Zac is a main character in Shimmer and Shine.
"Sweet, quirky, and kind-hearted Zac is Leah’s good friend and next-door neighbour. Zac is bright and goofy, but in an endearing way. He has an amazing ability to shrug away the weird genie stuff happening around him, often sharing a ridiculous story from his own experiences to justify the shenanigans Leah finds herself involved in."
Zac has red hair and blue eyes. He normally wears a red sweatshirt, a white and black striped shirt, and blue jeans with black shoes. In the second season, he wears a red and white genie outfit with blue pants and a gold genie lamp necklace.
Zac appears in every episode of the first season. He becomes a less regular character from season two onwards.
