infinity ultron from "what if" season 1.
mcu thanos with all infinity stones.

ultron wants thanos dead, thanos wants ultron dead. who wins?

Probably Ultron

Pretty sure what if Ultron already killed Thanos

he killed an alternate and unprepared thanos, who also didn't have all the stones.

in this fight they are both prepared, both looking to kill each other, and both already have a complete set of infinity stones.

Ultron wins. Way better screen feats.

Thanos should be above Ultron then.

Ultron's feats are hilariously better than anything Thanos showed with the stones. Like full on galaxy busting DBZ fights across time and space type shit.

Thanos is a dude with a powerful glove but he's still physically basically the same, which is a key difference. Even if theoretically their power source is identical Thanos is using a glove to channel the energy, Ultron has perfectly bonded with it.

Ultron would stomp IMO. Not only are his feats much greater in scope, but he was actually channeling the power of the stones through his own form, allowing him to use their abilities across different realities and effectively bypassing their main weakness as a result. This was even addressed directly by What If head writer, A.C. Bradley, in response to fan complaints about the perceived inconsistency with the stones working outside of their own universe:

"Happy Monday! Just a reminder that Ultron is using the Infinity Stones to power himself (same universe being). Also he's legit punching across multiverses turning them into one messy universe soup. #WhatIf #WhatifMarvel #WeDidOurHW #YouAreAllAmazing"

To me, that shows a much greater understanding of the power of the stones than Thanos ever did. What's more, Thanos had all but one stone, IIRC, when What If Ultron cut him in half. And I doubt simply having the final one gave him some huge durability buff, so there's already precedence for Ultron straight-up one-shotting Thanos, whereas the reverse isn't true.

the sets of stones that thanos and ultron had were both still of EXTERNAL control. ultron's were just bolted to his chest armor, instead of a gauntlet. and ultron wasn't punching across "multiverses" during his fight with uatu (especially when there's only one multiverse in the mcu). they were punching across individual realities and (at most) inadvertently causing them to branch.

i agree that infinity ultron has the better feats, but i think that just boils down to a few different things- first their mental capacities. while thanos was extremely powerful and possessed a highly advanced mind, he was still mortal. but ultron's mind was being ran by the mind stone's ai, so it makes sense that he would be able to "process" his omnipotence much faster than someone with a mortal mind (who can do advanced math quicker, you or a quantum computer?) there's also the fact that ultron had the stones much longer than thanos, which gave him even more time to acclimate to their power. so why he didn't just destroy universes with a snap, instead of doing it planet by planet, is odd. i get that it might not be as "satisfying" or whatever, but it is a lot more efficient.

also their overall goals with the stones were completely different. ultron wanted to destroy ALL life in the multiverse through any means necessary. thanos only wanted to destroy half the population of ONE universe at random, then destroy the stones outright. nothing more.

but in this battle they both go in with all the stones, and they are both out for the kill immediately.

Except, if it was external, Ultron would have been powerless the moment he left his native universe, which he wasn't. We can debate the intent and meaning of AC Bradley's statement (which I directly quoted) and the rest all we want, but all of that is ultimately irrelevant. Based on actual screen feats, Ultron has better offense and defense. Ultron's onscreen feats > speculating what Thanos might be capable of with a different mindset. You're free to disagree, but I'm going with the character who has the actual feats on their side.

and the infinity stones only being functional in their native universe is a comics only thing. that rule never existed for the mcu infinity stones in the first place. "what if" just cemented the fact that they CAN be used in other universes, and not just by ultron- strange supreme, killmonger, captain carter, and kahhori did it too. tbh bradley obviously doesn't know what he's talking about. literally no part of his statement makes sense on any level, and is virtually unusable as evidence.

i think a different mindset WOULD matter for thanos here. when he had the stones before, he only had ONE goal- killing half the universe's population. that's it. but here he has a different goal- killing ultron.

Well put

Also MCU Thanos would have blocked that mind blast from What if Ultron.

Thanos knows the snap, Ultron doesn't. Fights starts , Someone snaps , Fight ends.

Who cares about the silly 'what if's'.

Ultron's smarter, thinks faster, reacts faster and far more inventive with the stones. He'd win.

Only using season 1....Ultron wins.

I change my answer to Thanos now. to be fair, that also took place inside the fifth dimension. the watchers are clearly a lot more powerful there.

in the normal multiverse, infinity ultron stomped a watcher solidly. in the fifth dimension, the watchers can stand there and tank infinity ultron's blast, then just walk over and explode him.

