ATTENTION: Between episodes 1 × 04/3 × 04 and 1 × 08/3 × 08; passes the animated series “Vixen” that has 6 episodes of 5 minutes and has crossover with both series. We recommend to watch after the episodes 1 × 06/3 × 06, to give more meaning to the continuity of the three series.

We recommend: Although it does not have a very big impact on the series universe at the moment, we recommend watching the first (and only) season of the “Constantine” series, canceled by NBC, with only 13 episodes. The ideal is to watch the series before the episode 4X05 “Arrow”, where there is the intersection of both stories.
