In 2012, a Live Action Adaptation of Green Arrow, dubbed Arrow, aired on The CW before it got a Spin-Off, The Flash, in 2014, creating what became known as the Arrowverse.

Most of the Arrowverse originally took place on Earth-1 before the adaptation of Crisis on Infinite Earths created a new reality that merged all of the main shows into one reality dubbed "Earth-Prime." The list of shows is as follows:

Taking place on Earth-Prime:

Tropes used in Arrowverse include:
  • Adapted Out:
    • Out of the "Big Three", so far only Superman has appear, even though Batman is heavily alluded to.
    • Mention is frequently made of the Thanagarians but not so much the Gordanians.
  • The Alcatraz: Iron Heights. Protective Custody? What's that?
  • Alternate Self: Show up quite a lot. At fourteen, Harrison Wells is the current record holder.
  • Ascended Extra: In a meta-sense, not many would have chosen Green Arrow and the Flash to be the ones to launch a new Shared Universe.
  • Bigger Bad: The Anti-Monitor.
  • Cosmic Retcon:
    • Barry unintentionally enacted one in the Flashpoint arc.
    • The shows merging into Earth-Prime. As Cisco irritably spells out to Killer Frost, the inhabitants of Earth-38 and Earth-BL didn't move onto Earth-1, reality has changed so that they've all always lived on the same Earth.
  • Crisis Crossover: Happens Once a Season. Usually lampshaded by Cisco and Kara.
  • Depending on the Writer: How does Time Travel work? Depends on not only the show, but the particular episode.
  • Early Installment Weirdness: The first season of Arrow is very dark, gritty, and realistic, not unlike The Dark Knight Saga.
  • Running Gag: Across all the shows, the secret bases have very bad security.
  • Spiritual Successor: Could be considered one to the DCAU.
  • Superman Stays Out of Gotham: It's sort of hit and miss in how justified this is:
    • In terms of The Flash and Arrow, the two heroes' cities have different dynamics that don't fit well with the other. For example, the Central City Police Department can handle most of the threats that Oliver fights on their own, in addition to being far less tolerant of vigilantes than Starling City, and Central City actively needs Barry there to fight the supervillains while Oliver generally struggles to fight against metas.
      • This is stretched beyond believability at one point in Arrow where everything was falling apart for Oliver and he was willing to recruit some very morally questionable types but never even considered calling Barry.
      • Averted in the Season 1 finale of The Flash where Oliver shows up to help.
      • Barry does show up a few times in Arrow but the Rule of Drama means that he's always too busy to stay the extra minute and a half that it would take him to wrap up the episode's plot, despite Felicity asking him to stay each and every time.
    • The simple reason that Superman does not frequent National City in Supergirl is that Kara asked him not to. She's trying to build up her reputation and it would do her no favours if she constantly ran to Superman for help each time. Season 2 offers another reason: If Superman is in National City, then who is defending Metropolis?
      • Taken to ridiculous lengths in Season 3 where no one thinks to call Superman despite the Worldkillers being on the rampage (blame Executive Meddling). Properly justified in Season 4 where Superman tells Kara that he's planning to retire to Argo City given that he and Lois are expecting. That said, he leaves the door open enough that he might come back one day. Lex Luthor's whole motive in Season 4 is to make sure that this trope lasts forever by blowing up Argo.
      • Likewise, after being given breaching technology in mid-Season 2, Kara never thought to call upon Team Arrow or Team Flash for help. It's justified in Season 3 (Kara alone is stronger than all of Team Arrow, Team Flash, and the Legends. If she can't beat Reign, then the metahumans will just be in the way) and Season 4 (where human heroes would only aggravate the anti-alien climate). Why she didn't call for their help during Season 2's Alien Invasion, given that that's the exact circumstance for which Flash previously called on her for help, is not explained. Season 5's It's a Super Life seems to also justify a lack of other heroes on the basis that they would be unable to handle a Supergirl level threat.
    • Legends of Tomorrow is usually pretty good about this on two counts: They're time travelling and often not in the same time zone as their friends, and they're trying to leave a small footprint. Having the Flash in 1814 would probably cause some temporal headaches. In Season 2 however, when facing off against a Legion of Doom made up of Oliver and Barry's enemies, calling the two is suddenly not an option. Repeated ten episodes later where no one considers calling on Barry's expertise with regards to Reverse-Flash.
    • The Elseworlds crossover justified this with regards to Gotham City. Kate really doesn't like other vigilantes running around in her city and she all but orders Barry and Oliver, Oliver especially, out once their business is concluded. Barry, being freaked out by Gotham, is only too happy to oblige. And as a Bat, she only steps out of Gotham if there is a really big threat.
    • Black Lightning originally had the excuse of taking place on a separate Earth. But post-Crisis, it appears that even an invasion by a foreign power armed with metahumans can't motivate Jefferson to call his new friends. Not even Lex Luthor, now a Villain with Good Publicity, appears interested in using this to validate his fear-mongering.
