As one of the most powerful superheroes on the small screen, Kara Zor-El has faced off against a number of foes since Supergirl's debut. However, her conflict with new big bad Reign is shaping up to possibly become one of the best of the series, as Kara's recent encounter with the latest (and wholly unique) villain left the Girl of Steel with some severe bruises to tend over the show's winter hiatus. Things don't look great for Kara, but Supergirl has officially cast This is Us alumni Krys Marshall as a potential new ally in the latter half of Season 3.
With the casting of Krys Marshall, Supergirl has once again bolstered the ever-expanding supporting roster of heroes and allies that can help Kara Danvers through a tough spot, assuming that Marshall's Julia Freeman is indeed an ally. Not too much is known about what we can expect from Marshall when she appears, but we do know that she will portray her characterJulia is a National City-based musician who knows some critical information about Reign and her "real" identity.
As of right now, the TVLine report announcing Krys Marshall's casting as Julia does not explicitly lay out how the new character will factor into the battle against Reign, but whatever information she's holding is obviously important. Even with the extra knowledge she brings to the table, it's clear that Supergirl will also still need plenty of raw brawn to help overtake this latest nemesis. After all, it's not often that we see a bad guy make Kara legitimately bleed without the use of Kryptonite.
In addition to her upcoming stint on The CW's Kryptonian-centric series, Krys Marshall is slowly but surely becoming a familiar face in the small screen landscape. As mentioned earlier, she recently appeared on This is Us, and she also has credits on shows like One Day at a Time and How I Met Your Mother. Julia is set to recur through the second half of Supergirl Season 3, but it remains entirely possible that the character could potentially stick around beyond the conflict with Reign if she proves popular with the Supergirl fanbase.
Supergirl will return to The CW on Monday, January 15 at 8 p.m. ET and then hand off its timeslot to Legends of Tomorrow for a portion of the spring schedule.
