The Question (voiced by Jeffrey Combs) was a superhero and became a member of the Justice League after the Thanagarian invasion. He was known for his "crackpot" conspiracy theories and brilliant deductive skills. He used a special flesh-colored mask that covered his face, along with a special yellow gas that could change the colors of his hair and clothing. The Question was possibly the most unconventional superhero ever to join the organization. He was a paranoid investigator who shamelessly went through everyone's trash, drove a car with no license plates, and believed there was an ominous conspiracy inherent to everything.
