Conceivable ways to beat (or kill) Doomsday, permanently?

I'm talking about the most recent iteration of Doomsday(the one who physically busted out of Hell):
https://ibb.co/82pS4xp

Seems like DC has gone out of their way to emphasize DD's absolute immortality/adaption... But are there any loopholes that come to mind which might be able to subvert this, and kill him for good?

And if that isn't a possibility, are there any ways to permanently stop DD without killing him?

You can go nuts with theories here(even if they're OOC for the characters involved)... I'm just curious.

*Note*
I'm looking for more creative/out-of-the-box tactics. Not necessarily things like: "Mxy vapes continuity, ftw!!"

Time manipulation? Reverse Doomsday back to when it was originally created?

Or trap it in a time loop always rewinding it back to the point before it developed its adaptation?

I would try:

Matter manipulation - change him into other elements. Maybe with magic.
Time manipulation - either timestop/speed steal, or reversing time like Glorificus said
A variation of the Zeno Room from Reed, with a slight modification that it's powered by an (inefficient) sound powered mechanism. So every time Doomsday roars, about....5%? 10? Of the sound energy gets converted into power to fuel the room. It's inefficient because I don't want him to overload it, not that he would think to do so.
On a similar note, a variation of the JLA transporter trick where he was split over 4 of them. He never evolved out of it iirc, but was freed by the Suicide Squad to take on Doomsday.

Edit: or I just get a second Doomsday, but from one evolution further on (so using time shenanigans). Hopefully they fight each other to be the dominant lifeform as is their nature.

Time manipulation is the best I could think of as well. Something akin to what Thanos /w/ the time gem did to Runner: ie. regress him back into a baby or whatever and either kill him, or allow his original self to just live out his life in peace.

I know it's a stretch, but the only thing that makes me somewhat question how viable time manipulation would be is the fact that DD was shown encountering/fighting Superman Prime 1M... In an era where Hourman had the Worlogog and was not afraid to use it. This could imply that at some point DD develops immunity to temporal shenanigans, but how he gets to that level is the question. I do think it would work against this version of DD, though, given that he has yet to face that kind of power directly.

As for the transporter tactic the JLA used: DD couldn't adapt because he never had the opportunity to form a cohesive thought -- he was kept in a perpetual state of flux, and effectively trapped in that moment... But I wonder if he adapted beyond it after being set free..? mmm

Powerful enough reality manipulation should do the trick.

Or... alternatively, strong enough Empathy/mind control.

Something that can overwrite or rewrite its behaviors and impulses/urges.

If you give Doomsday sufficient Empathy and personality changes, you could make it become a pacifist and psychologically repulsed from violence and fighting.

An opponent cannot win if it CHOOSES willingly to not fight and give up... so something that can make it change behavior and mentality is key.

Perhaps Psycho Pirate and his empathy? Or alternatively going down the psychology route, Ebony Maw or TAO with sufficient persuasiveness?

For example, say TAO or Ebony Maw somehow manages to convince Doomsday that it is the ultimate life form and that it already has reached its zenith, and that no living organism is as strong as it... which just leaves it as its only challenge remaining - can it prove strong enough to defeat itself? And if they can convince Doomsday to see ITSELF as the ultimate foe to defeat, since nothing else is as strong, perhaps they can convince it to focus all its energy and evolutions to finding ways to kill (conquer) itself?

Absorption just worked on him. How can you evolve past this and is there proof that he could?

This is my opinion too. I mean, they can literally rewrite reality to be whatever they want. They can just make it so Doomsday's adaptability doesn't work and kill him.

...Or was that retconned?

Do we count future version here, his Time Trapper version for example?

His Time Trapper incarnation is from eons in the future and WAY too haxx to quantify.

Doesn't DD still have that wacky, Freddy Krueger-esque ability, where he can regenerate from just the memory of himself? ie. Doomsday's current body is "perma-killed", but some random person on some random planet still remembers him, and *poof*, they become his next host.

.

I thought just rewriting reality was a bit too simplistic (Mxy vaping continuity).

What if we shrunk Doomsday, THEN had power leechers hit him whilst he's tranqued with Black Mercy (which I loved btw)?

So, he's first tranqued, then shrunk, then leeched. It wears off, he wakes up in a perfectly scaled miniature world, where he can rampage away without ever realising he's shrunk. Nothing to kill him, so nothing to trigger his evolution. I don't think he ever evolved the ability to travel between worlds, so no danger of him getting off (miniature) planet

has he faced an uber psi? i wonder if he could be trapped in a powerful enough illusion. maybe something like he and superman fight to reach each other to end things but they never really get there? or some fun variation. i thought of speedsteal but i have a feeling that wouldn't work for long--might freeze him for a while but he'd adapt to it quickly methinks.

i remember a time when you and i talked dd up and people thought we were crazy and over exaggerating what he could be. glad we were right. again. 😂

Manchester Black mind whammied him pretty long-term ( as in, it held for a long time as he kept fighting Imperiex Probes even though Chester wasn't there).

Brainiac tried controlling him but it was beginning to wear off.

Martian Manhunter tried it with Doomsday Rex and he just ....got hit with fire breath lol.

Black Mercy tranqs were working on him (but it seemed to be less psi, more pheromone type control).

At full potential, Elixir should be able to hack Doomsday's adaptive evolution. Build a back door blind spot that will emerge over iterations of adaptation and which would trigger permanent system collapse. An Achilles heel inside the mechanism for Doomsday's immortality.

Make it something weird like singing at the exact frequency.

The more I think about it, the more it seems like trying to perma-kill DD isn't the best way to defeat him. Eternal imprisonment, or some sort of esoteric regression, seems like the most efficient way to go.

Because even if you completely erase/kill DD's physical body, then you have to worry about him regenerating from the memories of others... Which would then entail preforming universal(and higher-dimensional) mind-wipes, across a slew of timelines, in order to ensure that he stays gone forever.

And even IF you found a telepath capable of the above, they'd also have to mind-wipe (or kill) themself afterward, for good measure. /shrug

...But I guess if DD never realizes he's trapped in the first place, then yeah, there's no real danger of him ever getting out(akin to the Chaos King's ending.)

Any proof that Doomsday can survive anti matter?

again, if he can regenerate from memory, then it doesn't matter.

Again I emphasize permanent defeat.

Don't see anyone killing DD permanently... but then again it's comics so it's damn near impossible to kill ANYONE (of note) permanently. His adaptive ability is just a handwaving manifestation of the real world fact that the writers will eventually resurrect everybody so it's one of the few abilities we can count on being effectively limitless. No one can manage to kill Redskull permanently, what the f*ck hope would anyone have of doing it to Doomsday lol
