Baron Strucker

Baron Wolfgang Von Strucker is a supervillain from Marvel Comics. In most incarnations he is the commander and best known leader of the terrorist organization HYDRA and Nick Fury 's arch-enemy.

Wolfgang von Strucker was created by Stan Lee and Jack Kirby.

Captain America: The Winter Soldier
Wolfgang von Strucker only appears in the first post-credits scene of the film. He is revealed to be one of the high-ranking officers of HYDRA after it infiltrated SHIELD. When he learned that various spies had been uncovered thanks to Fury's actions at SHIELD, he dismissed the problem, as he managed to uncover Loki's Scepter, which he planned to use to further HYDRA's agenda.

He also revealed his intentions of burying all the deceased HYDRA agents "so deep that their ghosts can't reunite with their bodies," and that he intended to have Scarlet Witch and Quicksilver, whom he had retrieved earlier, for an important role due to their having their "age of miracles."

Agents of S.H.I.E.L.D.
After escaping from military custody, Ward went to a bar to meet Sunil Bakshi. Ward knew that Strucker was overseas, so he requested a meeting with the new head of HYDRA. Bakshi replies that he will ask to Whitehall because his boss was very busy.

The Avengers: Age of Ultron
He is confirmed to appear in The Avengers: Age of Ultron.

The Avengers: Earth's Mightiest Heroes
During World War II, Strucker served as a lieutenant to the Red Skull. After the war, he became the leader of HYDRA.

At some point, Wolfgang von Strucker was captured and jailed in the Vault. Grim Reaper tried to free him but they were foiled by Nick Fury and Maria Hill, and captured.

Later, the Vault experienced a massive power outage releasing all of the inmates. Strucker and Grim Reaper escaped and returned to HYDRA.

The two were at a HYDRA meeting when Baron Zemo appeared wanting help since Captain America had returned. They refused and Zemo set out to defeat the World War II hero himself.

HYDRA tried to make a deal with A.I.M. to make a powerful cube. However, A.I.M. claimed they could not do anything and gave back the money HYDRA sent them. Knowing MODOK was lying, Strucker got HYDRA into conflict with A.I.M., and the Black Widow, a double agent in Strucker's forces, told it to the Avengers to stop bot factions.

During the conflict, Captain America and Strucker touched the cube at the same time, but the clash of wills made the cube not work, so Strucker thought it didn't work at all. Wolfgang von Strucker was subsequently arrested.
