Excalibur

Excalibur is the most famous sword in Earth history. It first appeared in An American Benwolf in London.
==Appearance==
It is shaped like a classic knight's sword. It is normally embedded in stone as a protective measure.
==History==
===Background===
In ancient times, the sword had been wielded by famous historical and legendary figures such as Sigurd and Beowulf, though its most well-known owner was King Arthur of Camelot. It has gone by many names, but it is best known as Excalibur. The sword was last used in the war against Napoleon Bonaparte of France and stored in the underwater vault of Britannia in the Thames River.
==Powers and Abilities==
According to legend, the sword will make anyone who wields it in battle invincible. Whether or not this is true or whatever powers it possesses have not been revealed. However, it is embedded within a stone in which only the truly worthy may remove it. It is such that not even a mutated Joseph Chadwick, or Ben, who used both Four Arms and Humungousaur, could pull it free (and attempts at breaking the stone itself proved just as ineffective). However, Kai Green was able to move it a little, which implied that she was worthy enough to wield the sword. This was proven true in The End of an Era.
Currently, Excalibur still resides in its underwater vault as Chadwick did not take it with him, when he escaped with the damaged Red Knight.
In the future, Excalibur has been relocated to Ben 10,000 Tower. It has been removed from its stone, and is used as Kai's personal weapon. The blade has been proven to be strong enough to cut through a thick, metal alloy door with ease.

==Trivia==
*Only one who is worthy can remove Excalibur from the stone.
**When Kai touched Excalibur, it moved a little; implying that Kai is worthy.
**In The End of an Era, it is confirmed that Kai is worthy as she is seen wielding it. Ben is also seen being able to hold it, implying that he may also be worthy of wielding it. 
*It is a misconception that Excalibur is the Sword in the Stone, as they are in actuality two very different weapons. Excalibur was given to King Arthur by the Lady of the Lake after the Sword in the Stone was broken. However, the two have become linked in the modern psyche, and so Excalibur is often depicted in a stone to the exclusion of the original sword and the Lady of the Lake.
