Gothmog?

[Tar-Alcarin]

Tar-Alcarin...the bit about Gothmog being drawn by great beasts was a joke. But I'm afraid I'm goign to have to debate your point about the Leiutenant of Morgul not being bale to break the Gates o f Minas Tirith. He could have a very think skull, you know.

He would have to have the biggest head ever. That gate is made out of stone and unless he had a jackhammer attached to his chin there is no way in mordor he could have. But the movie gothmog might have been able to. With that huge lump on the side of his head.
