Dark Queen

The Dark Queen is featured as the final boss of sonic and the black knight. The Dark Queen is Merlina in a witch-like form, but in battle she appears as a ghostly version of king Arthur equipped with an eye on its chest, two giant swords greatly representing the sword used in the battle against king arthur, and dozens of arms. the battle resembles the final boss in sonic and the secret rings since both are played in a different dimension and both introduce a new super form for sonic(Darkspine sonic in sonic and the secret rings and golden knight sonic/Excalibur sonic in sonic and the black knight). The objective you need to proceed to beat her is to flick the Wii remote when one is shown on the screen to power up sonic's soul gauge, then after slashing her multiple times it will show her slightly dissolving and then the screen will feature the final cutscene and credits.
