2) Hulk In Armour
The big climax of the trailer is what we’ve all been waiting for – the appearance of the Incredible Hulk. We haven’t seen Bruce Banner’s alter ego since he left Earth at the end of Avengers: Age of Ultron. Both he and Thor were absent for Captain America: Civil War and now we finally know what they’ve been up to. It turns out that Hulk has ended up on Sakaar as well, and looks to be one of the Grandmaster’s chief gladiators.
This is exactly the plot of popular comics storyline Planet Hulk. The only difference in that is that the Illuminati – a team of elite Avengers – decided to jettison Hulk into space for the Earth’s safety. The storyline also led to World War Hulk, where Hulk returns to Earth and goes on a rampage to get revenge. We wouldn’t expect the second storyline to really be tackled in the movies right now, though we hope it will someday.
For the time being, we’re just happy to see Hulk decked out in gladiator armour, as it’s one of those overtly comic book-y images you don’t ever expect to see on film.
