Page "Krypton (comics)" Paragraph 42

Beginning with Infinite Crisis, Geoff Johns began laying subtle hints to a new origin for Superman.

" Last Son ", a storyline co-written by Geoff Johns and Superman director Richard Donner, further delves into this version of Krypton which reintroduces General Zod and the Phantom Zone criminals into mainstream continuity.

With art by Adam Kubert, the design of Kryptonian society is distinct yet again from Birthright, incorporating elements of both pre-Crisis on Infinite Earths continuity and Donner's work on the first two Christopher Reeve films, in particular the notion of Krypton's Council threatening Jor-El with harsh punishment were he to make public his predictions of their planet's imminent doom.

Whether this further revision of continuity has an in-universe rationale is as yet unknown, but it may stem from continuity changes wrought by the reality-fracturing conclusion of Infinite Crisis.
