Grodd, the A.T.O.M. and some shocking reveals in new Arrow + Flash sizzle reels

The CW has built a tiny superhero empire over the past few years with The Flash and Arrow, and it looks like things are only getting bigger in 2015. There’s no arguing the point: The CW definitely knows how to make a sizzle reel sizzle.

Both shows were out in full force at the recent PaleyFest event, where the studio showed off some spoiler-filled trailers that drop some huge bombshells for the back halves of both shows current seasons. Secrets will be revealed, and new characters are definitely coming into play. Seriously, if you don’t want to be spoiled, walk away now.

In the Arrow trailer, we get to see a lot more of Ray Palmer’s A.T.O.M. in action, and it doesn’t take the billionaire genius long to figure out Oliver Queen is actually the Arrow — and it sounds like he wants to do something about it. There’s also some payoff on that Ra’s al Ghul cliffhanger, and it sounds like the insanity in Starling City could have Oliver seriously considering his offer.

On The Flash, the mystery surrounding Dr. Harrison Wells looks to be paying off nicely. Along with the lingering investigation into Barry’s mother, it looks like the Reverse-Flash story will be doing a lot of the narrative heavy lifting from here on out. We also got to see the Rogues causing all kinds of trouble (plus Mark Hamill!), and just watching this trailer, it's impressive how large of a superheroic world they’ve managed to build in less than one season.

Watching these two sizzle reels back to back, it's amazing how you can literally feel the different vibe they’ve established for the two shows — while still keeping it all connected. There also seems to be more than a few crossovers playing out in the footage below (A.T.O.M. at STAR Labs!), so don’t worry, these worlds will still definitely collide from time to time. Check out the trailers below and let us know what you think:

The Flash airs Tuesday nights, and Arrow airs Wednesday nights on The CW.
