Smallville (TV Series 2001–2011) – David Gallagher as Zan – IMDb.

The Wonder Twins, Zan and Jayna, are teenage alien superheroes who were helpers to the Super Friends that debuted in the Hanna-Barbera animated television series of the same name.

As you may know, Netflix and The CW have entered into a new arrangement in the past year. Hulu actually saw the purge of many of its CW shows last year but Smallville somehow still remains exclusive to the platform. As of the time of writing, all ten series are available to watch on the platform.

The series was never supposed to be about Superman. Instead, the show was really supposed to be about Clark Kent figuring things out as a teenager. Welling explained that he and the production team all agreed the moment Clark put on the suit, his life was figured out. That’s not the story the show wanted to tell.

The Wonder Twins’ are Zan and Jayna, alien siblings from the planet Exxor with shapeshifting ability, but they can only activate them when they touch hands. Zan has the ability to morph into any form of water, while Jayna can transform into any animal. They are both members of the Junior SuperFriends.

Superhero twins Zan and Jayna (aka: the Wonder Twins) show up in Metropolis to help ‘The Blur’ fight crime with their combined shape-changing abilities. But the clumsy and naive teenagers end up botching several rescues, landing Clark in hot water with the District Attorney’s office.

When their powers activate or de-activate, there is a blinding purple light. Elemental Mimicry: Zan has the ability to turn his body into any form of water (solid, liquid, gas). He first transforms into a sheet of ice, causing a speeding limo to sprint out of control.

Animal Morphing: Jayna can shapeshift into animals and insects. She is shown transforming into a cougar (to attack the limo), a ladybug (to spy on Chloe and to fly back to Watchtower) and a dog (to subdue Ray Sacks ).
