3. The Arrow
The promo teaser for The Flash (which you can see by clicking here) featured The Arrow, but this full-length trailer reveals that he’ll also make a brief appearance in the pilot episode. It was Barry Allen who gave Oliver Queen his mask, so it seems appropriate that it will be Ollie who inspires him to also become a hero. The fact that these two share the same universe – Barry was introduced in Arrow, but it would have been easy for them to move on without ever referencing it again – also leaves the door open to a crossover in the future. Just imagine who great it would be to see a four-part story arc taking place across both Arrow and The Flash! There’s a lot of potential here as a result, and this moment alone is incredibly cool as we see these two heroes together.
