Jerrik

jerrik??? undead pirate king, most likely a hippo with no fins or damaged fins?

undead crew, unfortunate lost souls and his own reanimated dead

lots of drowned dead and dead hippos

immortal, gave up his eternal rest to pillage the seas until the end of time

can be killed -- but HOW??? 

love of his life is dead and long gone

became corrupt trying to save them

potc meets other potc movie meets sad tale of unrequited love meets my necromancer obsession
