— Excalibur Sonic, Sonic and the Black Knight

Excalibur Sonic[2] (エクスカリバーソニック Ekusukaribā Sonikku?), also written as Excalibur-Sonic,[1] is a transformation that appears in Sonic and the Black Knight. It is the form Sonic the Hedgehog assumed with the magic of the sacred swords, Caliburn included, for the final battle against the Dark Queen, an enhanced form of Merlina the Wizard.


Unlike most of Sonic's other normal transformations, Sonic himself does not undergo any physical change. Instead, he dons shining golden armor covering his entire body (except for his tail). A red cape runs down the back of his armor.

Powers and abilities

In this form, Sonic is renowned as the ultimate Knight, hinting a high level of skill and power.[1] He has increased strength, allowing him to deflect the massive sword strikes from the Dark Queen's spectral form, and the ability to fly, along with the ability to use his own Soul Surge. He also gains a move similar to his Quick Step, allowing him to roll to the right or left to evade attacks. While his attacks are more close-combat based, as opposed to the more energy-focused moves that Super Sonic uses, he can channel golden energy into his sword strikes for more devastating damage and range.

As Excalibur Sonic, Sonic wields Caliburn in his legendary form, Excalibur, the greatest of all the sacred swords. With it, Excalibur Sonic can cut through anything and deflect magical energy projectiles. He can also use Excalibur for his most powerful attack where he thrusts Excalibur directly through his opponent while enveloped in a golden energy meteor.

  • "Nah, it's not gonna end. My stories only end when I stop running!" - Sonic response when Merlina asks him, if he wants to see the Arthurian realm come to an end.
  • "Good, 'cause I don't ever want to know such one-sided sadness." - Sonic's response to Merlina when she proclaims her sadness about the kingdom's future.
  • "Heh heh! My trusty sword's gonna teach you a lesson." - Sonic backing up one of Excalibur's quotes.
