We know that The Flash is a speedster. But I recently learned that only the Flash can open the time portal, while Reverse-Flash & Professor Zoom cannot.

If Zoom opened the time portal, it would have different effects. There must be unique abilities that only The Flash possesses. Like time-travel, etc. Otherwise why would Reverse-Flash and Professor Zoom looking forward to stealing the Flash's speed?

  • No, it is not..

  • I suggest you ask this question on scifi.stackexchange.com That forum is meant specifically for this kind of questions. If this question is related to The Flash TV series, then it's ok.

  • I'm editing Question in context to relate it to TV series 'The Flash'.

  • Is this really just about the Flash TV-show and its story and characters and not about general discussion of The Flash and abilities of his not depicted in the TV-show?

  • This is not so general but yes it relates the characters of TV series. So, basically answer should cover unrelieved powers that Flash has.

It's... complicated. Due to the Flash's extensive history in comics, cartoons, tv, and soon to be movie, there is no one definitive list of what he can do. And there are multiple Flashes, Jay Garrick, Barry Allen, Wally West, etc. The CW Flash is not a straight forward copy of comic Barry Allen, but a mixture of them.

That said, current comic canon (not yet rewritten in the New 52) is that Barry Allen is the source of the Speed Force which every other speedster uses. In essence, this makes him more powerful than all the others, and he could do anything they can, if he learns how. So there is no upper limit on what he can do compared to others.

In The Flash: Rebirth #4, Max Mercury revealed to Barry Allen that the Speed Force was created by Allen, himself, when he became the Silver Age Flash; adding that, "When [Allen runs, he generates] the kinetic wall between the present and the time barrier. It's an electrical energy that exists in every dimension, every universe, and every era. It touches every part of reality. It contains the knowledge of every place and time. The Speed Force is the all-encompassing Flash Fact."

Reverse-Flash, Eobard (in the comics known as Professor Zoom at times) is essentially using Barry's old costume, in the future. His power levels depend on Barry's power levels, but in the future. This is why he need to make Barry Stronger, in order to retro actively make himself stronger. Yay Temporal Mechanics. When he changed the past and almost killed Barry, he changed the amount of Speed Force he could absorb.

Edit: In S02E10 "The Reverse-Flash Returns", a younger Eobard says that he replicated Barry's formula. This implies a version of "Velocity 9" or "Speed Juice" in Earth 1's future. Or it's an exact copy of Barry's accident. In either case, it would mean Eobard didn't get Barry's old costume, and makes most of Season 1's wheelchair and tachyon plots "wrong"? More details required.

This is essentially also what Zoom, who resembles the Black Flash (A Grim Reaper type character), also wants. To fatten Barry up like a turkey to take his power. To drain him of the Speed Force.

There is no single power that they want of his, they want the Speed Force in his cells. The way the Speed Force powers work, they can all copy one another with practice. Most of the Flashes can travel through time. Most of them can vibrate through things. Wind Vortexes. Speed Mirages. Super Punches. This is the trick to the Speed Force, understanding it and applying it in creative ways.

Side note: All the Flash enemies tend to use the same names at various times. Eobard has gone by Professor Zoom, Reverse-Flash, Black Flash. So did Zoom, who in the comics is Hunter Zoloman, Wally West's reverse-flash. It's confusing.

  • This is a really great, in-depth answer! Is there any chance that you have any sources you could link to for this?

  • @ghostdog how do I link to 75 years of comics, multiple rebooted timelines, cartoons and direct to dvd films? The gist of this can be found on the Wikipedia pages for Barry Allen, Wally West, Speed Force, Eobard Thawne, and the dc.wikia.com for the same.

  • That's all you need to do - it can be as simple as citing a couple wiki pages that give the info so that people don't have to search high and low to verify what you said.

  • So, Wally west is also going to be flash. Now I get it. They all have same extent of speed force but how creatively they use that does matter.

  • @JayModi well. maybe? The original wally west was a ginger nephew of Iris West. Now he's her brother. And theres nothing to say he's going to become the flash anytime soon.

Reverse-flash can time travel too, he did it in episode #10, I guess but really didn't get why he hates the flash. They said zoom wants flash's speed to become stronger and faster and because he doesn't accept the fact that there is another speedster but him on any earth. He wants to be the only speedster so he took down Jay Garrick on his earth and now it's Berry's turn, they clarified only that much for now.

  • Does not answer the question. What other powers...Considering the comics The Flash does have? And reverse flash and zoom don't have. As the TV series is following the comic series.

  • They did mentioned why Reverse flash hates the flash and why Jay Garrick losts his speed but overall you answer doesn't even answer the question.
