I wouldn’t immediately undo past writer’s work, that’s gay when they do it, like Cates with Hulk, but the plan is correcting things across the books.
Superman Ongoing: Establish early that Superfamily isn’t all in Metropolis and Supes is back to “part-timer” status in the League. Quietly get rid of Supercorp, Lois with powers, re-introduce “master criminal” Lex and cool off the CEO yuppie who has a Superman complex. Get every character’s “what’s canon and what’s not” in-place and divide characters where necessary, like where the N52 version is an evolution or a new character. Get the versions of characters I would use fully in-place for an overarching storyline that dives into the human/kryptonian divide.
Action Comics meanwhile is divided into three parts.
Superman: Silver Age, we return to what the reader thinks is the Silver Age but is actually evolved Earth Prime and this Superman is Superboy-Prime, all grown up after Dark Metal. It seems unconnected but the theme of fate and inevitability is addressed, for example, he’s got issues with starting a relationship with his universe’s Lois because he’s seen it millions of times.
Lost Son of Krypton: The Phantom Zone has been quiet lately, even stable. Inside the prisoners are in perpetual battle, all united against two foes, eager to kill the only accidental prisoner of the Zone. Jon Kent, one of two halves (kid Jon is red, teen is blue) and accidentally dumped in there through a gap between worlds. His only protector is the other prisoner with an S on his chest, the Eradicator (original Reign one) who’s fighting his programming to protect the “half-breed.” One Jon was imprisoned with a doppelgänger who had his father’s face and hurt him while time passed, the other Jon is imprisoned with a doppelgänger who has his father’s face and won’t let anyone hurt him while time isn’t passing.
They find a literal door out (Uncle Mxy) and go on cosmic adventures trying to get home. Terminator homage obviously but ties into the “fixing” of the Superfamily idea.
Third story in each issue is a one-shot for a character in the series, getting them back where I want them. Like Natasha Irons joining the Titans and John Henry becoming the only Steel in the Superfamily. Lexcorp/Supercorp is absorbed by Steelworks. Others include Jimmy dating Powergirl to Clark’s horror, Lois choosing humanity because being in Clark’s shoes and seeing the world as he does is pretty awful.
Key themes, include the universe rewarding good people, Jor-El and Lara trusting in strangers for their son and the “worst” member of the Superfamily locking in to protect Jon, alongside Mxy. Another is Clark being old school in his justice and not caring about the consequences, no matter the Superman, whether it’s Clark, Prime, Eradicator, Steel, Conner and both Jons, they’re gonna do the right thing, fuck the consequences. The final one is the right thing always being an option, no matter what. Prime, Eradicator, Metallo, even Zod all show they can be better.
Payoffs include.
-Jon and Eradicator meet a Golden Age version of Clark during their hijinks in the cosmic fallout of Bendis’ nonsense (there’s literal cosmic damage) and both are awed, Eradicator moreso.
-The three core eras of Superman are respected and restored, not through undoing plots but evolving characters. By the end, there is a Golden Age Superman in the form of Eradicator, redeemed and forgiven by Clark. He joins a reformed Outlaws with Red Hood and Artemis as the “Dark Superman.” There is a Silver Age Superman with Prime who is now the “big gun” like Kal-L was during the Crisis and he uses a wish from Mxy, that could’ve saved his Laurie Lemaris, to restore Earth 2 and he formally apologizes to Kara. Finally, our main guy is clearly defined as the best of both worlds, any of the post-crisis “replacements” for the Man of Steel origin are retconned and Clark’s manhood is restored by letting him be a little macho and smug again, he’s the best, he’s allowed to act like it.
-Superfamily pruned, Power Girl goes back to Earth 2, Conner replaces the dead Superman of Earth 52, Natasha is gone, the little brats get killed by Hank the Tank, gay Jon isn’t axed suddenly but he ceases to exist so his younger self can be a whole being once again, Steel is dead but prevents a nuclear holocaust and reaffirms “man beats machine” by beating a superior foe down with a hammer and dying to save everyone (he gets his own “Death of Superman” fighting Henshaw) and anyone alive is quietly sent off. Conner gets to be N52 Supes, Eradicator is vibing as Golden Age-style Superman, Power Girl is the premier superhero of her restored world, Prime is given a “gift” by Mxy and finds his world has superheroes other than himself and Lois and Clark get their true son back.
-Redundant characters removed, Rebirth/N52 Eradicator is dead, every Brainiac but one is axed, the Phantom Zone villains are reduced to Zod and Faora, Warworld reverts to the rule of a new “Mongul” AKA Doomsday (Mongul and Doomsday are both Hulk expies so I cut the bullshit), Kryptonians are endangered again and everything post-Rebirth is acknowledged as “happened” but it is almost all fixed and where it belongs, in the garbage.
