In the 1990s, they were introduced into the main DC Universe in "Extreme Justice" #9 (October 1995), by Ivan Velez, Jr. and Al Rio. The series rewrote and updated their origin story. Velez, an avowed die-hard fan of the Wonder Twins, intended to begin a revival of the characters, but was taken off the series after the first issue with the Wonder Twins. Though the twins remained with the series until its cancellation with #18, they were used only sparingly after Velez's departure. Following the cancellation of "Extreme Justice", the Wonder Twins showed up only sporadically in the DC Universe, with their last significant appearance being in 2003.
