This week's DC TV roundup is a big one, as we finally have a first look at next Tuesday's epic Supergirl series finale! Plus, The Flash: Armageddon, Batwoman, Legends of Tomorrow, and Stargirl!

Next Tuesday, Supergirl brings its six-season run to a close with an epic two-part series finale that will see the Girl of Steel (Melissa Benoist) and all of her Superfriends take on the biggest challenge of their lives as they fight off the combined efforts of Lex Luthor (Jon Cryer) and Nyxly (Peta Sergeant).

Plus, expect a number of unexpected surprises, as the final hours will also play host to Alex (Chyler Leigh) and Kelly's (Azie Tesfai) big wedding day, a tragic funeral for a friend, and the battle to save National City. 

Meanwhile, Matt Ryan finally makes his return to Legends of Tomorrow as a new character named Dr. Gwyn Davies, and on Batwoman, Ryan Wilder (Javicia Leslie) does some recon at Wayne Enterprises. 

As for what's to come in a few weeks, we have our first official poster for The Flash: Armageddon, which sees the Scarlet Speedster (Grant Gustin) team with The Atom (Brandon Routh), Black Lightning (Cress Williams), Batwoman, Green Arrow (Katherine McNamara), and Sentinel to take on Despero (Tony Curran).  

Finally, Stargirl ended its second season by making toast of Eclipso (Nick E. Tarabay), and we got a preview of what's to come in season three. "Frenemies" will see the Crocks move next door, and it looks like the big bad of the season will be Mister Bones, voiced by Keith David!
