Avengers: Infinity War - What Is Next For EVERY Character
36. Proxima Midnight
Fate: Shredded by one of Thanos' death machines
Proxima Midnight was probably the most arrogant of the Black Order and the villain most confident in her own superiority (aside from the evangelical Ebony Maw) and it was rather fitting that she ended up being killed so viciously by one of her boss' own death machines. There can be pretty much no doubt that she's gone, either, as she was pretty much splatted on the spot.
And like Cull Obsidian, if the Avengers do somehow manage to reset the clock to before the Battle of Wakanda, then there's a possible way back for her.
35. Corvus Glaive
Fate: Stabbed by Vision
The last surviving member of the Black Order was killed by an already badly injured Vision at the tail-end of the Wakanda battle before Thanos appeared in the "endgame" - stabbed through his heart (unless his biology is wildly different to humans anyway) by the android with his own weapon. Again, pretty definitive.
If he has any chance of a return from the dead, it'll be the same time travel avenue as would revive his "siblings."
34. The Collector
Fate: Killed (off-screen) by Thanos, presumably
The only time we saw Benicio Del Toro's flamboyant Collector - apparently inspired by Liberace, though the performance has just gone wildly overboard since his first appearance, to be quite honest - he was a projection, magicked into existence by Thanos and the Reality Stone. But the very fact that the Stone was used to pull off the illusion suggests that the real Collector was dead before the Guardians arrived on Knowhere.
Don't expect to see him again - he's about as expendable as characters come in the MCU. And there's precisely nothing left for him to do now. Maybe be concerned for the poor creatures left in his collection, though - unless the Guardians freed them, they're going to starve pretty quickly.
And now on to everyone else...
