The children of Krypton are coming out en force on Supergirl.

The Man of Steel will team up with his little cuz in the season 2 premiere, but Clark Kent (Tyler Hoechlin) and Kara Danvers (Melissa Benoist) won't be the only Kryptonians roaming around National City this fall. Mon-El (Chris Wood) has arrived, and episode 2's title pays homage to the fact that the trio is the last of their kind.

Titled "The Last Children of Krypton," the Oct. 17 event will air in the wake of Mon-El's arrival. It's unknown whether this iteration of the hero will actually be a Kryptonian, but even if he's not, the hour will feature both Hoechlin and Benoist's heroes as they battle the series' next big threat.
