Concept art from Avengers: Endgame has surfaced online featuring The Hulk holding his own against Thanos, among other abandoned ideas.

The concept art, which was reportedly shown at D23, sees Hulk delivering a massive blow to the Mad Titan's chin. This scene might have been a rematch between the two powerhouses after the Green Goliath was decidedly manhandled in Infinity War.

The second image shows Iron Man taking flight, flanked by War Machine, Rescue and Spider-Man. Finally, the third image sees Tony Stark and Pepper Potts kissing in the midst of the film's final battle. Fans noted that both these scenes could have been callbacks to previous moments from the Iron Man franchise.

However, as this is merely concept art, it's unlikely these scenes were ever actually filmed.
