The mind-controlling aliens known as The Dominators are headed to Earth to make war over the metahumans. The big Invasion! crossover kicks off Monday, November 28th with Supergirl and continues on to episodes of The Flash, Arrow and DC's Legends of Tomorrow.

While we only know a few tidbits as to what unfolds in the crossover, the latest issue of Entertainment Weekly offers hints as to what follows.

Check out information below shared by Greg Berlanti for what's to come after the crossover:

Arrow

Prometheus unmasked! "Always in our midseason finales, we like to revist the big bad," hints Berlanti. "There's a shocking moment for Oliver. Amell elaborates: "This year's villain is a villain of Oliver's making. It allows us to revisit some stories we haven't seen on Arrow in a while."

The Flash

The annual Christmas episode will be typically tearful, but it will also catalyze a ticking-clock plot and flesh out the villains Savitar and Dr. Alchemy. Is the latter Julian? Berlanti is cagey: "Hopefully, if we ever did anything that everyone suspected, there'd still be a twist to it."

DC's Legends of Tomorrow

Stein will make a life-changing discovering, while Arrow baddie Malcolm Merlyn (John Barrowman) and Flash nemsis Captain Cold (Wentworth Miller) join the Legion of Doom. Cold died last season, so... huh? "We have a couple of ways he comes back," teases Berlanti.

Supergirl

The winter finale ends with The Flash's Barry and Cisco recruiting Kara to help kick Dominator ass. Berlanti hints at a cliff-hanger that teases a "very, very Superman-Supergirl baddie that we've referenced before." Plus, the twist that Lynda Carter's POTUS may be an alien "tees up some stuff that we'll be doing in the back half of the year."

"Supergirl" airs Mondays at 8pm ET on The CW; "The Flash" Tuesdays, "Arrow" Wednesdays, and "DC's Legends Of Tomorrow" on Thursdays.
