Baron Strucker

Baron Wolfang Von Strucker is the present-day leader of HYDRA, and Nick Fury's arch-enemy.

The Avengers: Earth's Mightiest Heroes
At some point, Baron 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. Baron Strucker was subsequently arrested.
