Dr. Impossible (DC Universe)
Who is Doctor Impossible? On the surface, he appears to be a dark, mirror-image of Mister Miracle. Where Mister Miracle is aided in his fight against evil by a personal super-computer known as Mother Box, Doctor Impossible accomplishes his evil deeds with the help of his "Father Box." Doctor Impossible claims to be Mister Miracle's brother from Apokolips. Origins aside, Doctor Impossible remains a formidable foe and disturbing flip side to the powers of Mister Miracle.
Includes the right leg of Kalibak.
