Fritz is known to be the buffest beefcake on deck, but that shouldn't discredit his intellect or his sense of honor. He wears some leather-strapped chain for armor, but it has been worked on by his twin brother Viktor to make it lighter and allow for better movement while curb-stomping fools. He loves his brother like, well, a brother, but he frequently gets into arguments with him about his sense of reckless abandon and, most frequently, who's the older twin (Fritz is older, obviously).
He was born in a family with numerous different siblings, including his twin Viktor Hancock, who he now works with in Captain Shrapnel's crew.
