After a disaster during one of the Avengers missions, the government has created a Superhuman Registration Act, stating that the Avengers can no longer operate has an independent organization. The Avengers become split over it. Tony immediately wants to sign it, and Peter 2, Rhodey, and Vision are in full agreement with him. Steve has his reservations though, and Logan and Sam agree with him. Natasha, on the other hand, is split between what she thinks is right and what her husband believes. Things get even more complicated when someone frames Bucky Barnes for killing the king of Wakanda, which gets a new hero, the Black Panther, involved in the conflict. Steve still believes in Bucky, and will do anything to prove his innocence, but Tony is fully willing to take Steve and Bucky down, and anyone who sides with them.
