Dark Samus 2

Prime Hunter (No vids of this however)

I found that if you use Charged Dark Beam shots on her, the amount of damage dealt is a whole lot more than if you use Super Missiles or the Light Beam (Strange that the Dark Beam is very effective against Dark Samus, but...) I used almost my entire 100 ammo, but the battle was very quick this way (On normal difficulty).

If you stay near the wall at all times you can see all DS2's attacks and dodge them, most notably the Boost Ball Attack. It's fun to sit there while DS ricochets all over the place. If it comes near you just double jump and strafe along the wall to shoot DS.
