Question: what does the post credit scene in avengers endgame mean?
Answer: Avengers: Endgame has no mid or post-credits scenes. ... It's not a scene, it's a sound. I won't tell you what it is. Only the most diehard fans will want to stick around to hear it. (SPOILERS: It's the sound of Tony Stark hammering away at his first Iron Man suit while imprisoned by terrorists in the first Iron Man film.)
