Season 2 also welcomed a new alien to Team Supergirl, the Daxamite Mon-El (Chris Wood), who has grown closer to Kara over the course of the season.
Between seasons 1 and 2 of Supergirl, the show went through somewhat of a soft reboot as it changed networks from CBS to The CW for the series’ sophomore outing.
Now, an extended trailer for the second half of Supergirl season 2 features the return of a season 1 villain as well as the antagonist in The CW’s four-show Invasion! crossover event.
The CW released the new trailer [above], which teases the return of – “the one, the only” – Leslie Willis aka Livewire becomes more deeply entrenched in his identity as the National City vigilante, Guardian.
