Edge's plan to resurrect Krypton on Earth echoes the efforts of General Zod in Man of Steel (2013) and the Worldkillers in season 3 of Supergirl (2015).
In the comics, the Eradicator is one of the Supermen that took over for Superman when he died at the hands of Doomsday in one of the most famous Superman comic lines. And in it, he is the Kryptonian stand-in for Superman until the original Superman's return in the story.
