AU, no second thor movie, third iron man, or Age of Ultron. I'm trying to keep this the movies but some elements from the comics might slip in.

I don't know if Clint's family was given names in Ultron beyond the baby, I'm calling his wife Amanda.

Also, politician bashing

I am basing the character (the president) Larry Trask on two characters from the comics.

1) Larry Trask is the son of the man who invented the Sentinels--Dr. Bolivar Trask. He is a mutant though he didn't know it, his father had him wear a medallion that blocked his minor precog powers. He died when he removed the medallion, the sentinels recognized him as the enemy, he lost control of them, and a sentinel fell on him.

2) Graydon Creed. Not a mutant but the son of two of them (Mystique and Sabretooth) and very big in the anti-mutant friends of humanity group. He was running for office and might have actually won if he hadn't been killed.
