Aquaman is definitely not the same superhero I grew up watching and reading about. He seems to have undergone a change from his mild mannered full bodied self to a somewhat darker and more disturbed long-haired character with a prosthetic left hand. Aquaman Wiki says some bad guy named Charybdis fed Aquaman's hand to piranha. Which comic book or animated TV episode or Movie first told the tale?
Not the mild mannered Aquaman I remember.
