5. Nebula
One of the daughters of Thanos, I don’t see Nebula not wanting to confront her father at some point of the narrative. I don’t see this interaction going well either.
4. Drax the Destroyer
Like Nebula, Drax has a personal vendetta against Thanos. We have also seen this character go swords blazing into battle with less powerful villains 1 on 1, looking at your Ronan, when he has a personal grudge. Who is to say he won’t do the same thing to Thanos?
3. Iron Man
The Avenger that started the MCU, Iron Man has come close to death a few times over his 10 year span in the Marvel Cinematic Universe. And since many see this film being the end of phase 3 of the MCU, it would be a fitting end to the character.
2. Captain America
Now I’m going to dive into the Infinity Gauntlet comic where this film gets its narrative. Even though almost every major character dies in this comic run, Cap’s death is very significant as he is the last man standing. He also goes head to head with Thanos in the trailer which isn’t very promising.
1. Vision
This prediction can be summed up in one phrase, “HE HAS THE MIND STONE IN HIS HEAD.” And since he needs the stone to live, his chances of surviving Thanos are slim to none.
