Avengers 4: 6 Dead Characters Who Will Definitely Appear
4. Vision
His Death: Avengers: Infinity War. After Thanos arrives in Wakanda and has a leisurely stroll through several other Avengers, he comes face-to-face with Vision, reversing the android's first death by using the Time Stone, then finishing the job himself.
His Avengers 4 Role: Several pieces of Avengers 4 concept art have leaked in 2018, and over the summer, we got some that pertained directly to Vision (via CBM).
The images show the character with a fresh new design, lacking his signature red, gold and green colours and instead looking plain, white and grey. This could be because the images weren't final, or, more interestingly, it could be a clue that Vision will return in Avengers 4 as his West Coast Avengers iteration from the comics. In this storyline, Vision is abducted and dismantled, later to be rebuilt by Hank Pym. This results in him becoming emotionless and pale, losing all his colour.
Since Vision died in Infinity War, the stage is set for a West Coast Avengers-style return (rebuilt by Shuri, perhaps?), complete with ghostly colour scheme - maybe the loss of the Mind Stone will result in this change? Marvel are obviously not going to acknowledge that the concept art is real, but Vision's return is firmly on the cards.
