So you’re Brian K. Vaughan and you experience that proud moment when you see Marvel and Hulu turn something you created into a TV show.
EDIT: the leaked teaser is un-embed-able or has been removed.
See the tease at Screenrant.com.
With glimpses of The Pride’s rituals being shown, the power sets of the heroes are also not fully explored here either. There is a glimpse of Karolina’s powers of alien origin, but it is unclear if they will keep that background or find a new way to explain her powers. There also appears to be a shot of Molly’s eyes glowing, possibly indicating the use of her powers, but she will also likely undergo some origin changes as she is a mutant originally in the comics.
Once more of Runways begins filming and Hulu has more content at its disposal, we should be getting a trailer that better showcases the Runaways in action. Fans are anxiously awaiting the Staff of One to manifest out of Nico, see Chase dawn his gloves, and/or have Gert call upon her friendly-but-deadly dinosaur, Old Lace. However, some of those elements may have been too strange for a teaser, so keeping it simple to start could be the better strategy.
Runaways is expected to premiere on Hulu sometime in 2018.
