Davos summons his own glowing fist in a new promo for the second season of Marvel's Iron Fist.

Sacha Dhawan was introduced in the ninth episode of Season 1 as Davos, Danny Rand's childhood friend turned rival who journeyed to New York City intent to bring the Iron Fist back to the mystical city of K'un-Lun. Marvel fans know him better as the Steel Serpent, sworn enemy of Iron Fist, but viewers didn't need to have extensive comic book knowledge to know the two were being set on a collision course for Season 2.

The new 19-second clip plays up Davos' envy of Danny (Finn Jones), who achieved the title of Iron Fist instead of him, only to abandon his duties at the protector of K'un-Lun when he was needed most. Over shadowy images of Davos in action flashes the words "I have become the thing you never head the strength to be," a taunt obviously targeted at Danny Rand. The footage closes with a shot of Davos' fist, glowing red in contrast to Danny's yellow.