He'd win. thanos was actually pretty inventive with the stones, but i don't think that's a good way to compare them anyway. they each had two completely different goals, which means two completely different ways of using the stones.

Thanos used the stones like a fool a lot of the time and this is a fight to the death, not turning farts into butterflies.

Fair enough then.

Nah, those Watchers were powerful enough to erase every version of their opposing team from The Multiverse, that's like way more power than The Infinity Stones ever showed.

No one has addressed that Thanos basically just uses the Stones like a big weapon, a glove he can do cool shit with.

Ultron fused with them.

Thanos with the gauntlet is still just Thanos physically, they don't amp his body.

With Ultron they do.

Thanos is a massive glass cannon and is also far slower and physically inferior, even if in theory they can both have the same powers.

that has been addressed.

and where are people getting that ultron fused with the stones? tchalla was able to snatch a stone from his armor, and it took ultron a while to even notice that it was gone.

Thanos is pretty inventive with the stones just that he wasn't going for the kill even against strange. When he did , half the people in the universe disappeared, didn't matter how powerful you were.

Was he really that fast though? Black widow and friends were all getting shots in.

^ That's a point that Thanos will just snap. That's all he does when he has all the stones.

But then Ultron did beat Thanos to the draw before he became Infinity Ultron, so there is that.

I'm pretty sure Ultron never met MCU Thanos.
All the What if Thanos' were sh*ts

Well as far as comparable foes go I think his Universe's Thanos collecting Infinity Stones would be a decent one.

Means nothing.

He could have done that by any means.
Spiderman had the gauntlet at one point, and we know how he got it. Hulk too. Tony too.

Even if we assume he got it the same way they are still not the same person meaning feats can't be transferred or shared.

We both agree Thanos wins this, I fail to see what point you're driving at here.

I mean that's almost like saying Endgame Thanos is not the same person as IW Thanos. Ergo we can't use feats of both Endgame and IW for Thanos, only one or the other.

But we don't do that, because we realise they have the same history (up to GOTG1) and the same physiology.

As far as I can tell that What If episode only effected what happened on Earth up to the point where Ultron met Thanos. It shouldn't have have made any major changes to Thanos's physiology or his combat skills.

Otherwise we will have to compare the ability of their Infinity Stones separately as well as they are also from difference Universes.

But my main reasoning was comparing how they fair against like for like characters is always a valid point at least. Hence I didn't use it to say that's exactly what would happen.

FYI I didn't agree Thanos wins (definitely in question if we count Infinity Ultron slicing his Universe Thanos in a second). I just admitted it's a good point that Thanos will just snap. So Ultron would have to kill him faster than he snaps.

I'm sure you're not lying, you just missed this; If Ultron acquired Vision's body and was still on earth it means the Avengers lost, Ultron took over Earth, which means , Tony and co didn't fight off Thanos, Thor too. Check what if widow's universe.
So again not the same,
You're notorious for interchanging What if character's feats with MCU. Stop it brah.

That would also mean Party Thor is = Thor 1
MCU Thor is capable of launching CM to another Country with a hit with Mjonir .

Amazing that someone can go into this thread and say "What is Ultron's defense against the snap?"without coming to the much more reasonable conclusion of "What is Thanos' defense against anything Ultron can do"? Ultron's head beam will cut Thanos in half far quicker than Thanos' fat ass can snap his fingers and if you think Thanos is tanking that from a full-powered Infinity Ultron when using the full might of the stones once crippled and badly wounded him from its backlash you're delusional.

And what makes anyone think the snap would even work on him? Name a single character half as powerful Thanos has killed with it. Infinity Ultron overpowered and tanked the Watcher, who per Strange Supreme has the cosmic power to stop and reverse the collapsing timeline he created.

Speaking of Watcher and Strange Supreme those characters would also roll Thanos with the Infinity Gauntlet pretty easily.

Infinity Ultron stomps.

The snap was also random, iirc. Thanos never used it offensively at a target.

MCU Thanos should be able to withstand MCU Vision's Mind Stone blast. However, in What If...?, a single blast from the Mind Stone sliced Thanos in half. This clearly demonstrates a significant difference in power levels between the two portrayals.

Infinity Ultron overpowered and tanked the Watcher, who per Strange Supreme has the cosmic power to stop and reverse the collapsing timeline he created. the stones only wounded thanos when he used them in a universal capacity. when he used the stones in a more localized way, he suffered no feedback at all. so i doubt that will be a problem here, since ultron is his only target. although endgame thanos seemed absolutely confident that he could "shred the universe down to its last atom" and "build a new one in its place" without dying, so who knows.

i don't know how much merit i'd put into a desperate strange supreme thinking that uatu could save his universe, when even strange himself (who became more powerful than uatu) was unable to do it.

also i'm not sure where people are getting this notion that ultron will "speedblitz thanos ftw" or whatever, when ultron himself was getting blitzed by characters like tchalla, captain carter, and black widow.

but gauntlet snaps can still be used in a more localized way against specific targets. that's what tony did when he snapped away thanos and his army.

