History
Duck Key was a small island part of the Florida Keys. The Hulk, seeking a private refuge, invaded the island, destroyed the one bridge off the island and told the residents that it was now Hulk Island and that all residents were required to get along - and that none were permitted to leave.[1]
When Deadpool was ill and needed a gamma-irradiated blood sample, he travelled to Duck Key to obtain blood from the Hulk.[2] During Tropical Storm Betty, the Hulk fortified the island to protect it from harm. While there, he was attacked by Hulk of Earth-9722. Colonel St. Lawrence was able to convince the Hulk that if he truly wanted to be left alone, he could find a more remote spot. The Hulk then left.[3]
