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?

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.

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

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

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.

...Or was that retconned?

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

.
But even if it wasn't retconned, why couldn't warping reality so this isn't possible be an option? Reality Warping by near omnipotents is brokenly OP.

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?

Originally posted by Juntai
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

That's true. I wonder if someone could take away Doomsday adaptive abilities? Someone like Surfer, and then perma kill him afterwards.

Surfer would also need to mindwipe the entire DC Multiverse of the memory of the entity known as Doomsday, including himself

Yeah ok. So you would need to a) kill Doomsday and b) do a multiversal version of what happened when everybody was made to forget that Sentry existed.

Easier if you can do the second step from the White Hot Room (or its DC equivalent - ie multiversal psychic nexus point). But you would obviously need an uber tier psychic.

Yeah, only Goober's Surfer could do that

That whole memory rebirth shit is retarded trash, even by comic standards.

What about the teleport prison Doomsday was already in? Did he evolved out of that or did someone free him?

He was freed by Manchester Black and Task Force X - Steel died doing so.

What i don't understand is he's supposedly overcame physical strength due to his adaptation abilities. Even if Parasite absorbed his power, why didn't he just tank Superman's punches if he was so far above just being physically broken? Does this ability not worked when it's tampered with.

Superman punched him harder than he has previously been punched before -this was due to Superman holding back less than he would with others.

So if in DoS Superman 'killed' him with level 100 punches (for example), and the gang of Kryptonians beat him with level 150 punches, here Superman was using level 200 punches from the start - just using arbitrary numbers.

No i don't. DOS Superman miss trash. So Doonsday isn't above physically being killed is what I'm reading.

Since we know absorption works, I wonder if Rogue could hold on to him for a while, absorb his essence, and kill him afterwards, if that would work.

Originally posted by carver9

Wouldn't it only make Doomsday stronger? As, even in the recent Superman comic, it specifically mentions Parasite shouldn't kill him by absorbing. Because it only makes him stronger

Originally posted by carver9

He adapted on the fly to Waverider and the MotherBox....holding him 'for a while' wouldn't be that easy, even assuming Rogue can hold on for that long.

And then, that doesn't kill him permanently

This is a different absorption though. She's absorbing everything that makes Doomsday Doomsday. This isnt like Parasite.

Remember how Doomsday just tears apart Parasite.
And Parasite says Doomsday's power is basically bottomless, so I would think it's really hard to hold long enough to completely absorb Doomsday's energy

What about Stasis?

Originally posted by carver9

She can hold on for that long? Doomsday is bottomless, as said by Parasite. He also gets stronger the angrier he gets, and getting drained by Rogue would make him incredibly angry.

Not to mention she's also now absorbing the countless memories of being killed, especially as a baby.

And then, after all that.....Superman remembers the time he got killed by Doomsday, and the memory brings him back to life.

Is Doomsday resisting? That changes things

I assume it was the version in OP I.e. all surrounded by lava etc.

Nothing mentions him resisting, though. It's just asking if he could be killed.

Originally posted by carver9

This thread isn't about whether Doomsday can be killed (he clearly can), but whether he can be killed permanently (i.e., remain dead for eternity). I don't think Doomsday's lack of resistance to being killed is relevant here.

Well he looks pretty angry and spoiling for a fight is what I'm saying. Like he's not just lying there passively waiting for someone to phuck him up.

What if instead of power absorption we try power bestowal.

Maybe somebody like Zatanna could transfer Forget-Me-Not's powers into Doomsday. And then kill him.

I was going to increase Matter Eater Lad to giant proportions then eat Doomsday, but that also works

This is the answer I was looking for H1.

Galan, do you think Doomsday can survive Beerus existence erasure?

Originally posted by Smurph

Maybe somebody like Zatanna could transfer Forget-Me-Not's powers into Doomsday. And then kill him. I'm unfamiliar with FMN, but if his powerset were transferred into DD, would everyone who has ever seen/heard about him completely forget that he ever existed(even those in other timelines/dimensions)?

