Since Byrne's Krypton was gradually removed from continuity in the early 00s, I have trouble imagining how the Eradicator fit into the more traditional depictions of Krypton. I imagine Eradicator was primarily a plot device to explain why nobody ever left Krypton, leaving Kal-El as the only survivor. But since the Eradicator apparently wasn't put to use as it was on Byrne's version of Krypton, where does it/he fit in? And did the Eradicator ever create an Antarctic fortress in current continuity?
