Although there are no footages from "The Flash's" season 2 and "Arrow's" season 4, the video entitled "Justice Moves to its Own Beat" shows the two distinct themes of the show. The network is trying to hype the action that's coming to both series.

Here's what we know so far about "The Flash," there will be a lot of new faces in the show like new speedsters that will help Barry Allen (Grant Gustin) such as Jesse Quick (Beane), Wally West (Keiynan Lonsdale), and Jay Garrick (Teddy Sears).

Barry's love life will head on a different direction with a new love interest named Patty Spivot (Shantel VanSanten).

Bad guys are also increasing in number including Atom Smasher (Adam Copeland) and Zoom (Tony Todd).

"Arrow," on the other hand, will see a transformation as Oliver Queen (Stephen Amell) becomes Green Arrow in the series. Not only that, Executive Producer Mark Guggenheim teased that Green Lantern just might appear in the show.

New characters are also coming headed by "True Blood's" Rutina Wesley who is playing a lady cop named Liza Warner; "Enlisted's" Parker Young who is the new love interest for Thea named Alex Davis; new love interest for Thea; and Jeri Ryan who is guest starring as a politician.

Oliver will also get help from new heroes such as Mister Terrific to be played by Echo Kellum and Hawkman to be portrayed by Falk Hentschel.

New villains will challenge Green Arrow this season headed by Damien Darhk (Neal McDonough), Baron Blitzkrieg (Jimmy Akingbola), Anarky (Alexander Calvert), and Vandal Savage (Casper Crump).

Season 2 of "The Flash" returns on Oct. 6 while season 4 of "Arrow" comes back on Oct. 7 both on CW.
