Worst written villain?

What villain do you think was the worst written? Too shallow? Not enough personality?

LIMBUS COMPANY SPOILERS!!!!!
I cannot stand Dongrang tbh. I think he's one of the weakest main villains for me in limbus. He was boring at the start, then the reveal was okay, but then my interest went downhill immediately, and his short-lived villainy wasn't compelling enough. Ahab was much, much better holy shit i love my gaslighting queen~
