Shimmer and Shine

Humans and genies

• Shimmer (voiced by Eva Bella in the US, and Mia Wiltshire in the UK) is an optimistic genie with peach skin, blue eyes, cyan jewels, a purple genie outfit and cold red ponytailed hair. She is enthusiastic and encouraging. She loves cleaning, playing the tuba, and collecting genie bottles, and hates glitter, unlike her older sister.
• Shine (voiced by Isabella Cramp in the US, Elie Simons and Mia Hope in the UK) is a courageous genie with peach skin, purple eyes, pink jewels, a teal genie outfit with yellow shoes and blue ponytailed hair. She is an animal lover and is often hungry. Her pet is a Bengal tiger cub named Nahal. Due to her love of animals, she is very knowledgeable about the behaviors of magical creatures native to Zahramay Falls. Unlike her younger sister, she hates cleaning and glitter. A running gag involves Shine saying "It's like I always say..." only to humorously reveal that she has just made up whatever she says next.
• Leah (voiced by Alina Foley in the US, and Claudia Burns in the UK) is a long blonde haired girl with green eyes who owns a genie bottle necklace on her pink shirt, which includes Shimmer and Shine. Although Shimmer and Shine usually mess up her wishes, Leah is patient and forgiving with her. Originally, she is forced to keep her genie's existence a secret from her close friend Zac, but reveals her secret to him after being transported to Zahramay Falls. In the second season, Princess Samira grants Shine, Shimmer, Leah and Zac's wish to visit Zahramay Falls whenever they want. While in Zahramay Falls, Leah magically dons a genie disguise to avoid detection, as humans are not normally allowed in the falls.

She can grant wishes along with the younger genies. She occasionally rewards genies with magic Genie Gems that can have a variety of magical effects. She acts as Shimmer and Shine's mentor and teacher. Despite Zeta being her self-proclaimed rival, Samira likes Zeta and is willing to give her a second chance at becoming a genie-in-training, which in season three is revealed to be due to her past friendship with Zeta when they were both students under Empress Caliana.
• Zeta the Sorceress (voiced by Lacey Chabert in the US and the UK) is a resident of Zahramay Falls with green eyes and purple hair, who is the main villain and Princess Samira's rival and wishes to replace her as the most powerful person in Zahramay Falls. Zeta is a sorceress instead of a genie, as she has no desire to grant the wishes of others, relying on magic potions and magical items.
• Kaz (voiced by Jet Jurgensmeyer in the US, and Harrison Noble in the UK) is a genie in training who becomes Zac's genie in the second season. In contrast to Zac's easy-going and adventurous personality, Kaz is more cautious and scared easily. Despite their contrasting personalities, Zac and Kaz work well together and the latter can be brave when he has to be. His cautious nature also means he puts more thought into how he grants Zac's wishes. Kaz has a pet Ziffilon named Zain, who summoned by one of Zac's wishes after he learned that Kaz always wanted a Ziffilon as a pet.

Though he is reluctant to work with Leah and her genies at first, he eventually learns the value of teamwork from them.
• Nila (voiced by Mila Brener in the US, and Kimani Arthur in the UK) is a mermaid who lives in the waters near Zahramay Falls. Leah and her genies befriend Nila after Leah wishes to find a mermaid after learning they are real. She helps the girls obtain the Mermaid Gem, which allows them to transform into mermaids at will.
