Hey everybody! This is my first post, so I thought I would start by giving predictions for one of the greatest superhero TV Shows of all time, The Flash!!!
(Mild Spoilers ahead for the season finale of The Flash)
As we saw in the finale, Eddie was the hero as he sacrificed his life to put a stop to his future relative the Reverse-Flash. How could he be alive you say? Here's my theory:
That strange vortex thing at the end of the episode swept Eddie's body away right? I think that it might be a wormhole for Earth-2 as Grant Gustin recently confirmed that it would be explored. Eddie may have been swept away to Earth-2, where he is reborn as another speedster: Cobalt Blue! Now Eddie may use his powers to either fight with Barry, or help Barry by traveling through dimensions.
I was shocked and confused when we saw Caitlin Snow as the Killer Frost in Barry's time travel adventure. Caitlin seems so happy and jolly, how could she become the ruthless and cold villain from the comics? I think I have found a possible answer. If you remember Episode 15, where Cisco (More on him later) was murdered by Wells? Earlier in the episode, Caitlin was trying to distract him by taking him to breakfast, which didn't work so well. Barry did reset the timeline at the end of the episode, but that alternate timeline still exists. Cisco can see it remember? My guess is that Caitlin rushes back to STAR Labs and finds Cisco dead on the floor. All her rage and anger towards Wells may cause her to go and restart the particle accelerator or using another means, to give herself the ability to find and end Wells. But, speaking of that certain villain, we also may be set up to see a certain hero who was teased in the finale.
Wells told Cisco that he could see alternate dimensions and that he had a great destiny ahead of him. The exact sentence escapes me, but it was something about vibrations between dimensions. If Cisco truly does become Vibe later on in the series, he could sort of be an informant to Barry. Cisco could easily inform Barry of Killer Frost in the other timeline, causing Barry to set things right by traveling back to the original timeline. I really don't have any other predictions for him, but as long as he keeps up the movie references he's good.
Now, let's talk new characters
I have one thought for Wally West, he WILL be in an alternate dimension of some sort. Unless Joe has an unknown child that nobody knows about, Wally West is the child of Iris's sibling. From Season 1, there has been no indication of another member of the West family. If Wally does appear, I think it might be in a timeline or dimension where Barry never moves in with Joe and there is another person in his spot. This sets the stage for Kid Flash, or maybe even the Wally West version of The Flash in an alternate timeline. Or Joe could have a secret child that no one knows about. Imagine Iris if she found out about that.
Gorilla Grodd was impressive in his one episode where he was the star. On a television budget, a telepathic gorilla is quite the achievement. Now everybody knows we haven't seen the last of said gorilla. I think once the mess in the current timeline that we've been seeing is fixed, Grodd can come in. Gorilla Grodd, Mirror Master, Dr. Alchemy and other villains could easily be the non-interdimension threats that Team Flash could face.
Hold On..... We could see Green Lantern too, Just not the One you Think
Before I start getting attacked about the Hal Jordan Easter Eggs and Diggle, just hear me out. We saw Jay Garrick's iconic Flash helmet pop out of that wormhole that Thawne was supposed to leave through right? And Earth-2 has been confirmed right? I think the Green Lantern Easter Eggs were put there to indicate the arrival of Alan Scott as the Green Lantern. He could easily appear fighting alongside Jay in Earth-2. What do you think though? I would still love to see Hal Jordan appear, and making Diggle a Green Lantern?? YES!!
