Excalibur-Sonic

Excalibur Sonic is one of Sonic's super forms, appearing in Sonic and the Black Knight. Rather than Chaos Emeralds, he uses the power of the transformed Caliburn the Sword and the three Sacred Swords. He is playable in the final battle against the Dark Queen, an enhanced form of Merlina the Sorceress corrupted by the scabbard of Excalibur.

In this form, Sonic has increased strength and the ability to fly, along with Soul Gauge powers. His attacks are also more close-combat based, as opposed to the boosting and energy moves that Super Sonic uses.

He dons shining gold armor covering his body and Excalibur in his right hand. A red cape runs down the back of his armor.
