How do you beat the Black Queen in Sonic and the Black Knight

Your main objective is to get as many hits using Soul Surge as possible. As far as I know, reflecting the orbs she shoots at you doesn't do anything except fill your Soul Gauge. I usually get hit trying to reflect them all, so I usually just dodge them.

You'll get most of your Soul Gauge from countering the Black Queen's sword swings, so it might be best just to wait for those. It's the same think where you wait until the sword she's about to swing glows, and then you shake the wiimote.

After you have a full Soul Gauge, use a Soul Surge and try to get as many hits in as possible. After a while, she'll start shooting more complex orb patterns and moving faster, but it's still the same strategy.
