Best Boss Fights

[The Elite MYT]

What are your top boss fights on the Saturn? From the games I have, the following are pretty standout (in no order):

Nights - The fat opera woman boss
Clockwork Night 2 - The paper animals
Gex - The turtle boxx
Shinobi X - The robot dude

I also like the final boss in Panzer Dragoon Zwei, but NOT the final form, which is just irritating.

Drenholm in Uru Ruins from Panzer Dragoon Saga. The atmosphere of the setting sun in the background and on the water, the killer music of Ancient Weapon, and just the whole design of the boss and its moves really gel with me.
