wow i didnt think there was an issue with thse ones... i mean its powergirls origin?? why are people dissagreeing with that?
It's more than her origin. This story is what laid the groundwork for the chaotic and disparate "origins" that she has had for the last 20-odd years or so. From Kryptonian cousin, to Atlantean princess who only thought she was Kryptonian, and everything in-between and after.
In this story, the idea that her Kryptonian origin could have just been a computer-induced virtual fantasy is introduced. To me this is non-canonical like the World's Finest issue that claims the super-sons were a computer simulation; and like Supergirl's wedding and the other post-crisis, pre-Byrne nether-zone tales.
It also introduces the whole "malicious technology from an evil Krypton trying to take over a Kryptonian" thing. Another concept that was used throughout the Iron Age and still rears its ugly head from time to time.
