Agent Carter/Agents Of S.H.I.E.L.D. Dubsmash War Video Compilation

Who needs Captain America 3 when Marvel already has an entertaining Civil War?

This past weekend at San Diego Comic-Con, Agent Carter's Hayley Atwell (Peggy Carter) and James D'Arcy (Jarvis) took part in a Dubsmash battle versus Agent of S.H.I.E.L.D.'s Clark Gregg (Phil Coulson) and Chloe Bennet (Skye/Daisy).

The first 2 rounds were pretty civil, but once they got to the third and final round Hayley and James turned it up a notch by digging up "Uh Oh," a song sung by former Chinese pop star Chloe Wang, AKA Chloe Bennet. They even wore the headbands like the one Chloe wore in her "Uh Oh" music video.

Chloe and Gregg didn't take that lying down. They put together an incredibly well choreographed performance to Queen's "We Are The Champions." But the piece de resistance is at the very end when Gregg pops up wearing Agent Carter's costume.

Check it all out in the video compilation video below. Make sure you stick around to the very end for Hayley's priceless reaction to Gregg in drag.

Marvel's Agents of S.H.I.E.L.D. will return to ABC for Season 3 on September 29. Marvel's Agent Carter returns to ABC's Tuesday nights in January 2016.
