We got our first look at The Thinker in “The Flash Reborn,” and it’s already evident that he could be Barry’s greatest enemy of the series to date.
The Thinker didn’t appear until the very last scene, when it was revealed that the samuroid wasn’t actually the big bad of the episode.
The Flash has been teasing the Season 4 supervillain since way back in the middle of Season 3, when the baddie Abra Kadabra named “DeVoe” as one of Barry’s nemeses.
Fans of DC Comics recognized “DeVoe” as Clifford DeVoe, a.k.a. the supervillain known as The Thinker.
