Extreme Justice version

The new, revamped Wonder Twins. Art by Todd Nauck.In the 1990s they were introduced into the main DC Universe in the series, Extreme Justice. The Extreme Justice series retconned their origin so that they are slaves of an alien villain, later rescued by the Justice League. Unable to speak English, they accidentally attacked some civilians and the Justice League. They had far greater powers than their cartoon counterparts. During their fight with the JLA, Zan became an ice golem, a water monster, and a demonic-looking whirlpool; while Jayna became a griffin, a werewolf, and a sea serpent. Although rarely seen today, this version of the Wonder Twins is still part of the current DC Universe. Later they appeared in Young Justice, wearing uniforms which resembled t-shirts and jeans, to help avenge the murder of Empress's parents. Apparently, the Wonder Twins enjoy the taste of CDs, as they ate several of Wonder Girl's favorite discs.
