* GoodCounterpart: Lex Luthor of the Pocket Universe, being the heroic counterpart of his mainstream DC Universe version.

* AlternateUniverse: The Pocket Universe, which came into existence when the Time Trapper took a sliver of the mainstream DC Universe from the distant past and crafted it into his own private universe, eliminating all life-giving worlds except two: Krypton and Earth. Its Krypton was crafted into one resembling the Silver Age[=/=]Bronze Age Pre-Crisis Earth-1 version, while its Earth resembled that of Earth-1, minus all its heroes save for Superboy.

* GreenRocks: Superman made use of the two specific isotopes of Kryptonite against the Phantom Zone criminals -- the Gold Kryptonite to strip them of their powers, and the Green Kryptonite to kill them. They do not work on Superman due to the difference of radiation emissions between the universes' isotopes.

In the story, Superman encounters a young female wearing a variation of his outfit that calls herself Supergirl, claiming that her powers came from ComicBook/LexLuthor. A brief fight occurs due to a misunderstanding between the two, but after Superman and Supergirl straighten things out, it is revealed that she came from the [[AlternateUniverse Pocket Universe]] that ComicBook/{{Superboy}} of the ComicBook/{{Legion of Super-Heroes}} had come from. With the both of them now transported into that universe, Superman learns from its Lex Luthor the history of its Earth since Superboy had departed: that Lex had accidentally let loose the Phantom Zone criminals that have terrorized and devastated the entire planet, leaving only those who are within Lex's Smallville citadel its only survivors. The Phantom Zone criminals eventually killed the last surviving people of that Earth and reduced Supergirl to a protoplasmic puddle, where it is revealed that she was actually an artificial lifeform created by Lex Luthor to replace the deceased Lana Lang. Realizing that he was the only superhero left in the Pocket Universe, Superman rounded up the Phantom Zone criminals, stripped them of their powers, and subjected them to lethal radiation from that world's Green Kryptonite.

* DirtyCoward: The Phantom Zone criminals, when faced with death by Green Kryptonite radiation. General Zod is ready to throw Quex-Ul under the bus to save his own skin, and Zaora is left pathetically begging for her life, promising to show pleasures to Superman for her freedom.
