He then flies to his new base of operations in the Source Wall where he had been torturing Mister Mxyzptlk into helping him recreate Earth Prime. It is revealed that Superman-Prime is 19 years old. According to Mxyzptlk, his growth is the temporary side effect of his cells absorbing vast Oan energy from his last "encounter". Mxyzptlk escapes with the help of another prisoner, Annataz Arataz, an alternate version of Zatanna from Earth-3. Annataz is killed when Superman-Prime grows angry and gives up on using magic to achieve his goals.