If so, that seems like a good route to go.

Originally posted by carver9
Galan, do you think Doomsday can survive Beerus existence erasure? No, his body would likely be nullified(ala Zamasu.)

...But that still wouldn't be a permanent defeat in DD's case.

So with FMN, he doesn't really go into the field (being forgotten). So the actual opportunities for him to meet people in other dimensions/timelines is nonexistent. That said, his power is to be forgotten, so I'd assume (with no proof) that it works everywhere, just like Logan is stabby everywhere.

Sounds like a mutant circuit is needed with FMN somehow involved without everyone forgetting he's part of the team.

Nullification, Pym Particles, WB Hulk putting those knuckles on him, Superman going solar dipping and going all out on him.

I'm sure those things will kill DD, but that's not the point of the thread. It's killing him and preventing him from 'respawning'.

If so, that seems like a good route to go. Like DS said: https://imgur.com/jHoy2KZ

His power is that he simply "slides" out of memories. And it's automatic, doesn't matter if it's an uber psychic etc.

It would make Doomsday incredibly deadly while he was alive. But I think it would guarantee that once he's gone, he's forgotten.

Maybe I'm wrong and he IS a field team member,, EVERYONE does indeed forget him.....

I know most (but not all) tech also has an issue registering FMN... But if that powerset were transferred into Doomsday, what would happen to all of the preexisting records of him?

-Video footage of his rampages
-Newspaper reports/pictures
-Generic internet articles
-The files from STAR Labs
-The Book of Oa
-Henshaw's databanks
-Motherboxes
-The LoSH archives
-etc.

Would all of that information just go away as well, or could someone(with no memory of DD) conceivably stumble upon those records, and poof, they re-remember Doomsday and become a possible host?

Tbh, I didn't even think about that sort of thing until now. Since he can regenerate from memory, even multiversal mind-wipes might not be enough to end DD permanently. You'd have to erase him from the history books as well.

Also I'm not sure how someone then kills a Doomsday who is now rampaging without anyone knowing they're even in a fight.

Using Smurph's tactic: Maybe the best thing to do would be to physically 'kill' DD first, then have Zatanna transfer FMN's powerset into DD's corpse the instant before they completely erase him(via entropy-dump or w/e)..? Otherwise, yeah, it just makes initially 'killing' him that much harder.

And even if that worked successfully, you still have to think about the preexisting records of Doomsday's existence that I mentioned above. What happens to all of that info? Memory-regen is ridiculously hard to get around.

Ya it's a good point.

You could make a good story out of Planetary travelling from universe to universe using Drummer to systematically eliminate traces of Doomsday.

You'd have to expand on Drum's powers a bit tho.

A wish of the Miracle Machine, maybe?

That would work. Using Drummer would also necessitate Planetary wiping their own memories

Which they did before didn't they?

Or maybe that was just Elijah

Yeah it was just Snow. Iirc the team all knew.

On the time manipulation note...

If someone regressed Doomsday to a point in time before Bertron started experimenting on him(similar to what Thanos did to Runner here), would that effectively negate any possibility of DD regenerating as he previously was, because he isn't technically dead... Or would memory-regen still be applicable, because the baby that would eventually evolve into Doomsday =/= Doomsday as we know him now..?

Zoom could go back in time and kill Bertron as a baby. I mean Waverider might not be bloodthirsty enough to consider it a viable tactic but Zoom damn sure is.

Probably a good case to make both ways, DC can't make up their mind on him. That guy from Cadmus talked about him having no emotion but rage or thought about anything but death and destruction in DOS, then in Hunter Prey they said he saw Supes as Bertron and was terrified of him because he remembered the cycle of reincarnation, then when Brainiac took his body Supes said he was weaker because unlike Doomsday he felt fear... who the Hell even knows at this point lol

Does Zoom then off himself? Or do his own memories erase?

Kill himself

He will remember DD as the pure hearted soul that he was, if he returns he will then be a philantrope.
