'The Flash' season 4 spoilers: Barry Allen could face his most intelligent nemesis yet

The season finale of “The Flash” has aired, unveiling a cliffhanger that might leave a lot of fans sleepless. It turns out that Savitar, the hero's most mysterious and possibly strongest nemesis, knows everything that he has ever done.

This villain is a serious threat to Flash and the rest of his team, and although they did take him down, it came with a cost. Barry Allen ended up swallowed in the Speed Force, which let Wally West stand up as the new Flash. There is going to be some struggles as there are things that might take some time to getting used to.

Spoiler alert! This article contains “The Flash” spoilers. Read on if you would like to know what happensbefore the next episode airs.

At this point, fans are wondering how Barry can be brought back as the real Flash of Central City and how such dire effects can be reversed. It could be hard to believe that the character the entire show was built on would be written off after the third season.

However, Savitar did drop a few hints about the future, and he sure could be relied on since he knows everything about such events. Some of his words could mean that viewers are about to see Flash’s most intelligent villain yet in the upcoming fourth season: the Thinker.

According to Screen Rant, The Thinker, aka Clifford DeVoe, is a founding member of the Injustice Society and a regular nemesis of Jay Garrick as Flash. He has a very high IQ but was a failure as a lawyer. He decides to wreak havoc in Central City. To pursue this, he creates a thinking cap that gives him the ability to securely protect his mental force.

What sets him apart from other Flash villains is that he is more intelligent and he has the ability to use his brain to help others commit crimes. He is not as actively seen as other villains but pulls strings from behind them. He does profit from them, but he does not get his hands dirty.

Barry has faced several villains who are not speedsters, including members of his rogue’s gallery. If this speculation is true, then The Thinker would be Barry’s first non-speedster nemesis.

Season 4 of “The Flash” is set to return this fall on The CW. It will also air on FOX8 on Australia.