What Tony did doesn't equal what Thanos did.

When Thor was carving his chest open, he didn't get snapped away.

because his one and only goal with the stones was killing half the universe in a randomized manner- "but at random. dispassionate. fair to the rich and poor alike".

obviously thanos could have included an "oh and also erase every single avenger too!" clause into his snap, but he chose to keep it random like he intended from the start. not even an axe in the chest could change his resolve.

When he used a single stone in a more localized way he didn't harm himself. No one to my recollection has harmed themselves while using a single stone.

Thanos has no durability feats to imply he is tanking a hit from a casual galaxy buster.



Based on what was Strange more powerful than Uatu? Certainly not Strange's own words which indicate the opposite. Strange is in the same realm of power as Uatu and Infinity Ultron but he's the floor of that tier, the lowest.



First of all, that was Killmonger you racist.

Second of all every character but Strange was amped by Strange's enchantment on their bodies to enable them to fight Ultron.

Third of all, there is literally no reason to view Thanos as faster than any of those characters. It's not that Ultron is so fast he can speedblitz like crazy. It's that Thanos isn't very fast at all and has nothing indicating he can avoid one of Ultron's many casual planet vaporizing attacks.

okay. and infinity ultron got sniped by a normal arrow, and also had his arm smashed off by mjollnir. so it's not like he's impervious to harm, even with the stones.

and season 3 strange supreme is basically god ("the" god) within his universe. literally all powerful.

strange's protection spell did just that- protected the others from ultron's attacks. it did not amp their physical abilities like speed and strength. that was all them.

that's fine. all i'm saying is that infinity ultron wasn't depicted as this speedster who will just immediately blitz thanos or whatever. not when he was getting overwhelmed by the speed and agility of a couple enhanced humans.

Sorry, I got the thread wrong - I thought this was Ultron with only the Mind Stone against Thanos.

Since Ultron has all the Infinity Stones here, the only way Thanos wins is if he snaps immediately (assuming he knows who he’s dealing with). Otherwise, Ultron dominates.

Where's this guy getting that Ultron is this speedster that's so fast. Just because he hit a what if Thanos' that didn't even engage him?
Infact at one point he couldn't even hit a single one of
the guardians for an extended period of time ,that he had to use the time stone to slow them down.

Ultron is not hard to hit even by human level speed lol.

Thor's hammer took his arm off, what's protecting him from a snap?

If the stones are the same, The mind blast isn't cutting MCU Thanos in half. It didn't cut Ultron in half in AOU or Vision in infinity war. MCU Thanos is far more durable than both.

Party Thor's history is very different given he didn't grow up with an adopted brother - Loki.

We can literally see the difference in physiology of his Loki, who again has had his childhood changed.

That said, I see no reason why MCU Thor and CM wouldn't be able to smack each other around the Earth. Even though I agree that Party Thor definitely seems > MCU Thor. Not sure about MCU Stormbreaker Thor though (but again this is going off topic).

But in principle my point is correct. God Loki from his solo series clearly ends up being Massively more powerful than MCU main Loki. However up until Avengers1 they were exactly the same. Hence why when the series started we realise MCU Loki was able to use TK and energy blasts which we didn't know prior to the series.

I said "Up to the point where Ultron met Thanos". Ergo up until IW. So not sure why you're bringing up Tony & Co. fighting Thanos.

Yes I am because they're "What If's". They are part of the MCU Multiverse. There's a clear correlation there, even if things diverge very differently after a certain choice.

On the other extreme if you're going to treat them as completely different beings with no relation to each other at all, then you will have to answer if you see IW and Endgame Thanos completely different also, and count their feats as completely separate (Endgame Thanos did not go through the IW war events, and his timeline has clearly diverged from the MCU 616 Thanos at the point of the start of GOTG1).

One thing is certain: MCU characters don't share the feats of "What If...?" characters, as they clearly operate at different power levels (e.g., Thor).
MCU Thanos is significantly more durable than "What If...?" Thanos, as he isn't going to get cut in half by the Mind Stone.

IMO, snapping is the only way MCU Thanos wins. However, I could be wrong, as some of you are making good points.
