I also think Drax dies, but I don't think he would be the only one just because I have a hard time imagining Gunn doing some truly emotional farewell to the character. Like, if that scene of Quill screaming is when someone is dying, I just can't imagine that level of raw emotion being put on a Drax scene. IDK, maybe Gunn will surprise me, but that's how little I expect from Drax being taken seriously as a character. lol

(Another reason why I think Drax dies is because I fully believe those old leaks/rumors about Moondragon appearing, and since Dave Bautista has indicated he's pretty much ''done'' with the role, I think it would make no sense for him to leave the team right when his daughter is introduced. I think it makes more sense that he ends up sacrificing himself to save her or something like that)
