What characters used spell book in Beetleborgs?

The Beetleborgs themselves do not use a spellbook in the show. They are granted their powers by the Beetleborgs Medallion.

While the show doesn't feature a spellbook used directly by the Beetleborgs, there are a couple of characters who use magic and could be associated with a spellbook:

* The Skull Master: This villain often uses magic to create monsters and schemes. He might possess a book of spells, though it's never explicitly shown.

* The Witch of the Wasteland: This recurring antagonist sometimes utilizes magic, but her methods are not associated with any specific book.

However, there is no singular spellbook that is central to the Beetleborgs' powers or the show's storyline.
