Spoiler Alert: If you haven't seen last Tuesdays episode of The Flash, then stop reading and go catch up! I don't wanna spoil anything for you.
Okay so this is my first time writing for Movie pilot so if this isn't the best article, i'm sorry, but I promise i'll get better. Anyways i'll get to the point, for everyone who watched Tuesdays episode then you know that Dr. Harrison Wells does in fact have speedy power much like Barry. Now there's been a lot of speculating on who Dr. Wells is, my two favorite theories are
#1: Dr. Harrison Wells is reverse flash (future Eddie Thawne or a relative of Eddies) and he is working with himself from the further future.
I know it sounds pretty far off, but not really if you think about the other theory which is
#2: Dr. Harrison Wells is Barry Allen from the future. Now this theory I actually strongly believed until I payed close attention to pictures of Dr. Wells using his powers from Tuesdays episode.
THE STREAKS ARE RED! Not only does Dr. Wells have the reverse flash suit and the Techyon device that Reverse Flash stole, but he has red streaks. We also know that his powers are uncontrollable and are fading. Now everyone's probably wondering why the streaks matter so much, and here's why. The Flash's powers come from a positive charge making his streaks yellow. The Reverse Flash tried to manipulate the same situation that gave Barry his powers only he had something wrong and his powers came from a negative charge making his streaks red. This also caused him to become insane, but you see these steaks mean that theory #2 is wrong, he isn't Barry and in fact is Reverse Flash.
There's some pictures so you can see for yourself. Now that we know he is in fact Reverse Flash, which one is he?
The Rival: Dr. Edward Clariss, a professor at the university attended by the first Flash, Jay Garrick. He believed he recreated the formula that gave Garrick his speed, which he called "Velocity 9."
Professor Zoom: Eobard Thawne is a criminal from the 25th century who found a time capsule containing the Silver Age Flash's costume. He is able to use a machine to amplify the suit's speed energy, providing the abilities of the Flash as long as he wears it. In the process, the colors of the costume reverse, with the suit becoming yellow, the boots and lightning bolt highlights turning red, and the chest symbol's white circle becoming black. He uses his speed to commit crimes. He interprets this to imply that Barry needed to become the Flash for him to become the Reverse-Flash. He frames Barry's father for murdering his mother.
Zoom: Hunter Zolomon was severely injured in an attack by Gorilla Grodd, leaving him paralyzed from the waist down. He asked West to use the time-travelling cosmic treadmill in the Flash Museum to prevent this from occurring. West refused, saying that he could not risk damaging the timestream. Zolomon then broke into the museum and attempted to use the treadmill himself. The resulting explosion destroyed the museum (as well as his remaining sanity) and shifted Hunter's connection to time. He could now alter his personal timeline, giving the effect of super-speed. Zolomon concluded that West would not help because, unlike Allen, he had never suffered personal tragedy. Zolomon decided that if he became the new Zoom and killed West's wife (Linda Park), this would help the Flash become a better hero. Unlike other speedsters, Zoom's abilities lie not in speed but manipulation of time. For this reason he appears to be faster than The Flash and untouchable.
There are a couple other Reverse Flashes, but they didn't wear the yellow and red suit and were in Bart Allen's time zone.
