captured by the her guards. The other team members disguise themselves as a Trojan Eagle, grab a key card in a washroom, and get into the base. The guards are driven into a breakdance battle by the disguise's unusual movement, and the team find that Red and Silver were being caught. They are forced to escape when their disguise rips apart, but the guards are too busy dancing to notice.
Zeta tells Red and Silver her plan to fire lava balls at Bird Island and Piggy Island, while the former regrets telling the islanders to not evacuate. After she leaves to start the countdown, Red admits to Silver that he put himself before anyone else as he's afraid of not being liked if he's no longer a hero. Silver frees them both using her hair, reuniting with the team. Red transfers the leadership to Silver, who establishes a plan to destroy the weapon
Silver, Mountain and Lemur put themselves in an ice ball and roll on a rail towards Zeta's super-weapon, but the plan comes apart and it misses the target, and the whole team are confronted by Zeta and her guards. At this time, Mighty Eagle arrives to apologize to Zeta, but she quarrels with him, revealing his name as Ethan and that she raised a daughter he was unaware of named Debbie. While Zeta is distracted, Polly tells Mountain to tie up the weapon using a powerful rope she invented, which catches and decelerates the lava balls when Zeta fires them. As the rope breaks, the monkeys and the animals traveling above Eagle Island help grasp it. The lava balls slide back into the weapon, destroying the whole base. Everyone escapes, and Mighty Eagle protects Debbie from being crushed by a metal plate, but Zeta falls to her presumed death while being blasted by the iceball as a result.
Zeta later came back to life when Lemur destroyed the iceballs, and shows gratitude to the Mighty Eagle and they finally hold a wedding ceremony on Bird Island, with Mountain as the chief witness.
Zelda is a purple anthropomorphic eagle with a fluffy head, green eyes and black eyelashes. She also has a curved light purple beak with three sharp teeth. Zeta has purple and white feathers all over her body.
