Favorite boss battle?

[jokaero]

The Circus from Dwarf Fortress (very few people have ever beaten it), but I really do enjoy the battle with Theseus from God of War 2.

 

[ParanoidEngineer]

Alpha Protocol, Brayko boss battle.

Why?

Music.

No, don't even say anything. You're fighting. In a disco. With a teenager on cocaine. Whilst he plays 80's music.

 

[Lt._nefarious]

Scarlet from Silent Hill Homecoming because the boss was challenging and disturbing...

 

[OctoH]

Final boss in RAGE! Wait...never mind.

OT: Saren. Maybe not so much the battle so much as the character. You could have a pretty hard fight if you wanted, but it really showed Saren as a tragic and conflicted character.
