HYDRA Island is an island fortress of HYDRA located somewhere in one of the world's oceans.
It is where Baron Strucker, his loyal agents (Grim Reaper, Madame Hydra, and Black Widow), and his forces were based there to plan their schemes of world domination.
It was later destroyed under Code Fenris as Captain America, Black Panther, assisted Hawkeye and Mockingbird in taking down HYDRA.
