10 Coolest Weapons In The Arrowverse

The Book of Destiny was the main plot device in the Elseworlds Arrowverse crossover, while also being utilised in the Crisis on Infinite Earths event by Lex Luthor. The book grants the person wielding it the ability to shape reality as they see fit, which is honestly the most powerful weapon anyone could have at their disposal.

During the Elseworlds crossover, the Monitor gives the book to a man named John Deegan who shapes reality the way he wants to. He firstly wanted to become The Flash, however he accidentally swapped Oliver and Barry's identities and abilities.

This book eventually saw Deegan making both Oliver and Barry powerless, turning their allies into pawns and trapping Supergirl (oh, and he gave himself the appearance and abilities of Superman and made himself Earth's saviour). These actions prove that the Book of Destiny is a powerful tool that is only limited by the person's imagination.

It has been used to wipe out planets across the multiverse, and the Book of Destiny was a powerful weapon that could wipe out superpowered beings from existence if the wielder of the book had the imagination to do it.
