The Wonder Twins, Zan and Jayna, debuted in Hanna-Barbera's The All-New Super Friends Hour in 1977, where they activated their powers by touching fists and shouting their catchphrase. Zan could transform into water in any form, while Jayna could become any animal. The line survived long after the original series through reruns, comic appearances and nostalgic references, becoming shorthand online for two people combining forces. Today it is reused in memes and edits because it instantly signals teamwork, transformation and playful superhero energy without needing any explanation.
