Comic Master Weapons are weapons that can only work to their fullest potential when being used by a Comic Master. Comic Master Weapons generally grow stronger as the Comic Master who wields them grows stronger. Comic Master Weapons also have magical abilities that can only be utilized by Comic Masters. People other than Comic Masters can also use Comic Master Weapons, but they can only use them as regular Weapons and they can only use them at their base strength which is usually very low.
Comic Master Weapons are one of the only types of weapons that don't have a clear creator other than by Real Life Joshua himself. Some believe these weapons have existed before the birth of the ComicVerse and may have even played a part in creating the ComicVerse.
