As most eagle-eyed fans had suspected, The Flash will bring in Clifford DeVoe, the villain known as The Thinker, as the big bad of season 4, TVLine reports.

They don't have any more details, and the report is tangential, as part of a fantasy-casting story, but they had a similarly-sourced casting story about Reign just days before the villain was officially announed for Supergirl season 3 yesterday.

Interestingly, the report does suggest that the foe will be squaring off with Barry Allen, suggesting that he's likely to return from the Speed Force prison sooner than later if their tip is right. Earlier this season, producers revealed that The Flash's season 4 big bad won't be a speedster, but gave very little in the way of possibilities as to who it might be -- but the seasonfinale may have provided an important clue when Savitar mentioned a "cerebral inhibitor" that was going to play a big role in defeating a foe they hadn't met yet.

When Abra Kadabra was talking to The Flash about his most dangerous foes, he rattled off a number of familiar names, including Zoom and Eobard Thawne...and one less-familiar one (at least to the TV audience): "DeVoe." Longtime comic book readers would recognize that name: Clifford DeVoe is a longtime Flash and Titans villain better known as The Thinker.

Created in 1943, The Thinker is one of The Flash's earliest villains. Originally a foe to Jay Garrick, DeVoe battled three generations of Flashes before his death in The Flash #134 in 1998. After his death, though, his brain patterns were used to create an AI that went on to become an antihero. The Thinker was a tech-enhanced villain, utilizing a number of high-tech gadgets along with a group of cronies. The most significant of his toys was his "Thinking Cap," a metal hat that could project mental force. A replica of the Cap was key in bringing his virtual self back from the grave. Over the years, he eventually joined the Suicide Squad -- something we're of course unlikely to see on TV right away. Both before that -- and then again after, when he fell off the "reformed supervillain" wagon and went fully bad again -- he was a member of the Injustice Society, often serving alongside The Shade, a character who has been seen on The Flash already.
