Oh, wow! If you thought DC's Legends of Tomorrow Season 1 was great, wait until you get a load of what they have planned for Season 2! The trailer has arrived from Comic-Con and there is too much cool stuff to behind. This year, when the show returns, there will be plenty of new heroes and villains.

With the help of the Justice Society of America, the Legends of Tomorrow will face off against the Legion of Doom! Warner Bros. Television's Super Hero team-up series DC's Legends of Tomorrow (Thursdays 8/7c The CW) is amping up the firepower for season two. And it has enlisting both a league and a legion of new characters to join the legendary crew of the Waverider as they embark on a new mission for the upcoming season.

While some faces may be familiar to viewers of The CW's DC Universe, others hail from the DC Universe of comics. In the season one finale, the legendary heroes encountered Rex Tyler aka Hourman (played by Patrick J. Adams - Suits) who issued a dire warning. It was to be their first encounter with a member of the Justice Society of America. During a Comic-Con 2016 panel on Saturday, July 23, the show's executive producers and cast revealed that some of Tyler's fellow JSA members would soon be making an appearance on the series.

Some familiar faces to fans are the yet-to-be-cast roles of Obsidian, Stargirl and Dr. Mid-Nite. And yet, for every force of good in the DC Universe, there stands in opposition a force of darkness.

With the introduction of new heroes, the producers also announced that the Legends of Tomorrow would also be facing off against TV's first-ever team of Super-Villains. The Legion of Doom! Fans will recognize them as Malcolm Merlyn (John Barrowman), Damien Darhk (Neal McDonough), the Reverse-Flash (Matt Letscher) and Captain Cold (Wentworth Miller).

Matt Letscher, who played the Reverse-Flash/Eobard Thawne on The Flash, will join DC's Legends of Tomorrow as a series regular. Deals with Wentworth Miller and John Barrowman were announced earlier this summer, allowing their characters to appear across multiple shows, and Neal McDonough's Damien Darhk character will now have a recurring role on DC's Legends of Tomorrow. Legends executive producer Marc Guggenheim said this.

"For season two of Legends, we decided that the perfect antagonist for TV's first-ever team of Super Heroes would be TV's first-ever team of Super-Villains, recruited from the ranks of Arrow and The Flash's deadliest adversaries. Being huge fans of the Challenge of the Superfriends, we've come to call this group our 'Legion of Doom.'"

Based on the characters from DC, DC's Legends of Tomorrow is from Berlanti Productions in association with Warner Bros. Television. The series returns for season two on Thursday, October 13, at 8/7c on The CW. Take a look at Season 3.
