Synopsis:
The Martian Manhunter spots Ivor Sandez, Mr. V's top lieutenant. He follows Sandez, hoping the trail will lead back to his boss. When he reaches one of Vulture's mountain hide-outs, J'onn assumes the form of Sandez. However, a nearby martian meteor causes Sandez to assume J'onn's form and powers.

In the Martian Manhunter's body, Sandez tries to make himself the head of Vulture. In Sandez's body, J'onn is pursued by Vulture agents who believe that he led the Martian Manhunter to their hide-out. J'onn hopes to delay Sandez long enough for the meteor to burn out which will restore him to normal. His plan fails, but Zook uses his powers to freeze the meteor. J'onn is then able to return to his super-powered self and apprehend Sandez.
