I was happy to note in the final issue of 52 that Rip Hunter was going to check on whether anything in the past of New Earth had changed as a result of Mr. Mind depredations.
Let's hope so. DC's already quickly and subtly put both Black Canary and Wonder Woman in the original JLA.
I can think of a few things that deserve to be fixed or eliminated. At least, 42 of them, in fact; I ask you to supply the remaining ten!
1. Donna Troy. Please, DC, stop trying to be so metatextual with Donna. If there must be a Donna Troy, keep it simple. Hippolyta wanted a sister for Diana, and the gods let her make one; end of subject.
2. Jason Todd. Let's just say Jason, who was older when he was Robin than we remember, survived his brush with 900 numbers, retired from Robinhood, then got ticked and came back when he found out Batman had gotten a new Robin.
3. The Rolling Heads of Ganglords. While you're taking the cosmic whiteout to Jason's past, make sure you dab the scene where Jason brings a duffel bag of severed heads as trophies to a gang meeting. If you want to use him as a "Black Sheep" hero, that's fine, but we don't really need heroes (in the DCU) who kill people and cut off their heads.
4. Hush. You don't really need me to explain that, do you?
5. Aquaman. It occurs to me I may have mentioned this one before. This is about the third reality-altering event in the last few years to provide a perfect opportunity to return Aquaman to a version recognizable to the public, both in appearance, powers, and behavior. You blew it the last couple times; don't blow it again.
6. Lex Luthor. If there's any concrete reason that Luthor's presidency needs to remain in continuity, I can't think of what it might be. Let's go right from CEO Luthor to Project Everyman Luthor to Mad Scientist on the Loose Luthor and leave it at that.
7. Black Lightning. Let's lose "Education Secretary" Pierce, Dead Niece, and Young Adult Daughter Who Sprung Full Grown from the Head of Judd Winick. While you're at it, consider losing the Head of Judd Winick as well.
8. The Joker. I think we could all struggle along just fine without having to remember Last Laugh.
9. Bizarro. Likewise Emperor Joker. Stick with the simple and more traditional "failed clone of Superman" backstory. It's more consistent with his usual portrayals anyway.
10. The Slab. Almost forgot, Last Laugh is what moved the Slab to Antarctica. Either (a) forget about "the Slab" entirely (b) re-place it wherever it originally was.
11. Gorilla Grodd. I have no idea what writer was stupid enough to change Gorilla Grodd into a carnivorous primitive generic monster, but he's already cashed his check, so let's just forget it happened and move on.
12. Catwoman. Most people ignore the absurd, insulting, and out of character idea that the freaking Catwoman was ever a prostitute. Let's just make that official policy, shall we?
13. Knightfall. Really. What would it hurt for this whole thing to have happened on some other earth? We can forget Bane, Azrael, and Shondra Kinsolving in one fell swoop; I find that an irresistible trifecta.
14. Obsidian Age. No one understood it, no one liked it, and it didn't do anything.
15. Millenium Giants. See "14. Obsidian Age".
16. Booster Gold. I think we can all agree that remembering that Booster saved President Ronald Reagan from assassination is no longer in our best interests. Same with his sister, "Goldstar".
17. Extreme Justice. I mean, who's going to argue against that? Dan Vado? The Wonder Twins Fan Club?
18. "Slideways" and "the Kitchen". After all, why waste any time?
19. Black Canary. Let's put "Dinah gets raped and has her throat cut" in the same trash bin as "Dinah dates Ra's Al Ghul and falls in the Lazarus Pit". Then we can all be happy.
20. The Sea Devils. The Sea Devils are not, and have never been, environmental terrorists; the Sea Devils are, as everyone knows, superior beings. Have them be just as they originally were, but hosting an underwater "Josh Bernstein" style adventure series on TV. Because you know they know how to work the camera!
21. Plastic Man. No, not his illegitimate son; Fernus. Send Fernus to the furnace, wrapped in, well, pretty much anything else Joe Kelly's written for DC. This one, by the way, works well with forgetting Emperor Joker (#9), which is what gave us "Scorch".
22. Vibe's death. I mean, can't we just say he got really really sick for a while? Please?
23. The Sword of the Atom. I'll say more on this later. A lot more. But let's just keep "Ray and Jean break up" and jettison the part about the Littles living in the Amazon jungle.
