Mine is probably one of the last ever in this saga, which is Spider-Man’s identity revealed, because of the return of the one and only JJJ aka JK Simmons. It also served as the way to an interesting story about his identity being public.
Too many to choose from.
I agree
Mine too!
I guess Nick's cameo from Iron Man because it teased a larger world than just Iron Man
Adam Warlock's debut
Wanda's and Pietro Cameo from Winter Solider, Also the Avengers Cameo in Captain Marvel cause of obvious reasons lol.
What do you think?
