Sir Sonic [Knight of the Wind] and Excalibur

also known as Excalibur Sonic is a transformation for Caliburn that turns him into the legendary Sword Excalibur (and grants Sir Sonic a nifty golden suit of armor)

to Achieve this form caliburn has to merge with the 3 other Sacred Swords: Arondight,Galatine, and Laevatein but thats not all he needs to transform, he also needs a lot of "WillPower" luckily Sonic's never give up attitude helped  brought forth this special form
