This web series follows Cisco Ramon as he works on the Flash suit in S.T.A.R. labs.

It takes place some time after Flash S2E17, and probably before S2E18.

Season 1 of this animated webseries takes place shortly before episodes 15 and 16 of Arrow Season 3. The Arrow and The Flash feature, as do Felicity Smoak, Cisco Ramon and S.T.A.R. Labs.

Season 2 of this animated webseries features cameos from the Flash, Cisco, Firestorm and Weather Wizard as well as cameos from Felicity Smoak, Atom, Black Canary/Laurel Lance, and Green Arrow.

The inclusion of certain characters would approximately place Season 2 between 'Arrow 4×10: Blood Debts' and 'The Flash 2×09: Running to Stand Still'.

A previous version of Vixen, who held the mantle before Mari McCabe (and is her grandmother), features in Seasons 2 and 3 of Legends of Tomorrow.

The other Totems are further explored in Legends of Tomorrow Season 3.

This combines the first two seasons into a single story, with 15 minutes of never-before-seen content showing Mari's first few less than successful attempts at leading a super-hero life. Wishing to learn how to control her animal powers, she gets a job at the Zoo, working with an animal behavioral specialist, named Doctor Vargas.

Mari starts forming a bond with one of the gorillas in the Zoo, but it doesn't take long for her to get mixed up with some smugglers who were threatening Dr. Vargas. Mari helps out and everything seems to play out fine by the end as she not only stops the crooks but also feels like she now has more confidence in her powers.

There is also an end credits scene which links to the Arrow episode "Taken" which features Vixen's live-action appearance.

Although it was never originally part of the Arrowverse and was not renewed for a second live-action season, Constantine makes an appearance in S4E5 of Arrow. He appears in both the flashback and present day storylines making this series part of the Arrowverse. He is also mentioned again in dialogue in two later episodes, assisting Oliver.

In S3E9 and E10 of Legends of Tomorrow, Constantine requests the teams help.

He features regularly in Seasons 4 and 5 of Legends of Tomorrow, and appeared in the Crisis event.

(The original intended viewing order for Constantine Season 1 would have been 1, 6, 2 -5, 7 - 13 but it was changed by NBC to 1 - 13, with a line of dialogue added to explains that Zed is absent).

In Season 1 Rip Hunter travels back in time from 2166 to 2016 where he brings together a team of heroes and villains in an attempt to prevent Vandal Savage from destroying the world, and time itself. Vandal Savage was first introduced in the crossover episodes of Arrow S4E8 and The Flash S2E8.

The Ibis-Stick or Ibistick, a magical Egyptian artefact used by Vandal Savage, was previously seen in 'Constantine'.

The team features several recurring characters from both Arrow and The Flash, including Professor Martin Stein & Jefferson "Jax" Jackson aka Firestorm, Ray Palmer/The Atom, Sara Lance/White Canary, Leonard Snart/Captain Cold & Mick Rory/Heat Wave, and Carter Hall/Hawkman & Kendra Saunders/Hawkgirl.

Prior to the Crisis on Infinite Earths crossover event this series did not take place on the same Earth as the other Arrowverse shows; instead it takes place on an alternative earth in a parallel universe within the Multiverse. This is first hinted at in S2E13 of The Flash, and then Barry Allen/Flash visits this alternative Earth in S1E18 of Supergirl (this episodes takes place in the opening minutes of S2E18 of The Flash when Barry disappears for a few seconds).

On his visit The Flash namechecks Green Arrow, Black Canary, Firestorm, Atom, Zoom, Blackout and Pied Piper. We also find out that there is a Central City on Supergirl's Earth but no equivalent of Star Labs, Harrison Wells, Caitlin Snow or Cisco Ramon.

This crossover episode hints at Earth X (a world ruled by the Nazis) and a world where JFK was not assassinated (called Earth-21 in the comics). It even hints at a possible future Crisis on Infinite Earths event.

Kara states that her cousin Clark Kent (aka Superman) knows Bruce Wayne, but presumably that refers to the Earth-38 version?
