What is your favorite boss fight ever?

I liked fighting Yami in Okami, but there are so many great boss battles that it's hard for me to choose one to be the best.

Zed Blade - Neo Geo
The last boss is the best heart
Her music is cool and shes so scary, when i played this i was glad i didnt have to use quarters ^^

Gruntilda from Banjo-Kazooie. Knocking her fat a** off her tower was the best feeling in the world. Her taunting and nagging in between the worlds was enough to drive a little kid insane.
