The first season of Supergirl ended with Kara rescuing a downed alien ship in Metropolis, only to be shocked by what she finds. Now we know who, or what, was in it: It’s Mon-El, a Daxamite, descendants of Kryptonian colonists in other worlds. In the comics, Mon-El becomes a superhero in his own right, often a younger substitute for Superman. His presence, however, might signal Supergirl is laying the red carpet for the Legion of Super-Heroes.

In Supergirl Season 2, Chris Wood (The Vampire Diaries) will play Mon-El, also known as Valor or Lar Gand, who will become a student to Kara’s teachings as confirmed by producer Andrew Kreisberg to EW. Mon-El eventually joins the Legion of Super-Heroes, an ever-changing alliance of teenagers.

The Legion have already made their presence known in Supergirl and in The Flash. A Legion of Flight ring, a weaponized piece of jewelry that designates membership, was seen in Superman’s Fortress of Solitude in Supergirl but also in The Flash when Barry Allen, Cisco Ramon, and Harrison Wells travel to Earth-2 — where they also witnessed the 1990 series The Flash as an alternate reality.

If Supergirl and Mon-El do welcome the Legion of Super-Heroes, they won’t be the only ones having teams. In DC’s Legends of Tomorrow this fall, not only will the Waverider be a team, they’ll also join forces with the Justice Society of America, while over at Arrow, Team Arrow rebuilds with Wild Dog, Artemis, and Mr. Terrific joining Oliver’s crusade in Star City.
