who will be the S4 villain for flash

s1 -s3 were all speedster but s4 it is not but who can it be I search the web deeply Well, in the episode abra Kadabra, we got a major clue from a minor villain. As Abra Kadabra was being led off to face his fate, Barry tried to appeal to his better nature, begging for information about Savitar. While pointing out that nobody hurt Barry as badly as Savitar will, Kadabra rattled off the names of the villains who have most impacted Barry's life, including Thawne and Zoom. But there was another name.

"Devoe."

There's only one Devoe worth mentioning in Flash mythology, and that's Clifford Devoe, the Thinker. Devoe is traditionally known as more of a Jay Garrick villain, first appearing in All-Flash Comics #12 way back in 1943. He took on both Jay Garrick and the Justice Society numerous times, and he had a quaint (by modern standards) "thinking cap" which allowed him some amplified psionic abilities. But when his physical body died, he became a non-living artificial intelligence with even greater power. It's easy to imagine a kind of hybridized Clifford Devoe making trouble on the show next year, and if he's indeed the big baddie of The Flash Season 4, then I imagine the showrunners already have something interesting mapped out for him.
