I absolutely loved Human LeChuck. He was refreshing, he was a change of pace and it was just a great take on the character. As much as I was initially scared of the idea after a weakened LeChuck in EMI, I ended up really enjoying it.
I really felt like LeChuck had suffered as a character in Curse and Escape. He was still very entertaining in both games and better than the somewhat interesting character present in Secret, but LeChuck seriously suffered from badass decay. His frame swelled to that of a ludicrously large size and he became much more of a buffoon. Gone were the days of dropping Guybrush in acid and here was eating slaw and serving as Ozzie's manservant.
In Tales LeChuck is again a totally evil badass. He UTTERLY plays Guybrush and everyone else for a total fool. LeChuck shows that he is definitely in some ways cunning. LeChuck even achieves his ultimate goal in MI2 of killing Threepwood.
What is really shocking though to me was what LeChuck did after killing Guybrush. LeChuck eagerly discards a rare opportunity for humanity and beauty in exchange for a hideous appearance and demonic voodoo powers. He asks Elaine for her hand in marriage but then appears to be totally willing to engage in a fight where she could die, something not seen before with LeChuck.
I really feel like Tales has given credibility to LeChuck again and revitalized my favorite character.
