Joe Gibken

"Gokai Blue!"

Joe Gibken is the second-in-command of the Kaizoku Sentai Gokaiger.

Biography
Joe was once a member of the Zangyack's Imperial Special Forces, but when he was instructed to kill a group of captive children on his first mission, he refused and was imprisoned for attacking his superior officers while having their prisoners escape, only managing to escape thanks to the apparent sacrifice of his friend Sid. While on the run with a 1,000,000 bounty on his head, unable to settle anywhere in one place due to the tracking collar on him, Joe was saved from his executioners by Captain Marvelous, whom he vowed to follow after Captain Marvelous managed to get the collar off through painstaking effort.

After discovering that Sid had not died but became Barizorg, unable to save him to his dismay, Joe realizes he had already found a new family in the form of the Gokaiger crew without realizing it, and decides to let go of his past.
