In honor of 666 pages in Rumbles (post 2015 reboot), I pose a question:
What is the most powerful fictional being with the title (or name) of 'The Beast'?
Fiction has quite a few beings who use this moniker. But who is strongest?
Present your choice!
Edit: Forgot my Nod to Beadle, so I'll put it here. *nods to Beadle*
