The sequel to Avengers Infinity War is expected to be the final outing for Downey Jr’s Iron Man.
And in this year’s Marvel epic fans were introduced to the Mark 50 suit, made from nanotechnology.
The highly advanced Iron Man armour formed itself around Tony’s body during his battle with Ebony Maw.
Nevertheless, with Avengers 4 rumoured to be set five years on from Thanos’ Snap, fans are wondering what Mark 51 will look like.
Now it seems concept art for Iron Man’s Avengers 4 suit has leaked, offering quite a different design.
Three silver helmet are shown, plus a robotic arm that looks more like Bucky’s, while there’s also two shots of an arm blaster and sword extension.
Perhaps we will be seeing a more armour/body hybrid for the Mark 51 suit, or more likely this is the internal part of the arms and helmet.
The film will begin with the original Avengers line-up needing to find a way to reverse Thanos’ Snap, which claimed the lives of superheroes who will be leading the MCU’s future films.
Captain America and Iron Man are going to have to put their differences aside following the events of Civil War.
Avengers 4 directors the Russo Brothers have teased the resurrection of the dead characters will “come at an incredibly high cost”.
With this in mind perhaps Tony Stark will have to sacrifice himself to save his friends.
Avengers 4 will be released in UK cinemas on April 26, 2019.
