VIDEO : New Look At Mysterious 'Avengers 4' Thanos Cake Reveals A New Arm

A new photo of the Avengers 4 celebratory wrap cake has revealed another one of the arms hoisting the Mad Titan atop the cake. On the right side, Black Widow, Captain America, and either Black Panther or an Outrider seem to be holding the cake together. The character was absent from the Avengers: Infinity War trailer, so his full on-screen appearance has yet to be revealed. Along the bottom of the cake is a lining with symbols for the key members of the Avengers: Hulk, Captain America, Iron Man, Thor, and Black Widow.
