A few days ago, we brought you two brief new promos for the upcoming fourth and second seasons of Arrow and The Flash. You can find those by clicking here, but The CW has today released two extended trailers which reveal lots of new footage and details about both.

Arrow’s new trailer features lots of great action scenes and even hints that Oliver and Felicity may be about to take their relationship to the next level. The Flash’s meanwhile confirms that Zoom is responsible for sending Earth-2 villains to Central City as he wants to kill the Scarlet Speedster. We also get to see more of Adam “Edge” Copeland as Atom Smasher.

Curious to learn more about what’s to come in both Arrow and The Flash this year? Well, you should most definitely click here then! Below are the synopses for both of the shows:

After defeating his most formidable foe to date and riding off into the sunset with longtime flame Felicity Smoak, Oliver Queen left Starling City with the hopes of beginning a new life. But will Oliver ever truly be able to leave behind his past as the Arrow, and, if so, what becomes of the team he has worked so hard to assemble? Will Diggle, Thea, and Laurel be left to continue Oliver’s crusade without him? And with Malcolm Merlyn having ascended to the top of the League of Assassins as the new Ra’s al Ghul, is anyone really safe?

Following the defeat of Barry Allen’s arch-nemesis Eobard Thawne (a.k.a. Reverse Flash), Team Flash quickly turned their attention to the singularity swirling high above Central City, which fans last saw consuming everything in its path. Armed with the heart of a hero and the ability to move at super speeds, Barry charged into the eye of the singularity, but will he actually be able to save his city from impending doom? Check out the promos below.
