Along with more looks at the traditional yellow Iron Fist mask, the newest element introduced in the trailer was still a familiar one, as Sacha Dhawan’s Davos enters the limelight as the big Season 2 antagonist, and his power-filled evolution to comic book alter ego Steel Serpent was brought up big-time in the trailer, with the snake logo popping up as a tattoo on Davos’ back as he appears to be trying to sap Danny of his powers.
And going from that moment, it’s assumed that Davos’ red-fist powers have something to do with the rotted-out corpse of that other K’un-Lun warrior that’s shown.
