Excalibur

The Excalibur is a legendary sword that is unrivalled by any other weapons in this universe which is currently under Azareal's possession and was originally created in the Kupostar within the Kupo Forge where countless masses of data and energy were poured into it's creation.

As such, it's powers are normally sealed within this universe as it can greatly distort the data in Cyberspace which would impact greatly on the Azanet itself and it can directly delete data upon contact.
