Murray the demonic talking skull (The Curse of Monkey Island, 1997)
“You may call me 'Murray’! I am a powerful demonic force! I am the harbinger of your doom! And the forces of darkness will applaud me as I stride through the Gates of Hell – carrying your head on a pike!” – mighty strong words for a skull with no appendages. Still, we have to admire the spirit of Guybrush Threepwood's evil companion, bless him.
