Can the Flash use his powers and super speed outside the DC universe?

If the DC speedsters draw their powers from the Speed Force, and the Speed Force exists in the DC universe only, does it mean that the Speed Force is their only source of speed, and they are reliant on the speed force to even run fast, let alone other abilities such as using the infinite mass punch and time travelling?

As an example, a friend of mine was comparing Quicksilver of Marvel to Flash of DC (mainly Barry Allen, but anyone who uses the Speed Force is applicable), and he said that outside the DC universe, say in the Marvel Universe, Flash would be powerless with the non-existence of the Speed Force, and he wouldn’t even be able to run fast.

Is this true?

    I have a strong suspicion this isn't answerable, it's close but not quite "Gorilla vs. Shark". But The Flash himself doesn't exist outside the DC universe, so of course he can't use his powers?

    @MikeEdenfield Marvel universe say, like in a crossover, where Flash goes to marvel universe to fight, say, Quicksilver. Then what?

    in that case, the marvel universe becomes part of the DC universe... you should probably rephrase your question to specify that you're asking about marvel/dc crossover, and also be careful of Gorilla vs. Shark

    Asking how a DC character would theoretically function in the Marvel universe is meaningless - it's like asking whether the Borg can assimilate a Hutt or whether a member of the Great Race of Yith can conquer the Elder Wand. Commented May 1, 2019 at 19:14

The short answer is "he very well might lose his power". The longer answer requires understanding how DC structures their comic book stories, so buckle up.

The terminology is a bit confusing here, because Marvel and DC don't have "universes", they have "multi-verses". Since you're specifically asking about "in another universe", it's important to make that distinction.

The "DC Universe" is not one universe. It's actually a multi-verse, consisting of many different universe with their own separate histories, characters, etc. The Flash from one DC universe (e.g. "Earth One" or "New Earth", depending on what year is it) can travel to a different DC universe within the Multiverse with no problem. In fact, Flash is somewhat unique in this regard, as the Speed Force is often cited as the key element of the multiverse that ties such things together. Thus, if you're using universe in the sense of "the entirety of space and time in a particular physical reality", then Flash can go to all kinds of universes, and be just fine.

However, DC also has the concept of multiple multiverses, which is usually called "The omniverse". The Marvel multiverse exists within this omniverse, and on very rare occasions, DC characters can go there as well. However, there's some things to keep in mind here:

  • Marvel's multiverse consists of a lot of universes, each with their own rules. You can't necessarily apply what happens in one universe to the others.
  • The Marvel multiverse is now officially "part of" the DC omniverse. By definition, anywhere a DC character ends up becomes part of the DC omniverse. Thus, in the sense that the average person uses the word "universe" to mean "everything that could ever possibly exist", it's not really correct to say that Flash can ever be outside of the DC universe.
  • Most Importantly, these crossovers are almost always non-canon -- as far as the primary history of DC's characters is concerned, they never happened. Thus, you have to be very careful not to make any generalization about them; the next author to do a Marvel/DC crossover could very well ignore any previous crossover stories, and make up her own rules.

Having said all that, one of the most popular DC/Marvel crossover events was the "Avengers/JLA" crossover from 2003. In that series, the JLA from DC's main New Earth were pitted against the Avengers from Marvel's main Earth-616 as part of a pan-multiverse game between two really powerful entities.

Flash was able to travel to Earth-616 in person, but once there he found that there was no Speed Force, and so he lost his powers. Eventually he is pulled back into his universe. Quicksilver, on the other hand, has no problem using his super-speed on New Earth -- though he does lose the fight w/ The Flash in that setup.

So, yes, it is true that in at least one case where The Flash found himself in a universe that is not part of DC's usual multiverse, there was no Speed Force and he lost his powers.

    Actually, that's a different crossover, and AFAIK Flash never lost his speed there. The one I was referring to is dc.wikia.com/wiki/JLA/Avengers

  • @MikeEdenfield So you are telling me, by that last part of flash having lost his powers, that despite flash having lost his powers, he won against quicksilver, how? Does flash still have his speed, but loses all his speed force related powers like IMP or time travel or other things speed force specific? Also, by your analogy, the Dc multiverse can be a part of the Marvel omniverse, if marvel can also be considered to have a omniverse?

  • no, you misunderstood. He lost his powers and was forced back to New Earth; Quicksilver fought him on DC territory and lost.

Well...I can give one sort-of example where Barry Allen traveled to the Marvel Universe and did indeed retain his speed. How canonical you want to consider it is up to you. But, arguably, according to Marvel he absolutely kept it. How DC felt about it is another matter entirely.

Also, Flash did retain his speed during Marvel VS DC when he did indeed beat out Quicksilver.

  • does Marvel vs. DC technically take place in either Earth-616 or New Earth? I got the impression even in Vol 2 (where flash appears) that the universe were starting to merge together but I'm not entirely sure...

  • I was under the impression that before the Merge, the heroes were transported between universes for their fights, but the universes weren't merging yet. We started getting some wonkiness with this with Parker working for the Planet, admittedly, where nowhere else that I recall do we see any type of merging. That said, there's no indication about whether Quicksilver teleported to Flash, or Flash teleported to Quicksilver. Either way, they raced and Flash won.

