Wondertwins
The Wonder Twins, Zan and Jayna, are fictional extraterrestrial cartoon superheroes created by Hanna Barbera for the Super Friends TV program. As the other characters on that show were published by DC Comics, they have strong comic book associations. Their first comic book appearance was in Super Friends #7 (October 1977), by E. Nelson Bridwell and Ramona Fradon. A modernized version of the twins debuted in Extreme Justice #9 (October 1995), by Ivan Velez and Al Rio.
