Task 1: I'd guess it would have to be Captain Marvel. My knowledge of the Avengers really goes back to the comics of the 1950s and I remember the Captain.

Task 2: I am sad that Ironman dies. Because Ozzy Osborn and Black Sabbath did a little tune about him and that's all I know of the movie. I've not watched a single Marvel Movie so I'm not exactly up to speed.

Task 3: I challenge Mork @morkrock because he IS up to speed!

Thanks @gabrielatravels for nominating me and giving me the chance to show off my knowledge :)
