"The Third Reich represents the greatest threat to liberty and justice the world has ever seen."
"And if their "HYDRA" developed those weapons to fight Spanish rebels back in the thirties..."
"...God only knows what horrors they've cooked up now."
Chester Phillips and Howard Stark[src]

The HYDRA Exo-Skeleton is an Arc Reactor powered weapon used by HYDRA during the Spanish Civil War and World War II.


"I am working on advanced exo-skeleton technology... To make o-one soldier fight ...like a battalion..."
Arnim Zola to Johann Schmidt[src]

The exo-skeleton was one of the first scientific wonders that Doctor Arnim Zola developed for the Nazis. He worked on this project at the Sturmabteilung's Weapons Testing Ground at Kummersdorf.

In July 1934, shortly after the infamous Nazi blood purge known as the Night of the Long Knives, Kummersdorf was attacked by the Schutzstaffel troops led by Johann Schmidt. Almost the entire personnel of the base was killed, but Zola was spared because he agreed to join Schmidt's SS division HYDRA and start working on genetics.

In September 1935, Zola was allowed to resume his work on exo-skeleton battle suits and various high-tech weaponry because Schmidt captured Abraham Erskine, a German scientist who worked on the Super Soldier Serum.

In 1937, the exo-skeleton battle suit was finished. It was used by HYDRA during the Spanish Civil War against the Spanish Republicans at Guernica. At the time, it was believed that the German air force, the Luftwaffe, was responsible for the destruction of the city. However, the footage of the slaughter was smuggled out of Germany by the British agent Margaret Carter and handed over to the United States Army in January 1940.

In April 1944, the exo-skeleton was in a HYDRA castle on an island in the Nazi occupied Danish Straits. The castle was invaded by Captain America, who managed to destroy the exo-skeleton and a tank.[1]
