The Story so Far
6 months ago – The Scarlet Witch suffers a complete breakdown, killing Hawkeye, Ant-Man and the Vision, and injuring many others. The Avengers disband shortly afterwards.
A splinter group of the terrorist organisation Hydra has formed under the leadership of the Viper. To further her plans, she has formed an alliance with the Gorgon, the leader of the ancient order of assassins known as the Hand.
The super-villain Electro was hired by the Viper to free the Silver Samurai from the Raft prison. While there he released all the other prisoners to cover his escape. A group of heroes arrived at the Raft to stop the breakout but, despite their best efforts, 25 other prisoners escaped.
One of the escapees was called the Sentry. Reed Richards had asked the Beast to speak with the Sentry as Richards believed he was actually a hero who had somehow been forgotten by the world. Sentry saved Beast from a grisly death at the hands of Carnage before flying off into the sky. Subsequent investigations could find few mentions of the Sentry except in old comic books from the 1950s.
Meanwhile, the life of Captain America was turned upside down by two events: the death of his nemesis the Red Skull, and the revelation that his war-time sidekick, Bucky, was still alive and working for the Russians as the assassin known as the Winter Soldier.