24. Lana Lang. Oh, where to start. Lana is pretty much a one-person generator of Stories That Need to Be Retconned/ Erased by Hypertime / Punched by Superboy / Eaten by Mister Mind. Starboy; Insect Queen; Lana the Manhunter; Conduit. Those are all safely gone, so let's send Mrs. Pete Ross, Vice-President and President Ross, little baby Clark Ross, and Luthorcorp CEO Lang to join them. Lana is most meaningful when she symbolizes the wonderful small-town life that Clark had to give up in order to be Superman.
25. Wonder Woman. Bana-Mighdall, and all that that implies (including Artemis The '90s Extreme Wonder Woman).
26. Green Lantern. At this point, is there any really reason to keep the "Hal Conquers the Universe/ Becomes the Spectre" baggage? Corrigan died and the Spectre created trouble before finding a new host. Pretend Hal got killed by Sinestro or a falling ceiling tile or venereal disease. Or never died at all.
27. Green Arrow. Oh, yeah, and Green Arrow, too. Connor Hawke isn't worth screwing up with Ollie's age/timeline. No, really; he's not. He's just part of the failed '90s experiment of replacing Silver/Bronze Age characters with Iron Age hipsters. It's enough to show that Ollie's a jerk every time he opens his mouth and give him an ex-prostitute for a kid sidekick; he doesn't need an ex-junkie ward, an illegitimate son he intentionally ignored, and Kevin Smith's revivification of Ollie Queen that managed to "rape our childhood" by turning Stanley & His Monster is a typical Alan Moore/Vertigo tale of incestuous child molestation/satanic worship.
28. Red Arrow. Speedy was hooked on cocaine for ONE ISSUE, people, thirty years ago. "Beloved" as that atrocious story is supposed to be, it's crippled the character ever since. Brad Meltzer can force real JLAers to say how wonderful he is every issue, but he'll never be more than the Drug Addict Leaguer as long as that story remains in continuity.
29. Hawk & Dove. Not just the two female ones; the previous versions, too. Vietnam, the Lord of Order & Chaos, Monarch ... face it, folks, everything they touch goes straight to Heck.
30. Matrix Supergirl / Australian Alexander Luthor/ They Stole Luthor's Brain. Sure, it was fun while it lasted, but it seems to already be out of continuity or part of a general consensus of silence.
31. Brainiac. This one's rather a mess, so everyone's left it alone for quite a well. But we could have our cake and eat it, too, I think: Brainiac is a renegade Coluan genius who augmented his intelligence by incorporating AI directly onto his skull, and has lost his humanity (or "coluanity", I guess) as a result. This works with his three main character points: "freaky alien collector", "evil computer", and "ancestor of Brainiac 5".
32. Kyle Rayner. I like Kyle; I have always liked Kyle. He's sexy, fun, clever at using his powers. But he's in the way and his absurd near-deification as Ion is a pig in a dress no matter how they spin it. Kyle; enjoy Earth 8.
33. Leslie Thompkins. I have literally not heard of anyone who approved of "what they did to Leslie Thompkins." If you want her out of the way, let her stay abroad doing missionary work. But let's just say that Spoiler died from her wounds and Leslie wasn't able to save her, despite her best efforts.
34. Captain Marvel. Do we really have to wait until Trials of Shazam is over before we declare it null and void?
35. Nightwing. Okay, it's not really a retcon per se, but I think that "Nightwing" as a brand, is badly damaged (and in many ways, never really flew). Despite the resonance with Kingdom Come/Earth 22 (which I hate), let Dick Grayson become Red Robin. Maybe then writer can write him as Robin Grown Up rather than a confused Marvel-lite member of the Legion of Super-Emos.
36. The New Guardians. I think I'd pay to forget the New Guardians.
37. Primal Force. I'm one of the few people who actually bought and liked Primal Force, the doomed "Shadowpact" of its day. But that time is over now.
38. Hawkman. Hm. That's hard to narrow down, isn't it? Pure confusion eliminates most unpleasantness from Hawkman's backstories already. But Golden Eagle's betrayal of Hawkman was a big waste of the character (and, like everything Hawkman, very confusing). Scratch that.
39. Firestorm. I'm pretty sure there's only one thing I'd change about the current Firestorm: the cancellation of his series.
40. Dr. Thirteen. I don't want a world without Dr. Thirteen in it, and I don't think the Phantom Stranger would either. Making me unhappy is one thing ... but you really want to tick off the Phantom Stranger?
41. The Penguin. Can we ignore all the "Penguin as punching bag" stories? For pete's sake, the Penguin was Burgess Meredith, not Peter Lorre. I want to see him start to kick some tailfeathers.
42. Two-Face. As long as we're forgetting the Hush thing, let's forget Vigilante Dent and the whole clumsy "I'll rip my face open" thing.
