A newly-released extended trailer for the January 15 winter premiere episode of Supergirl reveals our first good look at Jesse Rath as Brainiac 5.
The episode is called the “Legion of Super-Heroes” – a moniker that is name-checked by Winn within the trailer – and you can see the new trailer below.
UPDATE: The CW has now released an even longer version — twice the length, with much more of the Legion in their costumes! Official promo images for “Legion of Super-Heroes” can be found here.
MEET THE LEGION – Struggling to heal from her injuries inflicted by Reign (Odette Annable), Supergirl (Melissa Benoist) remains in a dreamlike state, unable to be reached. Mon-El (Chris Wood) recruits one of the Legion members, Brainiac-5 (guest star Jesse Rath), to try to bring her back. Meanwhile, Reign continues her rampage on the city so the DEO teams up with the Legion of Superheroes to try to stop her. Jesse Warn directed the episode written by Derek Simon & Eric Carrasco (#310). Original airdate 1/15/18.
