If Supergirl and I travel around the globe in opposite directions at just over mach 7, we should be able to create enough centrifugal force to slow the Earth's rotation. Is it really possible to do such thing in reality No. It's completely ridiculous. Physics doesn't work that way, nor does space-time. Indeed, the speed they mention "Mach 7" is ...

*Season 4 Finale Update The girl has revealed herself to be Nora West-Allen, the daughter of Barry & Iris although whether she follows the same story-line history as the comic version remains to be seen. We don't know (as of pre-S4 finale), but... Assuming this is intended to be significant * there are a couple of likely possibilities... * - Which is ...

First, why I don't believe they meant J'onn: In S01E17 (Manhunter), Colonel Harper approves his transfer to Project Cadmus, and en route J'onn is freed by Kara and Lucy. As far as we know, Non never knew that J'onn was imprisoned, and even if he did, Non would be able to tell from asking Lucy or checking the prisoner's list that J'onn isn't there anymore. ...

Arrow Wikia, listed it quite well: Green Martian physiology: Like all Green Martians, J'onn possesses several incredible powers. Overall, J'onn is an extremely powerful being with even Superman referring to him as "the most powerful being on Earth". Camouflage: J'onn can blend within the environment by changing the appearance of his form to ...

When Non first set off his Myriad device, Superman did fly in to help. He was caught in the device's grip and turned into a slave like everyone else. It was hypothesized that being raised by humans from the time he was very young had affected his brain enough to make him susceptible to Myriad; Kara, being raised by Krpytonians until she was a bit older, was ...

In-universe: this is unexplained, but sort of makes sense. Kara Zor-El arrives on Earth as 14 year-old girl. She's a newcomer on a strange planet, and is about to have a hell of a time learning to fit in. One of the ways to make this a touch easier for her would be something as simple as continuing to use her real first name, which, thankfully is a not-...

The easiest way to make sure you watch everything in order is to watch them by air date. Even if you don't watch them live or DVR'd, you can just use a Google search for "Flash episodes" or Ärrow episodes" to see their air dates. However, it's pretty easy this year to binge watch them. So far the only crossover point has been the big four-part crossover, ...

The actual quote is But in secret, I work with my adoptive sister for the DEO to protect my city from alien life and anyone else that means to cause it harm. I am Supergirl. So she doesn't generalise ALL aliens she's referring to aliens that mean to cause harm. The emphasis is on mean to cause harm ...not on who/what is causing the harm. Arguably, this ...

The way they define the term, no; the way fans define the term, yes. There have been several cases where they producers have used the term "Arrowverse", or have otherwise described the "world" where Flash and Arrow exist. In those cases, they have always kept Supergirl separate. Early on, in one of the first interviews about Supergirl, Andrew Kriesberg ...

Because they want the show to just be about Kara: “Our prototype is the way the president is seen on Veep,” executive producer Ali Adler tells EW, referring to the HBO drama’s clever way of mentioning, but never showing POTUS. “It’s certainly [inspired by] so much of what Julia-Louis Dreyfus’ character goes through. Ultimately, this is a show about ...

From the word of god himself, executive producer Andrew Kreisberg, god's employer said so: DEADLINE: Even though this is a crossover that occurs mainly on the CBS, are we going to see any reference to it on The Flash? KREISBERG: Yes, you’ll actually see the moment when Barry went on this experience and when he came back, for sure, in Tuesday’s ...

Yes. The episode doesn't go into much lore, and the basic premisses are explained to the Audience via explanations to The Flash/Barry. The biggest issues would be: But Callista Flockhart's character sums those up nicely (well, condescendingly) as well.

Supergirl happens in one of the various unnumbered parallel universes to The Flash and the Arrow-verse. It is neither Earth-1, where Arrow, The Flash, Vixen, or Legends of Tomorrow occur, nor Earth-2, home to Jay/Zoom, the 2nd Harrison Wells, and Jessie Quick, where technology seems to have taken off decades earlier (Very Zee-Rust). Update: A season later, ...

Plausible reasons: Age difference. Either the symbol is different for children then it is adults, and Clark has been using the child one because he doesn't know, or because Kara was already a teen/young adult and is using an older version of the crest. Clark was born later, hence a newer one. Or as Dave mentions, they are of the House of El, but not of the ...

The 38 is, apparently, a reference/homage to 1938, the year in which the first Superman comic was published. Wikia - As far as the comics are concerned: Earth 38 is the Earth of the 'local' New 52 Multiverse most accurately reflecting DC's publishing history, as heroes appear on this world when they did in the real world. It is therefore probable that ...

It does look a lot like she's waving to someone off-camera, possibly the person controlling her flight harness. That would be a bit odd, though, since the shot's clearly not finished, as there's dialogue still going on. So, while it doesn't really look like it, I think it probably was intended to be in character. She begins waving in response to Mon-El ...

We now know that she is the daughter of Barry Allen and Iris West-Allen and her name is Nora West-Allen. She is named after her deceased grandmother Nora Allen who was killed by Reverse Flash. She is also a speedster and goes by the alias XS. She has both purple and yellow lightning showing characteristics of both her mother and father. Her name is different ...

Well, something the size of a human moving at Mach 7 (or 700) would have approximately zero effect on the rotation of the Earth. Stopping the rotation of the Earth would again have approximately zero effect on how fast time was passing on Earth in relationship to the rest of the universe. Some effect, yes, enough to matter? No. Different relative speeds ...

Because Brainy is from the 30th century, and knows his history. He presumably knows exactly who Nia is "supposed" to be with in the timeline in order to eventually continue the line of Dreamer all the way along to the Legion of Superheroes in his time. If he is with Nia, then he potentially derails that bloodline and erases his friend from existence. Or ...

According to this quote from Andrew Kreisberg the creator of the 4 shows As revealed during The Flash-Supergirl crossover last year, Supergirl hails from a different universe. Are you planning on bringing Supergirl into our universe? Not for her entire world, but Kara will be traveling from her dimension to our dimension, “our” being the world ...

After the pilot it gets a lot less clunky. In fact, in the changed intro, he's mentioned by name in every episode: something like "you may know his story" was changed to "..and become Superman". And he's usually referred to as either Clark or Superman throughout the rest of the season, depending on who's mentioning him. I think in the pilot they really ...

They are clearly allowed to mention him, since they do so at least once in the pilot, and several more times during the course of the series. They also make sure to work in every one of his usual comic book nicknames (which people in-universe use to refer to Kal-El pretty frequently). As far as I know, the writers have never specifically explained why they ...

If you're asking about significant changes to the plots, characters, etc, then no. The episode that aired on 10/26/2015 was the same episode that originally leaked in the spring of 2015 in every meaningful way. It seems like there were some very minor changes made in the editing process, probably for time constraints (e.g. I there's a line of dialogue, ...

The Supergirl crossover aired way early, because of the difference in schedules between CBS and the CW. As I understand it, the crossover takes place entirely within a single Flash episode that will air tonight (I think) and the whole thing will be explained. But the basic answer to your question is yes, the device Barry has is based on the blueprints he ...

tl;dr: There is no need. Why would Non need to? He is just as Kryptonian as Clark, what could Superman do for him that he cannot just do himself? Technically, Non could have used him to keep Kara busy, but - like he tells Indigo - he could have killed her himself (meaning he doesn't need Kal-El for that). He thinks nobody can do anything to stop him. ...

In The Flash Season 3 Episode 8, Cisco and Barry are trying to recruit Supergirl and Cisco says that the tachyon device tracked Barry to Earth-38 when he visited Supergirl the first time.
