Young Frankenstein was, at one time, a member of the Teen Titans in-between the events of Infinite Crisis and One Year Later. A picture of him clearly shows him as a younger version of the famous Frankenstein, another DC Comics character based on the famous monster and a member of the Seven Soldiers of Victory. What the connection is between the two has yet to be explained.
He finally made an appearance during the World War III event where he and the other Teen Titans tried to help stop a rampaging Black Adam. Young Frankenstein grabs Black Adam, who then rips off his arms. At that point the Titans leave their wounded to the care of rapidly approaching Greek authorities. J'onn J'onzz, disguised as a medical worker, goes into Young Frankenstein's mind and learns that he's still alive and in great pain. In his last moments, J'onn soothes his mind until he finally dies.
As his remains were being carried away in a helicopter, the helicopter was struck by lightning and reanimated Young Frankenstein. But his body was blown to the bits, and the individual pieces began moving on their own, killing anyone in their path for new flesh. Young Frankenstein was finally able to pull himself back together in Albania, and is now walking on the bottom of the Ionian Sea with a need for revenge.
