The Wonder Twins (Zan and Jayna) are a fictional extraterrestrial twin brother and sister superhero duo who first appeared in Hanna-Barbera's American animated television series The All-New Super Friends Hour. The pair can activate their superpowers by touching their fists and saying the phrase "Wonder Twin powers, activate!" Jayna can transform into any animal, and Zan can become water in any state. The pair also have a pet monkey, Gleek, who assists in their crime-fighting activities.

They subsequently appeared in comics based on the animated series and were later introduced into the main DC Comics Universe. They have since appeared in other media, including the animated series Teen Titans Go! and the live-action TV series Smallville.
