Avengers: Infinity War - Every Death Ranked Worst To Best
13. The Collector
Cause of Death: Burned (probably).
Now, in fairness we never actually get visual confirmation that The Collector (Benicio del Toro) dies, but considering that Thanos burned down his museum, it's incredibly unlikely he would dare leave him alive.
Again, we don't see his corpse, but the implication is nevertheless pretty grim: we see the Reality Stone-created projection of the Collector inside one of his own display pods, and when the ruse is pulled back, the pod is then aflame, seeming to suggest his body is probably inside of it.
It's possible Thanos just beat him to death before razing the museum, but either way, his body is most certainly burned to a crisp now. The reality-warping reveal is what makes this so effective, even though we don't actually have 100% confirmation of it yet.
