Just a couple boss fights I remember that haven't been mentioned yet:
Omega Pirate from Metroid Prime 1. I finished the fight with around 30 energy left.
King Bohan from Heavenly Sword. Hear me out on this. The actual fight wasn't all that great, but boy did the game do a great job of giving it an epic feel. The music was awesome and it was cool seeing a huge army surrounding you while you were fighting him.
Not really a boss fight, but the last mission in Freespace 2. Holy shit, when they tell you to bug out, I was like "Crap crap crap crap." Transferred all my energy to engines, used my afterburners....and didn't make it out
