I know this is a really old post, but I, too, am interested in something like this.

I was thinking about trying to make a category akin to All Bosses, but I am having trouble telling what is and isn't technically a boss.

I know Daimon, Grigori, Death, and Seneschal are 'bosses', but what about things like the Hydra, or the Cockatrice in Gran Soren? Some are required to progress and some are not, but what would be interesting to fight/watch fight?

Thoughts?
