Justice League of America, Vol. 1 – Issue 188

The Justice League, in their transformed bodies, arrive at the scene of the bank robbery just as the fake Leaguers leave. A short battle ensues where the fakes are revealed to be duplicating the heroes’ powers by machinery implanted in their costume. Having damaged Proteus’s machine that transformed them, Flash finds Zatanna as a street derelict and convinces her to change back, restoring her memory of the conversation they had in the JLA satellite.
