5. The Vision

Three Deaths: Avengers the Children’s Crusade #9, Avengers #500, Infinity Gauntlet #4

Death also looks like a possibility for The Vision. After all, Thanos needs that Infinity Gem that happens to be crammed right in our colorful robot boy’s skull. But that doesn’t mean that anything’s certain.

First, we have our Infinity Gauntlet #4 death, when he went out alongside some others. Then there’s the first part of Avengers Disassembled, Avengers #500, in which the Scarlet Witch brings on machinations that cause She-Hulk to lose control and rip The Vision in half. That kills him.

The Vision was rebooted from a backup drive in Iron Lad’s old suit back in Young Avengers. Buuuuuuut that wouldn’t last, either, as Iron Lad destroyed that version when he came back and went all Kang Jr. on him. But Classic Recipe Vision returned, and is still around at present.
