Flash Villains Quiz Book [PDF ebook]

Unlike other comics characters the Rogues share a group dynamic and their histories in comics are interwoven with each other. So prepare to test yourself on these villains, not supervillains, they hate that term and see how far your knowledge stretches on these characters that are often a thorn in the side of the scarlet speedster.
