Iron Fist Season 2 trailer still

Netflix/YouTube

The Danny-Davos rivalry is back.

Netflix released the official trailer for "Marvel's Iron Fist" Season 2 on Wednesday, and it picks up with the fist-pounding adventures of Danny Rand (Finn Jones). His friend-turned-foe Davos (Sacha Dhawan) is also back, and he is harboring an old grudge from their days training together. As Colleen Wing (Jessica Henwick) notes in the preview, Davos always wanted the Iron Fist, and Davos shows he will make Danny suffer.

"The Iron Fist is not a weapon to be held," he tells Danny. "It is to be used."

Expect lots of action, including some pretty brutal scenes. The trailer shows multiple battles between Danny and Davos, and they're definitely bloody. Like all of Netflix's Marvel TV series, "Iron Fist" isn't messing around.

Danny deals with other dangers in the trailer, too, but his rivalry with Davos dominates the trailer. Watch below.

All episodes of "Iron Fist" Season 2 hit Netflix on Sept. 7.