As KutuluMike pointed out, the DC Universe is actually a multiverse, and within that multiverse, the various members of the Flash family seem to retain their powers, regardless of which universe they're in. As to whether they'd retain their powers outside of that multiverse, there's conflicting evidence on that.

In the JLA/Avengers crossover from 2004, Wally West was unable to access the Speed Force while in the Marvel Universe, and consequently had no powers whatsoever.

JLA/Avengers #1, page 22.

JLA/Avengers #1 (September, 2003)

Steel subsequently built Wally a harness that stored up Speed Force energy while he was in the DCU, which he could then tap into while in the MU.

Avengers/JLA #2, page 23.

Avengers/JLA #2 (October, 2003)

Wally also appeared in the earlier DC Versus Marvel crossover from 1996. His powers seemed to work fine in that crossover, although it wasn't explicitly stated which universe he was in in the few scenes he appeared in, and the universes were shown to be merging to some extent, with Four Freedoms Plaza (the Fantastic Four's HQ at the time) popping up in Metropolis, right between the Daily Planet and LexCorp buildings.

DC Versus Marvel #1, page 23.

DC Versus Marvel #1 (February, 1996)

In the first sequel series to DC Versus Marvel, though, DC/Marvel: All Access, Wally (along with the rest of the JLA) was explicitly transported to Dr. Strange's Sanctum Sanctorum in the Marvel Universe, and his powers seemed to work just fine.

DC/Marvel: All Access #4, page 7.

DC/Marvel: All Access #4 (February, 1997)

Impulse was also transported to the Marvel Universe in the second sequel series, Unlimited Access, and his powers seemed to work just fine as well.

Unlimited Access #3, page 14.

Unlimited Access #3 (February, 1998)

So you can take your pick as far as the official crossovers go.

Regarding the 'Buried Alien'/Fastforward character -- who appeared in Quasar Vol. 1 #17 and #58, and was mentioned in some of the other answers -- although the character was clearly a nod to Barry Allen, I wouldn't treat his appearances as canonical appearances of Barry until and unless DC Comics officially acknowledge them as such, which they haven't, to my knowledge. In lieu of that, it's just a playful nod to the Distinguished Competition, comparable to other unofficial cameos we've seen in both the DC and Marvel universes.

By contrast, DC Versus Marvel/DC/Marvel: All Access/Unlimited Access and JLA/Avengers have been referenced within both DC and Marvel publications, so those are at least semi-canon, albeit they somewhat contradict one another.


The answer is YES. He would still have his powers.
Bart Allen aka Impulse, Barry Allen's relative from the future who is also a speedster was missing running through the speed force. Once he comes back out of the speed force he says,

"Crazy day, even for me. One minute I'm running to Canada to join Alpha--Oh Man."

Clearly Impulse was running and jumped into the Marvel Universe and was intending to join the most well know Marvel Universe Canadian superhero team, Alpha Flight. Wolverine has been apart of Alpha Flight along with several others.

Link to article on it.

Now, whether he was faster than Quicksilver, it doesn't say.


The cosmology of the Speed Force is always changing based on the era, writer, context, and accordingly its mechanics.

Grant Morrison's work-around is that basically all worlds are a part of the "DC Universe" and just about all of the rational realms (tangible, scientific, material, and real... vs. magical, spiritual, metaphysical) were surrounded and governed by the Speed Force. You can see a pictorial illustration of this principle in the infamous Map of the Multiverse:

Map of the Multiverse

During Mark Waid's era- the inventor of the Speed Force in fiction- the Force was an extra-dimensional energy used to justify everything Speedsters did. When he first developed the concept, the idea was that Flashes were like batteries and could and would eventually become pure energy beings... inspired by the idea that Barry would become the very bolt of lightning that began his career through Crisis.

Secret Origins Annual 2 - 1988

This energy being concept became the idea of carrying the Speed Force in and with them where (and when) ever they went, since they literally WERE the Speed Force. Waid predicted this for Wally down the road:

Flash of the 30th Century - Immortal Energy Being Wally

Then had Wally become this during normal continuity, until his romantic "lightning rod", Linda Park, brought him back to his senses and corporeal self. From that point on, Waid started to use romantic logic, quasi-mystical lens to interpret the Speed Force such that it was basically akin to THE Force from Star Wars ilk.

This conception has had the longest run with various writers having various takes on it. In some cross-overs, the Speed Force is inaccessible in other dimensions... but in other takes (like when Bart Allen briefly took over the role of The Flash) it was again something that could be bottled up and carried in a particular Flash never to be parted with.

Finally, Geoff Johns innovated on the Speed Force with a nonsensical word-salad of technobabble explaining how Barry Allen is and will forever be the source of the Speed Force, generating it by using it.

Complete gibberish - but argues its inescapable

The goal was primarily rhetoric to justify Barry's return and Wally's demotion, but it also served to suggest Flash is inseparable from the Speed Force. Which, incidentally, aligns nicely with Barry's cameo in the Marvel Universe as "Buried Alien" wherein he still had his speed and trounced all-comers in a cosmic race.

enter image description here

In sum, your friend has an argument that Flash can be separated from the Speed Force- and thus his powers- based on the venue of the race; but there are many counter-examples to the contrary allowing Flash to maintain his speed across universes and continuities, which use a different reasoning for access-to or carrying-of the power (be it always accessible, or carried within, or becoming it, or generating it). Given the variety of treatments, no one interpretation should be dispositive.
