of the characters that I can remember being confirmed...
Can't be killed because they need them for more movies:
- Black Panther (along with Shuri and M'baku)
- Strange
- Carol
- Star-Lord, Rocket, Groot
- Parker
- Ant-Man/Wasp
Unlikely to Die because it would look really bad:
- Wong
- Mantis
- Valkryie
I Find it Unlikely:
- Thor: it is easier to simply send him off the space to be King Thor somewhere. Plus he is JUST now super profitable and he is likely cheaper than RDJ, Evans, and Scarlet.
- Bucky
- Falcon
- Witch
-
Death Watch (imo):
- Drax: his whole family is dead, in the comics he existed to kill Thanos, Gunn doesn't really know what to do with him other than laugh loud (he is hardly the Destroyer), most easily replaced, and he can give a "I am going to be with my family now" talk before dying. Also most likely to scream and charge Thanos out of pure dumb rage like he did Ronan
- Steve, Stark, Widow, Hawkeye, Banner, Maria Hill, Fury: Old guard that has been around forever... one or more of them have to die IMO
- Vision: Obv
- Nebula: she isn't a core GoG member, her arc revolves around Thanos (especially after they squashed the gamora/nebula beef)... she doesn't have a ton of use after Thanos is gone. Dying here to either save everyone or kill Thanos would fit. OR... they kill Gamora and Nebula takes her place in GoG3.
- Gamora: see above
- Loki: idk who would actually believe he would be dead this time for real but... he is going to be hanging around Thanos a lot potentially and it would make since that his final "gotcha bitch side change" would end up with him dead. Plus how many more stories can you do with Loki at this point?
- Rhodey: because he's Rhodey lol
- Okoye: T'challa, Shuri, M'baku (where is NAKIA nooooooooo) are in this movie and those three are more important than Okoye. Okoye dying raises the stakes for T'challa and Wakanda as a whole. And gives BP2 a second subplot of a new Dora close to the king.
