In preparation for the coming "Flash War" storyline in 2018, The Flash writer Joshua Williamson today teased a deep dive into the character's history.

Among Williamson's pile of books are classic Flash reads like Crisis on Infinite Earths and The Flash Omnibus. There are several Barry Allen stories, including The Flash: Rebirth, Flashpoint and The Dastardly Death of the Rogues.

However, also among the collection are several Wally West books, including The New Teen Titans Omnibus, Terminal Velocity, Rogue War, Wonderland, The Return of Barry Allen and The Secret of Barry Allen.

"Flash War" is expected to decide once and for all whether Barry Allen or the Pre-Flashpoint Wally West is the better Flash. The story kicks off in January with The Flash Annual #1 by Joshua Williamson and Christian Duce. The synopsis for the issue hints at a major conflict brewing:

“FLASH WAR” prelude! The biggest Flash story of 2018 starts here, with a special story starring the classic Wally West, who’s conflicted over whether to let Iris West know he is alive—and he’ll need the help of the Flash to figure out what to do! But when Magenta, Wally’s old love, needs his help, the Flash returns home to Keystone City where he is confronted with violent memories of an unknown world… A major turning point for the Flash family that sets the path for earth shattering stories in 2018!

The full story gets started in February with Howard Porter on art duties.
