'Captain America: Civil War' Trailer Reveals Major Bucky Barnes/Winter Soldier SPOILERS

The second trailer for Captain America: Civil War had some amazing new footage including a quick look at Paul Rudd's Ant-Man being catapulted from Hawkeye's (Jeremy Renner) arrow and the famous shot of Tom Holland's Spider-Man at the end of the teaser. However, the trailer may have also revealed a major spoiler about Sebastian Stan's Winter Soldier!

The Civil War trailer offered more fight scenes between Chris Evans' Captain America and Robert Downey Jr.'s Iron Man, and Reddit user Laffy_Sapphy has pointed out that one of the sequences actually features a fleeting glimpse at Bucky Barnes lying on the floor, obviously injured. Just how extensive is his injury? Let's just say that he looks unconscious and his bionic left arm appears to have been torn off. Get the PAUSE button ready.

If you are still having trouble finding the moment, you can get a closer look here.

So what happens to Bucky in Civil War? Some fans believe that the Winter Soldier's arm may have been blown off when he attempts to pull off Iron Man's arc reactor from his suit, as seen in the first trailer. There is also a possibility that Tony may have managed to tear it off himself and knocked out Bucky in the process.

But does this mean that the Winter Soldier is one of the casualties of Civil War? One of the most obvious kills so far has been Don Cheadle's War Machine, who has repeatedly been shown seemingly unconscious with his own arc reactor torn off. Is it possible that Tony is trying to get back at Bucky, who has been revealed to have shot James Rhodes in the new trailer? If so, this certainly lends a new emotional side to the fight between Tony and Steve Rogers.

Find out if the Winter Soldier survives when Captain America: Civil War premieres on May 6.
