The fourth year of the Arrowverse saw two new massive arrivals, Supergirl and DC Legends of Tomorrow. Series: Arrow | The Flash | Supergirl | DC Legends of Tomorrow

Once you’ve watched the crossovers you can view the remaining episodes of Arrow and The Flash however you please, respectively. It’s our recommendation that you watch the first seven episodes of Arrow, and then the first seven episodes of Flash before watching the crossover. Every future season of Arrow and The Flash would have a crossover episode in the eighth or ninth episode of the season. The crossover between Arrow and The Flash was officially the very first of the Arrowverse and laid the groundwork for future crossovers. The Flash hadn’t aired on The CW at the time, but Grant Gustin as Barry Allen was an instant hit with Arrow fans. Season 2 did mark the beginning of the future of the Arrowverse when Barry Allen debuted in episodes 2×8 and 2×9 of Arrow. One of the best seasons of Arrow, and easily of the entire Arrowverse, season 2 also goes uninterrupted as it was the only Arrowverse series still available at the time. Year 1 of Arrowverse was literally just Arrow so that’s the best place to start. We start at the beginning with season 1 of Arrow.
