Obviously LeChuck is an idiot... but he is a very powerful one... and is well known as a brutal unkillable freak of nature... as the games went on they kind of lost that part of him from the first game where everyone was legitimately afraid of him... I think by the time Curse came out Guybrush didn't act like he was a threat so we kind of stop taking him serious.... I feel with ToMI we got some of that back.... LeChuck turned human and used it to his advantage and it was Guybrush that underestimated him and died because of it.
