 In 2006, a new version of the Wendy and Marvin characters debuted in the DC Universe.The pair work as "caretakers" of Titans Tower one year after the events of the "Infinite Crisis" crossover.The pair (now fraternal twins, surname Harris) seem to be technical geniuses; Wendy mentions in their initial appearance that she and Marvin graduated from MIT on their sixteenth birthday, and in "Teen Titans" #40, Ravager refers to them as "tenth-level geniuses" (compare to DC characters Brainiac and Brainiac 5, both purported to be "twelfth"-level intellects).
