Supergirl: Your First Look at Hellgrammite

During tonight's Supergirl trailer, fans got their first look at Justice Leak as Hellgrammite, a Superman villain created in the '60s and then reinvented in the '80s before finally ending up squaring off with the Man of Steel's cousin starting later this year on TV.

Like another just-revealed villain from the series, Reactron, Hellgrammite has terrestrial origins, rather than alien ones. That's interesting, if only because Supergirl's sister and her employers at the DEO are ostensibly on the lookout for alien menaces. Instead, will Supergirl be squaring off primarily with mutants and monsters they've created -- intentionally or inadvertently -- themselves? Given what we know of Red Tornado and Lucy Lane's "Superwoman" storyline from the comics, it makes a strange kind of sense.

In the comics, he was an entymologist who treated himself with a serum that ultimately mutated his body horribly. Many of his stories in the comics -- especially during the pre-Crisis on Infinite Earths stories -- involved essentially conscripting people to be his servants by transforming them into smaller, weaker versions of himself; a parasitic or somehow venomous power set certainly doesn't seem like it would feel out of place with that gaping, ugly maw.

Supergirl is an action-adventure drama based on the DC Comics character Kara Zor-El, Superman's (Kal-El) cousin who, after 12 years of keeping her powers a secret on Earth, decides to finally embrace her superhuman abilities and be the hero she was always meant to be. Twelve-year-old Kara escaped the doomed planet Krypton with her parents' help at the same time as the infant Kal-El. Protected and raised on Earth by her foster family, the Danvers, Kara grew up in the shadow of her foster sister, Alex, and learned to conceal the phenomenal powers she shares with her famous cousin in order to keep her identity a secret. Years later, at 24, Kara lives in National City assisting media mogul and fierce taskmaster Cat Grant. She works alongside her friend and IT technician Winn Schott and famous photographer James Olsen, who Grant just hired away from the Daily Planet to serve as her new art director. However, Kara's days of keeping her talents a secret are over when Hank Henshaw, head of a super-secret agency where her sister also works, enlists her to help them protect the citizens of National City from sinister threats. Though Kara will need to find a way to manage her newfound empowerment with her very human relationships, her heart soars as she takes to the skies as Supergirl to fight crime.

The Supergirl series premiere airs Monday, October 26 at 8:30 PM. The series will then move to its regular Monday 8 PM slot the following week, November 2.
