And who would the Avengers root for? And if there are differences who would MCU Avengers root for? And I find Jean Grey’s rooting amusing considering the actresses.

What if the Avengers came across ASOIAF? Who would like whom?

Hah! Sure, why not. Might as well finish out the set. 

Iron Man – Tyrion, kind of over-determined. 

War Machine – Bronn, because he too has to put up with Tyrion.

Spider-Man – Bran Stark, because the kid who develops powers and great responsibility because of an accident hits home. 

Vision – Bloodraven, because mysticism and being part human part something else.

Scarlet Witch – Daenerys, because struggling to control firepower(s) hits home.

Black Widow – Arya, also over-determined. 

Captain America – a Davos fan at the beginning of Winter Soldier, but more of a Beric Dondarrion fan by the end of Civil War. 

Falcon – Thoros of Myr, because he too has to put up with Beric Dondarrion.

Bucky –  Sandor, because all angry boys are secretly sad boys underneath.

Thor – Gendry, because he too appreciates hammers. 

Hulk – Sandor, because all angry boys are secretly sad boys underneath.

Hawkeye – Anguy, because no one else appreciates longbows.
